Diesel Engine

 The Diesel Engine invented by Diesel, Diesel Engine is  IC Engine in which Ignition fuel takes inside  Engine Cylinder. The temperature of the air in the cylinder due to mechanical compression So called a compression-ignition engine (CI engine). In Petrol Engine Spark plug is used, In Diesel Engines Fuel Injector Used.

 

 In Diesel Combustion Chamber Compressing only air, or air plus residual combustion gases from the exhaust System this also called exhaust gas recirculation  (EGR). This increases the air temperature inside the cylinder so that cut fuel into small parts then  diesel fuel injected into the combustion chamber ignites.

 

THE DIESEL ENGINE IS INTERNAL COMBUSTION ENGINE. IT MAINLY CONSITS OF 4 STROKES THEY ARE 1)SUCTION or INTAKE, 2)COMPESSION 3)POWER or EXPANSION, 4)EXHAUST

 

The size or cubic capacity (cc) of  Petrol or diesel engine is measured in cubic centimetres (cc).The amount of air and fuel that can be pushed through the cylinders in the Petrol or Diesel Engine. Bigger the capacity Bigger cc, Fuel efficiency may be defined as the amount of energy released per unit mass of the fuel.The highest possible efficiency for a diesel engine is 75%, A fuel that will be suitable for automobiles should have a high calorific value to get better Efficiency. The fuel is mixed with air inside the cylinder in Diesel Engine but In Petrol Air and the fuel are mixed in a carburettor, In Diesel Ignition with the help of the hot, compressed air in Combustion Chamber, High compression ratio Diesel But In Petrol low Compression Ratio. Diesel Engines used in heavy vehicles such as trucks and buses, Petrol Engine  used in two wheeler and light vehicles, High initial and maintenance costs compare to petrol Vehicles
