Abstract

The invention relates to an oil circuit control method and a control device thereof. The distributor shaft is installed in the center hole of the distributor body, and a solenoid valve hole is processed above the distributor body, and the solenoid valve is assembled in the solenoid valve hole. Right above the center of the distributor shaft, a vertical oil passage and a horizontal oil passage are processed. The vertical oil passage and the horizontal oil passage communicate with each other. The outlet of the vertical oil passage is provided with an oil plug. An oil inlet ring groove and an oil discharge ring groove are provided, and an oil inlet groove and an oil discharge groove at a certain angle are arranged in the axial direction of the distributor shaft, and the oil discharge groove communicates with the oil discharge ring groove. Through the cooperation of the distributor and the electromagnetic valve, the invention realizes the switching of the control oil circuit under the working conditions of engine braking and non-braking. By controlling the parameters of the oil tank, the control of the oil supply time and the amount of oil supply is realized, and the movement law of the valve is indirectly controlled.

Description

technical field [0001] The invention relates to an engine oil supply system, in particular to an oil circuit control method and a control device thereof. Background technique [0002] When the car is going down a long slope and the driver activates the engine braking device, the oil supply system stops supplying oil, and at the same time, when the engine is close to the top dead center in the compression stroke, the exhaust valve is opened by a small lift under the drive of the engine braking device. (1 ~ 2mm), the compressed high-pressure gas in the cylinder is released quickly, and the pressure in the cylinder decreases rapidly, so in the next power stroke, the engine basically does not work externally. The external high-pressure oil pump is used to provide high-pressure oil, and the brake valve is pushed to open at the set time to realize engine braking. [0003] In the prior art, the control of the engine brake oil circuit and the non-brake oil circuit is realized by a ...
