摘要： In an internal combustion engine with fuel injection, in particular a single-cylinder diesel engine, the injection pump (4) is driven by a rocker (3) actuated by a cam (2) of the camshaft (1). The position of the rocker (3) can be adjusted by an adjusting arm (14) which cooperates with an adjusting member which rocks an eccentric rocker bearing part over a limited distance according to a control variable dependent on the speed of the engine. The swivelling bolt (12) of the rocker is eccentrically mounted on a stationary bearing bolt (13), the adjusting arm (14) is fixedly secured to the swivelling bolt (12) of the rocker and the adjusting member is designed as an oil pressure-dependent slide (17, 18).

摘要： The present invention relates to a pilot-injection control device wherein fuel in a pump chamber is pilot-injected in such a manner that the volume of a variable volume chamber communicating with the pump chamber through a port being on-off operated at a predetermined position of a plunger during a process of pressurizing the pump chamber by the plunger is varied by extending an actuator or the like of an electrostriction-type actuator during a predetermined opening time of the port for example. In the past, the actuator has been driven when the pressure of the variable volume chamber reaches a predetermined value after the start of plunger lifting. However, with this arrangement, the start of pilot-injection does not catch up with a plunger lift during the high speed rotation, whereby main injection and auxiliary injection are conducted continuously. According to the present invention, the on-off time of the port in the previous injection is detected and the time of driving the actuator for the pilot-injection is determined in response to a signal of the detection, whereby, even during the high speed rotation, the time of pilot-injection is determined earlier, so that the pilot-injection is not delayed.

摘要： A method of variably controlling an oil feed rate in an electronically controlled distribution type fuel injection pump, in which the start of feeding of fuel under pressure and the end of feeding of fuel under pressure are controlled with a single solenoid valve. The regions where a cam is used are divided into four modes including a low idle - low velocity low load region, a medium load region, a high load region and a governing - high idle region. The governing - high idle region, the high load region, the medium load region, the low idle - low velocity low load region are arranged in the described order in a direction, in which a cam angle advances from a cam lift 0. The control is conducted such that, in the governing - high idle region, the solenoid valve is closed prior to the start of the cam lift, and, only at the end of the feed under pressure, the valve is opened.

摘要： A fuel injection rate control apparatus for a V-engine, formed so that the rotational speed of the engine can be prevented from varying when the engine is inclined forward or backward, even if a commonly mass-produced inexpensive governor is used. This control apparatus has a fuel injection pump (1) provided with a governor (2) and mounted on one side portion of a cylinder block, a governor-free fuel injection pump (1') mounted on the other side portion of the cylinder block, and a link mechanism consisting of a connecting shaft (41) provided in front of the two fuel injection pumps so that the connecting shaft can be turned freely so as to transmit the movement of a rack rod (3) of the governor-carrying fuel injection pump (1) to a rack rod (3) of the other fuel injection pump (1'), a pair of levers (42-1, 42-2) fixed to both sides of the connecting rod so as to project in the opposite directions, and a pair of links (43) connecting these levers and two rack rods together.

摘要： Servo-motor (14') for auxiliary devices of the internal combustion engine, for example to regulate the injection time point of the injection pump, of which the regulation unit (14) is actuable by the rotation speed-dependent force and operating from the fly-balls (1) of the rotation speed regulator on the abutment (7) of the spring mechanism (6). The derivate of the auxiliary signal depending on the rotation speed provided from the centrifugal regulator is carried out in such a way that the proper direct function of the regulator, the displacement of the rack rods (35) of the injection pump, is substantially not influenced and thereby the reliability of the regulator is not affected.
