摘要： Die Erfindung betrifft Verfahren zum Betreiben einer Verbrennungskraftmaschine, insbesondere eines Kraftfahrzeuges, bei dem Kraftstoff in einen Brennraum eines von mehreren betrachteten Zylindern (Z n ) in Abhängigkeit eines vorgebbaren Sollwinkels (phi soll ) eines rotierenden Bauteils der Verbrennungskraftmaschine, der mit dem Kurbelwinkel (KW) einer Kurbelwelle der Verbrennungskraftmaschine korrespondiert, zu einem Zeitpunkt (t soll ) gezündet und/oder eingespritzt wird, wobei ein Zünd- und/oder Einspritz-Zeitpunkt (t soll ) zu einem spätesten Festlegungs-Zeitpunkt (t vor ) unter Kenntnis über den Sollwinkel (phi vor ) und die aktuelle Drehzahl (U/min vor ) des einen der mehreren Zylinder (Z n ) zum Festlegungs-Zeitpunkt (t vor ) festgelegt wird.
Es ist vorgesehen, dass zu dem spätesten Festlegungs-Zeitpunkt (t vor ) entschieden wird, ob zwischen dem spätesten Festlegungs-Zeitpunkt (t vor ) und dem Zünd- und/oder Einspritz-Zeitpunkt (t soll ) eine nach dem spätesten Festlegungs-Zeitpunkt (t vor ) stattfindende Änderung der Drehzahl zu einer Verschiebung des Zünd- und/oder Einspritz-Zeitpunktes (t soll ) führt, indem eine Drehzahl (U/min vor-1 ) mindestens eines der mehreren Zylinder (Z n ), der in der zeitlichen Zündreihenfolge dem einen betrachteten Zylinder (Z n ) vorhergeht, zu einem vor dem spätesten Festlegungs-Zeitpunkt (t vor ) liegenden Zeitpunkt (t vor-1 ) überwacht wird, wobei das Überschreiten eines vorgebbaren Drehzahlgradienten (ΔU/min) zwischen den Zeitpunkten zwischen (t vor ) und (t vor-1 ) zu einer Aktivschaltung einer Schutzfunktion führt, bei der zumindest in Abhängigkeit des ermittelten Drehzahlgradienten (ΔU/min) eine Korrektur des ohne Aktivschaltung festgelegten Zünd- und/oder Einspritz-Zeitpunktes (t soll ) unter Festlegung eines korrigierten Zünd- und/oder Einspritz-Zeitpunktes (t soll ) erfolgt, sodass zu dem korrigierten Zünd- und/oder Einspritz-Zeitpunkt (t soll' ) trotz der Drehzahländerung der vorgegebene Sollwinkel (phi soll ) beibehalten wird.

摘要： A control device for an engine 1 including four cylinders, and configured to perform a reduced-cylinder operation by idling some (first and fourth cylinders) of four cylinders. The control device includes a hydraulic valve-stopping mechanism 14b which closes the intake and exhaust valves 41, 51 of the first and the fourth cylinders in response to establishment of the reduced-cylinder operation execution condition, a hydraulic variable valve timing mechanism 19 capable of changing a phase of the exhaust valve 51 of the engine 1, and an ECU 110 which controls the valve-stopping mechanism 14b and the hydraulic variable valve timing mechanism 19. In response to establishment of the reduced-cylinder operation execution condition, the ECU 110 allows the hydraulic variable valve timing mechanism 19 to execute the phase change to the exhaust valve 51, and subsequently allows the valve-stopping mechanism 14b to bring the intake and exhaust valves 41, 51 of the first and the fourth cylinders into closed states.

摘要： A compression-ignition engine control system is provided, which includes an intake variable mechanism and a controller. Within a first operating range and a second operating range on a higher engine load side, the controller controls the variable mechanism to form a gas-fuel ratio (G/F) lean environment in which an air-fuel ratio inside a cylinder is near a stoichiometric air-fuel ratio and burnt gas remains inside the cylinder, and controls a spark plug to spark-ignite mixture gas inside the cylinder to combust in a partial compression-ignition combustion. The controller controls the variable mechanism to advance the intake valve open timing on an advancing side of a TDC of the exhaust stroke, as the engine load increases within the first range, and retard the intake valve open timing on the advancing side of the TDC of the exhaust stroke, as the engine load increases within the second range.

摘要： A control device for an engine in which partial compression-ignition combustion including spark ignition combustion performed by combusting a portion of mixture gas inside a cylinder by spark ignition followed by compression ignition combustion performed by causing the rest of the mixture gas inside the cylinder to self-ignite is executed within at least a part of an operating range of the engine, is provided. The device includes a detector configured to detect a parameter related to noise caused by the combustion inside the cylinder, and a combustion controller configured to control the combustion inside the cylinder during the partial compression-ignition combustion based on the detected parameter of the detector and a reference value defined as an upper limit regarding the noise. The reference value is adapted to increase as a vehicle speed, an engine speed, and/or an engine load increases.

摘要： A control apparatus for an internal combustion engine is provided that can precisely reflect requirements relating to performance of the internal combustion engine in a control amount of each actuator by compensating for weaknesses in the so-called torque demand control. A requirement value of each of torque, efficiency, and an air-fuel ratio, and engine information are inputted to an engine inverse model 30. The engine inverse model 30 is then used to calculate actuator requirement values for achieving those requirement values. An actuator direct requirement value directly required of each of actuators 2, 4, and 6 is also acquired. Control of the actuators 2, 4, and 6 is adapted to be changed between that according to the actuator requirement value and that according to the actuator direct requirement value.

摘要： A hand-held power tool comprising an internal combustion engine (4), a working tool (6), a centrifugal clutch (8), and a control system (10) is disclosed. The engine (4) has a clutch-in speed, above which the engine (4) drives the working tool (6). The control system (10) comprises a rotation speed sensor (12), and a speed limitation controller (14), which is configured to limit an engine speed at a limitation speed below the clutch-in speed. It is active or activated during a starting procedure of the internal combustion engine (4). The control system (10) is configured to deactivate the speed limitation controller (14) upon sensing at least one acceleration at a level above the limitation speed and sensing at least one deceleration at a level above the limitation speed, such that the engine (4) is rotatable above the limitation speed to drive the working tool (6).
