DIESEL ENGINES:
             It is large in size and more noice,it has low fuel efficiency.But it is also widely using as the petrol engines.The pure diesel is used as the fuel in a diesel engine and there is no mixing of air or another.The fuel injector is used to spray the diesel into the cylinder.The fuelinjector can make the diesel into small particles.So a small compression can burn this diesel.The compression is given by the piston.It's piston is different from the petrol engine's.The piston is called "difflector piston".It's head will created in a special shape to a particular use(It is used to difflect the burned diesel into two direction).If the head is flat the burned fuel will rotates like a cycle.so the difflector piston is used to difflect this burned fuel in the outlet valve.This is the working principle of a diesel engine.

ADVANTAGES:
          >The fuel is comparatively less cost.
          >Used for heavy vehicles
          >It can offer more power
