摘要： A sealing interface configured to prevent galvanic corrosion of a container having parts made of dissimilar materials includes a first part, a second part, and a sealant. The first part has a first sealing surface and a first exterior surface substantially perpendicular to the first sealing surface. The second part has a second sealing surface and a second exterior surface substantially perpendicular to the second sealing surface. One of the parts includes an external sealing chamfer on the respective sealing surface extending to the respective exterior surface. The sealant at least fills a space formed between the external sealing chamfer and the sealing surface of the other of the parts when the parts are connected, forming a barrier between the parts such that the exterior surfaces of the parts are not in contact and are separated by the sealant. The exterior surfaces may be flush when the parts are connected.

摘要： A positive crankcase ventilation (PCV) system for an engine includes: a PCV tube defining a flowpath extending along an axis; a damage detection circuit associated with the PCV tube. The PCV system also includes a damage detection module that selectively indicates that a fault is present in the PCV tube based on a change in a characteristic of the damage detection circuit and that illuminates a malfunction indicator lamp (MIL) when the fault is present.

摘要： A Positive Crankcase Ventilation (PCV) channel disconnect detection device and method is provided for an engine having a crankcase, an intake system for delivering metered air to the engine, and a PCV channel for containing PCV gas flow between the crankcase and the intake system and having a first end and a second end. The PCV channel disconnect detection device includes a detection channel that supplies unmetered air surrounding one of the ends of the PCV channel to a post-throttle portion of the intake system. The detection channel is inoperable in response to a vacuum in the post-throttle portion of the intake system if the PCV channel connection is connected. The detection channel is operable in response to the vacuum in the post-throttle portion of the intake system if the PCV channel is disconnected. The detection channels may be configured to bypass all flow restrictions in the PCV system.

摘要： A crankcase ventilation system for an engine that may include a control valve and a disconnect fitting disposed in a conduit between the crankcase and an intake system. The disconnect fitting may include a tube wall, where the inside of the tube wall may have a support. The support may include at least one flow gap, and a plunger opening. The inside of the tube wall may have a plunger seat spaced apart from the support. A plunger may include a stem positioned in the plunger opening, that may be configured to translate in the opening. The plunger may include a head configured to engage the plunger seat to close flow. The conduit may include a segment configured for insertion into the disconnect to engage and unseat the plunger from the plunger seat to open flow.
