  • Publication number: 20180298870
    Abstract: A system for controlling one or more conditions associated with combustion events in one or more cylinders of an engine while generally maintaining a spark timing value at a relatively constant value. The system includes a controller configured to determine one or more temporary adjustments to the spark timing value that brings one or more conditions, such as, for example, engine knock levels and/or NOx levels to around, or within, a corresponding target or threshold level(s). Following selection and implementation of one of the adjustments to the spark timing value, the controller implement adjustments to the adjusted spark timing value to return to a target spark timing value. The controller can further be adapted to determine adjustments to the air-to-fuel ratio to accommodate operation of the engine at the target spark timing value while maintaining the one or more conditions at or below the corresponding threshold or target level(s).

  • Patent number: 9702289
    Abstract: A waste heat recovery (WHR) system operates in a reverse mode, permitting using the WHR system to transfer heat to the exhaust gas of an internal combustion engine. In another configuration, a WHR system may operate in two modes. The first mode removes heat from exhaust gas of an engine to perform useful work. The second mode transfers heat to the exhaust gas. The benefit of this flexible system is that a WHR system is adaptable to rapidly heat exhaust gas at startup and during other conditions where the temperature of the exhaust gas is less than a predetermined operating range. Because of the ability to rapidly warm engine exhaust gas, an exhaust gas receiving system, such as an EGR or an aftertreatment system, may function to reduce the emissions of the engine more quickly. Because this system is reversible, it retains the capability of a conventional WHR system.

  • Patent number: 9683507
    Abstract: A system includes an internal combustion ignition engine with an exhaust gas flow, a particulate filter in the exhaust gas flow, a NOx reduction catalyst in the exhaust gas flow downstream of the particulate filter, a first oxygen sensor coupled to the exhaust gas flow downstream of the NOx reduction catalyst, and a second oxygen sensor coupled to the exhaust gas flow between the particulate filter and the NOx reduction catalyst. A controller includes an exhaust conditions module that interprets a first oxygen signal from the first oxygen sensor and a second oxygen signal from the second oxygen sensor and a combustion control module that commands a high engine-out air-fuel ratio when the first oxygen signal indicates a low oxygen content and commands a low engine-out air-fuel ratio when the first oxygen signal indicates a high oxygen content.
