Description
Technical field
The present invention relates to automobile production manufacture fields, specially a kind of for the turbo blade of automobile manufacture and its processing side
Method.
Background technique
Turbo charged main function is exactly to improve air input of engine by air, to improve the power and torque of engine, is allowed
Car is energeticallyer.After one engine loads onto turbocharger, maximum power with without booster when compared with can increase
Add 40% even higher.Also mean that same one engine can export bigger function after pressurization in this way
Rate.For by our the most common 1.8T turbocharged engines, after pressurization, power can achieve 2.4L engine
Level, but fuel consumption but unlike 1.8L engine height how much, in another level for be exactly improve fuel oil warp
Ji property and reduction exhaust emissions.
Engine mechanically drives mechanical supercharger to be pressurized, referred to as engine driven supercharging.When engine is using mechanical
When pressurization, booster is usually driven by gear by engine crankshaft.Booster generally uses centrifugal or Root's compressor, a
It is other to use spiral lobe compressor.In recent years, also start external using novel mechanical turbocharger.Because of driving pressure
Mechanism of qi consumes the certain output power of engine, so the thermal efficiency of mechanically-sapercharged engine is not necessarily improved, sometimes
It is also lower than naturally aspirated engine instead.
The blade assembly of existing turbocharger is metal, and the turbine flabellum of metal is heavier due to being self-possessed,
It often needs just push it rotation by powerful air-flow in driving blade in the operational process of automobile, in turbine section
