Abstract: The disclosure concerns a method for vibration reduction in a compression ignition four- stroke internal combustion engine. The internal combustion engine comprises exhaust and intake valves controlled by exhaust and intake camshafts. The method comprises, when operating the internal combustion engine below a threshold rotational speed, steps of: changing a timing of the exhaust camshaft to advance closing of the exhaust valve, and - changing a timing of the intake camshaft to delay opening of the intake valve.

Abstract: Disclosed is a method, system, vehicle, and computer program for improving heat release evaluation at a reciprocating combustion engine. The method comprises providing a model regarding volume deviations in the combustion chamber based on a first set of dynamic parameters of the combustion engine. Said model comprises volume deviations due to thermal changes, due to mass forces and due to pressure forces. The method comprises determining the first set of dynamic parameters relating to the combustion engine, and determining the volume deviation in the combustion chamber based on said provided model and based on said first set of determined dynamic parameters. The method comprises providing an adaption model for the combustion engine based on said determined volume deviation in the combustion chamber, and adapting the combustion engine control and/or a diagnostic system of the combustion engine based on said adaption model so that said heat release evaluation is improved.

Abstract: A device and method for limiting peak current draw in an electronic device includes identifying an operational state of the electronic device, and accessing data stored in the electronic device, the data including possible operational states of the electronic device and respective configuration data for maintaining an electric current consumption of the electronic device below a prescribed threshold. Operational parameters of the electronic device are modified based on the data obtained from memory to maintain the electric current consumption of the electronic device below the prescribed threshold.
