    摘要: 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).

    摘要: A control system for operating vanes of a turbocharger turbine (16T) and for operating a turbine-shunting bypass valve (22) according to a strategy wherein a processor executes an algorithm for selectively unenabling the control system to operate the bypass valve when the control system is operating the vanes to adjust exhaust back-pressure on the engine within a range of effectiveness for the vanes to control the exhaust back-pressure and enabling the control system to operate the bypass valve when the control system has operated the mechanism to a limit of the range of effectiveness.

    摘要: 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.
