The method assists in the rapid design of emissions component installations by: interpreting a tube design input which may be an exhaust pipe with one or more aftertreatment components, calculating a final tube design and tube drawing, determining the manufacturability of the final tube design, determining the manufacturing cost of the final tube design, and displaying the drawing, manufacturability result, and manufacturing cost to a user. The method also evaluates the final tube design for portions that can be replaced with a more cost effective alternative. The method also receives the emissions reduction features of the installation from the user, and recommends secondary components to mitigate operational consequences, such as reduced fuel economy or reduced oil change intervals, of the emissions reduction features.Type: ApplicationFiled: December 29, 2006Publication date: July 3, 2008Inventors: John W. Clevenger, Donald A. Gibson, David Sarcona, Michael J. Senetar

Patent number: 7383912Abstract: An exhaust pipe structure has, under a floor of a vehicle, an exhaust passage for exhaust gas discharged from a vehicle-installed engine, and at least one muffler is provided on an intermediate portion of the exhaust passage. The at least one muffler includes a main muffler having the greatest muffler capacity. An external cylinder forming an outer shell portion of the main muffler has a circular sectional shape having a diameter of 100 mm to 150 mm, or a sectional shape that is substantially equal to an area of the circular sectional shape. The external cylinder has a length of 800 mm to 12000 mm. The main muffler is disposed in a tunnel portion that is formed between the front wheels and the rear wheels.Type: GrantFiled: October 9, 2003Date of Patent: June 10, 2008Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tadashi Kondo, Junichi Yamaguchi, Yohika Arimura, legal representative, Katsuro Arimura

Publication number: 20080121451Abstract: A hood assembly for a machine includes an enclosure within which at least one exhaust aftertreatment device is mounted. The engine hood assembly may be preassembled so that the exhaust aftertreatment system is integrated into the enclosure. This may allow the hood assembly to be assembled to the machine and the exhaust aftertreatment system mated to an exhaust pipe from the engine as a unit while the machine is being built on an assembly line. The engine hood assembly may include ventilation openings to assist in heat rejection from the engine compartment and from the exhaust aftertreatment devices. The hood assembly of the present disclosure finds particular application in assisting large track type tractors in meeting ever more stringent exhaust emission requirements without extensive and expensive redesign alternatives.Type: ApplicationFiled: November 28, 2006Publication date: May 29, 2008Inventors: Tony G. Kertz, Christopher M. Brian

Patent number: 7367417Abstract: An off-road vehicle has a frame with a floorboard extending laterally over a middle region of the frame. The floorboard has a upward projection that defines a tunnel. At least a portion of an air intake system of an engine of the vehicle is positioned within the tunnel. A foot pedal is disposed in front of a seat such that a driver of the vehicle can operate the pedal by foot. The tunnel has a surface that is laterally adjacent the foot pedal such that the foot of a driver can simultaneously contact the surface and the foot pedal.Type: GrantFiled: March 2, 2004Date of Patent: May 6, 2008Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Akira Inui, Norihiko Tanaka

Patent number: 7364002Abstract: At the underside of a vehicle body, a fuel tank and an exhaust muffler are disposed alongside of each other along a vehicle body longitudinal direction, with a drive shaft being disposed between the fuel tank and the exhaust muffler. The front and rear of the fuel tank are attached with tank bands to two cross members. The exhaust muffler is attached to the two cross members via rubber supports. Because the exhaust muffler and the fuel tank are attached to common cross members, the noise vibration characteristics of the vehicle body are improved while suppressing an increase in the weight of the vehicle body.Type: GrantFiled: February 2, 2005Date of Patent: April 29, 2008Assignee: Toyota Jidosha Kabushiki KaishaInventors: Tomoki Mabuchi, Koji Mineda, Takashi Ishikawa
