Engine air admittance regulation system

Abstract

An engine air-in control system is disclosed, which utilizes that an air-in control device is connected with a respiratory flexible pipe of the engine, and is used for sucking air leakage of the respiratory flexible pipe of the engine to mix with outer gas, and then the mixed gas is sent to the engine to rekindle, wherein the air-in control device is provided with a pressure induction valve, a suction port, a core vent and a pore which is connected with sub-atmospheric pressure, wherein the core vent and the pore which is connected with sub-atmospheric pressure are directly or indirectly communicated with an air inlet of the engine to produce pressure difference change by utilizing the change of the air-in speed of the engine in order to close or change the opening amplitude of the pressure induction valve, the better air-in control device is provided with an adjusting button which controls opening limiting of the valve and enables the air-in control device to be suitable for the engine air-in control with various inspiratory capacity.

Description

technical field [0001] The present invention relates to an engine air intake adjustment system, in particular to an engine intake air adjustment system which allows engine blow-by air to mix with outside air through an air adjustment valve and then re-sent into the engine for combustion. Background technique [0002] The rocker cover of the automobile engine is equipped with a crankcase forced ventilation system, which is generally called a positive crankcase ventilation device (Positive Crankcase Ventilation, PCV). The PCV device is usually located between the crankcase through hole and the intake manifold. [0003] The purpose of setting up the PCV device is to prevent the gas leaking from the engine combustion chamber into the crankcase [containing harmful gases such as hydrocarbons (HC) and carbon monoxide (CO)] from being directly discharged into the atmosphere, and the engine is used The suction force of the air draws it from the intake manifold into the combustion cha...

AI Technical Summary

Problems solved by technology

[0011]1. The oil gas leaking from the engine combustion chamber to the crankcase directly enters the air pipe and intake manifold 23 from the breathing hose 24, and condenses when the temperature of the cold air drops On the pipe wall, causing oil stains that cannot be removed

[0012]2. The engine air intake adjustment device 1 used in the existing system cannot effectively adjust the openable limit position of the valve piston 14, so as to meet the engine air intake requirements of all different specifications
