Abstract: An integrated analytical model assesses the ability and fitness of a field worker to take on critical plant jobs or tasks. The inputs to the model include data about the worker's level of experience, competency, physical condition, workload, medical history, stress level as well as a live feed of health data obtained from devices worn by the worker. This data is fed into a machine learning model to assess the worker's ability to conduct work as well as the risk level to people or equipment or operations, serving as a tool to protect workers and assets. The model also provides root causes analysis for not assigning the task to the worker and recommends corrective actions.

Abstract: In response to activation of a compression release brake when a motor vehicle having a turbocharged internal combustion engine is operating at some elevation above sea level and a turbocharger compressor is operating in a region of an operating map which is creating boost air in an engine intake manifold which would cause the compression release brake to decelerate the vehicle more slowly at that elevation than it would at sea level for the same operating conditions of the vehicle and engine other than altitude, the compression release brake decelerates the vehicle less slowly by causing an exhaust gas recirculation system to reduce at least one of a) mass of exhaust diverted to an intake system of the engine and b) cooling of the diverted exhaust.

Abstract: A heat exchanger having a modified header design for absorbing high thermal loads, is described. The heat exchanger includes a housing having an interior space, a core within the interior space of the housing, the core comprising a plurality of flow passages, and a header positioned at an end of the housing and in communication with the core, wherein the header includes a thermal absorbing formation. The thermal absorbing formation may take the form of a continuous raised rib around an inner circumference of the header. The raised rib absorbs excess heat and reduces thermal strain on the heat exchanger.

Abstract: A system for driving an EGR stream for an engine includes an exhaust gas turbine, a main compressor and a supplemental EGR compressor. The turbine drives the main compressor to pressurize intake air and drives the supplemental EGR compressor to pressurize an EGR exhaust gas stream to be introduced into the intake air system. A supplemental EGR compressor takes suction of exhaust gas downstream from the turbine. A three-way valve proportions exhaust gas between the engine exhaust gas discharge conduit and the suction of the supplemental EGR compressor. The turbine drives a shaft and the main compressor and the supplemental EGR compressor are driven by having corresponding compressor wheels fixed onto the common shaft.

Abstract: A first loop contains engine coolant passageways (28, 30) and a first radiator (34). A second loop contains a first EGR cooler (48). A third loop contains a second EGR cooler (50), a second radiator (36), a charge air cooler (26LP), a first valve (66), and a second valve (64). Valve (64) apportions coolant flow entering an inlet (64A) to parallel flow paths, one including second radiator (36) and the other being a bypass around radiator (36). The apportioned flows merge into confluent flow to both an inlet of charge air cooler (26LP) and a first inlet (66B) of valve (66). Valve (66) has an outlet (66C) communicated to an inlet of second EGR cooler (50). The first condition of valve (66) closes a second inlet (66A) to coolant flowing toward both the second inlet (66A) and inlet (64A) while opening inlet (66B) to outlet (66C).

Abstract: Unique to this invention is the design of an Exhaust Gas Recirculation (EGR) valve with bypass capabilities. EGR valves combined with a bypass valve are expensive to design and manufacture due to their complexity and unique differences. Furthermore, the reliability of multiple components is much lower than that of the single component. During various engine operating conditions it is necessary to divert the flow of exhaust gas around the EGR cooler through the intake manifold or through the EGR cooler to lower the temperature of the exhaust gas to reduce noxious emissions. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A circuit for cooling exhaust gas being recirculated through an EGR system (36) of an engine (10) from an exhaust system (20) successively through first and second heat exchangers (38, 40) to an intake system (16) for entrainment with intake air. Each heat exchanger has a respective coolant inlet through which liquid coolant enters and a respective coolant outlet through which liquid coolant exits after having absorbed heat from recirculated exhaust gas. The circuit has a third heat exchanger (32) to which coolant coming from the outlet of one of the first and second heat exchangers rejects heat, and parallel branches (84, 86) through which coolant enters the inlet of the other of the first and second heat exchangers. One of the parallel branches has a fourth heat exchanger (34) to which coolant flowing through that branch rejects heat, and one or more devices (50, 50A) for controlling the quantity of coolant flowing through each branch.

Abstract: A system for driving an EGR stream for an engine includes an exhaust gas turbine, a main compressor and a supplemental EGR compressor. The turbine drives the main compressor to pressurize intake air and drives the supplemental EGR compressor to pressurize an EGR exhaust gas stream to be introduced into the intake air system. A supplemental EGR compressor takes suction of exhaust gas downstream from the turbine. A three-way valve proportions exhaust gas between the engine exhaust gas discharge conduit and the suction of the supplemental EGR compressor. The turbine drives a shaft and the main compressor and the supplemental EGR compressor are driven by having corresponding compressor wheels fixed onto the common shaft.

Abstract: A method of cooling exhaust gas (F) from an engine in an EGR cooler (10) for recirculation to the engine includes the steps of transporting the exhaust gas from the engine to a core assembly (22) disposed inside a single housing assembly (20), and dividing the housing assembly into at least a first cooling volume (42) of the EGR cooler (10) and a second cooling volume (44) of the EGR cooler (10). The core assembly (22) extends at least partially into the first cooling volume (42) and the second cooling volume (44).

The exhaust gas (F) is transported from the core assembly (22) to the engine.
