High Pressure Oil Pump

The design criterion of the fuel supply of a high pressure oil pump is the need to ensure the demand for the amount of fuel injection and the amount of oil controlled under any circumstances, as well as the change in the amount of oil when starting and accelerating.

The design criterion of the fuel supply of a high pressure oil pump is the need to ensure the demand for the amount of fuel injection and the amount of oil controlled under any circumstances, as well as the change in the amount of oil when starting and accelerating. Because the fuel injection pressure in the common rail system is not related to the fuel injection process, and the injection timing is not guaranteed by the cam of the high-pressure oil pump, the pressure oil cam of the high pressure oil pump can design the cam according to the minimum peak torque, the minimum contact stress and the most wear-resistant design principle.

Most companies use diesel engine driven three cylinder to plunger pump to generate up to 135MPa pressure. The high pressure oil pump adopts multiple oil pressure cam in each oil pressing unit, which reduces the peak torque to the 1/9 of the traditional high pressure oil pump, and the load is more uniform, and the operation noise is reduced. The pressure control in the high pressure common rail chamber is achieved through the discharge of the fuel in the common rail cavity. In order to reduce the power loss, the oil supply will be reduced by closing the three cylinder diameter to the plunger pump in the case of small fuel injection.
