An exemplary multi-position mount system for a powertrain component includes a mount assembly including a mount housing having a first mount edge defining a rectangular mount opening with at least two mount notch openings on each side of the rectangular mount opening, a sleeve insert having at least two insert tabs extending from each side of the insert, the insert having an insert opening with at least two insert notch openings on each side of the insert opening, a damping assembly including an alignment tab extending from each side of the damper body, and a T-bracket including a T-bracket sleeve having an edge defining an offset opening in the T-bracket sleeve. The sleeve insert interfaces with the mount housing and is rotatable within the mount opening, the damping assembly is rotatable within the insert opening, and the insert opening is spaced apart from the mount opening.

A flow guiding appliance of a turbomachine, in particular of an aircraft engine, for a partial exit flow of an outlet guide vane of a compressor, wherein, a flow guiding element delimits an annular channel about a shaft of the turbomachine. A frictional engagement connecting surface at the circumference of the flow guiding element connects the flow guiding element to another structural component of the turbomachine. The frictional engagement connecting surface with a closed enveloping surface can be inserted in a deformed state into the structural component with a circular cylindrical sealing surface with at least two opposite points. The at least two points of the closed enveloping surface are arranged in at least two opposite frictionally engaged contact areas of the circular cylindrical sealing surface following deformation. The invention also relates to a method for creating a flow guiding element.

This application discloses a cylinder block structure including: a cylinder block surrounding a cylinder array formed by a plurality of cylinders lined up in a first direction; a reinforcement plate including: a first fastening portion fastened to the cylinder block; and a second fastening portion fastened to the cylinder block at a position separated from the first fastening portion in a second direction that intersects with the first direction; and an oil pump that supplies oil to the cylinder block. The oil pump is fastened to the cylinder block together with the reinforcement plate. The reinforcement plate is interposed between the cylinder block and the oil pump, and has a length that is equal to or more than half of the cylinder array in the first direction.

A cylinder block assembly has: a cylinder block having three cylinders aligned side-by-side; and four crank caps arranged side-by-side in an alignment direction of the cylinders and fastened to the cylinder block. The crank caps and the cylinder block are provided with crank bearings which rotatably support a crankshaft. The crank caps are arranged at both sides of each cylinder in the alignment direction. Intermediate crank caps positioned at intermediate positions in the plurality of the crank caps include removed parts so as to more easily deform when receiving a load from the crankshaft compared with the side crank caps.

An engine assembly having an improved mounting system or assembly is disclosed. Features of this mounting system include having crankcase arms that are integrally formed with a crankcase of the engine assembly, having multiple mounting legs that each have a dedicated vibration damping subassembly and where the stiffness of at least two of the mounting legs is different (by varying the configurations of the corresponding vibration damping subassemblies), and using a mounting ring or base with having differently oriented mounting pads for securement of the corresponding mounting leg relative thereto.

Provided is an engine device that can enlarge a space inside a case without lowering support stiffness. An engine (2) is attached to a case (11) via support parts (81, 82). A rear lower portion support part (82), which is one of the support parts, includes an attachment rib (11b) as a mounting part provided in the case (11) and an attachment bracket (91) fastened to a bottom of a crankcase (46) by a fastening bolt (90) and attached to the attachment rib (11b). The fastening bolt (90) penetrates through a through hole (92a) provided in the attachment bracket (91) and is screwed into a screw hole (46e) formed obliquely inward at a corner of the bottom of the crankcase (46).

An exemplary multi-position mount system for a powertrain component includes a mount assembly including a mount housing having a first mount edge defining a rectangular mount opening with at least two mount notch openings on each side of the rectangular mount opening, a sleeve insert having at least two insert tabs extending from each side of the insert, the insert having an insert opening with at least two insert notch openings on each side of the insert opening, a damping assembly including an alignment tab extending from each side of the damper body, and a T-bracket including a T-bracket sleeve having an edge defining an offset opening in the T-bracket sleeve. The sleeve insert interfaces with the mount housing and is rotatable within the mount opening, the damping assembly is rotatable within the insert opening, and the insert opening is spaced apart from the mount opening.

In an internal combustion engine, an oil separator provided in a blowby gas passage is attached to a side wall of a cylinder block. A first communicating passage and a second communicating passage via which the inside of a crankcase is connected to the oil separator are formed in the cylinder block. An opening of the first communicating passage on the crankcase side and an opening of the second communicating passage on the crankcase side are placed to be distanced from the center of the crankcase in the extending direction of a crankshaft so as to sandwich the center of the crankcase. No passage via which the inside of the crankcase is connected to the oil separator is provided between the first communicating passage and the second communicating passage.

Methods and systems are provided for an engine component assembly having one or more fastener retention apparatuses. In one example, a system may include each of the one or more fastener retention apparatuses including a rigid limiter and an integrated fastener retention feature adhered to an inner surface of an interior passage of the rigid limiter. Further, one or more fasteners may be held captive by each of the one or more fastener retention apparatuses capturing one fastener of the one or more fasteners.

This application discloses a cylinder block structure including: a cylinder block surrounding a cylinder array formed by a plurality of cylinders lined up in a first direction; a reinforcement plate including: a first fastening portion fastened to the cylinder block; and a second fastening portion fastened to the cylinder block at a position separated from the first fastening portion in a second direction that intersects with the first direction; and an oil pump that supplies oil to the cylinder block. The oil pump is fastened to the cylinder block together with the reinforcement plate. The reinforcement plate is interposed between the cylinder block and the oil pump, and has a length that is equal to or more than half of the cylinder array in the first direction.
