FIELD: car industry.
SUBSTANCE: invention relates to a method for restoring a particulate filter in the exhaust duct of a car having a hybrid drive of an electric engine and an internal combustion engine. The internal combustion engine is spun by an electric engine to restore the particulate filter. The internal combustion engine pumps oxygen-rich air into the exhaust duct, while the soot trapped in the particulate filter can be oxidized with oxygen, and the particulate filter can be restored. The amount of air during the restoration of the particulate filter is controlled by the throttle valve on the air supply of the internal combustion engine to make it possible to restore the particulate filter as quickly and efficiently as possible. The invention also concerns a car having a hybrid drive of an internal combustion engine and an electric engine, while the hybrid drive has a control device for performing such a method of restoring the particulate filter.
EFFECT: technical result is an increase in the speed and efficiency of the restoration of the particulate filter, which reduces the phase of forced idling of the electric engine.
