Integrated air induction module for gasoline engines

An engine air intake module comprising:

• a walled air box comprising a dirty air space within which a tubular particulate filter that has radially inner and radially outer faces is disposed such that an imaginary centerline of the filter is generally horizontal and the radially inner face circumferentially surrounds a clean air space;
• a dirty air inlet for delivering dirty air into the dirty air space of the air box;
• a clean air outlet for delivering clean air from the clean air space;
• a throttle body assembly comprising an inlet into which clean air from the clean air outlet enters and an outlet from which clean air exits;
• a plenum comprising an inlet at which clean air from the throttle body assembly outlet enters a plenum space;
• and
• runners that have respective inlets through which clean air from the plenum space enters and that have respective lengths running along respective center lines from the respective inlets to respective outlets for delivering clean air to respective cylinders of an engine;
• and
• in which each respective imaginary vertical plane that passes through a respective runner centerline at the respective runner outlet intersects the centerline of the tubular filter at a vertical elevation below that of the respective runner centerline at the respective runner outlet.

An engine air intake module comprising:

• an air box comprising first and second walled parts enclosing an interior that contains a particulate filter through which air flow through the air box is constrained to pass, thereby separating a clean air space from a dirty air space;
• the first and second walled parts comprising respective closed perimeters which bound respective openings of the respective parts and form a joint at which the parts fit together;
• one of the parts comprising a divider wall that divides an interior volume of the one part into a portion of one of the air spaces and a portion of the other of the air spaces, including dividing the opening of the one part into two respective open areas each bounded by its own closed perimeter;
• the other part comprising and interior volume and a divider that divides the opening of the other part into two respective open areas each bounded by its own closed perimeter;
• an element captured between the first and second walled parts comprising a closed perimeter frame captured between the closed perimeter frames of the parts to make the joint between the parts air-tight;
• the element comprising a divider that divides the frame into two respective open areas each bounded by its own closed perimeter and that is captured between the divider of the other part and the divider wall of the one part such that a first of the open areas of the one part, of the other part, and of the element are disposed in mutual registration, and a second of the open areas of the one part, of the other part, and of the element are disposed in mutual registration, with the closed perimeter bounding the first open area of the element being captured between the closed perimeter frames bounding the first open areas of the first and second parts to make an air-tight joint between them, and with the closed perimeter bounding the second open area of the element being captured between the closed perimeter frames bounding the second open areas of the first and second parts to make an air-tight joint between them;
• and one of the open areas of the element containing the particulate filter.
