Why do we use diesal engine for heavy machinery and not petrol?
Answer Posted / mohankumar
The higher compression ratio is helpful in raising fuel
efficiency. Diesel engines are much more efficient than
petrol engines when at low power and at engine idle. Diesel
engines, unlike the petrol engine, lack a butterfly valve
(throttle) in the inlet system, which closes at idle. This
creates parasitic loss and destruction of availability of
the incoming air, reducing the efficiency of
petrol/gasoline engines at idle. This mechanism makes the
diesel engine an attractive choice for many. Diesel engines
are left idle for many hours or sometimes days in many
applications, such as marine, agriculture, and railways.
The engines are more efficient when compared to petrol
engines of the same power. They consume significantly lower
fuel and offer better mileage.
