Four-stroke internal-combustion engine |
摘要 |
A four-stroke internal-combustion engine for a motor vehicle having inlet and exhaust valves is provided with additional outlet valves for each cylinder, which valves are adjustable by means of an actuating device and with a throttle flap arranged in the exhaust outlet, also adjustable by means of an actuating device. The actuating devices are operated by at least one directional valve, in response to actuation of a brake switch. Braking of the internal-combustion engine occurs as a result of the opening of the additional outlet valves and a throttling of the exhaust gases during the braking operation. The braking of the internal-combustion engine is speed-dependent in that engine braking is cancelled below a minimum specified speed.
