摘要:
A control method including regulating air pressure prevailing in an engine intake manifold around a setpoint value. The regulating includes a slow regulation loop, a fast regulating loop, and a limitation of pressure upstream of a turbine of a supercharger. The supercharging pressure limitation is implemented when the pressure upstream of the turbine exceeds a predetermined threshold value.

An engine control, and in particular a method for controlling an engine including a low-pressure exhaust gas recycling loop. The method adjusts a predetermined engine operating parameter by controlling the position of an exhaust gas recycling valve, which is placed in the loop, for determining whether the predetermined measured quantity of the valve respects a predetermined criteria, and controls the position of an exhaust shutter, which is arranged outside the loop, when the quantity does not respect the criteria.
摘要:
A method for controlling an internal combustion engine that includes a booster system including a turbocharger, an exhaust gas recirculation system including a recirculation valve and an electronic control unit for controlling geometrical configuration of the turbocharger and the recirculation valve of the recirculation system. The method detects variation of an acceleration command of the internal combustion engine when the booster system operates according to a first controlled operating mode, switches the booster system to a transitory operating mode according to the detected variation, wherein the turbocharger is maintained in a given geometrical configuration for a predetermined time, and switches the booster system to a second controlled operation mode.
摘要:
The invention relates to a method for controlling an internal combustion engine (1) which comprises a booster system provided with a turbocharger (6, 8), an exhaust gas recirculation system (12) provided with a recirculation valve (13) and an electronic control unit (14) for controlling the geometrical configuration of the turbocharger (6, 8) and the recirculation valve (13) of the recirculation system. The inventive method consists in detecting the variation of the acceleration command of the internal combustion engine (1), when the booster system operates according to a first controlled operating mode (BF, BF′), in switching the booster system to a transitory operating mode (BO2, BO2′) according to the detected variation, wherein the turbocharger (6, 8) is maintained in a given geometrical configuration for a predetermined time, and in switching the booster system to a second controlled operation mode (BO1, BO1′).
