Problems solved by technology
Naturally aspirated engines have the problems of low intake air volume, large fuel injection volume, high fuel consumption, and insufficient combustion at the start; in plateau areas, due to the thin air, there is also the problem of insufficient intake air volume, resulting in a significant drop in power performance
When the turbine is added to the engine, the above-mentioned problems also exist when the turbine is involved in the rotation speed above 1200 rpm, and in order to increase the intake air volume, the high rotation speed of the turbine leads to high temperature, and special heat dissipation equipment is required

The invention relates to a control method and device of an engine air intake system, the engine air intake system and a vehicle. The engine air intake system comprises an air intake branch and an oxygen storage device air intake branch, and the method comprises the following steps that the target oxygen supply mode required by the engine air intake system at present is determined, and the target oxygen supply mode is one of an air oxygen supply mode, an oxygen storage device oxygen supply mode and a mixed oxygen supply mode; according to the target oxygen supply mode, the on-off state of the air intake branch and the oxygen storage device air intake branch is controlled, and if the target oxygen supply mode is the air oxygen supply mode, the air intake branch is controlled to be connectedand the oxygen storage device air intake branch is controlled to be disconnected; if the target oxygen supply mode is the oxygen storage device oxygen supply mode, the air intake branch is controlledto be disconnected and the oxygen storage device air intake branch is controlled to be connected; and if the target oxygen supply mode is the mixed oxygen supply mode, the air intake branch and the oxygen storage device air intake branch are controlled to be connected simultaneously, and in this way, according to the actual environment of an engine, the oxygen supply mode of the engine air intakesystem can be intelligently adapted.
Description
technical field [0001] The present disclosure relates to the field of engines, in particular, to a control method, device, system and vehicle of an engine intake system. Background technique [0002] Existing fuel engines can be divided into two types: naturally aspirated engines and turbocharged engines. Naturally aspirated engines have the problems of low intake air volume, large fuel injection volume, high fuel consumption, and insufficient combustion at the start; in plateau areas, due to the thin air, there is also the problem of insufficient intake air volume, resulting in a significant drop in power performance. The turbine increases the engine, because the turbine intervenes when the speed is above 1200 rpm, there are also the above problems, and in order to increase the air intake, the high speed of the turbine leads to high temperature, and special heat dissipation equipment is required. Contents of the invention [0003] The purpose of the present disclosure is...
