Engine oil liquid level stabilization system of engine sump and control method thereof

Abstract

The invention discloses an engine oil liquid level stabilization system of an engine sump and a control method thereof. The engine oil liquid level stabilization system comprises an engine sump, an air bag, an air nozzle, an air joint, an air cylinder and a solenoid valve, and wherein the air bag is fixedly installed at the bottom of the engine sump; the air nozzle is fixedly arranged on the air bag, and one end of the air nozzle communicates with an inner cavity of the air bag; the air joint is arranged on the outer part of the engine sump, and wherein one end of the air joint communicates with the other end of the air nozzle; the air cylinder is arranged on the outer part of the engine sump; and the solenoid valve is a three-position three-way valve, three interfaces of the solenoid valve correspondingly communicate with the external environment of the air bag, the air cylinder and the other end of the air joint. According to the engine oil liquid level stabilization system of the engine sump, the height of the engine oil liquid level is adjusted by the air bag, and thus the normal lubrication of an engine is ensured.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and in particular relates to a system for stabilizing the oil level of an engine oil pan and a control method thereof. Background technique [0002] The operating conditions of the car are very complicated, including steep slopes, steep slopes, road slopes, rapid acceleration, rapid deceleration, etc. This makes the lubricating oil in the engine oil pan easy to deflect to a certain side under the above-mentioned working conditions due to its own inertia or the effect of gravity. This may lead to a momentary vacuum oil suction state at the oil pump suction port, and may also prevent the crankshaft from contacting the oil in the oil sump when the crankshaft rotates at a high speed, thus making splash lubrication ineffective. If this is the case for a long time, the engine will have serious wear and tear. Contents of the invention [0003] One of the purposes of the present invention ...
