both gasoline and diesel engines are internal combustion engines. Both perform the function of converting chemical energy into mechanical energy using a fuel injection system.

Small chemical explosions occur in the combustion chambers of both engines, but the way they take place is different for each engine.

The major difference between the engines is that diesel gas engines in Toronto have a spark plug that produces a spark to ignite the air/fuel mixture in the combustion chamber, whereas diesel engines do not have the spark plug and the fuel is ignited by compressed air instead.

Here are a few more differences byways of their functioning.

Gasoline fuel injection system
• In a gasoline engine, the fuel injection system injects a homogenous mixture of fuel and air into the combustion chamber through the fuel injector
• The mixture is then compressed by the piston which moves up and down in the chamber to pressurize the air and fuel mixture
• The pressurized mixture is then ignited by the spark that is produced by the spark plug
• In gasoline engines, the fuel is not injected with high pressure because the fuel has to mix with air in the fuel valve before getting injected into the chamber. The pressure with which the mixture is injected by the fuel injector into the chamber will be 10 psi to 60 psi
