Abstract: In a motorbrake arrangement for a Diesel engine which utilizes a high pressure fuel reservoir from which fuel is supplied to the injector of each of the various engine cylinders, and each of the cylinders includes a decompression valve which is hydraulically operated for decompression of gas compressed in the engine cylinder during the engine compression stroke, the decompression valve is operable by high pressure fuel admitted to the decompression valve through a control line from the high pressure fuel reservoir under the control of an electromagnetic valve arranged in the control line.

Abstract: In a fuel injection arrangement for a multicylinder internal combustion engine having inlet and exhaust valves operated by rocker arms pivotally supported on a hollow rocker arm support shaft, fuel is supplied from a high pressure fuel pump to fuel injectors mounted on the cylinders through a distribution system which includes a pump discharge line connected to the hollow rocker arm support shaft and distribution lines extending from the rocker arm support shaft to the injectors.

Abstract: In a multicylinder internal combustion engine with cylinder banks arranged in the shape of a V wherein a single cam shaft is supported centrally within the V space between the cylinder banks and push rods are disposed in push rod guides formed alongside the two cylinder banks so as to be operable by the cam shaft for actuating inlet and outlet valves of associated cylinders via rocker arms, fuel injection pumps are supported in mounting openings formed into the cylinder banks along the sides thereof so as to be also operable by the cam shaft for the injection of fuel into the cylinders via injectors mounted to the cylinders, the push rods and the fuel pumps are also arranged in V-shaped rows along the cylinder banks and coolant channels extend along each cylinder bank between the cylinders and the fuel pumps wherein, a cross-sectional plane extending through a particular cylinder, the pump mounting openings, the coolant channels, the push rod guides and the associated cylinder are disposed in a fan-like arran

Abstract: An engine brake arrangement for a multi-cylinder internal combustion engine with at least one throttle valve per cylinder which, during braking operation of the internal combustion engine, is opened at times to connect a cylinder space with an exhaust conduit. To permit simple control of the opening and closing periods of the throttle valves, the latter are actuated by a hydraulic fluid, which is pumped by a pump with a single pressure-increasing and pumping element, and is distributed in a distributor with rotating channels to the individual conduits leading to a particular throttle valve.

Abstract: The invention relates to a solenoid-valve-controlled injection device, comprising pump and nozzle, for an air-compressing internal combustion engine having an electromagnetically actuatable control valve. The valve stem of the control valve co-operates with a control slide which is designed as an inertia piston and, via its control bore and a bore arrangement in the valve stem, establishes a connection between a fuel injection line leading to the nozzle and a return line in order to divide the injection into a temporally staggered pre- and main injection.
