Patent Images
1. A control system for an engine, comprising:
- one or more actuators for controlling one or more inputs to an engine;
a controller coupled to the one or more actuators, the controller including a multi-parameter model that models the effects of changes in the one or more actuators on each of two or more engine operating parameters; and
wherein the controller is configured to adjust at least one actuator of the engine and make a change to one or more inputs to the engine in order to produce a controlled change in each of the two or more engine operating parameters as modeled by the multi-parameter model.

Abstract
A system for controlling fuel to an engine to minimize emissions in an exhaust of the engine. There may be a controller connected to an actuator, for example a fuel control actuator, of the engine and to emissions sensors, such as an NOx and/or PM sensor, proximate to an exhaust output of the engine. The controller, for example a speed controller, may have an input connected to an output of a pedal or desired speed setting mechanism. A speed sensor at a power output of the engine may be connected to an input of the controller.

13. An engine control system comprising:
-
one or more actuators for controlling one or more inputs to an engine; a controller coupled to one or more of the actuators, the controller controlling the fuel profile that is delivered to the engine; an emissions sensor connected to the controller, the emission sensor for sensing an emission parameter of the engine; wherein the controller includes a multi-parameter model that models the effects of changes in the one or more actuators on each of two or more engine operating parameters including the emission parameter; and wherein the controller is configured to adjust at least one actuator of the engine, including a fuel actuator, in order to produce a controlled change in each of the two or more engine operating parameters including the emission parameter, as modeled by the multi-parameter model. - View Dependent Claims (14, 15, 16, 17, 18, 19)
