About Fuel Cut Off Units

The BMW 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 BMW 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.

BMW trivia

• It might not be the accessory that everyone needs, but for BMW drivers in South Africa who were worried about carjackers, the 'Blaster' was a flamethrower that shot huge flames from either side of the car. Not currently available in the UK…
• One of the reasons older BMWs keep their value is because it's easy to get spare parts for even the oldest models. That's because BMW has carried on making car parts, even for cars that were built in WWII.
• The main headquarters for BMW in Munich is designed and shaped to look like car parts. There was a whole new 'four-cylinder' building added on in 1973, and there's definitely the look of an engine about the architecture.
• Did you know that BMW built a Lamborghini? The two popular companies decided to make a race car together, but Lamborghini pulled out during the manufacturing process. BMW carried on, and the final result was the original BMW M1 supercar.
• The BMW company was founded way back in 1916 and originally manufactured engines for planes. High demand for plane engines during WWI was good news for BMW, but they carried on making plane engines right up until 1945.
