摘要： A drive arrangement for a camshaft (3) of an internal combustion engine is fitted with a facility for rotating the camshaft (3) relatively to a coaxial drive wheel (5) having a switching component (6), which interacts via a spur toothing (7) with the drive wheel (5) and via a helical gearing (8) with the camshaft (3) and can be axially shifted by a servo motor (13). The servo motor (13) is disposed at the end of the camshaft averted from the drive wheel (5). This prevents the axial length of the internal combustion engine from being extended beyond the drive wheel (5) by the servo motor.

摘要： A fuel injection system for a mixture-compressing externally ignited internal combustion engine includes a flow sensing member (3) arranged in an air intake duct (1), the member (3) moving in accordance with the quantity of air flowing through the duct so as to actuate a fuel metering valve (7) and to dispense a quantity of fuel to fuel injection nozzles (9) of the engine. The pressure difference in the metering valve (7) is maintained constant by means of a pressure sensitive valve (11) and a differential pressure control valve (20), each of which has two chambers separated by a diaphragm (12 and 21). The differential pressure control valve (20) is actuated on both sides by springs (34, 36 and 54) whose loading stress can be varied according to engine operating parameters. The loading stress of the springs is adjusted by devices for full-load fuel concentration and cold-starting fuel enrichment, and also a device responsive to air pressure changes.

摘要： The improved system for liquid cooling of a rotor of a rotary piston mechanism applies to those types having two housing walls spaced apart by a trochoidal shaped peripheral wall to define a multi-lobed cavity within which a multi-cornered rotor is eccentrically supported for planetary movement, and in which the rotor has a hub portion and peripheral wall portions defining therebetween cooling spaces which communicate with the area exteriorly of the rotor through an opening adjacent each end of the hub portion. The improved rotor cooling system comprises a cooling liquid discharge nozzle disposed in at least one of the housing walls and connecting the discharge nozzle to a source of pressurized cooling liquid. The discharge nozzle is positioned so as to direct emitted cooling liquid into the adjacent rotor opening and the cooling spaces in the rotor.In a narrower aspect of the invention a regulator and valve assembly is provided to control flow of cooling liquid to the discharge nozzle in accordance with the pressure conditions of the cooling liquid and temperature and load operating conditions of the engine.

摘要： In a suction pipe installation for multicylinder internal combustion engine with a collector suction pipe, a suction distributor is connected therewith. Adjacently disposed individual suction pipes form a unitary unit with the collector suction pipe. The individual suction pipes extend from the flanges a curve of more than 90.degree. to connecting flanges. The collector suction pipe 1 is mounted in the chamber enclosed by the individual suction pipes, so that it does not require any additional space. A quiet airflow is formed in the straight line segment of the collection suction pipe 1, and in which an air amount meter 18 for a fuel injection installation is installed.

摘要： A fuel injection system for an internal combustion engine includes an air suction pipe, a throttle valve located in the pipe, and a member, upstream of the throttle valve, which is actuatable by air flowing through the suction pipe so as to move a piston valve to dose a quantity of fuel to a fuel injection nozzle. The system includes a duct which bypasses the throttle valve, the duct having a valve which closes the duct when the throttle valve is closed and when the engine is above the idling speed. Dosing of fuel is thereby stopped during coasting of a vehicle, leading to decreased fuel consumption.

摘要： A fuel injection system for a mixture compressing spark ignition internal combustion engine includes means for injection of fuel into the air intake of the engine. A fuel metering valve dispenses to one or more injection jets a quantity of fuel related to the quantity of air flowing through the intake. An adjustable throttle valve is in the air intake as well as an air flow measuring element which is movable against a restoring force in accordance with the quantity of air flowing through the intake. The measuring element is arranged to actuate a control element of the fuel metering valve. A damping device having a damping element connected to the measuring element is movable to displace fluid between two damping chambers through a throttling passage. One damping chamber is connected to a fuel pump which delivers fuel to the metering valve while the second damping chamber is connected to a discharge port through a thermally controlled outlet valve. A metering trap chamber downstream of the outlet valve is provided with means for emptying the trap chamber after operation.
