Why do most cars use gasoline instead of diesel?

then why do most cars have gasoline engines. Diesel engines have never really caught on in passenger cars in the United States. During the late nineties seventies, diesel engines and passenger cars did see a surgeon sales because of the OPEC oil embargo. Over half a million diesel cars were sold in the US, but that is the only significant penetration that diesel engines have made in the marketplace. Even though they are more efficient, there are historical problems that

have held diesel engines back. First, diesel engines have much higher compression ratios. The compression ratio of twenty to one is typical for a diesel versus eight to one for a typical gasoline engine. That compression ratio makes diesel engines heavier than an equivalent gasoline engine. Second, diesel engines also tend to be more expensive. Third, diesel engines, because of the weight and the compression ratio, tend to have lower

maximum rpm rages than gasoline engines. This makes diesel engines high torque rather than high horsepower, and that tends to make diesel engines slower in terms of acceleration. Fourth, diesel engines tend to produce more smoke, and they tend to smell funny. Although modern designs and modern fuels have greatly reduced the problem, the perception persists. Fifth diesel engines can be harder to start in cold weather, and if they contain globe plugs, diesel engines can require you to wait

before starting the engines so the globe plugs can heat up. Sixth, diesel engines tend to be noisier and tend to vibrate more, although modern engine designs are fixing these problems as well. Seventh, diesel fuel is less readily available than gasoline, especially in urban areas. One or two of these disadvantages might be okay, but a group of disadvantages this large is a big deterrent for lots of people. The two things working in favor of diesel engines are better fuel economy and longer

engine life. Both of these advantages mean that over the life of the engine, you will tend to save money with a diesel. However, you also have to take the initial high cost of the engine into account. You have to own and operate a diesel engine for a fairly long time before the fuel economy overcomes the increased purchase price of the engine. The equation works great and a big diesel track or trailer rig that's running four hundred or five hundred miles every day, but it's not nearly

so beneficial in a typical passenger car. Many of the new diesel engine designs using advanced computer control are eliminating many of these disadvantages. Smoke, noise, vibration, and costs are all declining. In the future, we're likely to see more diesel engines on the road. For more on this and thousands of other topics.
