摘要： A first plate portion abuts against a cylinder head and has a substantially constant plate thickness. A second plate portion abuts against a cylinder block and has a substantially constant plate thickness. An intermediate plate portion is sandwiched between the first plate portion and the second plate portion and has a substantially constant plate thickness. A shim is sandwiched between the first plate portion and the intermediate plate portion and is disposed over an entire periphery of a peripheral edge of a combustion chamber hole. The shim includes a gradually changing portion. The gradually changing portion has a thickness in the hole axis direction that becomes thicker with a separation from the peripheral edge of the combustion chamber hole.

摘要： A vehicle drive device includes an internal combustion engine, a power transmission device, and a reinforcing member coupled to both the internal combustion engine and the power transmission device. A seal is arranged between a cylinder head and a cam housing that are adjacent to each other in a direction parallel to an axis of a cylinder. A reinforcing member is coupled to the cam housing. A first fastening portion of the cam housing that is fastened to the reinforcing member is arranged at a position away from a contact portion of the cam housing that contacts the seal in the direction parallel to the axis.

摘要： An apparatus is provided to test valves. The apparatus includes an actuation mechanism having an actuator that seals a valve of a combustion chamber of an engine. The apparatus further includes a flow control device that controls a flow of a pressurized fluid to the combustion chamber. The apparatus further includes a plurality of sensors having a first sensor and a second sensor. The first sensor is disposed in an inlet port of the combustion chamber to detect a first flow rate of the pressurized fluid in the inlet port. The second sensor is disposed in an exhaust port of the combustion chamber to detect a second flow rate of the pressurized fluid in the exhaust port. The apparatus further includes a notification device configured to generate an alert based on the detected first flow rate and the detected second flow rate.

摘要： A sealing assembly for establishing a gas and fluid tight seal in an internal combustion engine is provided. The sealing assembly includes a plate of metal which has a plurality of openings and at least one generally flat surface. The plate also has at least one shelf which circumferentially surrounds one of the openings and which opens to the generally flat surface and the opening. The sealing assembly further includes at least one sealing bead of an elastically compressible material which is engaged with the shelf and extends outwardly therefrom past the generally flat surface for sealing the plate with another component in the internal combustion engine.

摘要： A cam cover cap plug for use with a cylinder head assembly to fill the opening that remains when an accessory unit such as a READ utility pump is not utilized. The cam cover cap plug is preferably a one-piece, molded component formed from a plastic or a metal. The cam cover cap plug includes a back, a front, an upper surface and a lower surface. The upper surface is arched and defines a half-round configuration. The lower surface is flat and includes integrated cylinder head fasteners extending from the flat surface. The arched, half-round configuration of the upper surface provides a full and complete sealing area with the half-round opening of the cam cover formed to receive the accessory unit. The fasteners of the lower surface are preferably integrated dowels. The integrated dowels locate the cam cover cap plug base to the cylinder head of the cylinder head assembly.
