Background

The traditional turbocharger has the defects of insufficient low rotating speed torque, poor transient response, acceleration smoke generation, difficult cold start and the like. The reason for these problems is that when a turbocharger is matched with an internal combustion engine, the turbocharger and the vane-type supercharger can only have optimum matching performance within a certain operating range due to the difference in the gas flow characteristics of the piston engine and the vane-type supercharger. The supercharger is not mechanically connected with the engine but connected with air intake and exhaust, so that in variable working conditions, pressure wave transmission needs a certain time, and a supercharger rotor has a time lag problem, so that the oil supply amount of the engine and the air amount provided by the supercharger are not synchronous instantaneously. The adjustable variable-section turbocharger electric control actuator can effectively overcome the defect, the electric control adjustable turbine pressure increase can be matched with the working condition of an engine to change the size of the flow section area of the turbine in real time, and the optimal matching of the engine and the supercharger in the full working condition range is realized, so that the comprehensive optimization of the performance of the engine is achieved. Can guarantee that the engine has higher boost pressure when low speed, make the fuel burning abundant, improve effective torque, reduce harmful gas and discharge, can guarantee again that the engine is unlikely to too high near rated operating point boost pressure to avoid too high mechanical pressure of engine and turbo charger to surpass, effectively avoid the detonation, transient response when also can increase acceleration.
