Combustion in Spark Ignition (SI) Engines | IC Engines | Thermodynamics
In SI engines the combustion chambers have homogeneous air fuel mixture that is compressed after induction stroke. Towards the end of the compression stroke the spark plug gives out high temperature spark to initiate the ignition process. The spark may have temperature as high as 10,000°C. The combustion spreads from around the spark plug and spreads rapidly across the combustible [...]
