A four stroke cycle engine develops twice the power as that of a two stroke cycle engine.

For the same power developed, a four stroke cycle engine is lighter, less bulky and occupies less floor area.

The petrol engines are costly than diesel engines.

Compression ratio for petrol engines varies from 6 to 10.

Higher compression ratio in diesel engines results in higher pressures.

Petrol engines work on Otto cycle.
