Engine integrated double-inlet double-outlet three-stage filtering air inlet system and engine

Abstract

The invention relates to an engine integrated double-inlet double-outlet three-stage filtering air inlet system and an engine. The engine integrated double-inlet double-outlet three-stage filtering air inlet system comprises an oil bath type coarse filter, two centrifugal prefilters and two paper type fine filters, and two air inlets of the oil bath type coarse filter communicate with air outlets of different centrifugal prefilters. Two air outlets of the oil bath type coarse filter communicate with air inlets of different paper type fine filters, the oil bath type coarse filter comprises an upper shell and a lower shell which are detachably connected, an oil bath space can be defined by the upper shell and the lower shell, a filter screen inner container is installed in the oil bath space, and a coarse filter lower filter screen is installed in the filter screen inner container. A coarse filter upper filter screen is mounted above the coarse filter lower filter screen, and the coarse filter upper filter screen and the coarse filter lower filter screen are fixed through a T-shaped filter screen fixing bracket. The lower end of the oil bath space communicates with an air inlet of the oil bath type coarse filter, and the upper end of the oil bath space communicates with an air outlet of the oil bath type coarse filter.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine integrated double-inlet and double-outlet three-stage filter air intake system and method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Independent innovation in the manufacturing industry is an important cornerstone for the country to face challenges and achieve independent and sustainable development. In recent years, the number of heavy vehicles in my country has remained at around 7 million. High-power, large-scale transport machinery is an important high-end equipment in the fields of national defense, mining, and infrastructure. These heavy equipment, especially large transport equipment for national defense, have heavy engine workload, harsh working environment and frequent sandstorms. The vehicle air intake system is ...
