Works across combustion engines

One patent-protected catalyst in the fuel. The same principle wherever diesel or petrol is burned.

One principle in every engine

  1. Dosed into the fuel

    A small amount, as a tablet or a liquid, goes into the tank or the depot supply.

  2. Travels with the fuel

    It reaches every cylinder together with the fuel, in cars, locomotives, machines and generators alike.

  3. Fuel burns more completely

    Engines use less fuel, emit fewer particles and stay cleaner inside.

7–20 %lower fuel consumption, every test on one axis

Lower fuel consumption measured in field use, from locomotives and machines to generators and cars.
