Turbo Operating System Principles
|
|
In
exhaust gas turbocharging, some of the exhaust gas energy, which
woul normally go to waste, is used to drive a turbine wheel
and shaft. On the same shaft as the turbine wheel sits a compressor
wheel, which draws in ambient air, compresses it and then supplies
it to the engine.
What are some of the advantages of exhaust gas turbocharging?
- Compared with a naturally aspirated engine of identical power,
the fuel consumption of a turbo engine is lower, as some of
the normally wasted exhaust energy contributes to the engines
efficiency.
- The engine's torque characteristic can be improved. Therefore,
climbing a hill requires fewer gear changes and speed loss is
lower
- The power-to-weight ratio, i.e. horsepower (power output)/lbs.(engine
weight), of the exhaust gas turbocharged engine is much better
than that of the naturally aspirated engine. |
