Disclosed is a control method for engine air input by air intake temperature sensor signal, which belongs to the technical field of improving the gas mixture air-fuel ratio of motor vehicle engine. A controller collects the air intake temperature sensor signal data based on a target air-fuel ratio preset in the controller, oil injection pulse width signal data are utilized to perform feedback correction of the air intake, and correction compensation is performed with reference to speed sensor signal, restrictor position sensor signal, water temperature sensor signal, intake pressure sensor signal and oxygen sensor signal; the air demand for engine gas mixture air-fuel ratio under different conditions is automatically adjusted and controlled by the ratio control and calculation, analysis and comparison embedded in a microprocessor. the control for the engine air input is that the rotating speed of a fan is controlled to realize the optimal control for the gas mixture of the engine, the air intake charge coefficient is adjustable, the combustion of the engine cylinder is sufficient, and the combustion temperature is reduced, the power performance is improved, the emission of harmful gas is reduced, and the fuel consumption is reduced.
Description
technical field [0001] The invention relates to a method for controlling the intake air quantity of an engine by the signal of an intake air temperature sensor, and belongs to the technical field of improving the air-fuel ratio of the motor vehicle engine mixture. Background technique [0002] At present, on the premise of ensuring the power performance of the engine, in order to reduce the fuel consumption of the engine, improve its fuel economy, and reduce the emission of exhaust gas, various technical improvements have been made to the intake system of the engine to increase the intake air volume of the engine, so that The fuel is burned more fully, the power of the engine is improved, and corresponding effects have been achieved. The improvements to the engine intake system in the prior art are as follows: 1. Control the variable length of the intake pipe to improve the intake resonance and increase the charge factor. 2. Change the shape of the original intake pipe of t...
