Abstract

The invention relates to an electronically controlled piston cooling nozzle control method and system. The method comprises the following steps: acquiring running parameters of an engine; and controlling switch-on and switch-off of an electronically controlled piston cooling nozzle according to the running parameters of the engine and an engine MAP, wherein the running parameters of the engine comprise revolving speed of the engine and load of the engine, and the engine MAP is a preset curve for controlling switch-on and switch-off of the electronically controlled piston cooling nozzle according to the revolving speed of the engine and the load of the engine. By the electronically controlled piston cooling nozzle control method and system provided by the invention, problems that in an existing control method, a cooling nozzle is controlled only on the basis of engine oil pressure, so that thermal efficiency is poor are avoided, operation conditions of the engine are considered comprehensively, the piston cooling nozzle control method with a corrected logic is provided, a piston cooling nozzle is controlled accurately, and thermal efficiency of a piston is improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an electronically controlled piston cooling nozzle control method and system. Background technique [0002] Cooling nozzles belong to the cooling system of the engine, especially on engines with a high thermal load [0003] Generally, there are cooling nozzles, which are usually fixedly assembled on the oil passage of the engine. During the operation of the engine, the cooling nozzles spray cooling oil to the pistons. The lower temperature cooling oil takes away the heat of the pistons through heat exchange and cools the pistons. . [0004] In the existing control method for the engine cooling nozzle, a control valve is provided between the cooling nozzle and the auxiliary oil passage, and the fuel injection quantity of the cooling nozzle is controlled by adjusting the opening size of the control valve. During the control process, the oil pressure of the main oil passage of the...
