A fuel injector works much like the spray nozzle of a hose, ensuring that the fuel comes out as a fine mist. The fuel mixes with the air passing through the inlet manifold or port and the fuel/air mixture enters the combustion chamber. Some cars have multi-point fuel injection where each cylinder is fed by its own injector.
In general, they’re expected to last a pretty long time. Both Bosch and Delphi, two major manufacturers of automotive components, say their fuel injectors have a life expectancy of 1 billion cycles. Essentially, that means that the fuel injectors could last as long as the car does. At D.C.Autocare we offer preventative maintenance of your fuel injectors where we can clean them and your combustion chamber of harmful deposits extending the life.
