Abstract: The disclosure discloses a transmission system capable of implementing four-wheel drive and an operating model thereof. The transmission system includes an odd shift motor, an even shift motor, a front-wheel drive shaft, a rear-wheel drive shaft, a front-wheel output shaft gear disposed on the front-wheel drive shaft, and a rear-wheel output shaft gear disposed on the rear-wheel drive shaft. The front-wheel output shaft gear and the rear-wheel output shaft gear are connected by a front/rear drive shaft coupling sleeve. In the disclosure, coordinated control of two motors allows the motors to operate with high efficiency to the maximum, which improves the efficiency of the transmission system. A four-wheel drive model and a two-wheel drive model are implemented through the coordinated control of two motors. Moreover, in the disclosure, sensor information is used to synchronously control a rotational speed during gear shift, which can reduce the impact during the gear shift.

Abstract: The present invention relates to a particulate filter, which comprises —a substrate, comprising a plurality of porous walls extending longitudinally to form a plurality of parallel channels extending from an inlet end to an outlet end, wherein a quantity of the channels are inlet channels that are open at the inlet end and closed at the outlet end, and a quantity of channels are outlet channels that are closed at the inlet end and open at the outlet end; and —a layer of inorganic particles loaded on surfaces of the porous walls in the inlet channels and/or outlet channels, preferably in at least the inlet channels, wherein the inorganic particles have a D90 in the range of 5.0 to 14.0 microns.
