Question

Why suoercharging is more beneficial in a ci engine compared to si engine ?

Answer 1

Akhil....

Answer:

Hence both can be used in both types of engines. SI engines may not require Supercharging, since of Gasoline fuel and spark ignition system. ... Turbocharging which uses exhaust gas require high pressure to run the turbine is possible mostly in CI due to high compression ratio. So it is more suitable for CI engines.

Answer 2

$\huge\purple{\boxed{\mathcal{Hello mate}}}$

So it is more suitable for CI engines. But Supercharging which directly draws power from engine, does not depend on exhaust gas pressure. Hence more suitable for SI engine since exhaust pressure is low due to low compression Ratio. Conclusion: Both Supercharging and Turbocharging can be used in both SI and CI engines
