Abstract

The invention provides an engine intake system, an engine intake control method and a vehicle to solve the problem that dynamic response performance is insufficient during dynamic variable load of a vehicle in related technologies. To achieve the above purpose, the embodiment of the invention provides an engine intake system. The system comprises an intake pipe of a fuel cell engine, an intake parameter sensor arranged at the intake pipe, an air storage tank, a first pipeline for connecting an air outlet of the air storage tank and the intake pipe, a first electronic control valve arranged onthe first pipeline, an FCU controller, and an intake compensation controller, wherein the FCU controller is respectively connected with a CAN bus of the vehicle, the intake parameter sensor and the intake compensation controller; and the first electronic control valve is connected with the intake compensation controller.

Description

technical field [0001] The present disclosure relates to the field of vehicle engineering, in particular, to an engine air intake system, an engine air intake control method and a vehicle. Background technique [0002] In related technologies, when the vehicle's cathode pressurized intake air fuel cell engine system is dynamically changing loads, due to the response characteristics of the electric air compressor (abbreviation: air compressor) of the intake system, it cannot meet the requirements when the load power is rapidly increased. The demand for air intake leads to insufficient dynamic response performance when the vehicle dynamically changes load. Contents of the invention [0003] The disclosure provides an engine air intake system, an engine air intake control method and a vehicle to solve the problem of insufficient dynamic response performance when the vehicle dynamically changes loads in the related art. [0004] In order to achieve the above object, in a firs...
