摘要： A method is provided for controlling regeneration of an SCR catalyst. The method includes coordinating the regeneration duration and temperature (e.g., longer/shorter regenerations and/or lower/higher temperatures) to the urea deposit loading. In this way, improved regeneration may be achieved due to the particular nature of urea deposits on SCR catalysts.

摘要： A method and system for controlling combustion mode in an internal combustion engine is disclosed. A method for controlling a multi-cylinder internal combustion engine includes operating a portion of the cylinders according to a first combustion mode and operating a second portion of the cylinders according to a second, different combustion mode. The net torque produced by the cylinders equals driver demanded torque. By this invention, a first combustion mode, which has a desirable combustion characteristic such as high fuel economy or low emissions, but which cannot provide driver demanded torque if used in all cylinders, can be used in combination with a second combustion mode, thereby meeting driver demand for torque and gleaning the benefits of the first combustion mode.
