US Classification:

123469, 2988801

Abstract:

This disclosure provides a fuel line assembly for use with an internal combustion engine, an internal combustion engine including such as fuel line assembly, and a method for providing leak containment and detection in a fuel system, each of which include a double-walled fuel line including a high pressure fuel line component. The double-walled fuel line includes a high pressure fuel line, a jacket surrounding the high pressure fuel line, and a low pressure passage between the high pressure fuel line and the jacket. A fuel line nut includes a main body that houses a portion of the high pressure fuel line, and a first end portion supporting an enlarged end portion of the high pressure fuel line protruding from the first end portion. A second end portion of the fuel line nut sealingly connects to the jacket to extend the low pressure passage into an area between the main body and the housed high pressure fuel line. A fuel line connector mechanically and sealingly engages with the fuel line nut to house the supported enlarged end portion of the high pressure fuel line. The fuel line connector can connect to a single-walled high pressure tube provided in a bore of the cylinder head between an inlet of a fuel injector and the environment exterior of the cylinder head.

International Classification:

F02M 37/08

US Classification:

123497

Abstract:

A fuel supply system and method of controlling fuel flow through a supply system is provided including a variable flow, i.e. speed, electric fuel transfer pump and a control system adapted to variably control the transfer pump based on fuel demand of the engine. The system provides improved transient response by providing the transfer pump with a feed forward speed/flow command based on engine fueling demand determined based on engine operating conditions. The transfer pump is controlled based on fuel demand not necessarily achieved yet by the high pressure pump and injectors. Therefore, this system controls the EFTP substantially simultaneously with controlling the high pressure pump and injectors to optimize fuel flow through the entire system ensuring the minimum required fuel flow is passing through the second the fuel filtration system, hence maximizing steady state fuel filtration efficiency, and minimizing surge effects on filtration efficiency.

Assignee:

CUMMINS INTELLECTUAL PROPERTY, INC. - Minneapolis MN

International Classification:

F02F 1/10

US Classification:

123 4172

Abstract:

An improved cooling fluid passage configuration provides for uniformity of cooling about the entire periphery of a cylinder liner of an internal combustion engine in addition to improved cooling by increasing the flow in an upper water jacket of a split water jacket design. The cooling fluid passage configuration also provides a reduced pressure drop between a cylinder liner cooling fluid inlet and a cylinder head cooling fluid outlet when compared to conventional designs with a single head feed line, permitting use of a smaller cooling fluid pump and leading to increased efficiency of the engine.

B23P 6/00

US Classification:

1231932, 29888011

Abstract:

A cylinder liner sealing arrangement for an internal combustion engine including a cylinder block having cylinder bores, a cylinder head, a cylinder liner within each cylinder bore and a circumferential cut-out formed in the upper and outer surfaces of the cylinder liner. A circular sealing ring is positioned in the circumferential cut-out with the sealing ring contacting at least the cylinder block and the cylinder liner to form a coolant seal therebetween. The sealing ring includes a seal enhancing configuration formed on at least an outer circumferential surface of the sealing ring with the seal enhancing configuration including at least one of an arcuate portion of a “D” ring seal or a plurality of circumferentially extending ribs. Replacing the cylinder liner seal includes removing the cylinder head while maintaining the position of the cylinder liner within the respective cylinder bore, removing an upper liner seal from within the circumferential cut-out while maintaining the position of the cylinder liner within the cylinder bore, positioning a replacement sealing ring in the circumferential cut-out while maintaining the position of the cylinder liner within the cylinder bore and replacing the cylinder head on the cylinder block of the engine.
