The compressor is configured to produce the charge air. A second turbo machine is configured to receive a portion of the exhaust and rotationally drive a pump in response thereto. High temperature and low temperature EGR heat exchangers are arranged in the exhaust gas recirculation passage serially relative to one another upstream from the pump. A heat exchanger arranged in the exhaust gas recirculation passage upstream from the pump. A water separator is arranged in the exhaust gas recirculation passage fluidly between the heat exchanger and the pump. An EGR catalyst is arranged in the exhaust gas recirculation passage upstream from the heat exchanger.

International Classification:

F02F 1/18
F02F 1/22
F02B 75/28
F02F 1/00

Abstract:

An opposed-piston engine assembly is disclosed including a first cylinder liner containing a pair of first pistons that move toward one another in one mode of operation and away from one another in another mode of operation. The pistons are coupled to first and second crankshafts. Multiple block segments arranged in a side-by-side abutting relationship form the engine block including a first outboard segment, a first inboard segment, a second inboard segment, and a second outboard segment. Tensile members extend through the block segments tying them together as one structural unit. The first and second inboard segments abut one another at a seam and include bores that cooperate to receive the first cylinder liner. The first cylinder liner includes a liner support collar that is received in counter-bores defined by the first and second inboard segments at the seam between the first and second inboard segments.

Inventors:

- Plymouth MI, US
Gary L. HUNTER - Brighton MI, US
Julian SHERBORNE - Novi MI, US

International Classification:

F02M 26/04

Abstract:

A powertrain system is provided and may include a combustion engine, a crankshaft, and a turbo-compounding system. The combustion engine may include an intake manifold and an exhaust manifold. The crankshaft may be driven by the engine. The turbo-compounding system may be configured to drive the crankshaft and may include a first turbine and a drive system. The first turbine may include an inlet fluidly communicating with the exhaust manifold. The drive system may include an input shaft driven by the first turbine, and an output shaft engaged with the crankshaft. The drive system may be configured to drive the output shaft at more than one drive ratio relative to the input shaft.

Inventors:

- Plymouth MI, US
Gary L. HUNTER - Brighton MI, US

International Classification:

F02M 61/14
F01B 7/02
F02B 25/08

Abstract:

An opposed piston engine may include a first housing, first and second pistons, and first, second, and third fuel injector nozzles. The first housing may define a first passage extending along a first longitudinal axis. The first and second pistons may be slidably disposed within the first passage. The first, second, and third fuel injector nozzles may be in fluid communication with the first passage. At least one of the first, second, and third fuel injector nozzles may be angularly offset from another one of the first, second, and third fuel injector nozzles by an oblique angle about the first longitudinal axis.

Appl. No.:

15/050883

Inventors:

- Plymouth MI, US
Gary L. HUNTER - Brighton MI, US

International Classification:

F02M 61/14
F02M 51/06
F02B 75/28

Abstract:

A fuel injector includes a nozzle, a needle, and a pressure control section. The nozzle has first and second ends and extends along a first longitudinal axis from the first end to the second end. The nozzle includes a nozzle body defining a first longitudinal passage that extends along the first longitudinal axis and through the second end of the nozzle. The needle is disposed within the first longitudinal passage and is movable between a first position in which the needle prevents fuel from flowing through the second end of the nozzle and a second position in which the needle allows fuel to flow through the second end. The pressure control section extends along a second longitudinal axis that is angularly offset relative to the first longitudinal axis of the nozzle. The pressure control section includes an electromechanical actuator that actuates the needle between the first and second positions.
