Abstract 960,674. Regulating. DAIMLER BENZ A.G. Sept. 10, 1962 [Sept. 14, 1961], No. 34543/62. Heading F1B. In a diesel engine with an engine exhaust brake in the exhaust passage 5, noises occurring in the air filter 9 during engine braking are reduced by means including an air-throttle flap 10 provided in the intake passage 8 and actuated by means in the same opening and closing direction as the braking flap 6. Braking flap 6 is actuated by linkage 7 and operates throttle flap 10 through linkage 11, 12, 13, 13a, 14 and 15. Arm 13a moves more than is necessary to close flap 10 and a spring element 16 takes up the excess movement in link 14. In modifications flap 10 may have one or more small holes to provide an air passage when closed or may close incompletely against an adjustable stop 20. A spring 17 tends to maintain air flap 10 in the open position. The air throttle may be arranged in pipe 2 upstream of an oil-bath air filter 9.
AN ARRANGEMENT FOR REDUCING THE NOISES IN A MOTOR VEHICLE HAVING A DIESEL ENGINE AND PROVIDED WITH AN ENGINE EXHAUST BRAKE, SAID DIESEL ENGINE HAVING AIR SUCTION MEANS INCLUDING A SUCTION LINE, AN AIR INTAKE MANIFOLD AND AN OIL-BATH AIR FILTER BETWEEN SAID SUCTION LINE AND SAID INTAKE MANIFOLD, EXHAUST MEANS PROVIDED WITH ENGINE EXHAUST BRAKE MEANS, SAID ENGINE EXHAUST BRAKE MEANS INCLUDING THROTTLE VALVE MEANS AND MEANS FOR SELECTIVELY ACTUATING SAID THROTTLE VALVE MEANS, AND MEANS FOR REDUCING THE NOISES OCCURRING IN THE OIL-BATH AIR FILTER AND THE SUCTION LINE INCLUDING FURTHER THROTTLE VALVE MEANS WITHIN THE SUCTION MEANS OF THE ENGINE LOCATED TO THE REAR OF SAID OIL-BATH AIR FILTER, AND MEANS OPERATIVELY CONNECTING SAID FIRST-MENTIONED THROTTLE VALVE MEANS WITH SAID SECOND-MENTIONED THROTTLE VALVE MEANS TO OPERATE SAID THROTTLE VALVE MEANS ESSENTIALLY IN UNISON AND IN THE SAME SENSE.
