Engine air intake system suitable for minibus

Abstract

The invention discloses an engine air intake system suitable for a minibus. An air filter assembly is vertically mounted outside a vehicle frame right longitudinal beam through an air filter mounting bracket and located on the back position under a co-driver seat; an air outlet end of an air intake pipe of an air filter is connected to the front side wall of the air filter assembly, an air intake end of the air intake pipe of the air filter penetrates through a vehicle floor under the co-driver seat and extends into the vehicle, the air intake end of the air intake pipe of the air filter is fixedly arranged on the vehicle floor through a mounting disk in combination with bolt and nut assemblies, and a filter screen is arranged in the air intake end of the air intake pipe of the air filter; an air intake end of an air intake pipe of an engine is connected to the top of the air filter assembly, and an air outlet end of the air intake pipe of the engine horizontally extends towards the longitudinal central line of a vehicle frame, then extends forwards and is connected with an air inlet of the engine. According to the engine air intake system suitable, the method of in-vehicle air intake is adopted, the phenomenon that the air inlet of the air intake system is exposed is avoided and the manufacturing cost is lowered; blockage on the mouth portion of the air intake pipe of the air filter is avoided, the air intake efficiency is improved, and air intake noise is reduced.

Description

technical field [0001] The invention relates to auto parts, in particular to an engine intake system suitable for a van, and belongs to the technical field of mechanical structures. Background technique [0002] At present, vans use air intake from the space outside the vehicle, and the air intake of the van is exposed outside the vehicle, which greatly affects the overall aesthetic coordination. At the same time, the air intake pipe of the air filter is long, the manufacturing cost is high, and the air circulation in the intake pipe If the time is prolonged, the friction time between the air flow and the pipe wall will increase, resulting in a decrease in air intake efficiency and an increase in intake noise; especially for long-term use in an environment with muddy roads and heavy wind and sand, it is easy to cause the air intake pipe opening of the air filter to be damaged. The internal blockage will affect the performance of the engine. Contents of the invention [00...
