In a Diesel Injector, there is a needle valve to expel the Diesel fuel in the combustion chamber. Taking into account the needle valve, the diesel engine has three valves.
1 - Inlet valve
2 - Exhaust valve
And 3. Injector.

@All.

There are Only two valves in a diesel engine. The fuel injector is not a valve.

Injection port can be considered as valve because Valve is a thing that controls the amount of flow by either stopping the way or opening the way.

I think this is the answer. Correct me if I am wrong.

Only two valve in diesel engine.

Three valve is used only in pre-requirement of diesel engine.

We can consider the inlet and outlet as a valve but fuel injector as a port.

I think FI cannot be termed as valve because diesel engine has multi point injection system for fine atomization in order to get nearly homogeneous mixture inside cylinder. This can be done through very small ports and also through number of ports at different locations. So, diesel engines have two valves.

Any modifications are welcomed.

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.
