Fuel inject (spray) by a nozzle in combustion chamber.

Inlet valve for air intake & exhaust valve for exhaust valve. Therefore we find two valve & one injector in a diesel engine.

Valve arrangement merely depends on no of cylinders, Each cylinder can use two valves (one exhaust one intake) or Each cylinder can use four valves 2 intake and 2 exhaust.

As per R.S. KHURMI, Diesel engines have three valves i.e. Inlet valve, exhaust valve, and fuel injector valve.

But I am also not satisfied for this.

In diesel engine either 2 valve or 4 valve are present.

But in some case solenoid (DICOR) is treated as valve so total 3 or 5 valve could be said.

I have studied diesel engines two valves. One is inlet valve other.

One is exhaust valve. The fuel injector is a fuel in a combustion chamber.

I think two valve is the right answer, but in RS Khurmi fuel injector is considered as a valve. But exactly it is injector, not a valve.

I know only 2 valves in engine but according to R. S KURMI there is three valves. The third one is fuel injector valve.

I have studied diesel engine has two valves, fuel injector is a port that delivers only fuel in combustion chamber.

Two valves (inlet & exhaust), but injection is by port(injector nozzle).

So, diesel engine has two valves.

@All.

I have a truck in my home and everytime I saw either two valves or four valves. But never three valves.
