Benefits of technology

The present invention provides a system and method for controlling hydraulic pressure and flow rate of oil in an engine. The system includes solenoid valves that control the flow of oil based on engine parameters such as speed, load, and oil temperature. By controlling these valves, the system can prevent frictional loss and unnecessary consumption of oil, resulting in improved engine performance. The control method involves sensing and controlling the engine parameters to optimize oil flow rate for each gallery. Overall, the invention provides a more efficient and effective way to manage hydraulic pressure and flow rate in engines.

Problems solved by technology

The parts in the engine make friction therebetween when generating power and the friction of the parts may reduce the power and decrease the life span of the engine.
However, the oil pressure is different at the oil pump and at the main and head gallery due to hydraulic pressure loss generated through the oil cooler or the oil filter or flow restrictors.
Therefore, it is required to increase very high oil pressure at the oil pump to supply hydraulic pressure corresponding to the desired hydraulic pressure at each gallery, and accordingly, friction increases at the oil pump.
This means oil pumping work should be high and hydraulic pressure loss increase at the oil pump, the oil cooler, and the oil filter and oil consumption is increased by unnecessarily supplying the oil.
