The main differences between the gasoline engine and the diesel engine are:
* A gasoline engine intakes a mixture of gas and air, compresses it and ignites the mixture with a spark. A diesel engine takes in just air, compresses it and then injects fuel into the compressed air. The heat of the compressed air lights the fuel spontaneously.
* A gasoline engine compresses at a ratio of 8:1 to 12:1, while a diesel engine compresses at a ratio of 14:1 to as high as 25:1. The higher compression ratio of the diesel engine leads to better efficiency.
* Gasoline engines generally use either carburetion, in which the air and fuel is mixed long before the air enters the cylinder, or port fuel injection, in which the fuel is injected just prior to the intake stroke (outside the cylinder). Diesel engines use direct fuel injection -- the diesel fuel is injected directly into the cylinder.

diesel engine does not has a spark plug while petrol engine has spark plug. both are though four stroke engines. petrol engine weigh less than diesel engine.
fuel burns in petrol engine with the help of spark plug, while in diesel engine fuel mixture is compressed to a great extent so that fuel burns because of compression.

there are many diifferences.. u plz visit some sites below.. one most important is that i am quoting!! is mean piston speed and production of energy and heat required to burn out the fuel.. Mean Piston Speed:l
ow speed diesels
~8 m/s for marine and electric power generation applications
medium speed diesels
~11 m/s for trains or trucks
high speed diesel
~14 m/s for automobile engines
medium speed petrol
~16 m/s for automobile engines
high speed petrol
~20 m/s for sport automobile engines or motorcycles

Petrol engine has spark plug and ignites fuel however diesel engine does not andfuel ignites due to pressure....Generally petrol engine is good and works good however deisel is high on maintanance and tears down easily
