Engine control method and device, electronic equipment and storage medium

Abstract

The invention relates to the technical field of engines, provides an engine control method and device, electronic equipment and a storage medium, and aims at enabling an engine to obtain proper pre-lubrication before starting and prolonging the service life of the engine. The method comprises the steps that the corresponding engine oil temperature value of an engine at the current moment and the initial engine oil pressure value are obtained; determining a target engine oil pressure value corresponding to the engine oil temperature value according to a pre-configured corresponding relation between the engine oil temperature value and the engine oil pressure value; controlling an engine oil pre-supply pump to pre-supply engine oil to the engine so as to adjust the initial engine oil pressure value; and when it is determined that the relation between the adjusted initial engine oil pressure value and the target engine oil pressure value meets a preset condition, the engine is controlled to be started. Due to the fact that the required engine oil pressure value is set according to the different engine oil temperature values, and the engine is controlled to be started after the set engine oil pressure value is reached, the engine can be properly pre-lubricated before being started, and the service life of the engine is prolonged.

Description

technical field [0001] The present application relates to the field of engine technology, and provides an engine control method, device, electronic equipment and storage medium. Background technique [0002] The high-power engine must pre-supply engine oil before starting, and the engine is not allowed to start until the pressure value of the pre-supplied oil reaches the set value. The pre-supply of engine oil can pre-lubricate the friction pairs of the engine before starting, avoid scratches between the friction surfaces during the starting process, and prolong the service life of the engine. [0003] In related technologies, the following two methods are mainly adopted to control the pre-supply oil of the engine before starting: [0004] Method 1: Set a fixed pre-supply oil pressure setting value in advance, and start the engine when the pre-supply oil pressure value reaches the set value. [0005] Method 2: Set a pre-supply time set value in advance, and start the engin...

Problems solved by technology

[0006] However, in the above method 1, when the set value of the pre-supply oil pressure is high, the oil pressure cannot reach the set value in a certain temperature range, and it is difficult to start the engine. When the set value of the pre-supply oil pressure is low, the oil pressure The value is easy to reach the set value, resulting in insufficient engine pre-lubrication, scratches between the friction surfaces during the starting process, and shortening the service life of the engine; The pre-supply pump working for a long time will consume a lot of battery power, shorten the service life of the battery and the engine, and when the pre-supply oil time is set for a short time, it will cause insufficient engine pre-lubrication
