  • Patent number: 10288012
    Abstract: Methods and systems are provided for introducing water into an intake manifold of an internal combustion engine. In one example, the system may include a water container, a water inlet for inputting water into the intake manifold, and a throttle valve that is arranged between an intake manifold inlet and the internal combustion engine, with the water container arranged at a higher point than the water inlet and the water inlet opening into the intake manifold downstream of the throttle valve. A switchable valve is arranged in fluidic connection with both the water container and the water inlet, with the result that it can enable or interrupt the introduction of water into the intake manifold and also create a Venturi effect at the water inlet, which draws water from the water container.
