METHOD FOR CONTROLLING WORKING CHARACTERISTIC OF INTERNAL COMBUSTION ENGINE AT NON-OPERATION OF ENGINE

摘要

PROBLEM TO BE SOLVED: To rapidly change sure engine operational characteristics and save the power consumption for the operation required for the change by reasonably changing the characteristics by an engine operational characteristic changing means, in changing the characteristics at non-operation of an engine in such a way that the intake compression ratio is increased before the cranking when the engine is in a cold state. SOLUTION: Displacement of the means to a predetermined position is carried out by the control of drive force (the intensity of the driving force and its operational time).
