Greetings:
What is the difference between a gasoline engine and a diesel
engine?
In a diesel engine there is no spark plug. Instead, diesel fuel is
injected into the cylinder,
and the heat and pressure of the compression stroke cause the fuel to
ignite. Diesel fuel
has a higher energy density than gasoline, so a diesel engine gets
better mileage.
The excellent web site on How Stuff Works goes into the details
of both types of engines
with super animated drawings that are much better than my trying to
describe the engines
operation in words. Start with the engine web site, it describes
different types of gasoline
engines and leads into the second web site that describes Diesel
operation:
