What is a Pressure Limiter Valve? >> check here

The Pressure Limiter Valve (PLV) controls the fuel pressure in the common rail diesel engine. The use tolerance of PLV is very small and will soon be affected by contaminated fuel and / or fouling.

When the valve is activated, the force of the electromagnet aids the spring, reducing the opening of the valve and so increasing fuel pressure. The valve also acts as a mechanical pressure damper, smoothing the high frequency pressure pulses emanating from the radial piston pump when less than three pistons are activated.

An ECU operated Inlet metering valve (IMV) or Rail Pressure Limiting Valve (PLV) located on the side of the high-pressure common rail is utilised for this purpose. which controls the output volume and pressure in the fuel rail.

Generally, the PLV is available as a replacement unit for a range of Fuel Common Rail.

The Common Rail only compresses the amount of fuel needed to maintain the rail pressure required.

This assists in reducing emissions by reducing engine operating load.

Reducing fuel flow during operation also results in lower fuel temperatures.

Common typical faults affecting PLV operation.

Excess wear, contaminated fuel, or an electrical malfunction with the Pressure Limiter Valve or Pressure Sensor can be created major driveability problems and possible fuel pressure conditions.
