A method and apparatus for continually and rapidly adjusting the output torque of an engine according to a torque demand uses an active tappet to vary the instant air charge in a combustion chamber, so as to modulate engine torque during an automatic change of speed ratio. The invention allows substantially efficient combustion throughout the engine operating map. Various methods of changing the charge of air are disclosed.

At least an embodiment may provide a remote server that can predict overheating of an engine. A remote server may receives an engine rotational speed, an engine load factor, and a cooling-water temperature. The remote server calculates a moving average of the engine load factor during a predetermine time, and calculates a correlation between the moving average of the engine load factor and the cooling-water temperature. If the correlation during a predetermined period is in the status of a predetermined difference from the correlation up to the predetermined period, the remote server predicts occurrence of overheating in a swing working vehicle that is used by a user.

Described is a method for controlling an internal combustion engine, wherein an ignition control device is prompted by control signals of an engine control device to activate an ignition device by means of which an ignition of a fuel-air mixture in a cylinder of the internal combustion engine is affected. It is provided according to this disclosure, that the engine control device communicates a target ignition angle or information about an operating condition of the internal combustion engine to the ignition control device, and the ignition control device sets an operating parameter of the ignition device in dependence on the target ignition angle or the information about the operating condition of the internal combustion engine.

A method and apparatus to determine values for at least one fuel use characteristic variable which represents a first fuel use process in a first vehicle, are provided. In addition, values are determined for at least one parameter which represents at least one peripheral condition of the fuel use in the first vehicle during the first fuel supply process. A mathematical relationship is determined between one or more supplied values of the at least one fuel use characteristic variable and the corresponding values of the at least one parameter. A profile data record including a data record and/or learning data is supplied on the basis of at least one determined mathematical relationship. At least one further fuel parameter of a fuel which is used by the first vehicle and/or by a second vehicle during a second fuel use process is adapted as a function of the supplied profile data record.

A misfire detecting system for an engine of a vehicle that detects a misfire of the engine is provided. The system includes a sensor configured to detect a wheel speed of the vehicle, a load adjustment device configured to adjust a load of the engine, and a processor. The processor determines whether a wheel slip has occurred by examining whether a change rate of the wheel speed is equal to or greater than a determination reference value, when determining whether the wheel slip has occurred, limits a determination of the misfire of the engine by adjusting the determination reference value higher or lower based on corresponding increases or decreases in a requested load, by applying the adjusted determination reference value, determines that wheel slip has occurred, and based on the wheel slip determination, determines that the misfire has occurred.
