1. TURBOCHARGERS IN PETROL
AND DIESEL-DRIVEN CARS

2. The applications of turbochargers are manifold. Besides its use in aircraft,
motorcycles and ships, turbochargers also feature heavily in automobiles.
These can be driven either by petrol or diesel. How then do the turbochargers
in these cars differ? Below, we explore 3 key differences.

3. SIZE
Turbochargers in diesel engines tend to be sturdier
and larger in size, owing to the high combustion
pressures caused by the atomisation of diesel fuel
as it enters the combustion chamber. Furthermore,
diesel fuel burns at very low temperatures, thereby
generating a lot more exhaust gases than petrol
engines do. The engine has to be fitted with a larger
turbine to accommodate the intake of exhaust
gases, hence adding to the size of the turbocharger.

4. ENGINE REVOLUTIONS PER MINUTE (RPM)
Given the size of turbochargers in diesel-
driven cars, the RPM of turbochargers tend to
be lower than that of petrol-driven cars.
Additionally, petrol burns at high
temperatures, so a higher RPM is needed in
order to drive the car.

5. COOLING SYSTEMS
As a large amount of heat is generated in
petrol-powered cars, turbochargers in these
automobiles tend to be fitted with better
cooling systems, so as to prevent the engine
from overheating.
