In a flywheel assembled from a plurality of parts and having greatly reduced noise proportion for reciprocating-piston engines, especially hand-cranked diesel engines, a first part ( ) comprises at least one steel plate, which is joined to at least one further part ( ) by rivets, bolts, spot welds and/or fitting to achieve bearing contact therewith over an area, such that the parts are clamped against each other.

Flywheel for reciprocating-piston engine

A fuel injection pump for an internal combustion engine has at least one pump piston movably disposed in a piston sleeve in a pump housing. The piston includes a first arrangement operable during a stroke in a suction direction for drawing fuel from a suction side of the pump. The piston further includes a second arrangement operable during a stroke in a delivery direction for first cutting off a connection to the suction side of the pump and then initiating delivery from a working chamber into a pressure line. The piston and piston sleeve are provided with a control arrangement which divides the fuel injection into pre-injection and main injection phases. At least one pressure limiting arrangement is provided and is associated with the working chamber. The limiting arrangement is operable during the pre-injection phase when a predetermined engine speed is reached for maintaining the pressure in the working chamber and in the pressure line at a predetermined level.

Fuel injection pump for an internal combustion engine having

A fuel injection pump for self-ignition internal combustion engines, comprising at least one pump piston which is movably arranged in a piston sleeve and, during its stroke, in one direction draws fuel from the suction side into the working chamber of the pump and in the other direction of travel first cuts off the connection to the suction side and then commences delivery, which is divided into pre-injection and main injection, from the working chamber to the injection nozzle.

Fuel injection pump for internal combustion engines

A multi-cylinder fuel injection engine has a respective fuel injector nozzle associated with each cylinder and has one injector pump which supplies fuel to all of the nozzles. The engine includes a rotatable drive element having a plurality of cams which correspond in number to the number of cylinders, which are uniformly angularly distributed thereon, and which successively act on a delivery element of the pump as the drive element is rotated. A shut-off member is associated with each injector nozzle and can close the fuel supply line to the nozzle's injection orifice, the shut-off member being controlled in dependence on a control criteria which determines the injection timing point. Fuel is thus supplied to all nozzles, but can only flow through a respective one of the nozzles which has its shut-off member moved in response to the control criteria to an open position.
