Abstract: A diesel engine (100) has a control system (102) that processes certain data to develop data values for one or more temperature-dependent variables, such as injection control pressure (ICP), that affect engine starting and ensuing warm-up. The control system also processes data for detecting a temperature differential in the engine indicative of a block heater (126) having been used to heat the engine prior to cranking. Upon detection of such temperature differential, the control system selects a temperature data source from multiple available temperature data sources, namely engine coolant temperature ECT, engine oil temperature EOT, and charge air temperature AIT, and processes temperature data from the selected source with additional data to develop data values for one or more of the temperature-dependent variables.

Abstract: A signal is received (201, 301) via a wireless communication channel, which signal requests initiation of pre-cycle warm-up for one or more components of an internal combustion engine. It is determined (203, 303) whether at least one of the one or more components requires pre-cycle warm-up. When at least one of the one or more engine components requires pre-cycle warm-up, the at least one of the one or more components is warmed up (205, 207, 305, 307).

Abstract: An engine (10) and a method of operating it during cold start and ensuing running using a cold start aid such as a glow plug control (24) and glow plugs (22). The control (24) monitors all glow plugs to distinguish between one that is effective and one that is ineffective. When a glow plug is disclosed to be ineffective, the engine control system (14) reduces the quantity of fuel introduced into the respective combustion chamber (12) in comparison to the quantity of fuel that would be introduced were the respective glow plug effective. This is beneficial in keeping the collection of hydrocarbons of surfaces of a diesel particulate filter (20) from increasing due to an ineffective glow plug.

The seal (301) also has a third surface capable of contacting a sensor (201) disposed in a second fluid, while a fourth surface, opposed to the third surface, is capable of contacting the seal seat (303). The seal (301) is capable of separating the first fluid from the second fluid while preventing the first fluid and the second fluid from leaking out of the valve cover (101).

Abstract: An internal combustion engine (30) has a fueling system comprising fuel injectors (36) that utilize oil under pressure to force fuel into engine combustion chambers. Oil is pumped to an oil rail (44) by an engine-driven pump (42) whose effective displacement can be varied. A control system (32) processes certain data, such as engine speed and load, for controlling the effective displacement of the pump. The pump has a larger stage (42B) and a smaller stage (42A). The control system selects and de-selects the stages to control pump displacement.

Abstract: An engine (10) has a fueling system that uses hydraulic fluid to force fuel into engine combustion chambers via fuel injectors. Pressure of the hydraulic fluid is determined by a steady state strategy (ICP_DES—1) and a transient strategy (34, 36) that develops transient data values to account for certain transients in engine operation by processing engine speed data and data representing rate of change of engine speed, and data representing engine fueling to develop sub-strategy data values (ICP_FF_TS, ICP_FF_TL) for a transient component. The data values ICP_DES—1, ICP_FF_TS, and ICP_FF_TL are algebraically summed to develop a data value (ICP_DES—2) for a transient-modified desired hydraulic fluid pressure that is compared with a data value for actual hydraulic fluid pressure (ICP) to develop a data value for an error signal ICP_ERR. The data value for the error signal is processed according to a closed-loop strategy to develop a data value that controls the hydraulic fluid pressure.

Abstract: A motor vehicle engine (10) has a glow plug system (14) for aiding combustion of fuel in combustion chambers of the engine when the engine is cold and an ignition switch (16) is operated to crank the engine. A first circuit signals the cold start aid to commence operation of the cold start aid in anticipation of engine starting. A second circuit indicates a fault in the cold start aid. A third circuit, that includes a warning signal device (38), activates the warning signal device to inform a driver of the vehicle of the indicated fault upon the first circuit having signaled the cold start aid to commence operation and the second circuit having indicated a fault in the cold start aid.

Abstract: A diesel engine (10) operates by alternative diesel combustion. Formation of fuel and charge air mixtures is controlled by processing a particular set of values for certain input data according to a predictor algorithm model (50) to develop data values for predicted time of auto-ignition and resulting torque, and also develop data values for control of fuel and air that will produce the predicted time of auto-ignition and resulting torque. The data values developed by the predictor algorithm and data values for at least some of the input data are processed according to a control algorithm (52) that compensates for any disturbance introduced into any of the data values for at least some of the input data being processed by the control algorithm. This causes the systems to be controlled by compensated data values that produce predicted time of auto-ignition and resulting torque in the presence of any such disturbance.

Abstract: An engine (10, 100) utilizes “regular EGR cooling” when operating in HCCI mode within a low load range and “enhanced EGR cooling” that allows the engine to continue to operate in HCCI mode when engine load increases beyond the low load range. When engine load increases to a high load range, the combustion mode changes over to conventional diesel combustion, and exhaust gas recirculation reverts to “regular EGR cooling”. In a first embodiment, cooling is provided by two heat exchangers, one being a regular EGR cooler always used when cooling is needed and the other, an enhancing EGR cooler that is selectively used. In a second embodiment, cooling is also provided by two heat exchangers, one being an EGR cooler through which liquid coolant always flows when cooling is needed, and the other being a radiator used selectively to cool the liquid coolant before it enters the EGR cooler.

Abstract: A compression ignition engine (10) has a control system (24) for processing data, one or more cylinders (16), a fueling system (18), and a variable valve actuation mechanism (20). Control system (24) develops both fueling data for fueling the engine and timing data representing time during the engine cycle for intake valve closure to a cylinder that will endow the cylinder with an effective compression ratio (ECR) appropriate to current engine operation for causing auto-ignition to occur near or at top dead center in the engine cycle. During a compression upstroke, the cylinder is fueled according to the fueling data and intake valve closure for the cylinder is performed according to the timing data. This creates an air-fuel mixture that is increasingly compressed to the point of auto-ignition near or at top dead center.

Improved engine performance on vehicle launch and reduced emissions result.

Abstract: A vortex mixing system mixes intake air with exhaust gases for exhaust gas recirculation (EGR) in an internal combustion engine. The vortex mixing system may have a vortex mixing device connected to an intake air conduit, a supply conduit, and an EGR conduit. The vortex mixing device may have a plenum disposed around a mixing conduit, which is connected to the intake air conduit and the supply conduit. The plenum is connected to one or more cross conduits and to the EGR conduit. The cross conduits extend across a mixing chamber formed by the mixing conduit. The cross conduits generate one or more vortices in the intake air. Each cross conduit has one or more outlets. The cross conduits direct the exhaust gases through the outlets into the vortices. The exhaust gases mix with the intake air in the vortices.
