Question

Petrol Engines are best suited for heavy vehicles such as lorries, trucks and railway engines.

• A. True
• B. False

Answer 1

The correct option is B False

False
Diesel engines are bigger, heavier built due to the higher compression ratio and higher vibration levels. That also makes them more fit for heavier vehicles where the weight and noise/vibration of the engine is less of a problem because the bigger vehicle has more mass to damp/spread these vibrations. Diesel engines produce more torque (you can say the pushing force) than petrol ones, which is required for heavy vehicles.
