摘要： An internal combustion engine and related components and methods of manufacturing and implementing an internal combustion engine and related components. The internal combustion engine includes a base, a cylinder block mounted onto the base, a cylinder head mounted onto the block, and a structural overhead member mounted onto the cylinder head, such that the cylinder head is positioned between the cylinder block and the structural overhead member. At least one through-bolt positioned in a through-bolt opening, the through-bolt opening extending from the base to the structural overhead member through the cylinder block and the cylinder head to couple the base, the cylinder block, the cylinder head and the structural overhead member together.

摘要： A nutating balance device for mitigating vibrations of an internal combustion engine having a crankshaft includes a coupler coupled to the engine crankshaft. The device also includes a weight coupled to the coupler. The coupler is configured to move the weight in sync with the crankshaft. The nutating balance device can generate variable torque pulsations or moments corresponding to torque harmonic frequencies of the internal combustion engine.

摘要： An engine system that includes a timing drive cavity defined by at least one of an engine block, front cover, and timing drive cover, a timing drive positioned within the timing drive cavity, and a fluid pump assembly. The fluid pump assembly includes an impeller housing, a fluid inlet port coupled to the impeller housing, and a fluid outlet port coupled to the impeller housing. At least one of the fluid inlet and fluid outlet ports is positioned at least partially within the timing drive cavity.

摘要： Engine lubrication systems and methods of manufacturing and implementing engine lubrication systems and methods. In particular embodiments, an engine system includes an internal combustion engine lubrication system that utilizes a stacked configuration of a through-bolted engine to pattern around through-bolts and utilizes substantially hollow bulkheads to define a central high-pressure lubrication reservoir that minimizes lube system pressure while maintaining pressure at the extremities of the lubrication circuit. Available space is utilized within the bulkheads to provide a lubrication drainage restriction for reducing lubrication losses at engine shut-down.
