An internal combustion engine incorporating a turbo-generator and one or more variably activated exhaust valves. The exhaust valves are adapted to variably release exhaust gases from a combustion cylinder during a combustion cycle to an exhaust system. The turbo-generator is adapted to receive exhaust gases from the exhaust system and rotationally harness energy therefrom to produce electrical power. A controller is adapted to command the exhaust valve to variably open in response to a desired output for the turbo-generator.

The invention claimed is: 1. An internal combustion engine comprising:a controllable exhaust valve variably releasing exhaust gases from an individual combustion cylinder during a combustion cycle to an exhaust system on a cycle to cycle basis;a turbo-generator receiving exhaust gases from the exhaust system and rotationally harnessing energy therefrom to produce electrical power; anda controller adapted to command the exhaust valve to variably open in response to a desired output for the turbo-generator, wherein the controller is adapted to open the exhaust valve progressively earlier in the combustion cycle when more turbo-generator output is desired, and to open the exhaust valve progressively later when less turbo-generator output is desired.
