Engine valves play a critical role in the performance of all internal combustion engines. They regulate, control and direct the proper amount of air and fuel inside the engine’s combustion chamber for ignition to occur.
The most common type of diesel engine valve is the poppet-type. It has a slim stem that leads to a flat-faced piece of metal, which is the head. It looks similar to a plunger or the shaft of a trumpet. Each poppet valve rests in a circular hole on top of the combustion chamber. The valve seat is what creates a tight seal between the valve and its surface — and the valve spring keeps the component closed by pushing against a retainer.
