TYPES OF FUELS

 The fuel is the essential requirement of an engine to produce combustion.Many engines use different types of fuels,but the commonly used fuels in IC engines are petrol and diesel,rarely auto gases and CNG are used as fuel types.The fuel is ignited to produce combustion, and.at the time of combustion the compression ratio must be high to get maximum efficiency.The fuel inlet is controlled by the inlet valve and the exhaust is controlled by the outlet valve.Both the valves are controlled by timing section.
                       Engines which use petrol as a fuel has less maintenance while diesel has a greater maintenance. Petrol has less maintenance comparing with diesel.
                       Another type is the CNG and AUTO GAS fuels.Auto gases have higher efficiency than petrol and diesel engines in mileage,but there is a minimum factor of safety as the gases may leak due to some malfunctions.Also the engines don't go up to their expected speed when auto gas is used as a fuel.
                        All the fuel types have different types of ignition for combustion. Like wise the petrol engines have spark ignition and diesel engines have compression ignition.Both compression ignition and spark ignition play a important role in IGNITION SYSTEMS OF AUTOMOBILES(IC ENGINES) .
