International Classification:

F02M 27/02

US Classification:

60278

Abstract:

An internal combustion engine system includes a spark-ignited internal combustion engine powered by a gaseous fuel. The engine system also includes an air intake in air providing communication with the internal combustion engine. Further, the engine system includes an exhaust system in exhaust gas receiving communication with the internal combustion engine. The exhaust system includes a methane oxidation catalyst through which at least a portion of the exhaust gas flows and an exhaust gas recirculation line in exhaust gas providing communication with the air intake.

Abstract:

A system and method for condensation management in a low-pressure loop EGR system are provided. The system includes an EGR condensation temperature module configured to determine an EGR condensation temperature of recirculated exhaust gas upstream of an EGR cooler and an EGR coolant temperature controller communicably coupled to the EGR condensation temperature module. The EGR coolant temperature controller provides EGR coolant to the EGR cooler at or above the EGR condensation temperature. The system also includes a charge air condensation temperature module configured to determine a charge air condensation temperature of charge air upstream of a charge air cooler and a charge air coolant temperature controller communicably coupled to the charge air condensation temperature module. The charge air coolant temperature controller provides charge air coolant to the charge air cooler at or above the charge air condensation temperature.

International Classification:

F01N 3/10

US Classification:

60274, 60299

Abstract:

A system and method for reforming a portion of an exhaust gas stream in an internal combustion engine system. An exhaust gas recirculation assembly divides the exhaust gas stream into a recycle stream and a vent stream. A mixer in fluid receiving communication with the recycle stream forms a combination stream by mixing a gaseous fuel stream with the recycle stream. A thermochemical recuperator component fluidly connects to the mixer and includes a first flow path and a second flow path. The first flow path has a catalyst through which the combination stream flows to create a reformate stream, and the second flow path has a heat transfer area for transferring heat from the vent stream to the combination stream.

International Classification:

F02D 41/30

US Classification:

123704

Abstract:

An apparatus for dithering fuel into an internal combustion engine includes a turbine that is powered by the internal combustion engine and a first fuel injector that injects a first fuel into an air stream to create a fuel/air stream. The apparatus also includes an air/fuel compressor that provides a compressed fuel/air stream to the internal combustion engine. The air/fuel compressor is powered by the turbine, and the air/fuel compressor compresses the fuel/air stream to create the compressed fuel/air stream. Additionally, the apparatus includes a second fuel injector that injects a second fuel into the compressed fuel/air stream prior to the compressed fuel/air stream entering the engine and after the compressed fuel/air stream exits the air/fuel compressor.
