摘要： If operation mode of an engine is transitioned from natural aspiration lean-burn operation mode to supercharged lean-burn operation mode, an engine control portion temporarily changes an air-fuel ratio from a lean air-fuel ratio to a stoichiometric air-fuel ratio or a rich air-fuel ratio. When the air-fuel ratio is changed from the lean air-fuel ratio to the stoichiometric air-fuel ratio or the rich air-fuel ratio by the engine control portion, a transmission control portion switches a gear ratio of the automatic transmission to a gear ratio that provides an engine rotational speed at which the engine output becomes equal to an engine output before the air-fuel ratio is changed and also at which an intake pipe pressure becomes equal to or closest to an intake pipe pressure before the air-fuel ratio is changed.

摘要： The invention relates to a method for protecting a DPF in the exhaust section of an internal combustion engine of a motor vehicle from unintentional combustion of soot in the DPF. According to the invention, the motor vehicle is a hybrid vehicle having at least one electric machine and is able to be driven exclusively by one or more electric machine(s) for some time. The vehicle is operated in a DPF protection mode if the system detects that unintentional combustion of soot is taking place or threatening to take place in the DPF, initiating an automatic decoupling of the combustion engine from the wheel drive train, forward propulsion demands by the driver are met exclusively with the aid of the one or more electric machine(s), and the combustion engine is switched off completely or is operated with stable stoichiometric combustion.

摘要： A method for selecting an engine operating point in a multi-mode powertrain system includes monitoring a desired axle torque based on an operator torque request and vehicle speed. For each available combustion mode of the diesel engine, engine torque and speed ranges are received and a plurality of fuel losses and a plurality of emissions losses are retrieved, each fuel and emissions loss corresponding to respective ones of a plurality of engine operating points within the engine torque and speed ranges. The respective fuel and emissions losses are compared at each of a plurality of potential engine operating points within the engine torque and speed ranges of the available combustion modes. A desired engine operating point within one of the available combustion modes is selected that corresponds to one of the potential engine operating points having a lowest power loss based on the compared respective fuel and emissions losses.

摘要： A method is applied to regenerate particulate matter in a particulate filter of a hybrid electric vehicle having a combination of a combustion engine and an electric motor for propelling the vehicle, the hybrid electric vehicle having an electrically heated catalyst disposed in flow communication with the particulate filter in an exhaust system of the vehicle. The method determines whether the combustion engine is or is not combusting fuel, and under a condition where the combustion engine is not combusting fuel, the catalyst is electrically heated until it has reached a temperature suitable to cause ignition of the particulate matter. The electric motor is used to facilitate rotation of the combustion engine at a rotational speed suitable to draw air into and be exhausted out of the combustion engine into the exhaust system, across the catalyst, and into the particulate filter to facilitate ignition of the particulate in the filter.

摘要： A hybrid vehicle includes an engine and a motor each for generating vehicle driving power. An operation region indicated by rotational speed and torque of the engine includes: an normal region in which a fuel injection amount is calculated in accordance with a stoichiometric air-fuel ratio; and an amount increase region in which an amount of fuel is increased compared with the normal position so as to suppress temperature increase of a catalyst. A control device calculates a total required power of the vehicle depending on the vehicle state, and determines an engine operation point in accordance with the total required power. When the engine operation point is in the OT amount increase region, the engine operation point is changed to fall within the normal region by decreasing the engine output power. An output power of the motor is determined to compensate the decrease of the engine output power and secure the total required power.

摘要： A hybrid vehicle executes intermittent operation for stopping an operation of an internal combustion engine and thereafter resuming the operation in response to an operating state. An air-fuel ratio control apparatus executes air-fuel ratio feedback control for bringing an air-fuel ratio of air-fuel mixture supplied to the engine on the basis of an output of an upstream air-fuel ratio sensor and an output of a downstream air-fuel ratio sensor into coincidence with a target air-fuel ratio. The air-fuel ratio control apparatus acquires a catalyst parameter that indicates a state of the catalyst at a start of the engine through intermittent operation. The air-fuel ratio control apparatus substantially corrects the target air-fuel ratio in response to the acquired catalyst parameter in a predetermined period after a start of the engine through intermittent operation, and learns a sub-feedback amount that is calculated using the output of the downstream air-fuel ratio sensor.
