The world's Largest Turbo Manufacturer. |
| A turbocharger is really a hot air pump forcing more air into the
engine. |
an i/c engine runs more efficiently with more air..like a fire will burn more
efficiently with more oxygen |
| ...what is the point of a turbo? |
improve engine performance, reduce fuel consumption
and lower emissions. |
The turbo is mounted between the exht manifold
and the exhaust pipe
|
| Think of the turbo in 2 parts |
1. The Turbine - this is the exhaust side - exhaust
ges are directed onto the turbine wheel making it spin |
| 2. The compressor - this is the side which compresses air,
forcing it into the engine (intake manifold) The compressor wheel is connected by a shaft
to the turbine wheel. |
| other important features of the turbo are |
| It spins ft (up to 240,000 RPM) so it's supply of oil is
crucial |
it is subject to very high temperature - 900 degrees C |
|

Early wtegate t'bo
with vacuum actuator |
h a limited range of effectiveness, suffers from 'turbo-lag' |
| Modern variable nozzle turbo VNT |
h variable nozzle which makes it more responsive across a wider range of
engine speeds from low to high.
VNT h its own ECU giving finer control |
| Why fit a turbocharger to an engine? |
| A turbo improves the response of the engine |
| A turbo improves the fuel economy of the engine |
| A turbo improves engine braking |
| A turbo allows the use of a smaller engine unit to achieve a
given power output |
