  • Inlet manifold arrangement for a four-stroke combustion engine
    Patent number: 10465638
    Abstract: An inlet manifold arrangement is disclosed for a four-stroke internal combustion engine having at least one working cylinder with inlet valves and outlet valves and an inlet manifold assembly. The inlet manifold assembly has a flow direction for fluid (such as a fuel-air mixture) in the inlet direction, and an end section near an air filter device. The manifold assembly also has a throttle valve arrangement and a non-return valve which blocks in the direction opposite to the flow direction. The non-return valve is situated, in relation to the flow direction, between the end section of the inlet manifold assembly and the throttle valve arrangement.
