Abstract

The invention belongs to the technical field of engines, and particularly relates to a variable-displacement engine oil pump control device and method under the brake working condition. The variable-displacement engine oil pump control device comprises a shell, an engine oil pump inner core, a main oil circuit, a control electromagnetic valve, an electronic control unit, a clutch pedal and an accelerator pedal. A controllable feedback oil circuit is formed on the left side of the inner wall of the shell. A first flow allocation surface is formed at the top end of the controllable feedback oilcircuit. A return spring is fixedly installed on the right side wall of the controllable feedback oil circuit. A normally-open feedback oil circuit is formed on the right side of the inner wall of theshell. A second flow allocation surface is formed at the top end of the normally-open feedback oil circuit. The engine oil pump inner core is fixedly installed in the middle of the inner wall of theshell and further comprises a regulating ring, a bearing, a rotor, blades and an oil supply cavity. The blades are evenly connected to the outer wall of the rotor in an inserting mode, and the oil supply cavity is formed among the multiple blades. By means of the variable-displacement engine oil pump control device and method under the brake working condition, abrasion to a brake is reduced and meanwhile the comprehensive effect of the braking effect is improved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a control device and method for a variable displacement oil pump under braking conditions. Background technique [0002] In recent years, with the increasingly stringent emission regulations and rising oil prices, more and more attention has been paid to energy-saving and emission-reduction technologies for internal combustion engines. Since the variable displacement oil pump can reduce fuel consumption, its application on internal combustion engines has become more and more Wide, variable displacement oil pump can adjust its own oil displacement according to the engine speed and the feedback oil pressure of the lubrication system. When the engine speed increases, the displacement of the oil pump increases, the oil pressure in the main oil passage increases, and when the feedback oil pressure reaches the variable set value, the spring is compressed, and the outer adjustment ring ...
