<P>PROBLEM TO BE SOLVED: To provide a supercharging device with a supercharging assist and an emission adjusting valve, capable of adjusting an amount of air to be introduced into a combustion chamber. <P>SOLUTION: The supercharging device includes: a low-pressure turbocharger 806; a backflow prevention valve 807 that shuts an intake pipe 803 in an upstream side during assisting supercharging; a pressure accumulation tank 808 accumulating compressed air; an emission adjusting valve 101 that is hydraulically driven to close or open, does not emit the compressed air in the pressure accumulation tank 808 during closing and emits the compressed air in the pressure accumulation tank 808 to a compressor 805 during opening, and reduces the opening rate of the valve when the inner pressure of an intake manifold 804 increases; and a drive air pipe 102 introducing air from the intake manifold 804 to the emission adjusting valve 101. <P>COPYRIGHT: (C)2012,JPO&INPIT |
