The internal combustion engine is of high
importance in industrial civilization. It works to burn the fuel inside the
engine and convert the generated energy into the motion. The fuel used is
either gas or diesel. There are different types of internal combustion engine
available in the market, but they have the same basic components and work on
the same basic principle.
Piston
A piston is the moving component that is
contained by a cylinder and is made gas-tight by piston rings. Cummins Piston rings are used to identify a two stroke or four stroke engines. It comprises of
compression ring, wiper ring and oil ring. High quality die- or gravity-cast
aluminum alloy is used in Piston manufacturing. It is light weight, has good
structural integrity and reduces overall mass and force.
Piston reciprocates up and down in a
cylinder, compressing an air/fuel mixture and then exerting force from the
controlled explosion of that mixture downward onto the connecting rod and
crankshaft.
Connecting Rod
High quality steel alloy is used in
manufacturing cummins connecting rods which helps in bearing heavy loads without getting twisted, snapped or
bend.
The connecting rod is attached to the bottom
of the piston by a mechanism that allows is to rotate in a flat plane. Its other
end is attached to the crankshaft. When the piston goes down, the connecting
rod moves in a motion that forces the crankshaft to turn.
Crankshaft
Cummins Crankshaft consists of a rotating
shaft with several "crank pins" placed at different angles. Crank
pins are so placed that its axis is offset from the axis of the rotating shaft.
The crankshaft is connected to the
pistons by the connecting rods, the force generated by the burning fuel air
mixture is transferred to the crankshaft and converted to rotary motion which is
transferred in the form of torque to clutch and thereby gearbox and
wheels.
Valves
Valves are so scientifically designed that
they provide maximum strength and durability.
Valves function to control the entry of fuel
and air into the combustion chamber and exit of exhaust gases from the
combustion chamber. These functions should be carefully timed to ensure that
the entry of the fuel, the burning of the fuel, the movement of the piston and
the exit of the exhaust all happen in the right order.
