Abstract

The invention relates to a method and device for controlling the air inflow of an engine, a storage medium and electronic equipment. The technical problem that an existing vehicle with an engine with a low-pressure exhaust gas recirculation system has power lag is solved. The method is applied to the vehicle, the vehicle comprises an engine and a low-pressure exhaust gas recirculation system, and the method comprises the steps that the current opening degree of an accelerator pedal of the vehicle and the current rotating speed and the current torque of the engine are obtained; the target air inlet pressure and the target air inlet amount of the engine are determined according to the current opening degree, the current rotating speed and the current torque; according to the target air inlet pressure, the target air inlet amount and a preset first mapping relation, the target opening degree of a supercharger bypass valve of the corresponding engine is determined; and when it is determined that the vehicle meets the preset power lag condition, an EGR valve of a low-pressure exhaust gas recirculation system is closed, and the actual opening degree of a supercharger bypass valve is controlled according to the target opening degree and a preset correction coefficient.

Description

technical field [0001] The present disclosure relates to the technical field of engines, and in particular, to a method, a device, a storage medium, and an electronic device for controlling an intake air amount of an engine. Background technique [0002] With the rapid development of the automobile and internal combustion engine industries, energy demand and environmental protection issues also follow. Therefore, energy saving and emission reduction have become two major themes of the development of the internal combustion engine industry. [0003] In this context, the low-pressure exhaust gas recirculation (EGR) system is applied to the engine system, and the exhaust gas is catalyzed by the catalytic converter and led out, passed through the EGR valve and the EGR intercooler, and then introduced into the intake air before the intercooler, and the supercharging of the engine. The air intake intercooler and the throttle valve enter the cylinder. By increasing the inert gas c...
