Diesel Engines And Well Known Gas

In passenger cars, the diesel engine has never really

caught on. During the middle to late 70s, diesel

engines in passenger cars did notice a surge in

sales due to the OPEC oil embargo, although that is

the only real significant penetration that diesel

engines have made in the market.

Although diesel engines are more efficient, there

are eight historical problems that may have held

them back.

1. Due to the higher compression ratios,

diesel engines tend be heavier than the equivalent

gasoline engine.

2. Diesel vehicles and diesel engines tend to

be more expensive than gas.

3. Because of their weight and compression

ratio, diesel engines tend to have lower RPM ranges

than gas engines. This gives diesel engines more

torque rather than higher horsepower, and this tends

to make diesel vehicles slower in terms of acceleration.

4. Diesel engines have to be fuel injected,

and in the past fuel injection was very expensive

and less reliable.

5. Diesel engines tend to produce more

smoke and smell very funny when compared to gasoline


6. They are harder to start in cold weather

and if they contain glow plugs, the diesel engines

may require you to wait before you start the

engine so that the glow plugs can heat up.

7. Diesel engines are much noisier than

gas engines and tend to vibrate quite a bit.

8. Diesel fuel is less available than gas.

Although one or two of these disadvantages would be

acceptable, a group of them is a big turn away for

many people.

Even though the list above are reasons in the past

as to why diesel never really took off, you can

expect these reasons to get corrected and improved

in the future, meaning that you will see more and

more diesel vehicles on the road.
