Abstract

The invention discloses a control method, device and system for a piston cooling nozzle and electronic equipment. The method is applied to the vehicle, the vehicle at least comprises an engine and the piston cooling nozzle, and the method comprises the steps that it is detected that the engine is started, engine oil pressure in the engine is obtained, and when the engine oil pressure is larger than or equal to an engine oil pressure threshold value, the environment temperature of the environment where the vehicle is located is detected, so that opening and closing of the piston cooling nozzle are controlled according to environment temperature. The method at least solves the technical problem that the engine warming speed is low in the engine warming process through an existing method of the piston cooling nozzle.

Description

technical field [0001] The present invention relates to the technical field of engines, in particular, to a control method, device, system and electronic equipment for piston cooling nozzles. Background technique [0002] With the development of engine technology, the power of the engine has been continuously improved, and the increase in power will increase the thermal load of the engine, which will increase the temperature of the combustion chamber and piston of the engine, and the excessive temperature of the piston will cause the engine to knock . Therefore, a piston cooling nozzle is usually provided on an engine with a relatively high heat load. During the operation of the engine, the piston cooling nozzle can spray cooling oil to the piston, thereby cooling the piston. [0003] However, the existing technology only determines whether to open the piston cooling nozzle according to the current engine speed and the current load of the engine, ignoring the influence of f...
