摘要： In an control apparatus for controlling a timing of injection of fuel to be injected into an internal combustion engine, the apparatus comprises a closed loop system in which the data showing the actual timing of injection of of fuel is fed back. When the condition of the operation of the engine becomes a predetermined state, the control system is changed from the closed loop system to another system in which an adjusting member for adjusting the timing of injection of fuel is controlled by a signal which is not related to the actual timing of injection. As a result, the stability of the operation in low engine speed zone is remarkably improved.

摘要： A fuel injector has a lift sensor in the form of a cylindrical piezoelectric ceramic member having metal film electrodes on each side thereof and which is sandwiched between an insulated terminal element having a flat surface abutting one side of the piezoelectric element and a flat ground plate formed with projections which projections engage the wall of a bore in which the piezoelectric element is disposed so as to both hold the element in place and establish an electrical connection between the housing in which the bore is formed and the second side of the piezoelectric element. A spacing shim having a flat surface abutting the ground plate engages one end of a spring which biases the valve element of the fuel injector toward a closed position.

摘要： An electrical motor controls the movement of a slider threaded over a threaded shaft of the motor. A sensor detects the position of the slider along the threaded shaft to control the movement of the motor which is also controlled by the operational state of the engine. The slider controls the position of a control sleeve fitted slidably over a fuel distributing plunger relative to the plunger so that the sleeve opens and closes a spill port provided in the side surface of the plunger in order to control the amount of fuel supplied to the engine cylinders.

摘要： A governor sleeve is axially displaceable on a stationary governor shaft and has an inner space which is adjoined by the governor shaft and communicated with the inner chamber of a pump housing charged with fuel. The inner space varies in volume drawing thereinto and discharging therefrom fuel in response to axial displacement of the governor sleeve. There is provided valve and channel means which establishes restricted communication between the inner space and the inner chamber upon displacement of the governor sleeve in the direction to produce contraction of the inner space and substantially unrestricted communication between same upon displacement of the governor sleeve in the opposite direction to produce expansion of the inner chamber in order to prevent an acceleration jerk and smoky exhaust.

摘要： A vent valve allows a combustion chamber arranged to burn a swirling lean mixture to communicate with either an intake manifold or exhaust manifold through a vent port by-passing the intake or exhaust valve, for a short period just before ignition to discharge a fraction of the mixture from the combustion chamber. The discharge weakens the turburent flow of the mixture and results in a decreased combustion temperature, which is advantageous for suppression of NOx formation and prevention of combustion noise generation.
