Problems solved by technology
Atmospheric pressure changes with altitude or climatic conditions, affecting the pressure difference between boost and atmosphere, affecting the ability to control boost
In addition, using the wastegate valve to control the boost and the cycle of using the boost to drive the wastegate means that there is a close internal relationship between controlling the boost and using the boost to drive the boost-based wastegate, so that the wastegate The operation of the through valve cannot be predicted under ideal conditions

The invention discloses a turbocharger control mechanism for a piston engine, and a control method of the turbocharger control mechanism for the piston engine. The turbocharger control mechanism for the piston engine comprises an engine body and a waste gas turbocharger; and an inlet manifold and an exhaust manifold are arranged on the engine body. The turbocharger control mechanism for the pistonengine is characterized in that a pressure sensor for sensing inlet pressure is arranged on the inlet manifold; the pressure sensor is connected with an ECU controller and outputs a signal to the ECUcontroller; and the ECU controller controls the opening of a waste gas bypass valve arranged in an exhaust pipeline through a stepping motor so as to control the quantity of waste gas entering the waste gas turbocharger, so that adjustment and control on the inlet pressure are achieved. With the adoption of the turbocharger control mechanism for the piston engine, and the control method of the turbocharger control mechanism for the piston engine, the integral structure is simplified, the adjustment accuracy is high, the response is fast, the inlet turbocharging pressure fluctuation is small,and the turbocharger control mechanism for the piston engine and the control method of the turbocharger control mechanism for the piston engine have the relatively good application prospect.
Description
technical field [0001] The invention belongs to the technical field of engines, and more specifically relates to a turbocharger control mechanism for a piston engine and a control method thereof. Background technique [0002] A supercharger is an air compressor that increases the intake air volume by compressing air. It is widely used in automobile engines and aviation piston engines to improve the combustion efficiency and liter power of the engine, and improve the high-altitude performance of the aviation engine. [0003] The types of superchargers include exhaust gas turbocharging, supercharging, and a hybrid of exhaust turbocharging and supercharging. At present, the most widely used exhaust gas turbocharging is called a turbocharger. The turbocharger is mainly composed of three parts: the turbine, the compressor and the control mechanism. The turbine and the compressor are coaxial blade mechanisms. Its working principle is: high-temperature and high-pressure exhaust ga...
