Mazda Fuel Injector: Quality Component for Best Performance

By: Anthony Fontanelle

The Mazda fuel system is one of the most essential parts of a Mazda vehicle for it is responsible for delivering the fuel to the engine as well as ensuring that the fuel is being utilized properly. Without it, a Mazda vehicle won't be able to run at all. The Mazda fuel system consists of different parts. This includes the Mazda fuel injector. After the fuel is screened for harmful impurities that may be present in the fuel filter, it passes through the fuel injector. In such conditions, the Mazda fuel injector is responsible for dispensing the right amount of gas into the cylinders at the right time, in the right way.

A Mazda fuel injector is commonly made up of a pump, a couple of valves, as well as nozzles for shooting fuel into the cylinders of an internal-combustion engine. The fuel injector, of course, is a part of the fuel injection system. The assembly is primarily in charge of measuring and delivering the appropriate amount of fuel into the internal combustion engine. There are two types of Mazda fuel injectors. First is the Port Fuel Injection (PFI). This one operates with an injector per cylinder mounted in the intake manifold so that the injector ends up pointing towards the intake valve. The second is the Throttle Body Injection (TBI). This one, on the other hand, has two injectors mounted in a housing that is greatly similar to a carburetor. In this injector set-up, the fuel is constantly injected into the air stream. By opening and closing, the injectors can accurately measure the suitable amount of fuel that needs to be delivered to the engine.

A properly working Mazda fuel injector contributes to smoother function during quick throttle transitions. It also makes improvements in engine starting as well better extreme weather operation possible. Reduced maintenance intervals and slight increases in fuel economy are also likely. But like any other car part, a is certain to fail, eventually. About less than 5 percent of injector failure, after all, is principally caused by electrical or mechanical breakdown. Fuel injector failure is often brought on by the negligent build-up of deposits as well as the corrosion that causes blockages, ending in fuel flow reduction. Reduced fuel flow, in turn, induces critical high combustion temperature that allows contaminants to harden on the pintle, leading to potential damages to the part. Leaky valve seals and defective spray systems resulting from dirt build-up can also be responsible for injector failure. The best and probably the only way to accurately know if a Mazda fuel injector is working within the right specifications is to pull the injector out of the system and have it "bench tested". By doing so, the part can be analyzed electrically, visually examined for proper fuel spray pattern, flow tested for suitable volume delivery, and leak tested for pintle/seat or mechanical leaks. A typical fuel injector is manufactured to work and last for about 150,000 miles.
