Engine Dynamic Load Leveling
First Claim
1. A method for controlling an internal combustion engine having a plurality of cylinders using electronic valve actuation, comprising:
- operating a first portion of the cylinders in a homogeneous charge compression ignition (HCCI) mode;
operating a second portion of the cylinders in a non-HCCI mode; and
adjusting the valve timing of the second portion of cylinders to dynamically load level the engine in response to a transient torque demand.

Abstract
A method for controlling an internal combustion engine having a plurality of cylinders using electronic valve actuation, including operating a first portion of the cylinders in a homogeneous charge compression ignition (HCCI) mode, operating a second portion of the cylinders in a non-HCCI mode, and adjusting the valve timing of the second portion of cylinders to dynamically load level the engine in response to a transient torque demand. A system for controlling a multiple cylinder internal combustion engine, including a first group of cylinders to operate in an HCCI mode, a second group of cylinders to operate in a non-HCCI mode, and an engine controller operably coupled to the first and second groups of cylinders, said controller to adjust the valve timing of the second group of cylinders to dynamically load level the engine in response to a transient torque demand.
