Vehicle, engine component and method for controlling engine oil temperature

Abstract

The invention discloses a vehicle, an engine pack and an engine oil temperature control method thereof. The engine pack comprises an engine and a liquid flow distribution device, wherein the engine comprises a cylinder cover, a cylinder body and an oil pan, a cylinder cover water jacket is formed inside the cylinder cover, and an oil pan liquid flowing interlayer is formed inside the oil pan; the liquid flow distribution device is connected with a water pump of the engine, an outlet end of the cylinder cover water jacket and an inlet end of the oil pan liquid flowing interlayer, and is used for adjusting the proportion of liquid flowing from the water pump and the cylinder cover water jacket to the oil pan liquid flowing interlayer. By the adoption of the engine pack, the temperature of engine oil inside the oil pan can be continuously adjusted, friction loss of engine parts can be reduced, the service life of the engine can be prolonged, oil consumption is reduced, and the starting efficiency of the engine can also be improved. Meanwhile, an engine oil cooler of an engine lubricating system can be omitted, so the structure of the engine is more compact and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to an engine component, a vehicle with the same and a method for controlling the temperature of engine oil. Background technique [0002] For the engine used in the vehicle, the operating conditions are more complicated. During the cold start and low-to-medium speed and low load stages, the temperature of the oil in the lubrication system is too low, which directly leads to excessive viscosity of the oil, which will cause cold start of the engine and The oil flow resistance is too large at low and medium speed and low load, and the oiling is slow, which makes the time from engine start to the oil entering the friction surface too long, and the amount of wear is seriously increased. At the same time, the high viscosity oil also causes friction between parts The resistance increases, and the friction loss power increases. In addition, the excessive viscosity of the engine oil will a...

Problems solved by technology

[0003] Among the existing control technologies for the oil temperature in the oil pan, one is to install a heating device in the oil pan in order to increase the engine oil temperature during cold start and low-to-medium speed and low load. The oil temperature is too low and the viscosity is too high during cold start, but it cannot solve the problem of high oil temperature and low oil viscosity when the engine is running at high speed and high load. At the same time, adding a heating device will increase the cost of the engine

The other is to introduce cooling water into the interlayer of the double-layer oil pan composed of the inner shell and the outer shell to reduce the temperature of the oil in the oil pan at high engine speed and high load, and reduce the impact on the engine caused by the low viscosity of the oil , but it cannot improve the engine oil temperature when the engine is cold-started and low-to-medium-speed and low-load. The problems of low oil temperature and excessive viscosity have not been effectively solved when the engine is cold-started and low-to-medium-speed and low-load, and there is room for improvement.
