Abstract: A cylinder head for an internal combustion engine includes a casting and plug. The casting defines a first channel, a second channel, and a bore extending inward from an exterior surface of the casting. The first channel intersects a central portion of the bore. The second channel intersects an opposing end of the bore relative to the exterior surface. The plug is disposed within the bore. The plug has a distal end that engages the casting along the opposing end of the bore via a slip-fit engagement, a proximal end that engages the casting within the bore proximal to the exterior surface via a fixed engagement, and an intermediate portion that is spaced apart from the casting along the central portion of the bore. The plug defines an internal channel that establishes fluid communication between the first and second channels.

Abstract: An anti-rotation oil filter system to prevent inadvertent release of the oil filter from a lubrication system is provided. The system includes a ratchet gear attached to one of either the oil filter or the engine's oil filter attachment base. In both embodiments, a spring-loaded ratchet release pawl is provided to engage the ratchet and to thereby hold the filter in place against the attachment base until such time as the filter needs to be changed. Where the ratchet gear is fitted to the filter, a ratchet release pawl is associated with the engine's oil filter attachment base. The teeth of the ratchet ring gear extend outwardly from the filter. Alternatively, where the ratchet gear is fitted to the engine's filter attachment base, a ratchet release pawl is associated with the filter. Regardless of the embodiment, the ratchet gear and pawl arrangement restricts filter rotation to maintain clamp load.

Abstract: In certain situations, it is desirable to mount an engine accessory to a frame member of the vehicle. Such frame member might be a convenient structural element proximate a desired location for the engine accessory. Because the frame member is often hollow, conventional mounting techniques may crush it. A system and method for attaching first and second brackets to the frame member are disclosed. The bracket systems may have piloting, locating, and anti-rotation features to provide secure attachment points. A vehicle accessory is mounted at the distal ends of the first and second brackets.

Abstract: Methods and systems are provided for improved component temperature protection during individual cylinder knock control. Cylinder spark adjustments may be performed individually based on respective cylinder adaptive knock estimates. Bank to bank engine fueling may then be performed to control the exhaust temperature of each engine bank, independently.
