Hi, Good Morning, I am Balaji, Today we discuss about IC Engines
00:06
Internal Combustion Engines classified into Two types
00:06
Spark Ignition (SI) Engines
00:07
Compression Ignition (CI) Engine
00:11
An IC engine is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit
00:17
Air Fuel Ratio (AFR)
00:19
AFR of the SI engines range 12:1 to 20:1
00:20
AFR of the CI engines range 18:1 to 70:1
00:25
In summary, the use of ethanol in SI engines has the advantage of reducing most regulated emissions
