Unit injectors combine the injection pump and the injector in a single component. Unit injectors supply the right amount of sprayed fuel under the right pressure into the engine cylinder. Unit injectors are very sensitive to poor quality fuel and contaminants in the fuel system. Their failure may also be caused by wrong engine oil.
