Abstract
A system and methods for operating four in-line cylinders with common rail injection is described that comprises operating a first cylinder group without a compression and power stroke injection, but with an exhaust stroke injection while operating a second cylinder group with at least a compression stroke injection. In this way, the unburned fuel injected during the exhaust stroke enriches the exhaust-gas flow and further allows heating of the exhaust aftertreatment system. In one example provided, the first cylinder group is further configured to operate in an exhaust heating mode while also operating in a power generating mode.
