|what is the advantage og having an overhead valve engie?|
|As the name implies, OverHead Valve engines (OHV) have the valves located above the combustion chamber, in the roof of the cylinder head.|
The OverHead Valve layout permits smoother fuel mixture intake, plus quicker and more complete exhaust. This increased combustion efficiency, in turn, enables a higher compression ratio to be used. In this way it is possible to obtain a greater power output and to avoid the build-up of carbon.
The OHV-design gives also an excellent thermal balance, which contributes to reduced cylinder distortion, a decease in oil consumption and an increase in engine service life.
