Abstract: An engine system is disclosed. The engine system may have an engine having an accessory end and a drive end opposite the accessory end. The engine system may also have a turbocharger arrangement located adjacent the accessory end. The turbocharger arrangement may be configured to receive exhaust from the engine and to deliver compressed air to the air cooling arrangement. Further, the engine system may have an air cooling arrangement located adjacent the accessory end and configured to deliver fresh air to the engine. In addition, the engine system may have a mixing duct extending from the accessory end to the drive end and configured to receive the exhaust from the turbocharger arrangement. The engine system may also have an after-treatment system located adjacent the drive end. The after-treatment system may be configured to receive the exhaust from the mixing duct and to discharge the exhaust to an ambient.

Abstract: A heat exchanger is disclosed for use with an air handling system. The heat exchanger may have an inlet, an outlet, and at least one passage fluidly connecting the inlet and the outlet. The at least one passage may include a wall configured to transfer heat between a first fluid inside the at least one passage and a second fluid outside the at least one passage. The heat exchanger may also have a plurality of heat conducting features disposed along a length of the at least one passage, and a foul-resistant coating applied to only a subset of the plurality of heat conducting features.

Abstract: An engine system for a machine is disclosed. The engine system may have a first intake manifold configured to distribute air into a first cylinder bank of an engine. The engine system may also have a second intake manifold configured to distribute air into a second cylinder bank of the engine. The engine system may have a first exhaust manifold configured to discharge exhaust from the first cylinder bank to the atmosphere. The engine system may further have a second exhaust manifold configured to discharge exhaust from non-donor cylinders in the second cylinder bank to the atmosphere. In addition, the engine system may have a third exhaust manifold separate from the first and second exhaust manifolds and configured to recirculate exhaust from donor cylinders in the second cylinder bank to the first and second intake manifolds.

Abstract: An exhaust system is disclosed for use with an engine. The exhaust system may have a first exhaust manifold associated with a first plurality of engine cylinders, and a second exhaust manifold associated with a second plurality of engine cylinders. The exhaust system may also have a first exhaust gas recirculation passage extending from the first exhaust manifold to the first plurality of engine cylinders, and a second exhaust gas recirculation passage extending from the first exhaust manifold to the second plurality of engine cylinders. The exhaust system may additionally have a first cooler located in fluid communication with the first exhaust gas recirculation passage, and a second cooler located in fluid communication with the second exhaust gas recirculation passage.

Abstract: An axle sprung motor assembly for driving a locomotive includes a motor selectively driving a rotatable drive gear. A wheelset assembly includes a pair of flanged wheels mounted on an axle with an axle bearing housing rotatably supported on the axle. A set of resilient bushings is carried between the axle bearing housing and the motor housing. The motor assembly is resiliently secured to the wheelset through the interposed resilient bushings. A resilient gear has a hub fixed to the axle and includes a ring gear that engages the drive gear and is mounted to the hub through a set of flex bushings and a set of snubber bushings. Loads transferred from the motor to the wheelset are reduced by relative rotation between the ring gear and the hub that compresses elastomeric material of the flex bushings, with movement limited by the snubber bushings.
