Control method and device of engine, storage medium and computer equipment

Abstract

The invention discloses a control method and device of an engine, a storage medium and computer equipment. The ideal pressure ratio matched with the current rotating speed of the engine can be confirmed, and the ideal pressure ratio is the ratio of the back pressure and the front pressure of a throttle valve under the condition that the opening degree of the throttle valve is the maximum and throttle losses are the minimum; the front required pressure of the throttle valve is obtained according to the back actual pressure of the throttle valve at the current moment and the ideal pressure ratio; the target opening degree of a bypass valve is confirmed according to the difference value between the front actual pressure of the throttle valve at the current moment and the front required pressure of the throttle valve, wherein a gas inlet of the bypass valve communicates with a gas inlet of the throttle valve, and a gas outlet of the bypass valve communicates with the atmosphere; and the bypass valve is controlled to reach the target opening degree. The technical means of controlling the opening degree of the bypass valve is adopted, the technical problem that the throttle losses of the engine are increased is overcome, and then the technical effect of improving the heat efficiency of the engine is achieved.

Description

technical field [0001] The present invention relates to the field of engine technology, in particular to an engine control method, device, storage medium and computer equipment. Background technique [0002] Nowadays, as a machine that can convert other forms of energy into mechanical energy, the engine is widely used in various vehicles and mechanical devices, and the throttle valve on the engine, as one of the most important parts of the engine, controls the energy entering the engine. content of the gas. [0003] However, in the actual use of the engine, not all the air in front of the throttle needs to enter the engine. When the gas in front of the throttle is too much than the gas required by the engine, it will increase the amount of air in the engine cylinder after the throttle. The vacuum between the chambers will increase the throttling loss of the engine, resulting in excessive energy consumption of the engine and reducing the thermal efficiency of the engine. ...
