Abstract

The invention relates to an oil way control method and a control device thereof. A distributor shaft is installed in a center hole of a distributor body. An electromagnetic valve hole is machined in the upper portion of the distributor body. An electromagnetic valve is assembled in the electromagnetic valve hole. Vertical oil channels and a horizontal oil channel are machined right above the center hole. The vertical oil channels and the horizontal oil channel are through. An oil plug is arranged on an outlet of each vertical oil channel. An inner oil channel is machined in the center of the distributor shaft. An oil input ring groove and an oil drainage ring groove are formed in the periphery of the distributor shaft. An oil input groove and an oil drainage groove between which a certain angle is formed are formed in the axial direction of the distributor shaft. The oil drainage groove is communicated with the oil drainage ring groove. According to the oil way control method, by means of the cooperation between a distributor and the electromagnetic valve, an engine controls switching of oil ways under the braking and non-braking working conditions. By controlling parameters of the oil grooves, the oil supply moment and the oil supply amount are controlled, and the motion rule of a valve is controlled indirectly.

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 ...
