About Fuel Injection Relays
The Audi fuel injection relay basically acts as an ON/OFF voltage control switch, allowing an electric current to flow to the fuel injectors that supply fuel to the cylinders of the engine.
The Audi fuel injection relay will be housed in the relay box, usually found underneath the dashboard. The relay connects to the car's battery, as well as connecting to the specific part that the relay is functioning, in this case the fuel injection pump.
In a diesel engine fuel injection is essential but petrol engines also have fuel injection systems. 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. The overall result of this ensures the engine is working to its optimum, providing more power and fuel efficiency.
When you need to change the fuel injection relay, a good quality Audi fuel injection relay will guarantee a part that fits well, performs properly and has a long service life. Relays can fail because of oxidisation, overheating or due to a faulty connection in the relay socket. Faults can occur with the electrical contacts, relay coil and wiring. The connections can overheat and corrode. If there is a problem with any of the relays in your car, the warning light should illuminate on the dashboard. It's always a good idea to consult with your mechanic when fuel system problems strike, to make sure the correct fault has been indentified. It's important when replacing the fuel injection relay to buy a part that will be compatible with the make and model of your vehicle. Buying the Audi fuel injection relay will guarantee you get the right component that's designed specifically for the make and model of your car.
- The oldest car race event in the world, the 24hr Le Mans, has been won by Audi an impressive 13 times, most of which were in the classic R8 racer.
- The RS3 is lighter than you might think. That's because the five-cylinder engine isn’t made from cast-iron but instead from aluminium. That means it only weighs around 26kg!
- You might think that crash tests in cars have always been a requirement, but it was Audi that first started doing them. Far from the modern methods used today, Audi engineers simply let their cars roll down hills until they hit something. Spectators used to line up to watch the excitement.
- Audi has been responsible for many firsts in car design. One of the most impactful was the introduction of the dual-clutch gearbox, first seen in the Quattro S1 E2. Now, of course, they are commonplace.
- The word Audi is a Latin translation of the word Horch, which incidentally is where we get the word audio from!
