Intake flow sensor adaptive pipeline and engine intake system

Abstract

The invention discloses an intake flow sensor adaptive pipeline and an engine intake system. The intake flow sensor adaptive pipeline comprises an elbow pipe, a flow stabilization pipe, an intake flowsensor and a rectification component, wherein two ends of the elbow pipe are an air inlet end and an air outlet end, the flow stabilization pipe is positioned at an elbow of the elbow pipe, the axisof the flow stabilization pipe is parallel to that of the air outlet end, the intake flow sensor is fixed onto the elbow pipe and positioned at an outlet of the flow stabilization pipe, and the rectification component is arranged in the air inlet end of the elbow pipe. Gas is centralized at the elbow of the elbow pipe to form a flow stabilization area, the flow stabilization pipe is arranged in the flow stabilization area to centralize the gas, the intake flow sensor is arranged at the outlet of the flow stabilization pipe, stable gas flow can be detected, the gas passes the rectification component in the air inlet end before entering the elbow pipe, the gas is rectified by the rectification component, so that the flow speed of the gas entering the elbow pipe is stable and uniform, consistency of intake flow speed in the pipeline is ensured, repetition of the calibration process of MAF (mass air flow) is avoided, and manpower and financial resources are saved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an adaptation pipeline of an intake air flow sensor. It also relates to an engine air intake system including the intake air flow sensor adaptation pipeline. Background technique [0002] MAF (the abbreviation of Mass air flow sensor in English, the Chinese name is the intake flow sensor) is a key component to ensure the normal operation of the Euro VI diesel engine. It is mainly used to measure the intake volume of fresh air entering the engine cylinder. The gas flow rate is extremely sensitive, and the flow characteristic curve of the MAF needs to be calibrated again after the pipeline used to install the MAF is connected or every minor change of the connected pipeline. [0003] However, during the calibration process, due to fluctuations in the intake flow rate in the pipeline, the calibration work is repeated, the calibration process is cumbersome, and wastes manpower and fi...
