Fuel injectors areused in petrol (UK)/gasoline (US) and diesel engines to atomise the fuel into a fine mist so that the fuel burns easily. A fuel injector is actually an electronically-controlled valve that is supplied with pressurised fuel by the fuel pump in the engine. Obviously, all cars, vans, trucks/lorries, motor bikes and anything that has an internal combustion engine have fuel injectors as part of the engine,with one or two injectors per cylinder of the vehicle, and even Wankel engines have fuel injectors.
In the fuel injector, an electromagnet-controlled plunger opens a valve which allows pressurised fuel to squirt out through a tiny nozzle forming a flammable mist that is ignited by a spark from a spark plug which causes the piston in the cylinder to move. The ignition in each cylinder is timed so that the movement of the pistons in transferred into circular motion by the crank shaft and this in turn can be transferred to the wheels of the vehicle.

This product has been described as, “Fabulous and as it says on the bottle, it won’t void the warranty as long as it’s added to a gas engine. I added it to my full tank of gas the night before I drove it (it’s recommended that the tank be at least half full) because I noticed that my 2017 car was running a little rough. Wow! I instantly noticed a huge improvement. Now my engine runs so smoothly that it’s almost silent. It has a fast turbo engine but the difference that STP has made is outstanding and totally unexpected. 0 to 60 in 3 seconds, up from 5 to 6 seconds.”
