About Fuel Cut Off Units

The Citroen fuel cut off unit is an important part of the fuel system in an internal combustion engine that functions to stop or cut off the flow of fuel when necessary under certain conditions. The car's ECU is constantly monortering a whole host of factors, using information supplied by various snesors, to ensure everything is running as it should be. If the ECU deems it necessary to stop the fuel to the engine because the condtions are not right, the fuel cut off unit will cut off the flow of fuel to the engine which helps to preventi detonation and damage to engine components.

In a fuel injected engine, the electric fuel pump/fuel injector injection pump operates with a fuel injection relay, and works by spraying a light, high pressured mist of fuel from injectors into the chambers of the engine, controlled by the computerised control unit, which manages the timing of this process. The fuel injection relay opens and closes the contacts that provide voltage to the fuel pump/fuel injectors. The injectors are fitted close to the inlet manifold, one for each cylinder, and are all calibrated (adjusted) to equally spray a mist of fuel into the intake of each cylinder in a sequence controlled electronically, for the sequential firing of the engine. If mechanical faults are detected or if there are unusual temperatures in the engine, upon instruction from the car's ECU, the electrical current to the solenoid on the fuel cut off unit will be stopped and the valves that allow fuel into the cylinders will close, preventing fuel from entering the engine.

Essentially a safety shut off valve operated by a solenoid, the fuel cut off unit has a spring mechanism which immediately closes the valve when the electrical current to the solenoid is stopped. In order for the valve to be opened again the solenoid must be recharged with an electrical current again.

There are many things that can go wrong in the fuel system, so it's a good idea to consult with your mechanic to establish the exact cause of the fault before buying replacement parts. Specifically designed for the make and model of your vehicle, the Citroen fuel cut off unit is the ideal choice when replacing this part, providing a component that will install well, perform properly and have a long service life.

Citroen trivia

  • Between 1925 and 1935, the Eiffel Tower was just a big, pointy billboard with the word 'Citroën' in bright lights from top to bottom. This was the first use of lights to advertise on the tower, and Citroën renewed the adverts every year until they were bought out by Michelin.
  • French president Charles de Gaulle's life was saved by Citroën not once, but twice. In 1961 a Citroën DS managed to stay intact despite there being a bomb made of plastic explosive, dynamite, oil, and nails. It even managed to drive away from the scene. In 1962, de Gaulle was attacked again, this time with machine guns, but the Citroën again managed to get away from the would-be assassins.
  • The founder of the company, André Citroën, is renowned as something of a genius when it comes to marketing. He specifically targeted adverts for the 1922 Citroën Type C at women owners, and soon after the car became very popular, earning the nickname 'Petit Citron' after the distinctive lemon yellow paint job.
  • John Lennon appeared in an advert for the Citroën DS3, many years after his death. The advert caused quite a lot of public criticism for Yoko Ono, who agreed to the musician's likeness being used.
  • Thanks to Citroën, the French driver Sebastien Loeb is the single most successful driver in the entire history of the World Rallying Championship. Nine consecutive driver's titles were won by Loeb in the time between 2004 and 2012, driving cars such as the Xsara, the C4, and the DS3.
