I will explain on a 1 cylinder engine. This makes it easier to under stand. Inside the cylinder is a piston that moves up and down tight to the side walls of the cylinder. Connected to the bottom of the piston is a rod. The rod connects to a shaft called a crankshaft at the bottom of the engine. The crankshaft is connected to the transmission. When the piston is moved downward it turns the crankshaft, also fuel is either pulled in through a carbuerator (cars pre-1986) or pumped in through electronic fuel injection system (callel EFI) above the piston. The crankshaft is still turning and momentum pushes thepiston back up. The fuel and air above the piston are compressed (at least 120psi for gasoline, 500psi for diesel I will explain later.) In a gasoline engine the compressed mixture is ignited by a spark plug located at the top of the cylinder, forcing the piston down and continuing the cycle. In a diesel engine the diesel/air mix is compressed more to create heat. The heat becomes so intense that it ignites and forces the piston downward.

Why do you need to bleed a diesel?
Diesel engines work in a different way to petrol in that they work on pressure to ignite warm diesel as opposed to petrol engines which have spark plugs. in order to work, there can be no air, air wont ignite!!
What are the disadvantages of petrol engines?
petrol does not last forever
What is the indicated power formula for four stroke petrol engines?
Work=Power x Time
What are the defferences between dessel and petrol engine?
Petrol & Gas engines are spark ignited engines where as diesel engines are compression ignited engines. Petrol engines works with explosion of fuel air mixture due to spark from spark plug inside the cylinder. Diesel engines works with combustion of fuel air mixture due to compression, compressed mixture attains a very high temperature which exceeds the flash point of diesel and starts burning inside the cylinder and the hot gases after burning of fuel misture exerts force on piston which makes the diesel engines work. Diesel engines are highly efficient than petrol engines.
How petrol engines function?
WHAT ARE THE BASIC PARTS OF PETROL ENGINE? HOW DOES PETROL ENGINE WORKS?
What is the symbol of glowplug on a petrol engine for?
it could be for the spark plug, petrol engines dont need glow plugs, diesel engines do
What is the difference between petrol and diesel engines?
diesel engines doesn't use spark plug but uses heater plug.petrol engines produces more torque than petrol engines but petrol engines produces more acceleration than diesel engines.petrol engine is faster to be heated than diesel engine.
Do all Ford Mondeos have Zetec engines?
No, Mk1 and Mk2 petrol models had Zetec (belt driven)engines. Mk3 petrol models have Duratec (chain driven) engines. All diesel models have Duratorc engines
Why the turbocharger is not use for petrol engine?
Turbochargers are used on some petrol or gasoline engines.
What is the use of petrol in a vehicle?
petrol ( or gas to the Americans) powers the combustion engines of vehicles.
Is the petrol engine is costly thab diesel engine?
No, diesel engines cost more to build than petrol engines. They are built much heavier.
How did the first automobile work?
Some used steam-powered engines, others used early petrol or gas engines. Some even used battery-powered electric motors.
