Abstract: The invention proposes a switchable support element (1) requiring only a small design space. For this purpose, a slide (12) that serves to couple an inner element (6) to an outer housing (3) in the support element (1) is positioned laterally in a housing (2) arranged in the cylinder head (5). At the same time, a bore (8) in the inner element (6) for the slide (12) is made as a pocket bore, the housing (2) being seated through an annular extension (11) directly in a bore (9) of the outer housing (3). The slide (12) can be displaced electromagnetically or hydraulically in at least one direction.

Abstract: An electronic arrangement for controlling gas exchange valves of an internal combustion engine with variable valve control is presented. The valve control makes possible to completely hold closed at least the inlet valves and the electronic arrangement is equipped with means for detecting the air quantity, which is inducted by the engine, and with means for detecting the valve stroke. The electronic control arrangement changes the opening function in overrun operation starting from the fully closed inlet valves so that an opening of the inlet valves takes place and the arrangement detects the index of the valve opening at which a reaction of the air quantity detection takes place and uses this index as a reference point for determining the actual opening cross section.

Abstract: In an engine 3, the phase of an intake camshaft 6 and/or an exhaust camshaft 7 for opening and closing intake valves 4 and/or exhaust valves 5 can be changed relative to a crankshaft 9, and NOx produced during lean-burn operation is occluded by a NOx occlusion catalyst 14. An ECU 2 of a control device 1 increases the amount of fuel such that an air-fuel ratio A/F used during the lean-burn operation is enriched by an enrichment amount R1, to thereby purge the NOx occlusion catalyst of NOx occluded therein and controls to change the phase CAIN of the intake camshaft 6 towards the advance side relative to the crankshaft 9.

Abstract: A combustion control system for a diesel engine provided with a fuel injection system and a sensor for detecting an ignition timing. The combustion control system comprises a control unit which is configured to control the ignition timing to be restored to a target value when the ignition timing shifts from the target value owing to circumferential factors such as cetane number of fuel. Preferably, the ignition timing is controlled to generally coincide with or be retarded relative to a fuel injection termination timing. This regulates an ignition delay period to be longer than a fuel injection period in a predetermined engine operating region, thereby effectively accomplishing so-called low temperature premix combustion.

Abstract: A system and method for unthrottled intake air control for an internal combustion engine. The engine has at least one combustion chamber provided with electromagnetic intake means. The opening and closing times of the intake means are adjustable entirely independently from the crankshaft position to control intake air supplied to the combustion chamber. A control unit is used to implement instructions for determining a first portion of requested intake airflow, which first portion requests a first engine response performance, and instructions for determining a second portion of requested intake airflow, which second portion requests a second engine response performance. The control unit implements instructions for processing the first and second airflow portions to make contributions to the first and second engine response performances, respectively, instructions for determining an intake means activation command, and instructions for providing the intake means activation command to the intake means to provide an engine response performance combining the first engine response performance with the second engine response performance.

Abstract: A control system for an internal combustion engine is configured to suitably control the operation of electromagnetically driven intake valves and/or exhaust valves upon start-up of the engine for reducing the output current of a battery and suppressing a reduction in output voltage at minimum, thereby accurately operating the electromagnetically driven valves. The control system is operated such that when an ignition switch is turned on, the operation of a starter is prohibited and initial attraction for intake valves and exhaust valves is sequentially performed in such a manner that the attracting operations for the valves are not overlapped to each other; and after the initial attraction for all the valves is completed, the operation of the starter is permitted and the start-up of the engine is performed.
