Problems solved by technology

[0004] (1) Power reduction and economical deterioration
Since the intake air volume of each cylinder is different and the quality of fuel entering the cylinder is the same, the air-fuel ratio of each cylinder will be different, so the adjustment cannot make each cylinder obtain the maximum power or the minimum fuel consumption at the same time, so the overall power, Economic deterioration
[0005] (2) It may lead to a reduction in the life of individual cylinders
[0006] (3) Poor working stability at low speed and low load

Abstract

The invention provides a multi-cylinder engine air intake regulating device, which comprises a regulating valve and an ECU (Electronic Control Unit), wherein the regulating valve comprises a cavity and a plurality of regulating units; the regulating units are vertically arranged in the cavity; the regulating units are mutually parallel; each regulating unit corresponds to one air intake manifold; and each regulating unit is electrically connected with the ECU. The multi-cylinder engine air intake regulating device provided by the invention has the advantages that when an engine operates, a moment motor can be driven through the ECU; a regulating valve plate is further driven to rotate, so that fresh air from an air intake main pipe deflects, is distributed, and flows into the corresponding air intake manifolds; and the reasonable distribution on the intake air of an engine can be realized, so that the power performance, the economic performance and the stability of the engine are improved.

Description

technical field [0001] The invention belongs to the field of engines, and in particular relates to an air intake regulating device. Background technique [0002] In the working process of modern engines, especially small and medium-sized high-speed engines, airflow movement plays a very important role. It is one of the three elements (oil, gas, chamber) in the engine combustion process. The uniform distribution of intake charge in a multi-cylinder engine is an extremely important research direction to improve engine performance. [0003] In the prior art, due to the uneven distribution of the intake charge of the multi-cylinder engine, the following problems will occur: [0004] (1) Power decline and economical deterioration. Since the intake air volume of each cylinder is different and the quality of fuel entering the cylinder is the same, the air-fuel ratio of each cylinder will be different, so the adjustment cannot make each cylinder obtain the maximum power or the mi...
