Abstract
A machine such as an external combustion engine in an electrical power and heat cogeneration unit comprises multiple cylinders, each driving an independent load or being independently driven, and a balance shaft comprising one or more off-center balancing mass(es) to counteract rocking motion created by the piston motion and thereby assist in dynamically balancing the machine.
