Gasoline high pressure oil pump is specially used for direct injection engine components, its role is to improve the system pressure for the oil rail assembly to provide high pressure fuel.
Installation position: 
High pressure oil pump generally consists of four Angle of CAM installed on the intake camshaft drive, lift between 2.5 4 mm, lift is very important for the selection of the high pressure oil pump, a direct impact on cold start when the direct injection system of pressure time, lift need according to the requirements of engine performance, wheel lifter life, CAM contour line driving factors, such as integrated design and manufacturing process, Generally about 3.5mm lift can meet the use requirements.
Working principle:The high pressure pump can provide better fuel economy because it supplies oil to the system on demand: it is made of stainless steel, and the fuel applicability is wide: it has the advantages of light weight, small volume and zero evaporation emissions. High pressure pump with integrated voltage regulator, flow control valve, pressure relief valve single piston pump design, its working principle is through the CAM drive high pressure pump plunger up and down movement to achieve oil absorption and oil. ECU through the pressure sensor on the oil rail, according to the set control program, through the flow control valve to control the flow of the high pressure pump, so as to control the pressure in the high pressure oil rail closed-loop. The function of voltage regulator is to restrain pressure pulsation at low pressure end and improve system stability. The pressure relief valve opens when the pressure in the high pressure oil rail exceeds the safety limit, thus protecting the system.
