    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 (1). The system comprises an electrically driven pressure charging device (10) and an electronic control system (32) for controlling the operation of the pressure charging device (10). The electronic control system (32) calculates a desired air charge according to engine torque demand (120), and calculates one or more allowable operating limits to the operation of the pressure charging device (10) based on at least one operating parameter (110,122,125) of the air charge boosting system. The engine control system (32) then drives the pressure charging device (10) responsive to the desired air charge and within the calculated allowable operating limit.

    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 (1). The system comprises an electrically driven supercharger (10), an electronically controlled throttle (17) for controlling engine aspiration, and an electronic control system (ECU) (32) for controlling engine operation. The ECU (32) sets the throttle (17) position to regulate the aspiration of the engine (1), and calculates at least one desired aspiration parameter according to engine torque demand (120). The ECU then determines at least one actual aspiration parameter (122,125) according to engine operating conditions (22,25), and compares (63) the desired aspiration parameter(s) (62) with the actual aspiration parameter(s) (122,125). The ECU drives (114) the supercharger (10) to boost aspiration of the engine (1) in accordance with the comparison between the desired aspiration parameter(s) and the actual aspiration parameter(s) only when the torque demand (120) cannot be met by natural aspiration alone.

    摘要: The present invention relates to an internal combustion engine having a catalytic converter to reduce exhaust gas emissions. The engine (2) comprises one or more internal combustion chambers (4), an air supply system (20) for aspirating the combustion chambers, an exhaust gas system (19) for carrying away exhaust gas (10) from the combustion chambers (4), and a secondary air supply system (60) between the air supply system (20) and the exhaust gas system (19). The exhaust gas system (19) includes a catalytic converter (17) for reducing engine emissions, and the air supply system (20) includes an electrically driven pressure charging device (18) for pressurising air supplied (6) to the combustion chambers (4). The secondary air supply system (60) provides a path for air pressurised by the pressure charging device (18) to flow (68) from the air supply system (20) downstream of the pressure charging device (18) to the exhaust gas system (19) upstream of the catalytic converter (17) in order to facilitate catalyst light off.

    摘要: The present invention relates to a crank case ventilation system for an internal combustion engine that has a two-stage air charge boosting system. An air inlet system (5) supplies the engine (2) with air (8) that may be pressurised by an upstream supercharger (18) and a downstream turbocharger (20) in series. A crank case evacuation system (40) draws crank case gasses (42) from a crank case (6) and introduces said gasses (42) into the air inlet system (5), through either a first conduit (48) or a second conduit (50), depending on the setting of a pressure-regulated control valve (46). The first conduit (48) is used to introduce said gasses (42) upstream of the first boost stage (18) when this stage is operational, and when the first boost stage (18) is not operational, the second conduit (50) is used to introduce said gasses (42) downstream of the first boost stage (18) and upstream of the second boost stage (20).
