In a fuel injection system, the fuel is sprayed through the fuel injection nozzle into the combustion chamber. For good combustion, the injectors must produce a fine cone-shaped mist of fuel vapor. Wear or deposits in the nozzle can create "streamers" of liquid fuel that vaporize and burn poorly. This, in turn, can cause hesitation, emissions and performance problems.
Fuel injection cleaning removes deposits from the fuel injection nozzle and clears the way for that fine mist of fuel to come through.
Fuel injection cleaning will help increase performance, eliminate hesitation, improve gas mileage and lower exhaust emissions.
