摘要： A fuel injection pump 100 comprises a thermoelement CSD 47 for advancing injection timing in a cold temperature condition. The CSD 47 uses a piston 46 for opening and closing a sub port 42 formed in a plunger barrel 8. An electronic governor 2 is provided with a mechanism for decreasing an injected fuel quantity when an engine starts in a cold temperature condition. The mechanism shifts a rack position in a fuel-decrease direction in a cold temperature condition, and switches the rack position to a normal position in a normal temperature condition. A timing TR for shifting the rack position is set before or simultaneous to a timing TC for switch-off of the CSD 47.

摘要： A prestroke controller 31 for an engine fuel injection pump 30 utilizes a magnetic coupling 26 and, by taking advantage of the fact that the secondary side (driven side internal magnet) of the magnetic coupling can be controlled to a desired position without being driven by force from a flyweight 11 on the primary side (driving side external magnet), not only secures speed timer characteristics but also provides a greater degree of freedom in determining the injection timing advance characteristic. The prestroke controller 31 includes the magnetic coupling 26 as a member of a displacement transfer section provided between the flyweight 11 and the timing control rod 6 and also includes an add-on device 36 for injection timing advance adjustment which can be engaged with or disengaged from the timing control rod 6 and is capable of controlling the prestroke independently of the magnetic coupling 26.

摘要： The present invention is directed to a system for actuating a cam follower shaft to permit variable timing of the valving events or the unit injectors of an internal combustion engine. A rotatable cam follower shaft is subjected to continuous, alternating, oscillating torques. A clutch is disposed adjacent the shaft and is translatable to move from a disengaged position to an engaged position in which the clutch engages the shaft either directly or through roller bearings and separate inclined surfaces. When the clutch engages the shaft, it prevents rotation in a first direction while permitting rotation in a second direction until a positive stop is reached. When the clutch is disengaged from the shaft, the overall torques acting on the shaft rotate the shaft in the first direction until the shaft reaches another positive stop. The clutch is activated by a compression spring which is resisted by fluid pressures.

摘要： A vehicle propulsion system includes a controller configured to generate a control signal that dictates operation of a propulsion system of a vehicle having an engine and an electrically driven superturbocharger or a turbo-compounding turbine. Responsive to determining that the vehicle is one or more of entering into or traveling within an airflow restricting area, the controller is configured to change the operation of the propulsion system of the vehicle by reducing a power output by the engine. The controller is configured to reduce the power output by the engine to increase a power output of the electrically driven superturbocharger or the turbo-compounding turbine to propel the vehicle through the airflow restricting area.

摘要： A device for adjusting a fuel supply advance angle of a multi-cylinder diesel engine includes a gear chamber (3), a connecting disc (5) and a high-pressure fuel pump (2), wherein the gear chamber (3) and the connecting disc (5) are assembled in the diesel engine, and the high-pressure fuel pump (2) is arranged at a left end surface outside the gear chamber. A main shaft end of the high-pressure fuel pump (2) extends into the gear chamber (3) and is connected to the connecting disc (5). A right end surface of the connecting disc (5) is connected to a timing gear (6) of a fuel injection pump. A right end surface of the timing gear (6) of the fuel injection pump is provided with three penetrating circular-arc waist-shaped holes (61) that are away from the center and equally spaced along the circumference direction. Annular sizing blocks (63) are arranged on the waist-shaped holes (61). A penetrating circular hole (68) is arranged at a tail end of at least one of the waist-shaped holes (61) in a counterclockwise direction and away from the waist-shaped hole (61). The circular hole (68) is provided with a T-shaped nut (65), and the axis of the T-shaped nut (65) is in parallel with the end surface of the timing gear (6) of the fuel injection pump. A support screw (67) is arranged in the T-shaped nut (65), and the screw head of the support screw (67) is jacked against the annular sizing block (63). A method for adjusting a fuel supply advance angle of a multi-cylinder diesel engine is also disclosed. The adjusting device and the adjusting method are convenient for adjusting a fuel supply advance angle and therefore have high adjustment precision.

摘要： A control device for driving/controlling an engine on the basis of a signal from a temperature state detector, a rotation detector, and a rotational speed setting device is provided. The control device includes a start temperature determining processing unit configured to determine whether or not a temperature (T) at start of the engine is less than a predetermined temperature (Tw1) and a start control processing is performed in accordance with a set value of a target rotational speed (Nset) by the rotational speed setting device in case the start temperature (T) is equal to or less than the predetermined temperature (Tw1). This suppresses occurrence of cavitation by stopping the start of the engine (10) within a range in which the temperature (T) is equal to or lower than the predetermined temperature (Tw1) and the target rotational speed (Nset) of the engine (10) is higher than a predetermined threshold value (Nca).

摘要： A fuel injection pumping apparatus of the rotary distributor type has an angularly adjustable cam ring to which is connected an arm. The arm is engaged by a surface on a linearly movable actuating member the position of which varies in accordance with the speed of the associated engine. The arm is also engaged with a cam connected to an operator adjustable member which is also coupled to an arrangement for controlling the amount of fuel supplied by the apparatus. The arrangement is such that movement of the operator controlled member effects an immediate adjustment of the timing of fuel delivery, the timing also varying as a result of speed variation.
