About Fuel Cut Off Units

The Jaguar 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 Jaguar 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.

Jaguar trivia

• When they first launched in 1922, Jaguar was called the Swallow Sidecar Company. They changed the name in 1945 because of the unfortunate use of the letters 'SS' by Germany in the war.
• The first-ever XK120 rolled off the production line and was delivered immediately to Clark Gable, who had preordered it well in advance. The XK120 came with a removable windscreen and could hit a solid 120mph..
• To show off just how light the F-Pace SUV was, Jaguar built a loop and the SUV not only tackled it but completed the loop on its first go. The feat earned Jaguar a place in the Guinness Book of World Records.
• The most expensive car in Jaguar's history is the XJ220. It cost a rather intimidating £413,000 in 1991 and is also one of the fastest cars they've ever built, capable of getting up to 217mph.
• Transporting a load of Jaguars isn't easy. When being loaded onto trains, every car is driven by a driver that isn't wearing a seatbelt. Those drivers aren't allowed to wear belts, and they even have to get rid of any metal eyelets on their shoes. This is all to prevent the possibility of scratches, and what's more, the drivers aren't even allowed to touch the outside of the cars!
