METHOD FOR CONTROLLING STARTING CHARACTERISTIC CHANGING MEANS OF INTERNAL COMBUSTION ENGINE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To allow a starting characteristic changing means of an internal combustion engine for a vehicle having a piston working chamber for working a piston so as to reduce the intake compression ratio when a working fluid is introduced, and requiring the working fluid to be discharged from the piston working chamber when the intake compression ratio is increased to rapidly cope with the operation of increasing the intake compression ratio as required when starting the engine. SOLUTION: The working fluid in the piston working chamber is controlled to be discharged as the internal combustion engine is stopped. The working fluid may be discharged when or after the internal combustion engine is stopped.
