摘要： Embodiments for controlling boost pressure are provided. In one example, a method of controlling a turbocharger of an engine via a multi-staged wastegate comprises during a first condition, actuating a first stage of the wastegate based on boost pressure generated by the turbocharger, and actuating a second stage of the wastegate based on a temperature of a catalyst downstream of the turbocharger. In this way, catalyst heating and boost control may be provided by a common wastegate.

摘要： A method to supply fuel to an engine of a vehicle is provided. The method includes adjusting a direct injection of fuel into a cylinder of the engine based on whether the vehicle is in a pre-delivery state. In one example, the method includes reducing an amount of fuel in a post injection to reduce cylinder bore wetting effects and lubricant dilution during the engine cold start. After pre-delivery, a normal post injection schedule may be used to reduce emissions.

摘要： A motor-vehicle engine system comprises a first DOC configured to receive exhaust from an engine and an SCR device coupled downstream of the first DOC in a flow direction of the exhaust. The system further comprises a second DOC coupled downstream of the SCR device. The system takes advantage of hydrocarbon sorption in the SCR catalyst that is a function of temperature to enable reduced hydrocarbon emissions via oxidation at the second DOC.

摘要： A system for effective NOx and particulate matter control in a diesel or other lean burn internal combustion engine is presented. The system includes a urea-based SCR catalyst having an oxidation catalyst coupled upstream of it and a particulate filter coupled downstream of the SCR catalyst. This system configuration results in improved NOx conversion due to fast SCR catalyst warm-up and higher operating temperatures. Additionally, placing the particulate filter last in this system configuration reduces tailpipe ammonia emissions as well as prevents any thermal damage to the SCR catalyst due to the particulate filter regeneration.
