摘要： The present invention relates to apparatus for scheduling the ignition sparks for a spark ignition internal combustion engine. An ignition system for a spark ignition engine, includes a device for generating a series of pulses (12) upon each revolution of a crankshaft (1) and a device (8,118) for identifying pulses in the series relative to a top dead center position (TDC) for the engine, one or more ignition coils and a device to charge a coil and then to discharge the coil to generate an ignition spark at a desired spark angle (54) relative to the top dead center position (TDC). The ignition system identifies a first particular pulse (60) occurring after the charging starts and before the discharging begins, and calculates a first interval (I.sub.D) from the first particular pulse (60) so that the discharging happens proximate the desired spark angle (54).

摘要： The present invention relates to an electronically driven pressure boosting system that is used to boost the torque output of an internal combustion engine. The system comprises an electrically driven pressure charging device, an electrical supply system for providing electrical power to drive the pressure charging device including a battery and an engine-driven battery recharger, and an electronic control system for controlling the operation of the pressure charging device and the electrical supply system. The electronic control system determines one or more allowable operating limits to the operation of the pressure charging device based on the state of the electrical supply system, and drives the pressure charging device using the engine-driven battery recharger when the state of the electrical supply system is within an acceptable range. The engine control system then isolates at least partially the battery from the engine-driven battery recharger and drive the pressure charging device using the battery when the state of the electrical supply system is not within an acceptable range.

摘要： The present invention relates to an apparatus (1) and a method for quantifying the net torque (28) produced by an internal combustion engine, for example, in a motor vehicle. Nominal gross engine torque (2) and expected torque losses (17,19,21) associated with the engine (102) are estimated. Estimated net torque (28) from the gross engine torque (2) and expected torque losses (17,19,21) are calculated. If it is determined that no power is drawn through the gearbox, a corrective torque loss value (21) corrects the estimated expected torque losses associated with the engine (102)
