Question:medium

The compression ratios for diesel engines lie in the range of :

Show Hint

Diesel engines are compression-ignition engines and require high compression ratios (\( 15 \) to \( 20 \)) to generate sufficient heat to auto-ignite the injected fuel.
In contrast, petrol engines operate at lower ratios (\( 6 \) to \( 10 \)) to avoid knocking.
