Ram type engine air intake system for vehicle

Abstract

The invention discloses a ram type engine air intake system for a vehicle. A filter net of the air intake system is arranged at the windward position of a vehicle body, or the outer part of the vehicle body is provided with an air filter air inlet with a forward opening. Filtered air enters an engine air inlet pipe via a cavity or a pipeline. The filter net or the air filter air inlet is arrangedat the air outlet side of a water tank. The filter net or the air filter air inlet is arranged at the air inlet side of the water tank. An air inlet duct or an air filter is arranged at the outer partof the vehicle body or at any side or both sides of the water tank. All or part of air passing the air inlet duct or the air filter enters an engine after being heated by the inner part of the watertank, or the rear part of the water tank, or the upper part of the water tank, or the inner part of an engine exhaust pipe or the periphery of the exhaust pipe. The ram type engine air intake system has the beneficial effects that high-speed air flow forms shock pressure on the filter net, overcomes the resistance of the filter net and increases air intake flow, and the problem that insufficient air supply causes low engine efficiency, high energy consumption, severe exhaust pollution and the like is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle engines, in particular to a ram type vehicle engine air intake system. Background technique [0002] The existing vehicle engine intake system is a natural intake or turbocharged intake structure. The disadvantage of the natural air intake system is that most of the air intake openings are set inside the car body, and the air intake openings are very small and have no stamping effect. For some air filters installed outside the car body, the air intakes do not open forward, and the air intakes are very small and have no stamping effect, so they cannot generate enough air intake pressure to overcome the resistance of the filter to meet the requirements of the engine. Air intake requirements. Especially when the engine is running at high speed, the air intake flow increases, and the resistance of the filter screen increases with the increase of the air flow, resulting in insufficient air supply, re...

Problems solved by technology

The disadvantage of the natural air intake system is: most of the air intake openings are set inside the car body, the air intakes are very small, and there is no stamping effect

For some air filters installed outside the car body, the air intakes do not open forward, and the air intakes are very small and have no stamping effect, so they cannot generate enough air intake pressure to overcome the resistance of the filter to meet the requirements of the engine. Air intake requirements

Especially when the engine is running at high speed, the air intake flow increases, and the resistance of the filter screen increases with the increase of the air flow, resulting in insufficient air supply, reduced engine efficiency, and serious exhaust pollution.

The winter temperature in the north is low, which reduces the efficiency of the engine and increases the fuel consumption
