An engine oil receiving structure comprises a vertically disposed crank shaft, a laterally movable piston, a connecting rod connecting the crank shaft and the piston, a cylinder barrel housing the crank shaft and the piston, a crank case containing the crank shaft together with the cylinder barrel, a cylinder head forming a combustion chamber, the combustion chamber connecting to a piston movable part end face of the cylinder barrel, an oil filter filtering engine lubricant, and an oil case storing oil flowing out when the oil filter is removed from a mounted position, and the oil case is fixed to an engine under the oil filter, and comprises a discharge path to discharge the stored oil.

This disclosure generally relates to an oil mitigation system and method for lubricating the piston(s) for electronic fuel injected internal combustion engines, incorporating cylinder deactivation technology. This concept leverages the engine's base fuel injection pulse width table, determines the fuel injection “shutoff” state and, reduces the oiling to counter the reverse oil flow effect within the cylinder wall, past the ring set to the cylinder combustion chamber. This disclosure further comprises a system and method for mitigating oil consumption to all active cylinders, for accommodating all ranges of engine loading.

Engine includes: crankcase housing crankshaft extending in vertical direction; cylinder block mounted on side of crankcase and formed with cylinder; cylinder head mounted on side of cylinder block and provided with air inlet port and air outlet port communicating with cylinder; cylinder head cover mounted on side of cylinder head and covering air inlet port and air outlet port; mount case including: supporting portion provided below crankcase and cylinder block and supporting crankcase and cylinder block; and extending portion extending from supporting portion below cylinder head and cylinder head cover; oil pan provided below mount case and storing lubricating oil; and communication tube communicating first space formed between cylinder head and cylinder head cover and second space formed between mount case and oil pan. Communication tube is provided between cylinder head cover and extending portion.

A system comprises a component manufactured via additive manufacturing. The component includes a first material with a first contraction rate. An insert is disposed in the component and comprises a second material with a second contraction rate that is lower than the first contraction rate. When the component and the insert are exposed to a temperature suitable for sintering, the component contracts around the insert, thereby coupling the insert and the component.

An internal combustion engine includes an engine lubrication fluid storage system with a primary storage volume and a secondary storage volume that is separate from the primary storage volume. The secondary storage volume is linked to the primary storage volume with a fluid flow path that is throttled so that lubrication fluid is stored in the secondary storage volume during engine operation, and drains from the secondary storage volume to the primary storage volume when the engine is not running.

An engine mounting assembly includes a front frame element defining, in part, a structural load bearing assembly, a differential case mounted to the frame at a frame mounting area, and an oil pan having upright and bottom walls defining an oil sump. The differential case has an opening configured to receive an axle assembly and has walls defining a pan-receiving recess. The oil pan is configured to conform to the pan-receiving recess to be supported by the differential case and overlap the frame mounting area. The oil pan has a mounting flange extending from the upright walls and mounting bores that receives mounting bolts for coupling the oil pan to the engine and the oil pan to the differential case. The differential case and the oil pan form part of the structural load bearing assembly of the work vehicle to transfer structural loads to and from the front frame element.
