摘要： An alumina-based lean NOx trap system for use in a HCCI engine exhaust is provided which includes at least one alumina-based lean NOx trap comprising a catalyst, an alumina NOx absorbent material, and optionally, from 0 to about 4 wt % of an alkaline earth metal oxide; and a conventional three-way catalyst. The lean NOx trap system substantially oxidizes HC and CO and converts at least a portion of NOx contained in the exhaust gas to N2 at a temperature between about 150° C. to about 250° C. in HCCI mode. The system also effectively removes HC, CO and NOx at high temperature when the engine is in SI mode (stoichiometric conditions). The alumina-based lean NOx trap in the system also undergoes efficient desulphurization and maintains its activity with extended use.

摘要： Method and system embody a valve timing strategy to control the autoignition timing of a four stroke internal combustion engine (10) operated in an HCCI mode at different engine operating conditions such as different engine speed and torque. A particular valve timing strategy varies lift timing of the intake valve (20) relative to the exhaust valve (28), or vice versa, and relative to top dead center in response to a change in engine torque, for example, to vary amount of trapped residual burned gas in the combustion chamber (12) flowing to an intake or exhaust port (16,18) and back to the combustion chamber during which the residual gas is cooled. Control of the flow of residual gas between the combustion chamber and intake or exhaust port and thus its temperature by the valve timing strategy, in turn, is used to control the temperature of the fresh air/residual gas/fuel mixture in the combustion chamber (12) and thus autoignition timing in response to a change in engine torque.
