Abstract: An internal combustion engine is configured to satisfy the relation expressed by 0<Rv<0.000438×?2?0.0407×?+1.55 in a range of an intake valve overlap amount ?(°) from 20° to 45°, where Rv denotes an intake port volume ratio obtained by dividing an intake port internal volume Vp by a cylinder stroke volume Vc, and the intake valve overlap amount ?(°) is a crank angle from an intake valve opening timing when the intake valve starts opening to an intake top dead center of the piston. The engine improves output performance as well as both combustion performance and emission performance by suppressing reverse flow of the combustion gas into the intake system.

Abstract: The press device includes a press device body and moving bolsters. The press device body has a slide and a slide servomotor. The slide has upper dies attached thereto. The slide servomotor moves the slide up and down. The moving bolsters are able to move between a pressing position, which is a position on the inside of the press device body, and a die replacement position, which is a position on the outside of the press device body, and have lower dies disposed thereon.
