To control the gasoline pressure in the fuel rail, this pressure relief valve is in charge. Anywhere between 23,000 and 29,000 PSI is the operating range for common rail injection systems; if fuel pressure exceeds this, the Fuel Pressure Relief Valve will open, allowing the excess pressure to exit into the return system.
The valve’s function is to keep the difference between the steam and oil pressures consistent. So that a flame can be created and a clean burn is accomplished, this ensures the fuel oil is effectively atomized into droplets (mist).
The Global Rail Differential Pressure Valve market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A low differential pressure hydraulic sealing type high-pressure common-rail fuel pump is the focus of the development. It primarily consists of a pump body, a plunger piston, a fuel outlet and inlet check valves, a low differential pressure control valve, a synchronous pressure lifter, and a lubricating oil inlet check valve.
In order to prevent fuel from entering the fit clearance between the plunger piston and the operating cylinder, the lubricating oil pressure is maintained to be slightly higher than the fuel pressure.
The low differential pressure control valve and the synchronous pressure lifter are used to control the synchronous pressure rise and reduction of the lubricating end and the fuel end of the fit clearance between the plunger piston and the operating cylinder.
The fuel pressure is higher than 2200 bar, the precise sliding fit surface between the plunger piston and the operating cylinder is ensured to be lubricated, the reliability and durability of operation are increased, and fuel consumption and emission can be further reduced for an ultrahigh-pressure fuel injection system, and the fuel pump can be used with low-viscosity alternative fuels like diesel eng.
