TURBO CHARGER ASSEMBLY

The turbo charger is an air pump installed on the intake manifold. It enhances power and increases torque power of
engine to increase the fuel consumption rate. The engine without turbo charger cannot get as much power output as it
inducts air by the means of vacuum being generated from descending strokes of the piston. Therefore, by installing the
turbo charger on the intake manifold, it supplies great amounts of air to the cylinder increasing the volume efficiency
and, subsequently, enhances output power.
Also, as the engine's power enhances, it increases the torque power and improves the fuel consumption rate. The
regular turbo charger operates by utilizing the pressure from the exhaust gas and the other, called Super Charger,
operates by utilizing power from the engine. When the turbo charger is installed, weight of the engine increases by 10
to 15 % whereas the output power increases by 35 to 45 %.

Operating Principle of Turbo Charger

The turbo charger has one shaft where at each ends are in-
stalled with two turbines having different angles to connect
one end of housing to the intake manifold and the other end to
Turbine
the exhaust manifold. As the turbine, at exhaust end, is ro-
tated by exhaust gas pressure the impeller, at intake end,
gets rotated to send air around center of the impeller, being
circumferentially accelerated by the centrifugal force, into the
diffuser.
Exhaust The air, which has been introduced to the diffuser having a
passage with big surface, transforms its speed energy into
the pressure energy while being supplied to the cylinder im-
proving the volume efficiency. Also, the exhaust efficiency
improves as the exhaust turbine rotates. The turbo charger is
Y220_04008
often referred to as the exhaust turbine turbo charger.
Diffuser: With the meaning of spreading out it is a device that
transforms fluid's speed energy into the pressure energy by
enlarging the fluid's passage to slow down the flow.
