摘要:
A diagnostic system and method for a gasoline particulate filter (GPF) of an exhaust system of a vehicle comprise at least one heater associated with at least one oxygen (O2) sensor disposed proximate to the GPF in the exhaust system and a controller configured to determine a status of the GPF based on a duty cycle of the at least one O2 sensor heater and, based on the determined status of the GPF, detect a malfunction of the GPF or whether to regenerate the GPF.
摘要:
The embodiments of the present application provide an image processing method, an image processing apparatus, and an electronic device. The image processing method includes: generating an image of an object by shooting the object with an image generation element; acquiring information of a shooter when the object is shot; and merging the information of the shooter into the image of the object to generate an image having the information of the shooter and information of the object. Through the embodiments of the present application, not only the information of the shooter and the object can be acquired, but also repetitive operations such as the user authentication can be reduced, thereby achieving better user experience.
摘要:
An exhaust gas flow concentration system for a catalyst includes an inlet that receives a flow of exhaust gas from an exhaust pipe of an exhaust system, a stationary tube in communication with the inlet and disposed upstream from the catalyst, and an extension tube in communication with the stationary tube and disposed upstream from the catalyst, where the extension tube includes a cross-sectional area less than a cross-sectional area of the catalyst. A displacement device is coupled to the extension tube and is configured to (i) displace the extension tube relative to the stationary tube downstream towards the catalyst as a temperature in the exhaust system decreases away from a light-off temperature of the catalyst and (ii) retract the extension tube relative to the stationary tube upstream away from the catalyst when the temperature in the exhaust system reaches the light-off temperature of the catalyst.
