Background

The turbocharger includes a turbine housing and a bearing housing that are integrally coupled to each other. The rotating shaft is connected to a turbine wheel provided inside a turbine housing so as to be integrally rotatable, and is supported by the bearing housing.

The existing turbocharger utilizes the inertia impulse force of the exhaust gas discharged by an engine to push a turbine in a turbine chamber, the turbine drives a coaxial impeller, and the impeller pumps the air sent by an air filter pipeline to pressurize the air to enter an air cylinder. When the rotating speed of the engine is increased, the exhaust gas exhaust speed and the rotating speed of the turbine are also increased synchronously, the impeller compresses more air to enter the air cylinder, the pressure and the density of the air are increased, more fuel can be combusted, and the output power of the engine can be increased by correspondingly increasing the fuel quantity and adjusting the rotating speed of the engine.

Through long-term research by the inventor, the temperature of the exhaust manifold can reach 1000 ℃, people rarely utilize the heat of the exhaust manifold, and great waste is caused.
