摘要： PROBLEM TO BE SOLVED: To make incineration treatment of a filter element unit possible by using a waste paper-mixed thermoplastic resin for making a filter material frame to be installed in the outer circumference of a filter material. SOLUTION: This air cleaner element 4 comprises a filter material 40 having a plurality of corrugated bag parts 400 and a filter material frame 404 having a flange part 12 formed in the outer circumferential rim 402 of the filter material 40. The filter material 40 is made of a nonwoven fabric and the filter material frame 404 is made of a waste paper-mixed thermoplastic resin. The corrugated bag parts 400 of the filter material 40 are constituted of a corrugated plate 406 and a side face plate 409 for closing apertures 408 in the side face of the corrugated plate 406. On the other hand, the filter material frame 404 is constituted of an outer circumferential wall part 403 surrounding the outer circumference and the flange part 12, and the wall part 403 and the flange part 12 are integrally formed by injection molding to reliably provide the rigidity of the whole body of the filter element 4.

摘要： PROBLEM TO BE SOLVED: To effectively utilize coupling of an air cleaner case with a resonator, and prevent deposition of dust on upper side parts of a split line between two mutually adjacent split outer shell parts. SOLUTION: An air cleaner case 5 is formed as an assembly of plural split shell parts 15, 16, and 17, and a filter 19 can be replaced when the split shell parts are separated from each other in this air cleaner 1 provided with the resonator 18. By installing the resonator 18 onto the split shell parts 15, 16, and 17 at plural positions, the split shell parts 15, 16, and 17 are coupled with each other.

摘要： PROBLEM TO BE SOLVED: To straighten a fluid which flows into a passage from a turbulent condition into a laminar flow condition, promote separation of the fluid in the vicinity of a wall surface, reduce frictional resistance and Reynolds stress, and improve a filling efficiency and an exhaust efficiency by forming a rough surface on a wall surface of an intake passage or an exhaust passage in an internal combustion engine. SOLUTION: In an engine 1, a laminar condition combustion is carried out at the time of a compression lean operating mode so as to improve a fuel consumption ratio. Namely, fuel is injected from a fuel injection valve 9 toward an ignition plug 10 at the time of a compression stroke, rich mixture is generated in the vicinity of the ignition plug 10, lean mixture is generated around the rich mixture, and then laminar mixture is generated. Inner walls of an intake port 5 and an exhaust port 6 in parts arranged adjacent to a combustion chamber 2 formed on a rough surface 13 by regularly arranging, for example, a recessed/projection part (a riblet). Accordingly, it is promoted that a fluid made of intake and exhaust which flows into each port 5, 6 is separated from the wall surface, and thereby, a frictional resistance is reduced. Also, it is promoted that the fluid which flows into each port 5, 6 is laminated.
