International Classification:

F02B 19/00

US Classification:

123266, 123273

Abstract:

An apparatus is disclosed including a first end defining an inner passage along a first inner surface of the first end, where the inner passage has threads structured to receive a spark plug. The apparatus further includes a second end opposite the first end and extending into a combustion chamber of a cylinder, the second end defining a pre-combustion chamber along a second inner surface and threads on an outer surface structured to thread into a spark plug hole in a cylinder head, which may be an enlarged spark plug hole. The second end includes holes that fluidly couple the pre-combustion chamber of the second end with the combustion chamber of the cylinder.

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.

International Classification:

F02M 31/04
F02B 29/04
F02D 41/00

Abstract:

An intake air circuit is structured to transmit intake air from a turbocharger compressor to an intake manifold of an engine. A charge air cooler (“CAC”), a bypass line, and a bypass heater are each positioned along the intake air circuit in parallel with each other. A first control valve is structured to controllably divert the intake air around the CAC. A second control valve is structured to controllably divert the intake air around at least one of the bypass line and the bypass heater. A controller operatively coupled to each of the engine, and the first and second control valves is structured to control each of the first and second control valves to cause the intake air to flow along a determined desired flow path based on each of measured ambient temperature and measured engine load.

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.
