Abstract: This paper develops a model for the idle speed control of a six cylinder electronically fuel injected, spark ignition engine. The inherently discrete microprocessor based fuel controller is not ...

Abstract: A control-oriented engine model is developed to represent a spark ignited engine equipped with a variable cam timing mechanism over a wide range of operating conditions. Based upon laboratory ...

Abstract: The 2004 Federal Tier II and California LEV I emission standards for diesel light trucks mandate tailpipe NOx levels of 0.6g∕mi. Active lean NOx catalysts (ALNC or LNC) have been proposed as ...

Abstract: A model-based control scheme is designed to regulate the cylinder air charge of a camless multicylinder engine for unthrottled operation. The controller consists of a feedforward and an adaptive ...

Abstract: The improvement of internal combustion engine is largely accomplished though the introduction of innovative actuators that allow optimization and control of the flow, mixing, and combustion ...

Abstract: Actuation schemes exist that permit the joint management of air and fuel flow into the cylinders of a spark ignition engine. With the exception of drive by wire systems, to-date, the transient ...
