Publication number: 20140260189Abstract: An internal combustion engine forced induction system and a method for operating the same. The turbocharged engine has an electronic control module and operating instructions in memory. The system includes a modified forced induction system that captures and stores air from the induction system via a system of valves and releases the stored air back into the intake system during acceleration so that turbo response lag is reduced or greatly ameliorated. Regenerative braking is further disclosed to capture and store air for release to the intake system. A method for controlling the forced induction system is also disclosed. Furthermore, a method for controlling the exhaust flow away from the exhaust stream upstream of the turbocharger and into an auxiliary storage tank and back into the exhaust stream upstream of the turbocharger; assisting the pre-spool of the turbine to further or also reduce turbo response lag.Type: ApplicationFiled: March 14, 2014Publication date: September 18, 2014Applicant: Desen CorporationInventors: Darryl Sendrea, Joseph M. Jenkins

Patent number: 7624973Abstract: A shock absorber assembly includes a coil spring that reacts between first and second spring seats. The first spring seat is fixed to a shock cylinder and the second spring seat is fixed to a rod that is slidably received within the shock cylinder. An isolator is positioned between an end coil of the spring and at least one of the first and second spring seats. The isolator comprises an annular ring that defines a cavity that is at least partially filled with fluid. The isolator evenly distributes non-centered spring end forces through the fluid to reduce the effects of side load forces.Type: GrantFiled: December 12, 2005Date of Patent: December 1, 2009Assignee: ArvinMeritor Technology, LLCInventors: Joseph A. Fader, Mark Christopher Smith, Paul Kurt Miska, Muhammad Salim, Stephen Heagle, Darryl Sendrea, Nathan Clark, Evan Moen

Patent number: 7320387Abstract: A shock absorber for a vehicle suspension includes a pneumatic actuator that is fluidly connected to a compressed air source in the vehicle suspension, such as a suspension air bag. The pneumatic actuator cooperates with an adjustment mechanism housed within the shock absorber to adjust damping. The shock absorber includes a main rod that supports a piston for axial movement within a cylinder body. The piston separates the cylinder body into first and second fluid chambers. The adjustment mechanism includes an adjustment rod that is received within an axial bore formed within the main rod. The adjustment rod is axially moved within the axial bore by the pneumatic actuator to uncover and cover a plurality of bores that are in fluid communication with at least one of the first and second fluid chambers. The pneumatic actuator includes a plunger having a tapered surface that engages the adjuster rod to move the adjuster rod in a desired direction to adjust damping.Type: GrantFiled: April 6, 2005Date of Patent: January 22, 2008Assignee: ArvinMeritor Technology, LLCInventor: Darryl Sendrea

Publication number: 20070158925Abstract: A shock absorber assembly includes a coil spring that reacts between first and second spring seats. The first spring seat is fixed to a shock cylinder and the second spring support is fixed to a rod that is slidably received within the shock cylinder. At least one of the first and second spring seats comprises an adjustable two-pierce spring seat. First and second spring seat pieces are initially movable relative to each other to achieve a desired spring pierce point location for a selected operational position. Once the first and second spring seat pieces are adjusted to a desired position, the first and second spring seat pieces are permanently attached to each other.Type: ApplicationFiled: January 6, 2006Publication date: July 12, 2007Inventors: Joseph Fader, Mark Smith, Paul Miska, Muhammad Salim, Stephen Heagle, Darryl Sendrea, Nathan Clark, Evan Moen

Patent number: 7150450Abstract: An air spring suspension damper assembly includes a first housing and a second housing which telescope relative to each other. An actuating member such as a cable is connected to a height leveling valve contained in one of the housings and attached to the other housing. The actuating member moves a member such as a rotating cam, a rotating valve plate and/or a rotating valve such that changes in the suspension height rotate the member. Rotation of the member selectively opens inlet and exhaust flow paths to control the air pressure in the damper assembly and maintain air suspension height at a predetermined height.Type: GrantFiled: June 4, 2003Date of Patent: December 19, 2006Assignee: ArvinMeritor Technology, LLCInventors: Stephen Howard Bell, Darryl Sendrea

Patent number: 6659241Abstract: An adjustable shock absorber is provided that includes a body having a fluid passageway with first and second passages in fluid communication with one another. A valve assembly is arranged between the passages and includes a plunger that is adjustable between a plurality of positions corresponding to a plurality of fluid flow positions. The valve assembly includes a metering valve having a orifice in a disc, and the plunger includes a needle with a portion disposed in said orifice to provide flow area. The flow area is changed when the plunger moves. The valve assembly also includes a blow-off valve in which the disc is biased to a closed position by a spring arranged between the plunger and the disc. Movement of the plunger changes the loading on the spring. An adjustment knob has a cammed surface that cooperates with the plunger so that as the adjustment knob is rotated the cammed surface moves the plunger.Type: GrantFiled: August 22, 2001Date of Patent: December 9, 2003Assignee: Meritor Heavy Vehicle Technology, LLCInventor: Darryl Sendrea

Patent number: 6648109Abstract: A shock absorber assembly includes a damping adjustment mechanism that can easily be incorporated into a twin cylinder design. The shock absorber includes an outer cylinder and an inner cylinder mounted within the outer cylinder. The inner cylinder is spaced apart from the outer cylinder to define a gap. A piston is mounted within a fluid filled chamber formed within the inner cylinder to dampen vibrations. Holes are drilled into the wall of the inner cylinder to provide fluid ports that can communicate with the gap to form a bi-directional fluid path as the piston moves back and forth within the chamber to dampen vibrations. To provide variable damping, the outer cylinder includes an eccentric inner diameter to outer diameter profile that allows damping adjustment between high and low damping forces. The damping force is adjusted by rotating the outer cylinder relative to the inner cylinder to vary the size of the gap with respect to the ports.Type: GrantFiled: September 13, 2001Date of Patent: November 18, 2003Assignee: Meritor Heavy Vehicle Technology, LLCInventors: Neil Farr, Darryl Sendrea

Publication number: 20030051954Abstract: A shock absorber assembly includes a damping mechanism that adjusts to compensate for operation at elevated temperatures. A member made of two dissimilar materials permanently bonded together with one material having a higher expansion coefficient than the other material provides a biased response toward the material with the lower expansion coefficient. This biased response compensates for incremental pressure changes in the shock absorber due to operation at elevated temperatures to provide constant damping regardless of temperature.Type: ApplicationFiled: September 18, 2001Publication date: March 20, 2003Inventor: Darryl Sendrea
