Abstract: A suction space is disposed to selectively communicate with a pump working chamber defined at one end of a plunger via a first communication passageway in which a solenoid valve is arranged, or with suction ports formed in the plunger and communicating with the pump working chamber via a second communication passageway having a restriction therein. The solenoid valve alternately opens and closes for ordinary fuel injection during operation of the engine other than at the start thereof. A selector valve keeps the first communication passageway closed and simultaneously keeps the second communication passageway opened for fuel injection through collaboration of the suction ports with the second communication passageway, in place of the alternate opening and closing of the solenoid valve.

Abstract: A fuel injection pump serves to inject fuel into an engine. A movable member adjustably determines the rate of fuel injection into the engine. The fuel injection rate depends on the position of the movable member. A critical position of the movable member defines the boundary between a fuel injection enabling range and a fuel injection disabling range. This critical position is measured. An operating condition of the engine is sensed. The movable member is then controlled on the basis of the measured engine operating condition and the measured critical position.

Abstract: A unique supplemental carburetion device for internal combustion engines producing a primary source of fuel-air mixture for use at idle and low engine speeds resulting in decreased fuel consumption and exhaust emissions comprising a fuel reservoir chamber joined to a source of liquid fuel and determinate fluid communication with a fuel metering chamber. The metering chamber preferably is vented to ambient air pressure contains diaphragm valve means for controlling fluid flow into the metering chamber. Liquid fuel from the metering chamber flows into a nebulizing chamber and is nebulized by interaction with a stream of ambient air or blow-by gases. The fuel-air stream is passed into a venturi throat and vaporized and then passed into an expansion chamber where the stream is expanded under low static gas pressure to a mixture having a pre-determined fuel to air ratio. The mixture exits the device and is delivered into downstream portions of the carburetor throat.

Abstract: In an apparatus for controlling the fuel injection advance angle of a fuel injection pump having a hydraulic type timer with a solenoid valve, the apparatus has a closed-loop control system in which the solenoid valve is controlled so as to be closed or opened in accordance with a first control signal produced in response to a feedback signal showing the actual injection advance angle so that the actual injection advance angle is made to coincide with a desired target injection advance angle when the feedback signal is in a predetermined condition, and the solenoid valve is controlled by a second control signal in the open-loop control mode so as to be continuously closed/opened whereby to regulate the average opening degree of the solenoid valve in order to obtain the optimum injection advance angle when the feedback signal is not in the predetermined normal condition.

Abstract: A liquid fuel injection pumping apparatus for supplying fuel to an internal combustion engine includes, a high pressure injection pump, an electrically operated spill valve which when open during a delivery stroke of the injection pump allows fuel to flow to a drain. The apparatus includes a control valve operable to control fuel flow through passage means to the injection pump, the control valve having three positions in the first of which there is unrestricted flow of fuel, in the second of which there is restricted fuel flow and in the third of which fuel flow is prevented. An angularly movable shaft is provided to close the spill valve and the control valve is connected to a shaft. The shafts exterior of the apparatus are connected to mechanisms whereby when the control valve is moved from the first position to the second position the spill valve will be closed thereby to allow the apparatus to supply fuel at a restricted rate.

The magnetic valve, to this end, engages the hydraulic control of the injection adjuster.

Abstract: In effecting individual cylinder fuel injection control in an electronically controlled diesel engine, wherein rpm variations with every explosion cylinder are detected and compared with one another, the increase or decrease in the fuel injection quantity with every cylinder is learned until rpm variations of the respective cylinders become uniform, and a fuel injection quantity control actuator is controlled with every cylinder, so that engine vibrations due to a dispersion in fuel injection quantity between the cylinders can be controlled, an adaptive correction quantity is determined in accordance with an rpm variation deviation obtained from a difference between a mean rpm variation and rpm variations of the respective cylinders, and the engine temperature or the fuel temperature, and the fuel injection quantity control actuator is controlled with every cylinder in accordance with the adaptive correction quantity, to thereby prevent the divergence of the correction quantity.

Abstract: A cylinder block for an internal combustion engine is provided which includes a plurality of relatively spaced free-standing cylinder tubes disposed within a cooling jacket formed in the block. The cylinder tubes are connectedly supported by, and extend upwardly from, the floor section of the cooling jacket. The jacket floor section is reinforced by at least one elongated rib-like member which is integral with and depends from the underside of the floor section and is located between adjacent cylinder tubes.

Bolt receiving means of the cylinder block are positioned so that, when restraining bolts are introduced and tightened to secure a cylinder head to the block, substantially uniform support of the cylinder tubes from their lower portion is achieved.

At least two control edges are provided in a window-like recess of the control slide, of which the lower edge in each case and possibly the upper one as well extend obliquely; the upper control edge provided in the recess determines the supply onset, in cooperation with the first control bore, and the lower control edge of the recess determines the end of supply, in cooperation with the second control bore.

Abstract: A fuel rail assembly has a pair of fuel rail bodies each of which has a bore extending parallel to the fuel supply passage. Each bore has a plug dividing the bore into inlet and discharge regions. The inlet regions are interconnected by an inlet crossover tube, and each inlet region opens to its associated supply passage through a window and a restriction at one end of the associated fuel rail body to balance fuel flow to the supply passages. At the other end of each fuel rail body, a cross bore extends through the discharge region to the supply passage, and discharge tubes received in the cross bores discharge fuel from the supply passages to a pressure regulator.

Abstract: A centrifugal speed governor, functioning as a minimum-maximum-speed governor, includes an adjusting member which is pivotable for adjusting the supply quantity, and the governor rod of the associated injection pump is adjustable via an intermediate lever by means of the adjusting member and a governor spring which is displaceable counter to the force of associated governor springs. The travel of the governor rod is limited in the direction of an increasing supply quantity by a governor rod stop including a starting spring. With the adjusting member resting on an end stop, the governor rod is pressed away from a basic test position (P) into its full-load position (V), and the differential travel (.DELTA.R) thereby resulting is absorbed by an accumulator in the governor linkage, preferably in the governor sleeve. The deflection stroke (A) of the accumulator is only slightly longer than that required to compensate for the differential travel (.DELTA.R).
