摘要： In a distributor type fuel injection pump of the type including a plunger arranged for reciprocating and rotative motion, and a fuel injection quantity setting member slidably fitted on the plunger and engageable with a cut-off port formed in the plunger and communicating with a pump working chamber, a second cut-off port is formed in the plunger in communication with the pump working chamber, which opens in an outer peripheral portion of the plunger with which the fuel injection quantity setting member permanently slidably engages, and a plurality of spill ports formed in the setting member in a circumferentially spaced relation, which are smaller in number than the cylinders of an engine for use with the pump. When the plunger moves through each delivery stroke in a low engine load region, the second cut-off port engages each one of the spill ports successively to cause injection of fuel into only part of the engine cylinders.

摘要： An apparatus is proposed which serves the purpose of load-dependent actuation of an adjustment device, wherein the cross section and/or the pressure drop of an exhaust recirculation line in an internal combustion engine can be varied in accordance with load. An injection pump of conventional design is associated with the internal combustion engine and further includes a quantity adjustment device, the position of which acts as a control variable for the load. With this control variable, a booster apparatus is controlled via a comparison apparatus; the output variable of the booster apparatus in turn is the control variable for the actuation of an adjustment device which acts on an exhaust recirculation control apparatus. When a threshold value for load is exceeded, the exhaust recirculation is precluded. The control variable is preferably formed as a fuel pressure signal with the fuel withdrawn from the suction chamber of the injection pump. Apparatuses are proposed by means of which, in the event of the actuation of the control apparatus for exhaust recirculation, the smallest possible removal quantity of fuel is required for control purposes.

摘要： In one form of the invention, a rotatable and axially slidable plunger mounted within a fixed cylindrical plunger barrel forms with the barrel the casing bore and a spring biased electromagnetically driven axially slidable cut off sleeve, a dash pot chamber including a narrow radial gap between the cut off barrel and the pump casing body.

摘要： An improved r.p.m. regulator of a fuel injection pump for internal combustion engines includes an improved control spring mechanism. The control spring mechanism is connected to one end of a control lever which in turn is connected at its other end to a fuel supply quantity setting member. The control lever serves to actuate the fuel supply quantity setting member in accordance with the forces applied to the control lever by the control spring mechanism and an r.p.m.-dependent force applying structure which applies a force to the control lever in opposition to the force applied by the control spring mechanism. The control spring mechanism includes a compression spring mounted between the control lever and a setting lever, a first connecting member and a second connecting member. The first connecting member is connected to that end of the control spring furthest from the setting lever, while the second connecting member is connected to that end of the control spring furthest from the control lever.

摘要： In a fuel injection apparatus in which the terminal moment of the injection during each pressure stroke of the pump piston is determined in an engine rpm-dependent manner by the position of the governor member of a centrifugal governor, the beginning moment of each injection is determined by a setting mechanism which is responsive to the output pressure of a fuel pump serving the fuel injection apparatus. Said output pressure, in turn, is a function of the position of said governor member.
