When you drive, your engine uses a combination of sensors to know exactly how much air and oxygen to release into the combustion chambers at any given time. The fuel and oxygen needs change as you speed up, rev the engine harder, or travel at higher altitudes. Specifically, the powertrain control module (PCM) receives information … Read more
Most vehicles from the 1980’s and newer are equipped with advanced electronic fuel injection engines (replacing the carburetor). A major part of this system is the fuel injector. While you may never have a problem with your fuel injectors (especially if you regularly use a fuel injector cleaner), sometimes they get dirty, clogged, or completely … Read more
Air and fuel are the heart of the internal combustion process. The proper amount of air and fuel must enter the internal combustion chamber if the ignition is going to be successful. Otherwise, you might have a situation where your engine either consumes too much fuel or under performs. The engine control unit (ECU) normally … Read more
Every vehicle has a fuel injection system in it. The function of a fuel injector is to spray gasoline into the engine, so it can sustain the internal combustion process. However, these fuel injectors will get cluttered with debris as time goes on. Contaminants like wax, dirt, carbon particles and additives will negatively influence the … Read more
The fuel injectors are the parts of the engine which are responsible for spraying a mist of mixed air and fuel into the intake valve of the engine from where the mixture goes into the piston cylinders for the combustion. The ECU (engine control unit) determines the amount of fuel which is pushed into the … Read more
