摘要： A fuel injection timing control system for an internal combustion engine into which fuel is intermittently injected, includes a closed-loop fuel injection timing control system, a first device, fluidly-driven, for varying the fuel injection timing, and a second device for adjustably determining the response time and the stability of the closed-loop control system. The first device constitutes a part of the closed-loop control system. The second device constitutes another part of the closed-loop control system. Sensed is a condition of the working fluid for the first device which can influence the response time and the stability of the closed-loop control system. The second device is adjusted in accordance with the sensed working fluid condition so as to reduce the influence of the working fluid condition on the response time and the stability of the closed-loop control system.

摘要： A fuel injection control apparatus for an internal combustion engine for supplying an additional amount of fuel in addition to a basic amount of fuel when an acceleration condition is detected in accordance with a throttle opening change rate. The amount of additional fuel injection is increased in acceleration so as to prevent the fuel air mixture from being lean in acceleration.

摘要： The method and apparatus for generating start of combustion signals associated with the combustion events in a diesel engine (10), and for using such signals to control the timing of fuel delivery to the engine. The combustion event is sensed, as by an electrostatic (230, 330) or optical (130, 430) sensor, and signal conditioning circuitry (32) provides a start-of-combustion (SOC) signal (34) which is directly and precisely indicative of the time of the onset of combustion. The sensors (130, 230) include self-cleaning capabilities (48, 248) for extended operating life on an engine. The sensors may be incorporated in the structure of a glow plug (330, 430). The SOC signal (34) is advantageously supplied to a timing control circuit (26) which delivers a timing control signal (28) to a fuel delivery device, such as the controller (16') associated with a fuel pump (16). The control circuit (26) stores (66) one or more start of combustion values (SOC . ) which indicate the desired timing, relative to an engine cycle (24), for the start of combustion event as a function of speed (26) and load (27). One or more adjustment signals (ASOC) are stored (75) and applied (67,68) as a function of speed and load to adjust the desired signal (SOC * ) such that the control signal (28, SOC c ) is corrected for delays. The actual SOC signal (34) is compared (71) with the desired signal (66) to generate an error signal (72) which may be used to finely adjust the stored (75) ASOC signal for particular speed and load conditions.

摘要： The device comprises a control system (100) commanded by sensing means consisting of at least one optic fibre transmitting a radiation to at least one radiation detector, said sensing means co-operating with a rotating element driven by the engine, which consecutively intercepts the receipt of the radiation. The control system (100) determines the beginning and duration of injection at the injectors (11) incorporated in the fuel-transfer circuit (10), which circuit comprises two pipes, namely a fuel inlet pipe (19) and a fuel outlet pipe (20) which are interconnected and in heat exchange relation and are located at the back of each injector in order to obtain a closed transfer circuit and to ensure continuous circulation of fuel at the back of each injector, thus avoiding in-line vaporization of said fuel.

摘要： A fuel cut-off control can prolong a period of time in which the engine speed is maintained at a range suitable for performing fuel cut-off and shorten a period of time in which the engine speed is in a fuel recovery range to minimize fuel consumption during engine deceleration. In a fuel cut-off control system in a fuel injection internal combustion engine with an automatic transmission, the fuel cut-off control system is responsive to a brake switch signal and an engine speed signal having a value above a fuel recovery threshold to decrease the value of a fuel cut-off threshold to again perform the fuel cut-off even in the normal fuel recovery range. Down shifting of a transmission gear is performed to increase engine speed to a level beyond the fuel cut-off threshold to prolong the fuel cut-off period.

摘要： A method of controlling electronically operation of the internal combustion engine on the basis of results of arithmetic operations of digital control quantities derived from detected operating conditions of the engine through digital processings. The digital processings are divided into a number of tasks in dependence on the control functions to be performed. The method comprises a step of setting an activation request indication for a task through execution of the other task, a step of setting an activation request indication for a task through execution of the task itself, a step of searching the activation request indications for the individual tasks, and a step of executing the tasks to which the activation requests are issued on the basis of the significances of the tasks.

摘要： An engine control apparatus equips with an air flow meter for generating a signal having a frequency proportional to an air flow rate for feeding into the engine. A circuit for monitoring an arithmetic and logic unit is equipped to detect a fault of the arithmetic and logic unit thereby switching a control of a fuel feed valve from the control by the arithmetic and logic unit to a monostable multivibrator so as to prevent an inoperability of a car.
