MANNOL Diesel Jet Cleaner is a powerful cleaner for diesel injection nozzles. It cleans soiled diesel fuel injection systems effectively and quickly. It removes tar, combustion residues and deposits from the spray nozzles. Simultaneously, it lubricates the fuel system and protects the system from corrosion. It increases the power, the operating characteristics and the working life of the engine. It removes the hanging-up of the nozzle needle and protects the piston pairs of the high-pressure injection pump as well as the separate parts of the piston assembly from wear. It stabilises revs in neutral, removes starting difficulties, jerking and bad throttle response of the engine, all of which result from uneven fuel injection.
