Air filter air inlet system of fuel cell vehicle

Abstract

The invention discloses an air filter air inlet system of a fuel cell vehicle, and relates to the technical field of vehicle engineering, the fuel cell automobile air filter air inlet system comprises an air inlet leading-in pipe assembly, the air inlet leading-in pipe assembly comprises an air inlet cylinder and an air inlet entering pipe which are communicated with each other, the air inlet direction of the air inlet cylinder is obliquely upward, and the air inlet area of the air inlet cylinder is larger than or equal to the cross sectional area of the air inlet entering pipe; an air inlet of the air filter is connected with an air outlet of the air inlet pipe, and an air outlet of the air filter is respectively communicated with an engine air inlet pipeline and a brake air compressor air inlet pipeline; and one-way valves are arranged in the engine air inlet pipeline and the brake air compressor air inlet pipeline. According to the air filter air inlet system of the fuel cell vehicle, occupied space can be saved, the cost of the whole automobile can be reduced, the air inlet quality can be comprehensively improved, and the maintenance frequency of a brake system dryer is reduced; and meanwhile, air backflow can be effectively prevented, the situation that one air compressor sucks air from the other air compressor when working is avoided, and it is ensured that all air sources come from the air filter.

Description

technical field [0001] The present application relates to the technical field of vehicle engineering, in particular to an air filter intake system for a fuel cell vehicle. Background technique [0002] Currently, fuel cells are the core components of fuel cell vehicles on the market. Through the chemical action of hydrogen and oxygen, it is directly converted into electric power. For fuel cell vehicles, especially medium and heavy-duty fuel cell trucks, the oxygen (air) used for the reaction of the fuel cell engine is sent to the air compressor of the fuel cell engine after being filtered by an air filter intake system. The air brake system of the vehicle and some mechanisms such as airbag suspension, airbag seat, air horn, etc. are compressed through the air compressor of the brake system, and the air source of the brake air compressor passes through another set of air filter and The pipeline is obtained. That is, the air compressor of the fuel cell engine and the air so...
