Abstract

The invention discloses an engine air inlet control system and method. The system comprises an air inlet pipeline communicated with an air inlet of an engine, an air inlet branch communicated with the air inlet pipeline through a control valve, a temperature sensor arranged at an inlet of the air inlet pipeline, a heater, a cooler and a controller connected with the control valve, the heater, the cooler and the temperature sensor, wherein the heater and the cooler are arranged in the air inlet branch; and the controller receives the current temperature detected by the temperature sensor, determines a preset temperature range corresponding to the current working condition, and controls the control valve to be opened, controls the heater to heat or controls the cooler to cool when the current temperature is not matched with the preset temperature range so as to communicate the air inlet pipeline with the air inlet branch. Air in the air inlet pipeline and the air inlet branch is mixed and conveyed to the air inlet of the engine. The temperature of the air in the air inlet branch is controlled according to the current working condition, so that the mixed air meets the temperature requirement of the current working condition, the actual air inlet temperature of the engine is monitored and controlled, and the working efficiency of the engine is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an engine air intake control system and method. Background technique [0002] The engine is one of the most important components in a car, and its function is to provide power for the car. When the engine is working, the main factors affecting its work efficiency are intake air temperature, intake air humidity and intake air pressure. Existing automobiles cannot monitor and control the actual air intake of the engine, resulting in low engine work efficiency. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide an engine air intake control system and method, aiming at solving the technical problem that the existing automobiles cannot monitor and control the...
