Abstract: A gasket (201) includes one or more elastomeric sections (301, 305, 307) disposed on a metal substrate (303). An elastomeric ring (307) has an inner diameter (309) that is smaller than an outer diameter of a fastener (205). When the fastener (205) is inserted into the ring (307), the fastener (205) and gasket (201) are retained to each other. When a flange (101) for a device, such as an oil pick-up tube (100), is disposed between the fastener (205) and the gasket (201), the gasket (201) and fastener (205) are retained to the flange (101).

Abstract: In a conventional diesel combustion mode, one or more cylinders (12) of an engine (10) is or are fueled to cause conventional diesel combustion in each such cylinder. The resulting exhaust gas is treated by a diesel particulate filter (36) in an exhaust system (34) before exiting the exhaust system. In an alternative diesel combustion mode, such as HCCI, one or more cylinders of the engine are fueled to create in each such cylinder an in-cylinder fuel-air charge that ignites by auto-ignition as the charge is increasingly compressed. Also a bypass valve (38) is opened so that the resulting exhaust gas bypasses the DPF as the exhaust gas passes through the exhaust system.

Abstract: A clamp (26) has a main body (30) that is attached to an engine block (28). A right-angled flange (32) extends from the main body to enter a downwardly open concave interior of an outturned flange (18) of an oil pan rim (16) and provides underlying support for an insert (46) on which the outturned flange of the oil pan rim rests. Fretting of the rim is avoided because the presence of the insert avoids any substantial contact between the flange (32) and the rim (16) that could lead to fretting.

Abstract: A reinforcing plate (405) is utilized with a lightweight hub (101) in a vibration damper. Holes (105) formed in the hub (101) and the reinforcing plate (405) allow the vibration damper to be mounted to a shaft with a stronger joint than when the reinforcing plate (405) is not utilized, thereby preventing deformation of the hub (101). Optional reduction holes (111) formed in the hub (101) provide for additional weight reduction, vibration reduction, and/or noise reduction.

Abstract: A PI control strategy controls engine speed to an engine speed set-point. A proportional map (36) is populated with data values to be used in calculating the P component of the strategy. An integral map (38) is populated with data values to be used in calculating the I component. Each data value in the maps is correlated with a speed data value representing engine speed (N) and a speed error data value representing the difference between engine speed and engine speed set-point (N_DIF_MAX_LIM). Values for proportional and integral components are selected from the respective maps by processing current engine speed data and current engine speed error data. The strategy uses the values from the maps for controlling engine speed to the speed set-point. Data values from other maps (20 and 24; or 22 and 26) modify the selected values from the proportional and integral maps (36, 38) for transmission type, transmission gear, and engine temperature.

Abstract: Testing of temperature sensors (28, 30, 32) in an emission control system, such as in an exhaust system (10) of a diesel engine, serves to condition further component and/or system testing by determining that sufficient sensor cooling has occurred and that no sensor is “stuck within range” using a strategy (50).

Abstract: A method for enabling initiation of regeneration of a NOx adsorber catalyst. While the engine is operating to propel the vehicle, data indicative of NOx adsorption efficiency of the NOx adsorber catalyst, data indicative of temperature of exhaust gas passing through the NOx adsorber catalyst, data indicative of speed of the motor vehicle, and data indicative of engine fueling are processed according to an algorithm (10) that will enable regeneration to be initiated upon concurrence of the data indicative of NOx adsorption efficiency indicating an efficiency less than a defined efficiency, of the data indicative of temperature of exhaust gas passing through the NOx adsorber catalyst indicating a temperature suitable for initiating regeneration, of the data indicative of speed of the motor vehicle indicating vehicle speed suitable for initiating regeneration, and of the data indicative of engine torque indicating engine torque suitable for initiating regeneration.

Abstract: A method for regenerating a diesel particulate filter (20) in the exhaust system (16) of an engine (12). When a request to regenerate the device is issued, a control system (14) operates the engine to begin conditioning exhaust. The conditioning process comprises a warming phase that occurs prior to initiation of regeneration and a heating phase during which regeneration can occur. During the process, data related to the warming phase and the heating phase is evaluated. The engine is operated to terminate the process prior to having reduced the amount of trapped particulate matter to a target amount when evaluation of the data discloses that the process should be terminated.
