摘要： A sealing structure includes an O-ring and a back-up ring. An outer diameter of the back-up ring is smaller than an inner diameter of a mounting portion of a delivery pipe. An inner diameter of the back-up ring is gradually increased from a pressure-receiving surface toward a seating surface, and is greater than an outer diameter of a fuel introducing portion of a fuel injection valve. In a section of the back-up ring, an edge angle defined between the pressure-receiving surface and an inner circumferential surface is smaller than a gap angle defined between the pressure-receiving surface and a tapered outer surface of a tapered portion in the fuel introducing portion. A dimension of the seating surface in the back-up ring is shorter than a dimension in an end surface.

摘要： A decoupling element for a fuel-injection device has a low-noise and pivotable construction. The fuel-injection device includes at least a fuel injector and a receiving bore in a cylinder head for the fuel injector as well as the decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element is in the form of a ring, in particular a closed ring, which has a lower end face that sits on a shoulder of the receiving bore, and which has an upper end face that rises conically from radially outside toward radially inside and is in intimate contact with a spherically curved shoulder area of the valve housing of the fuel injector. The fuel-injection device is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing combustion engine having externally supplied ignition.

摘要： Disclosed is a surge chamber configured for releasably connecting a fuel injector to a fuel injection testing machine in an adjustable manner to accommodate the various fuel injector orientations produced by different manufacturers. The apparatus generally comprises a surge chamber, a quick connect assembly, and a coupler adapted to connect to the fuel injector being tested. The quick connect attaches to the surge chamber, and the coupler is configured to securely and removably connect the fuel injector to the quick connect via the fuel injector inlet. The test fluid passes from the surge chamber, through the quick connect and coupler, and into the injector, where it is typically injected into a spray chamber. In another embodiment, the chamber comprises a swivel cap that permits rotation of the chamber about its longitudinal axis. Such rotation may be desirable where the fuel injection inlet does not connect to the fuel injector at a 90-degree angle, or where the configuration of the fuel injection testing machine requires the injector to be oriented at a certain angle to properly engage the spray chamber.

摘要： A decoupling element for a fuel injection device provides a low-noise construction. The fuel injection device has at least one fuel injection valve and a receiving bore in a cylinder head for the fuel injection valve as well as the decoupling element between a valve housing of the fuel injection valve and a wall of the receiving bore. The spring rigidity of the decoupling element is so low and the decoupling element is placed between the valve housing of the fuel injection valve and the wall of the receiving bore in such a way that the decoupling resonance is located in the frequency range below 2.5 kHz. The fuel injection device is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignited internal combustion engine.

摘要： The present disclosure provides an enclosure or containment assembly adapted to seal a high pressure fuel rail, and an engine system including such an enclosure or containment assembly. The assembly includes two portions that can sealingly engage to form an enclosure or compartment that contains the high pressure fuel rail. Fuel line connectors leading into the enclosure to ports of the high pressure fuel rail are in a sealing engagement with the enclosure to seal the high pressure fuel rail from the atmosphere and provide an enclosed low pressure region between the high pressure fuel rail and an inner surface of the enclosure. In this way, leaked fuel can be collected from the high pressure fuel lines and contained. The collected and contained leaked fuel can be channeled to a leak detector, which can trigger an alarm with detection of a leak.

摘要： 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.
