There was a time a few years ago when everyone wanted to jump on the bandwagon for diesel engine cars. Diesel was cheap, the cars ran just as good and people liked them. Until the manufacturers of diesel realized they could make some extra money by changing the price of the fuel needed in order to run these types of engines. Down went the popularity of diesel engines in cars.
But diesel engines still exist. They often power the bigger vehicles, like school buses, semi-trucks and delivery trucks that are on the road today. Why are these vehicles still powered by diesel when it costs more to power the car? Because they are built differently and works better with heavier vehicles.
There are a lot of differences between the diesel motors and the regular engine of a car that is powered by gasoline. The biggest difference is how the car starts. A diesel engine compresses air first and then heats up, and then the fuel (diesel) ignites and powers the engine. The other engines has the fuel mixed with the air and then get compressed by the piston chambers, causing it to fire and power the car.
