Problems solved by technology

The engine oil in the prior art is realized by injecting oil through the oil nozzle. Some existing engines achieve the purpose of not injecting oil at low engine speeds by adding a check valve mechanism to the oil nozzle, but the existing structure does not control the oil nozzle The function is relatively single, and it cannot achieve the purpose of no fuel injection under low temperature and high oil pressure of the engine cold start, and the structure of the nozzle under the current technology is also relatively complicated, and the cost is high

Abstract

The invention provides a technical scheme of a control valve for controlling an engine oil nozzle and a using and control method of the control valve. The control valve is characterized by comprising a valve body, a controller, a solenoid valve and a mechanical valve; the interior of the valve body is provided with an oil inlet and a control port; according to the scheme, a pressure relief oil path is arranged in the valve body, and the on-off of the pressure relief oil path is controlled by the solenoid valve, so that the functions that oil is not injected when an engine is started from cold and at low temperature, oil is not injected at low temperature and low rotating speed, oil is injected at high temperature and high rotating speed and the like can be realized.

Description

technical field [0001] The invention relates to an engine oil control valve mechanism, in particular to a control valve for controlling an engine oil nozzle and a use control method thereof. Background technique [0002] Due to the combustion work of the engine, the moving parts such as the engine piston need to be cooled by oil at high temperature, so as to reduce the working temperature and improve the service life of the engine. However, under low speed and low temperature working conditions, the working temperature of the piston and other moving parts is not high, so no oil injection is required. The engine oil in the prior art is realized by injecting oil through the oil nozzle. Some existing engines achieve the purpose of not injecting oil at low engine speeds by adding a check valve mechanism to the oil nozzle, but the existing structure does not control the oil nozzle The function is relatively single, and it cannot achieve the purpose of no fuel injection under low...
