A Compression Ignition (CI) engine is an internal combustion engine in which the fuel ignites automatically due to the high temperature created by compressing air inside the cylinder. Unlike spark ignition engines that require a spark plug to ignite the fuel-air mixture, CI engines rely solely on high compression pressure and temperature to start combustion. These engines are commonly known […]

A spark ignition engine (SI engine) is a type of internal combustion engine where the air–fuel mixture is ignited by a spark produced by a spark plug. These engines typically use petrol (gasoline) as fuel and operate on the Otto cycle, which is widely used in light-duty vehicles and small machines. Spark ignition engines play a crucial role in modern transportation
