Abstract:
1. A method for starting an internal combustion engine having a motor mechanically coupled to the engine, the engine having at least one moveable element mounted in a chamber, the moveable element being operable to cause a changing compression condition within the chamber as the moveable element moves from a low compression condition through a compression stroke to a peak compression condition, the engine being mechanically coupled to a shaft for generating mechanical power, the method comprising: calculating a reference positioning torque; causing the motor to supply the reference positioning torque to the engine to move the at least one moveable element in a direction opposite to a direction of the compression stroke into a starting position where the positioning torque is opposed by a compression condition due to a firing stroke of the engine; and causing the motor to supply a starting torque to the engine.
