摘要： A start-up failsafe system for an engine control system monitors a command signal and the corresponding feedback signal for a fuel injection rate control servo device when the starter motor switch is closed. If the feedback signal and the command signal differ by more than a predetermined amount, the failsafe system acts to prevent operation of the starter motor.

摘要： A failsafe system for an engine-control servomotor compares a servomotor command signal to a feedback signal from the servomotor. When the magnitude of the difference between the two signals is greater than a predetermined value for a predetermined time, the failsafe system shuts down the servomotor or performs some other engine shut-down procedure. The failsafe system includes a comparator for comparing the two signals, the output of which leads to two other op-amp-type comparators connected in parallel, which work on negative or positive outputs of the first-mentioned comparator, respectively. Each of the later comparators receives a reference voltage input against which to compare the output of the first-mentioned comparator. Their outputs lead parallelly to time-delay circuits which check for a positive output for a predetermined length of time by a well-known capacitor-integration technique.

摘要： An adjusting system for crank angle sensor signal comprises a crank angle sensor, a timing detector and an adjusting unit including an output control device. The crank angle sensor is associated with an engine crankshaft and produces first and second signals. The first signal is indicative of a predetermined crankshaft position for each engine cylinder and the second signal is indicative of rotation of the engine crankshaft through a unit angle. These signals are used for controlling fuel injection timing or spark timing. The timing detector measures the difference between an actual value and a target value with respect to a desired timing, which timing is, for example, fuel injection timing, spark timing, or a predetermined crankshaft position for each engine cylinder. The output control device is provided at a safe place away from various engine rotational parts and is manually operable to change its output as a correction value. The adjusting unit is adapted to adjust the first signal in response to the output of the output control device to make the actual value coincide with the target value so that the first signal is electrically adjusted safely and efficiently without moving the crank angle sensor itself to attain optimal fuel injection timing or spark timing.

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.
