Patent number: 7121255Abstract: A compression ignition engine (60) has a control system (66) for processing data, one or more combustion chambers (62), and fuel injectors (64) for injecting fuel into the chambers. The control system controls fueling by processing engine speed and load, to select one of four fueling modes (HCCI+RVT, HCCI+IVC, HCCI+IVC+EVC, and CD+RVT) for operating the engine (FIG. 5). When HCCI+RVT mode is selected, intake valves operate with regular valve timing (RVT), and the engine is fueled to cause homogeneous-charge compression-ignition (HCCI) combustion. When HCCI+IVC mode or HCCI+IVC+EVC mode is selected, intake valve timing is changed relative to RVT, and the engine is fueled to cause HCCI combustion. When the processing selects the CD+RVT mode, the intake valves operate with RVT, and the engine is fueled to cause CD combustion. In HCCI+IVC+EVC mode, exhaust valve closing is retarded relative to its timing in HCCI+IVC mode to reduce cylinder pressure and temperature.Type: GrantFiled: May 31, 2005Date of Patent: October 17, 2006Assignee: International Engine Intellectual Property Company, LLCInventors: Zhengbai Liu, Puning Wei, Dennis Kelly Sullivan

Patent number: 6248041Abstract: A linkage between an engine control (114) and vehicle controls, such as a transmission gear selector (100) and/or axle speed selector when the vehicle has a two-speed axle, providing input to the engine control that is additional to engine variable inputs (110) for tailoring engine performance characteristics to selected drive ratios of a drivetrain through which the engine drives the vehicle. The tailored characteristics include particular engine torque curves (FIGS. 1, 4, and 5) and particular engine speed regulation curves (FIGS. 1, 2, and 3). As the vehicle quickly accelerates through rated engine speed while the transmission in the lower gears, the driver's notices no feeling of abrupt shut-off. As the vehicle accelerates through the highest gears toward highway speed, the driver can feel sustained pulling effort by the engine.Type: GrantFiled: July 13, 1999Date of Patent: June 19, 2001Assignee: Navistar International Transportation Corp.Inventor: John A.

Patent number: 6173622Abstract: A shift tower housing for a vehicle transmission that can receive either a push button selector or a lever selector at a comfortable and ergonomic location. The surfaces of both the push button and the lever selectors are at about 15% to the horizontal, which renders surface indicia on the selectors in a comfortable vision range for the operator. The inclined upper surfaces of the selectors also places lever and push buttons at comfortable ergonomic position for the operator. Replacing a single mounting part can make a conversion from a push button selector unit to a push button selector unit. The shift tower also includes mounting mechanism upon which a stand-alone electronic control unit is mounted, that is compatible with either the push button selector or the lever selector control. The vibrations of the shift tower are minimized as a result of mounting it directly to vehicle floor support member.Type: GrantFiled: April 15, 1999Date of Patent: January 16, 2001Assignee: Navistar International TransportationInventors: Gregory S.
