Title: AIR INTAKE DEVICE FOR ENGINES
Abstract:
An air intake device (1) for engines includes an air cleaner (4) and an air flow sensor (6). The air cleaner (4) is provided with: an air filter (28); a cleaner case (12) having formed therein a primary space (S1) and a secondary space (S2), which are located above and below the air filter (28); an inlet duct (16) for introducing air into the primary space (S1); and an outlet duct (20) for delivering air from the secondary space (S2). The air flow sensor (6) is affixed to the outlet duct (20). The cleaner case (4) includes a first side wall (13a) to which the inlet duct (16) is provided, and a second side wall (13b) which faces the first side wall (13a). The air filter (28) has a corrugated folded shape and is held by the cleaner case (4) such that the folds extend in the direction perpendicular to the direction in which the first side wall (13a) and the second side wall (13b) are arranged. The second side wall (13b) has a deflection section (18) for deflecting an air flow, which is introduced from the inlet duct (16), in the obliquely upward direction.
