Abstract: One embodiment is a system comprising an engine including a dedicated EGR cylinder configured to provide EGR to the engine via an EGR loop, a non-dedicated cylinder, a plurality of injectors, an ignition system including a plurality of spark plugs, an intake throttle, and an electronic control system. The electronic control system is configured to control combustion during transient operation of the engine by determining one or more combustion control parameters compensating for variation of one or more of inert matter, unburned air and unburned fuel in EGR output by the dedicated EGR cylinder during transient operation of the engine, and an effect of the EGR loop on inert matter, unburned air and unburned fuel provided to the plurality of cylinders, and controlling operation of at least one of the throttle, the ignition system and the plurality of injectors in response to at least one of the one or more combustion control parameters.

Abstract: A method, system, and apparatus use infrared spectrometry onboard an internal combustion engine running on a natural gas fuel to detect characteristics of the fuel. At a site having a plurality of natural gas engines, detection of natural gas fuel components and concentrations of the components also is conducted at the site upstream of the point of intake of the natural gas fuel to one or more of the engines. Operating parameters of the engine or a plurality of the engines may be controlled on the basis of the detected composition of the natural gas fuel.

Abstract: A series or range extender hybrid vehicle drive system is disclosed having a combustion engine with an exhaust aftertreatment device, a motor/generator, an electrical energy storage and a traction motor. The traction motor is driven using power from the energy storage and/or the engine. A controller of the system is operable to receive input data representative of a requested power from the drive system, a state of charge indication of the electrical energy storage and at least one of the oxygen level in exhaust gas from the engine and temperature in the exhaust gas. The controller is also operable to provide output signals to control torque and speed of the engine and motor/generator to minimize exhaust emissions output and any tracking error of the state of charge of the energy storage to a desired target.
