    • In a four-stroke internal combustion engine for driving a motor vehicle, a throttle flap holding back the exhaust gases during vehicle braking is arranged in the outlet channel. Each of the outlet valves controlled by a cam shaft via rockers has assigned to it a limiting device by means of which the stroke of the outlet valves is limited during braking to an amount which prevents the outlet valves from closing. To increase the engine braking power in an internal combustion engine of this type, the stroke of the outlet valves is limited to an amount at which the opened outlet valves achieve a braking effect, and there is a directional valve which is adjustable as a function of the brake-pedal travel and by means of which the throttle flap and the limiting devices can be actuated.
    • 在用于驱动机动车辆的四冲程内燃机中,在出口通道中布置有在车辆制动期间阻止废气的节流阀。 通过摇臂由凸轮轴控制的每个出口阀都赋予了限制装置,通过该限制装置,出口阀的行程在制动期间被限制到防止出口阀关闭的量。 为了增加这种内燃机的发动机制动功率,出口阀的行程被限制在开启的出口阀获得制动效果的量,并且存在可作为 制动踏板行程,并且通过该行程可以启动节流阀和限位装置。
