So as to improve burning capacity for work.Therefore under the conditions of current technology, turbocharger is only engine to be made to work
Increase the mechanical device of power output in the case that efficiency is constant.
Usually described turbo charging installation is exactly a kind of booster (air compressor/compressor) in fact, passes through compression
Air increases the air inflow of engine, in general, turbocharging be all using the waste gas inertia impulsive force of engine discharge come
The turbine in turbine room is promoted, turbine drives coaxial impeller, the air that impeller force feed is sent by air cleaner pipeline, made again
Supercharging enter cylinder.When engine speed is speeded, the waste gas velocity of discharge is also synchronously speeded with secondary speed, and impeller just compresses more
More air enters cylinder, and the pressure and density of air increase more fuel that can burn, corresponding to increase fuel quantity and adjustment
The rotating speed of engine once, it is possible to increase the power output of engine.
Turbo charge system is mainly made up of turbine and booster.It is the air inlet and the exhaust pipe of engine of turbine first
It is connected.Then the air inlet of booster is connected with air cleaner pipeline, and exhaust outlet is connected on engine air inlet tube, last turbine
It is attached separately to impeller in turbine room and booster, the two coaxial rigid connection.
Turbocharged engine lose throttle (refer to " accelerator releasing pedal " or " wheel end torque demand be 0 ") etc. operating mode
When, because after booster, the pressure of engine throttle this section of pipeline in front of the door is big and flow is small, when reaching stall margin (booster
Under different operating rotating speed, flow can keep the limit boundary line of air-flow not loss of stability when reducing) when, relief valve, which is opened, makes pressure
The quick removal of power, and there is energy loss in this process, cause the waste of energy.
