Simon Byholm asked:
In this article I’m going to discuss the properties of the diesel and gas engines, and compare them to each other. I’m specifically referring to their use in automobiles.
Looking at them from a distance both the gas and the diesel engine work in about the same way. A fuel made from refined crude oil is burned inside a cylinder and the hot expanding gasses forces the piston to move. The movement of the piston is then transferred to the wheels through crankshaft, gearbox and transmission.
It’s when we look at the engines a little closer that we start to notice that there are differences. Differences in gas mileage, smell, vibrations, price and expected age to name a few.
Ignition System
The gas engine has an ignition system with high voltages, wiring and spark plugs. The diesel does not need this, it compresses the fuel/air mixture until it’s so hot it ignites all by itself. In the gas engine it’s the spark plug that ignites the fuel-air mixture through a high voltage spark at the right time.
Another thing that separates the diesel from the gas engine is that gas engines adds the fuel vapor to the air in the intake manifold either through a carburetor or through fuel injection nozzles. The air/fuel mixture is then ****** into the cylinder to be burnt the next time the piston strikes.
The diesel on the other hand ***** clean air into the cylinder and then waits for the piston to compress the air as much as it will go. At this time when the air is compressed and hot enough to ignite the fuel, diesel is injected directly into the cylinder (or a small space connected to the cylinder) through high pressure nozzles. The fuel ignites instantly due to the high temperature in the cylinder.
The differences is fuel injection and ignition results in the diesel burning the fuel more efficiently than the gas engine. That’s why a diesel has a better gas mileage than it’s gas powered counterpart.
This is not to say that a diesel is better. It’s different, it has drawbacks too. Diesel engines usually is harder to start in cold and freezing weather. If you remember it was compressed hot air that ignited the fuel. When it’s too cold outside the air will never become hot enough to ignite the fuel, and the engine won’t run.
Cold Starting a Diesel
To handle this diesels have something called glow plugs for handling cold start situations. Electrical power from the accumulator is used to preheat the glow plugs inside the cylinders before the engine is started. This way the hot glow plugs ignite the fuel when the air is not hot enough to do it. Then when the engine starts it only takes a few seconds for the cylinders to get hot enough to ignite the fuel without help and the glow plugs are not needed again until the next cold start.
This is one of the nuisances of having a diesel in your car. The glowing takes from a couple of second to half a minute and can easily lead to stress when in a hurry. You just have to wait until it’s ready or the car won’t start. On the other hand if the engine is well done the glowing does not take long and you soon get accustomed to it.
Lets for a second look at the practical differences between the diesel and the gas engine. The diesel is large and loud, it emits black smoke when accelerating and is generally regarded as bad smelling by those not owning one. It also has a sturdier construction due to the higher pressures it must handle and thus can often go twice as many miles as a gas engine during it’s lifetime. The sturdier construction also makes it more expensive when first bought.
Features of The Gas Engine
* More quiet that the diesel
* Better acceleration and higher top speed
* Uses an Ignition System with Spark Plugs to Light The Fuel
* Adds fuel to the air before letting it into the cylinder
* Not as sturdy as a diesel. Lower price but breaks down faster
* Gas readily available everywhere
Features of The Diesel Engine
* Loud noise, sounds like a truck or agricultural machine
* Slow acceleration (get one with turbo charger, that helps)
* Lower top speeds but can easily reach the legal speed limit in most places
* Uses glow plugs to help the fuel ignite when the engine is cold
* Lets clean air into the cylinder and injects the fuel later
* Engine is simple and robust. Higher price but runs many miles
* Emits black smoke when loading it (like a quick acceleration)
* Easy to convert to using Eco fuel oils
If I where to give you advice on selecting either a gas or a diesel powered car I would probably tell you this: Get a diesel if you drive long trips and can live with the small nuisances of more noise and poor acceleration, get a gas powered car if you drive less than average or if you just want the comfort at any price.

Many say that Muscle and Tuner cars are just two the same car. But there is also a big number saying that they are not, and one is better than the other. This is an argument that even until now, car enthusiasts are battling out. There are forums that were not ended yet because all participants have their points, favoring their personal choice of car type. And both car types continue to developed themselves, making it look like comparison being made set out a competition between them. That is why I think, it will take forever before we all find out which one will conquer the streets and racing competitions.
First of all, the reason why Tuner and Muscle cars are being compared is that both cars are modified for better performance. By definition, muscle cars are especially made as spacious, durable, unsophisticated and powerful. These characteristics by muscle cars are what made them a bigger and heavier car. Tuner on the other hand is car of comfort, practicality and high gas mileage accompanied by performance modifications. They are typically good-handling vehicles. They’ve got light weight and worldly-wise suspensions.
Muscle cars’ specialty is drag racing while tuners are meant for drifting competition. But since they are both searching for car supremacy, both crossed the borders beyond their expertise. Tuners are now trying it in drag racing while muscle cars are giving it a shot on twisty tracks and thrilling drifting competitions.
Often times, it is the weight that most car enthusiasts are bragging about. For this part, it seems that tuners win it. Since they are exact, light and efficient, they are more capable of performing better as compared to muscle cars. Its low-cost tuning equipment triggered to more sales and high performance in comparison to dedicated sports cars. Other than their light weight, they are also easy to handle. But on the negative side, tuners are short in light of the massive torque and power that the bigger V-8s produce. This is where the edge of muscle car comes in. Muscle car always come with an engine that has powerful linear torque and horsepower curves. This characteristics made them better in acceleration and top speed. This leaves tuners behind because of its small engines and sharper torque curves, poorer when installed with a turbo-charger.
But it seems that the real standard for a good cars is its weight and handling. This is maybe the reason why modern muscle cars are now taking advantage of modern suspension working on better handling and avail computers which makes it more complex. This despite of the fact that there are muscle cars like rear-drive sedans that can have massive amounts of power.
For now, the debate is still up. We still can’t tell which one is better because both car types are developing their own. But to sum it all up, this battle between muscle and tuner cars benefits us the most.

James Russell asked:
Gasoline and diesel prices have been fluctuating for the past year but oil rates have become more stable for the past few months. This may sound like good news to you but there is still no assurance that oil prices will stay the way they are. It is still better to be ready for such increases in the future.
Keeping your vehicle well-maintained is an important thing to consider during such crisis-stricken times. Every part and bolt of your ride should always be kept in good shape to avoid breakdowns. You must always keep your vehicle’s engine well-oiled. Having it regularly checked by your local mechanic can keep you from spending more on having it overhauled for some minor problem that got worse because of neglect.
Aside from keeping your automobile in good shape, there are also other measures by which you could save more. One of these is by installing worthwhile improvements for your vehicle that can increase its performance and even help you save a lot more on your car. Tornado Fuel Saver is such an enhancement part.
Tornado Fuel Saver is a patented automotive air channeling tool that helps you save more on your gas mileage and can even increase your vehicle’s horsepower. The Tornado does this by improving air flow in your vehicle’s intake so that the air can fully mix with the fuel so that it can burn more effectively and efficiently. Better fuel and air combustion can result in more mileage and better car performance.
The Tornado is no turbo charger but it can do as much for your vehicle. It is just a simple but effective device that can be easily installed in any air intake system, whether it is a fuel injection engine or a carbureted engine. The Tornado transforms direct intake air into a swirling tornado. It is just a small metal ring with aerodynamic slotted fins that can fit in your air intake hose. With its precisely engineered slotted fins, the Tornado can change normal air flow into a spinning motion, somehow creating a Coriolis Effect that improves better air intake which results in better air and fuel integration inside the engine. And like a turbo charger which pumps more air into your engine, your engine can get more air and with the Tornado, the fuel can burn more effectively which results to more horsepower for your vehicle. Because you burn fuel effectively, you can save more on gas.
Several independent laboratory tests have proven that the Tornado can do miracles for your vehicle. Because it initiates better fuel atomization, it can increase mileage from 7 to 24 percent. These figures are based on road tests that were performed at an EPA licensed emission lab. Dyno testing has also found that it can increase an automobile’s horsepower by as much as 4 to 13 points. These are huge figures that can really make your life and your vehicle’s existence better.
And this miracle enhancement does not require you much of your time for installation. It can be put in your vehicle in just a few minutes and you do not have to take your car apart. Your car’s engine format also does not matter. For fuel injection engines, installation only requires detaching the air inlet hose from the throttle body and the air filter box, putting the Tornado inside the hose, replacing the hose back again and it’s done. For carburetor set-ups, it only needs putting the Tornado inside the air cleaner housing and the Tornado is ready to go.
Gear your vehicle with the Tornado Fuel Saver and experience better performance, improved fuel economy and increased horsepower.

John Hartley asked:
DIESELS are still gaining popularity in Europe, thanks to low gas mileage and good performance. The latest diesel cars can take on gasoline engined cars and come out on top!
All turbocharged diesels generate much more torque than gasoline engines, so you get better mid-range acceleration. In other words, from, say, 40-80 mph, a good diesel will see off a good gasoline engine car of the same apparent performance.
Jaguar has introduced a special version of a V-6 2.7 liter diesel that has been developed in Europe jointly by Ford and Peugeot. This is the most advanced diesel around at present, with the brand-new piezo-electric injector operation, the latest common rail injection system and twin turbochargers.
PIEZO-ELECTRIC INJECTORS
What are piezo-electric injectors? Cunning little ceramic devices, and when an electric current is applied they produce a pressure, and so can be used to force fuel into the cylinders. The thing is that they can be operated four times faster than other electro-mechanical injectors so the injector can be opened and closed incredibly quickly. Also, the amount of movement is very small, and you get less noise that you get from mechanical injectors.
Like I said, very cunning, and they all go with high pressure injection to give high power, low noise, emissions and gas mileage. It’s developments like these that mean we’ll have some diesels in Fast-Autos soon – but not a lot!
As a result, the fuel is injected at horrendously high pressures with incredible accuracy. The result? Masses of power, and almost no smoke, the weakness of old-fashioned oil burners, like the dreadful engines GM introduced about 20 years ago.
This new Jaguar S-Type diesel, develops 206 bhp so it lives up to the Jaguar tradition of high performance. Maximum torque is 320 lb ft (430 Nm) which is more than the 4.2 liter gasoline engine can manage without a turbocharger. Although performance is not sensational, it is definitely not what you’d expect from a diesel.
The Jag diesel will push the S-Type automatic up to 60 mph in about 8 seconds, and top speed is 140 mph. You’ll get the idea that Jag regards this as a sporty engine from the fact that it has a six-speed manual or automatic box – both are supplied by ZF. Of course, the most powerful S-Type is the S-Type R.
BMW HAS AN EVEN MORE POWERFUL DIESEL
BMW is also ready with a very powerful 3.0 liter diesel engine which turns out 272 bhp, which would be considered very nice thank you from most makers of 3.0 liter gasoline engines – Ford’s top version of its nice 3.0 liter V-6 develops 225 bhp. BMW uses twin-stage turbocharging to get this much power. In this system, one small turbocharger provides power at low speeds, and a bigger turbo is matched to high speed requirement. It is switched in when the speed and load increase sufficiently, and so can generate as much power as a gasoline engine of the same size.
If that is not enough power consider the latest news. Audi is racing diesel-powered cars at the Le Mans 24-hour race! These V-12 engines develop more than 600 bhp, and will challenge the best gasoline engined sports-racing cars.

Vikram Kumar asked:
So you have decided that a turbocharger is what your humdrum car needs, plus a few other aesthetic revisions. So you decide to look into a turbo kit. Unfortunately, you have no working knowledge of automotive technology beyond driving the car and filling it up with gasoline. Thus, you resort to guesswork and legwork in buying and installing a turbo kit, which can either lead to your car becoming a Frankenstein experiment or to your being wiser but poorer by not a few dollars. Here are a few considerations before purchasing a turbocharger for that most prized possession of the big boys – the car.
First, decide what you really want your car to do. There are many ways to turbo charge a car depending on your end goal, either you want it for show, or for speed, or for gas mileage, or for all three. Depending on your goal, a turbo kit can vary and turbocharger capacity can be adjusted, too. Second, when you have decided what you want out of your turbo kit, look into your car’s general condition. For those with delusions that their old cars can have a turbocharger installed, sorry to tell you that you have better drop the idea as fast as the speed of light itself. Cars with low-mileage engines that are in good condition with no excessive stresses imposed on them are the best candidates for a turbocharger. To determine this, you can have your car checked out in a reliable automotive shop, with emphasis on its engine parts like spark plugs and plug wires. A compression test is also highly recommended to test the rings, valves and seals. Remember that turbo charging your car can put stresses that it has never before experienced, so safety is always the golden rule. When the technician has given the go-signal, you can then proceed to purchasing the most appropriate turbo kit for your car.
At Vivid Racing, they have one of the most extensive lines of high-quality turbocharger and turbo kit products from prestigious manufacturers like Garrett, Blitz, Agency Power, APS, APEXi, Forced Performance, HKS, Greddy, Procharger, Forge, Perrin, Ralliart, Samco, and many others. From turbochargers and superchargers, to blow off valves and silicone hoses, to intercoolers and piping, Vivid Racing have it all and if you do not see what you need, you can always contact them and they will gladly get it for you. After all, they live by the principle that the customer comes first.
If you want a pre-configured turbo kit, Vivid Racing has many models to choose from to suit various car makes and models. Since their pre-configured turbo kits work with factory-installed engines and fuel systems, you will have no great difficulty installing your turbo kit. However, a turbocharger is a complex machine to deal with and installing it is serious and costly business, so it is better to have the turbo kit installed by expert technicians at Vivid Racing. With its state-of-the-art dyno machine, you are guaranteed that the turbo kit was installed properly (no leaks, correct wastegate operation, right boost control, and fuel management, among others) and you can see first-hand the improved performance of your car. This way, you get the double advantage of expert installation with safety precautions.

Few would debate that the Ford Taurus of past generations was about as unexciting and commonplace as a loaf of bread. But the new Taurus SHO (Super High Output) is attempting to shatter that dull image with the vibrancy of a very potent 365 horsepower engine. But this Ford offers more than just power. One of its main selling points is that this new Taurus has the power of a V8 and the fuel efficiency of a V6, in this case a 3.5 liter “ecoboost” V6. How did Ford manage to strike such an ideal compromise between horsepower and efficiency, and between excitement and utility? It certainly wasn’t due to new, innovative engineering, nor cutting-edge technology. They simply did what most car companies (including themselves!) did back in the late 1970s and early 1980s in response to the energy crisis: they added a turbocharger (two in the case of the new SHO) to an existing engine in their lineup.
Turbochargers allowed car companies to use eco-friendly, efficient, and small four-cylinder engines without completely sacrificing power. But as the energy crisis and obsession with efficiency and gas mileage waned in the early 1990s, naturally aspirated V6s and V8s (without turbos) made their triumphant return. Only a few manufacturers, such as Audi/VW, Volvo, and perhaps most ubiquitously, Saab, continued employing the proven formula of small turbocharged engines. And anyone familiar with Saabs knows of their legendary fuel efficiency—and it’s no coincidence that their cars used small turbocharged inline-fours almost exclusively.
Without a doubt, today the turbocharger has whooshed its way back into engine bays, and this time it seems that it will be here to stay. These new turbo engines are much more performance-oriented than their predecessors, and have found their way into sporty cars instead of pedestrian ones. Budget imports like Subaru’s WRX and Mitsubishi’s Lancer Evo, and domestics like the Dodge Neon SRT-4, all use turbos. The immense popularity and affordability of these cars, their reputation for thrilling performance, and movies like The Fast and the Furious, which abounds with turbocharged cars chirping their blow-off valves, have created a generation of car tuners lusting for that oversized snail lurking beneath the hood.
Above all, turbocharging in its various guises has become such a popular modification because it is by far the best bang-for-your-buck, assuming you know what you’re doing, of course. A large intercooler conspicuously showcased behind the front bumper, the “pshh” sound of a blow off valve between gear shifts, and the intoxicating, jet-like sound of a spooling turbo are all bonuses that tastefully alert any tuner to the fact that your car is packing a lot more than your average import.
Obviously, a turbo kit is a desirable upgrade for anyone looking to substantially augment their car’s power. But what exactly is a turbocharger, and what’s so special about it? At its most basic level, a turbocharger is simply an air pump/compressor driven by hot exhaust gases. On non-turbocharged engines, the exhaust gases from the engine run uninterrupted through an exhaust manifold(s) and through the rest of the exhaust system and out the tail pipe.
A turbocharged engine is a bit more complicated. On such an engine, instead of flowing straight through to the muffler, exhaust gases first travel through an exhaust manifold (turbo manifold), which collects and directs all of the exhaust gas into a large opening of the turbo that leads to the exhaust turbine (see picture below). From here, some of the gases flow out of the back side of the turbo, through a down pipe, and out the muffler like in a naturally aspirated engine. But the majority of the hot gases flow into the exhaust turbine, and in doing so the moving air spins the exhaust wheel (a small metal fan with many blades) inside of the exhaust turbine. This moving air causes the wheel to rotate very quickly—sometimes as high as 120,000 RPMs. The exhaust wheel sits on a shaft that rotates with it; on the other end of the shaft there is another wheel, known as the compressor wheel. This wheel spins at exactly the same rate as the one in the exhaust turbine, but it does nothing with the exhaust gases. Instead, ambient air is drawn through the turbocharger’s inlet pipe, where the rapidly moving compressor wheel literally compresses the air above atmospheric pressure, and then sends it out of the compressor’s outlet, where it then flows to the inlet of an intercooler en route to the engine’s throttle body and intake manifold.
The amount that this air is compressed varies widely depending on things like the stoutness of the engine’s internal parts and the fuel and engine management systems. This amount is measured in pounds per square inches, and is commonly known as “boost.” So low boost is around 5-10 psi (above atmospheric pressure), medium boost is around 10-15 psi, and high boost is 15-20+ psi. While this is a huge over-simplification, the more boost a certain engine produces, the more power is generated. In general, an increase of about 10 horsepower accompanies every 1 psi increase in boost. Right off the bat, it’s obvious that a lot of power can be made from boost—at only 5 psi the engine would still be producing roughly 50 more horsepower than if it did not have a turbocharger. Compare this power increase with what could be had by a set of expensive, difficult-to-install camshafts on a non-turbo engine, which might afford the engine 10-15 horsepower more, and it is obvious that turbocharging is the way to go for serious power increases.
