What is the difference between a SI engine and a CI engine?
An SI engine ignites the fuel with a spark (SI = Spark Ignition) whereas the CI engine ignites the fuel with heat generated from compression (CI = compression ignition)
How do you reduce the knocking in SI engine and CI engine?
Adjust timing and/or quality of fuel
What is peak pressure in si engine?
30-40 bar peak pressure
Why si engines are quantity governed engines and ci engines are quality govrned?
All engine are whether CI or SI are quantity governed. what is quality governed?? You have discovered it or wht??
What are the supercharging limits for si engine and ci engine?
Limit of supercharging in si engine (1) knocking tendency in si engine increases with increase with temp pressure density of charge , mixture strength (2) compression ratio of engine needs reduced with supercharged engine but the reduced compression ratio reduce the power output output & thermal efficiency of engine with increase in s.f.c WHEREAS Limit of supercharging in CI Engines are mainly due to the thermal stresses and increased gas loading. Due to this, the heat generation and heat transfer increases and there is a greater tendency to bum the piston crown and the seat and the edges of exhaust valve. Increasing the valve overlap in supercharged engines solved this problem.
Full form of SI engine?
SI stands for Spark Ignition. eg. Petrol Engine.
What is the difference between a SI engine and a CI engine?

What is SI engine and CI engine?
An SI engine is a spark ignition engine. A CI engine is a compression ignition engine. SI engines use spark plugs to ignite fuel in the combustion chamber. CI engines use compression in the combustion chamber to ignite the fuel.
