Order your replacement set of Oldsmobile fuel injectors here from our selection of brand-name manufacturers of fuel injectors. When you decide on your new fuel injector, you will hear references to multi-port fuel injection or sequential port fuel injection systems. With multi-ports, there is a fuel injector for each cylinder; each fuel injector is located close enough to spray directly into the intake valve. Sequential multi-port fuel injection uses one injector that opens precisely before the intake valve of the cylinder opens. The latest technology in combustion technology: the direct injection systems. These systems are seen in a lot of diesel and European models, where the injection nozzle is placed inside the combustion chamber itself and the piston uses a depression where initial combustion takes place. But whatever kind of injection system you use, your Oldsmobile fuel injector's mission is to measure the amount and timing of fuel to your engine's cylinder. The injector depends on an electrically operated valve that lets fuel into the engine; it is controlled by the engine's computer. At one end of the injector is a set of small holes to spray fuel into the engine, but only at regulated amounts and volumes. The timing (ie: how long the injection nozzle's remains open) will determine how much fuel is injected, and is controlled by the car's onboard computer. In addition, a separate fuel pressure regulator controls the pressure of the fuel in the injectors.
