    摘要： An exhaust gas recirculation (EGR) system is provided for an internal combustion engine having a combustion air intake circuit and an exhaust circuit for communicating engine exhaust to the environment. The EGR system includes an air-to-gas EGR cooler, an air inlet line communicating cooling inlet air to the EGR cooler, an EGR supply line communicating exhaust from the exhaust circuit to the EGR cooler, a venturi unit in the exhaust circuit, and an air outlet line communicating heated air from the EGR cooler to the venturi unit. Flow of exhaust through the venturi creates a pressure which draws cooling air through the EGR cooler. The EGR system also includes a turbocharger unit having an exhaust turbine and an inlet air compressor. A compressor outlet circuit communicates air from the compressor to an air intake of the engine. A valve is located in the compressor outlet circuit. An EGR venturi is in the compressor outlet circuit and is connected in parallel with the valve. A cooled EGR line communicates cooled exhaust gas from the EGR cooler to a suction port of the EGR venturi.

    摘要： A vehicle engine cooling system includes a primary cooling circuit having a primary radiator and a coolant pump. A secondary cooling circuit includes a secondary radiator, an EGR cooler, and a liquid/air charge air pre-cooler receiving engine inlet air from a turbocharger compressor. The coolant pump circulates coolant through the EGR cooler, through the charge air pre-cooler, and through the primary and secondary radiators. A fan blows cooling air through the primary and secondary radiators. The secondary radiator is downstream of the primary radiator in the fan airflow. The cooling system also includes an air-to-air charge air cooler which receives engine inlet air from the liquid/air charge air pre-cooler. The air-to-air charge air cooler is upstream of the primary radiator with respect to flow of cooling air. The cooling system also includes an auxiliary engine fluid cooler which is located between the air-to-air charge air cooler and the primary radiator.

    摘要： A two stage cooled EGR system for a turbocharged internal combustion engine with an intake air charge air cooler. The first EGR cooler is a liquid-to-air cooler and the second, low temperature EGR cooler, is an air-to-air cooler combining with the gas flow downstream of the intake air cooler. The system bypasses EGR flow through the low temperature EGR cooler during certain engine conditions such as low engine coolant temperature and a check valve allows a limited portion of un-cooled, pressurized intake air to be passed through the low temperature EGR cooler for scavenging of any residual moisture and ultimate consumption by the engine.

    摘要： A work machine includes a primary power unit having a rated primary output. The primary power unit is couplable with at least one primary load, including a propulsion load. An auxiliary power unit is mechanically independent from the primary power unit, and has a rated auxiliary output which is smaller than the primary output. The auxiliary power unit is couplable with at least one external load, including an operator initiated load. At least one electrical processing circuit is configured for selectively coupling the primary power unit with one or more primary loads, and for selectively coupling the auxiliary power unit with one or more external loads.
