Inlet valve, exhaust valve and relief valve.

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.

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.

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

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.

@All.

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

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

So, diesel engine has two valves.
