    The future of mobility: Economical driving, ecological stopping

    Less CO2, less fuel and less expense – automatically and without having to change driving style? Bosch have the answer. A technically sophisticated, highly effective solution: The start/stop system.

    The operating principle of the start/stop system is just as simple as it is efficient: The engine cuts out automatically when the vehicle is stationary. To carry on driving, the engine can be re-started simply by pressing the clutch or, with automatic vehicles, by releasing the brake pedal.

     

    Starting the engine with a start/stop system is extremely quick and economical. Measurements taken in the New European Driving Cycle (NEDC) yielded fuel savings and emission reductions of around 8 %. Savings of up to 15 % are possible in real urban traffic. In combination with a modern gasoline engine, the amount of fuel required for warm starting is only the same as that used when idling for 0.7 seconds. The stop function thus has a beneficial effect right from the very first second - both for people and the environment.
