Diesel engines and well known gas

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


engines.


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.
