Abstract
An air cleaner chamber is configured such that a filtering member is held between an air cleaner cover and an air cleaner case. A low-speed operation air intake passage and a high-speed operation air intake passage share an outlet passage portion near a dusty space, and are molded integrally on the air cleaner case using a synthetic resin. A passage switching valve is disposed so as to switch an aperture area of the high-speed operation air intake passage. In addition, a valve actuator for driving the passage switching valve is mounted to the air cleaner case.
Claims7
An engine air intake apparatus comprising:
- a plurality of air intake passages molded integrally on a synthetic resin air cleaner case of an engine air cleaner;
- a passage switching valve disposed on said air cleaner case, said passage switching valve switching among said plurality of air intake passages;
- and
- a valve actuator for driving said passage switching valve,
- wherein:
- each air intake passage of said plurality of air intake passages is formed so as to have a passage portion shared with at least one other of said air intake passages, and
- said valve actuator drives said passage switching valve so as to selectively switch among said plurality of air intake passages so as to configure an air intake pathway corresponding to an engine operating state.
