  • Method for extending HCCI load range using a two-stroke cycle and variable valve actuation
    Patent number: 7231892
    Abstract: A method and system for extending the load range of Homogeneous Charge Compression Ignition (HCCI) in an internal combustion engine includes detecting a current state of the engine, detecting a load demand placed on the engine, determining if the load demand is beyond a power generating capacity of a four-stroke engine cycle based on the current state of the engine and the load demand, and switching from the four-stroke engine cycle mode to a two-stroke engine cycle mode when it is determined that the load demand is beyond the capacity of the four-stroke engine cycle.
