Machinery-turbine integrated supercharger

Abstract

The invention relates to a machinery-turbine integrated supercharger which comprises a turbo-charging part, a mechanical supercharging part and a shared part, wherein the turbo-charging part comprises a turbine; the mechanical supercharging part comprises a belt pulley and a speed change gear; the shared part comprises an impeller, an engine, an air filter, an intercooler and a silencer; the air outlet of the air filter is communicated with the air inlet of an impeller shell into which the impeller is embedded; the air outlet of the impeller shell is communicated with an air intake manifold of the engine; the air discharge of the engine is communicated with the air inlet of a turbine shell into which the turbine is embedded; the crankshaft of the engine is used for driving the speed change gear through the belt pulley; and the output shaft of the speed change gear and the impeller are coaxially fixed with the turbine. The machinery-turbine integrated supercharger provided by the utility model fully takes the advantages of rapid low-speed response of a mechanical supercharger, no delay and good supercharging effect of a turbo-charger at a high speed, and fully utilizes the waste gas energy at the high speed to improve the output torque of the engine.

Description

technical field [0001] The invention relates to a gas supercharger for an engine, in particular to a mechanical and turbine integrated supercharger. Background technique [0002] The supercharger responds better at low speeds, but consumes the power of the engine itself at high speeds. Turbocharging is more efficient at high speeds but suffers from turbo lag at low speeds. Turbocharging uses engine exhaust gas as power to push the turbine to drive the impeller and pressurize the intake air. The advantage is that the energy is recovered from the exhaust gas that is about to be discharged, thereby saving energy to the greatest extent; the disadvantage is that due to the inertia of the turbine's own weight, when the exhaust gas is pushed, there is a rotation lag, which is manifested as turbo lag; the power of the supercharger comes from the flywheel or other The mechanical transmission part directly drives the impeller. The advantage is to avoid the hysteresis of the work, b...

The advantage is that the energy is recovered from the exhaust gas that is about to be discharged, thereby saving energy to the greatest extent; the disadvantage is that due to the inertia of the turbine's own weight, when the exhaust gas is pushed, there is a rotation lag, which is manifested as turbo lag; the power of the supercharger comes from the flywheel or other Mechanical transmission parts, directly drive the impeller

The advantage is to avoid the hysteresis of the work, but because the energy is extracted from the work of the engine that is about to be transmitted, it affects the power output of the engine to a certain extent compared with turbocharging
