Abstract: A method of operating an internal combustion engine of a motor vehicle provided with a vacuum accumulator which provides an auxiliary energy required for at least one servo function of the internal combustion engine in form of a vacuum and which is acted upon by a vacuum acting in a suction pipe of the internal combustion engine. The method computes a pressure acting in the vacuum accumulator, supplies mass flows to the vacuum accumulator when at least one servo function is performed, and withdraws the mass flows from the vacuum accumulator when a pressure acting in the suction pipe is smaller than the pressure acting in the vacuum accumulator. The pressure acting in the vacuum accumulator is computed from a mass balance of the mass flows supplied to the vacuum accumulator and withdrawn from the vacuum accumulator.

Abstract: An internal combustion engine having an intake passage that is closed at the time of engine starting operation wherein a holding time for completely closing a throttle valve is made as long as possible within such a range that the engine does not fail to be started. The throttle valve is held at its full-closure position when an ignition switch is turned on. Then, at the time of engine starting operation, an amount of air consumed by the engine is calculated based on a cumulative rotational speed of the engine, a cylinder volume of the engine, and a parameter of volumetric efficiency corresponding to an engine rotational speed, and, if so, the throttle valve is opened to a predetermined opening degree.

Abstract: An electronic throttle control apparatus is provided with an electronic throttle (1) including a throttle valve (4) which is opened and closed by a motor (5), and a microcomputer (11) which controls the motor (5). The microcomputer (11) calculates a deviation between a target opening degree which is set by detection of an accelerator sensor (5) and an actual opening degree which is detected by a throttle sensor (6) to calculate a motor control amount in accordance with the deviation and a control gain in correspondence to the deviation. The microcomputer 11 sets a control gain which becomes smaller as the deviation becomes larger, and limits the control gain by the previous control gain at a time when the control gain is larger than the previous control gain. The microcomputer (11) cancels the limit of the control gain when the calculated actual opening degree change is reduced from a predetermined value.

Abstract: A load adjustment apparatus for a final control element (4) which determines the power of an internal combustion engine and is arranged on an actuating shaft (2) has a torsion spring (18) which is stressed by a minimum-load gear between a minimum-load position and an emergency-running position and is stressed by an actuating gear (5) between a full-load position and the emergency-running position. The minimum-load gear has a dog (10) which can be pivoted in the same sense as a gearwheel (9) arranged on an intermediate gearwheel (8) and serves to take along one end (12) of the torsion spring (18), the end resting against a stop (13) in the emergency-running position. The torsion spring (18) loads the actuating part (4) and hence the actuating shaft (2) continuously into the emergency-running position.

Abstract: An engine control unit and method of controlling the operation of a gas fuelled internal combustion engine of the kind having a gas injector for injecting gaseous fuel into each cylinder and an inlet manifold through which air flows into each cylinder of the engine, the inlet manifold having a manifold valve to control the flow of air into the inlet manifold. An improved control strategy employed by the engine control unit involves closed loop control of airflow through the inlet manifold of the engine. Manifold absolute pressure (MAP) (70) and manifold air temperature (MAT) (72) are employed to calculate air density (84) which is representative of the mass of air flowing through the inlet manifold (28). The detected air density (84) is compared to a desired air density (DAD) (86) and an air density correction (88) is calculated to adjust the manifold valve position (MVP) (90).

Abstract: A throttle valve control apparatus of an engine is constructed so that the poorer the response of the throttle valve, the larger the value of a control signal given as a control signal for opening of the throttle valve, whereby the speediness of control and response of the throttle valve are improved. The engine throttle valve control apparatus has means for comparing a target opening which is a control target of the throttle valve and a real opening which obtained by a sensor or the like, and obtaining a corrected target opening of the throttle valve by a map or computing, corresponding to a difference obtained as the result of the comparison.
