Parts of the Diesel Engine
The piston starts up from the bottom dead centre and the air is compressed into the cylinder.
Just before the piston reaches top dead centre, an injector sprays fuel into the chamber
While the exhaust valve is open the piston returns to the top dead centre, forcing exhaust gases out.
The intake valve opens the air enters and the pistons start to move down
Differences between Petrol and Diesel engines.
No spark plug is needed
Higher preassure in the combustion chamber.
Sales of diesel vehicles nowadays.
More resistant pieces into the cylinder.
Petrol: 1.4e+6 Pa
Diesel: 2.8e+6 Pa
up to 3%
up to 53%
