Engine electric supercharger structure with bypass valve

Abstract

The invention discloses an engine electric supercharger structure with a bypass valve. The engine electric supercharger structure with the bypass valve comprises a straight pipeline; a gas inlet is formed in one end of the straight pipeline, and a gas outlet is formed in the other end of the straight pipeline; the engine electric supercharger structure further comprises a bypass pipeline which is in the shape of an arc; the two ends of the bypass pipeline are communicated with the two ends of the straight pipeline correspondingly; an electric vortex supercharger is arranged in the bypass pipeline; and the position, connected with one end of the straight pipeline, of the bypass pipeline is provided with a rotary valve cavity in which a rotary valve block is arranged. The engine electric supercharger structure with the bypass valve has the beneficial effects that the engine electric supercharger structure with the bypass valve is provided according to the structural manner of the engine electric supercharger structure with the bypass valve, the problem that the gas inflow amount is little when the gas inflow amount of an engine is low is effectively solved, and the problem that the electric vortex supercharger generates a large voltage loss when the engine runs at a high speed is solved.

Description

Technical field [0001] The invention relates to the field of engines, in particular to an engine electric supercharger structure with a bypass valve. Background technique [0002] When the engine is running at a low intake volume, because there is no electric supercharger in front of the intake manifold, the intake volume is small and the engine efficiency is low. The prior art is generally difficult to solve the problem of small intake air volume when the engine is running at low speed, and the problem that the electric supercharging device is placed in front of the manifold, which causes a large pressure loss when the engine is running with a high intake volume. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an engine electric supercharger structure with a bypass valve, which effectively solves the problem of small intake air volume when the engine is running at low speed, and the electric supercharger is placed in fro...
