• Increase in compression ratio in compression ignition engine increases delay period.
• In compression ignition engine, delay period increases with decrease in advance angle.
• In spark ignition engine, pre-ignition decreases the tendency of detonation in the engines.
• Flame speed in spark ignition engine is higher when the equivalence ratio,Ø less than one.
• The degree of turbulence decreases directly with the piston speed.
