Fuel injectors spray fuel into a car's engine using electronic controlled valves, capable of opening and closing many times a second. They have an atomising nozzle that distributes the petrol or diesel evenly, for optimum combustion and efficiency. ... A car generally has one fuel injector per cylinder.

With GDI engines, a common fuel line injects gasoline at high pressure directly into the combustion chamber of each cylinder. This gives GDI engines precise control of injection timing and the amount of fuel delivered. ... With gasoline direct injection technology, you can draw more power from smaller engines.

Guidelines When using Fuel Injector Cleaner on Your Vehicle For some products, such as the Red Line Complete that was previously mentioned, a single 15-ounce bottle is suitable for a 20-gallon tank of fuel. Other products, such as the Lucas Fuel treatment, only require a single ounce per 10 gallons of fuel in the tank.

A vehicle's fuel system comprises components that deliver fuel from the tank to the engine, including a fuel pump, fuel lines, a fuel-pressure regulator, fuel filter and fuel injectors. Fuel system components are built to last, so the fuel filter is the only part that's likely to require replacement on a schedule.

Your spark plugs are responsible for sparking combustion in your engine. If they misfire, or are working poorly, this can affect your gas mileage in a negative way. Having bad fuel injectors can cause bad mileage. ... This causes more fuel to be used, and will use up more gas than you need.

Spark plugs are the tiny devices that produce a smooth burn of compressed air-fuel mixture which helps in the ignition process. ... Fuel injectors, on the other hand, are the components which are responsible for fuel delivery in the fuel injection systems.

Fundamentally, the engine ECU controls the injection of the fuel and, in petrol engines, the timing of the spark to ignite it. It determines the position of the engine's internals using a Crankshaft Position Sensor so that the injectors and ignition system are activated at precisely the correct time.

All production vehicles today use computerized fuel injection systems to feed fuel and air into the combustion chamber of the engine. ... After that, you have to let the engine warm up. Otherwise, it simply won't run right. Carburetors on cars operated the same way.

Left unchecked, faulty fuel injectors can damage an engine enough to keep the car from running, but there's usually time to intercept and fix the problem. ... Detonation is harmless in some cases, but the pressure has potential to break engine components and cause pitting and scuffing around the pistons.

Once the fuel injector connector is removed; insert the fuel injector noid light into the connector. It should fit into the connector as easily as the fuel injector did. Do not force the noid light into the fuel injector connector. ... If all is well; the light will flash on and off the whole time the engine is cranking.

The fuel injectors on your car will typically last between 50,000 and 100,000 miles. The length of time that the injector lasts has a lot to do with the type of gas that is used in the car and how often the various fuel filters are changed.
