Rev counter for diesel engines
Although most petrol-engined cars and lorries have a rev counter as standard, that is by no means the case in diesel-engined motor vehicles. The reason for this is that, since a diesel engine has no contact breaker, it is not so easy to derive pulses to drive a rev counter. There are, none the less, several possibilities of adding a rev counter if so desired.
