20090139483MATERIALS AND PROCESSES FOR REDUCING COMBUSTION BY-PRODUCTS IN A LUBRICATION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - A lubrication system having an oil filter modified to replace or supplement the performance of lubricant additives that may be used within an internal combustion engine to increase the performance of a lubricant. The formulation of the lubricant is changed in accordance with the chemicals placed in the oil filter. For example, when the oil filter contains a strong base, the lubricant concentration of detergent will decrease, in some cases to zero, while the dispersant concentration in the lubricant will increase. The dispersant is the ideal weak base to neutralize combustion acid at the piston ring zone, carry the resultant weak base-combustion acid complex to the strong base in the oil filter, undergo ion exchange with the strong base, immobilize the acid in the oil filter and recycle back to the piston ring zone for reuse as an acid neutralization agent. The reduction or elimination of detergent from the lubricant will reduce the fouling of the emission filter and of deposit formation on engine parts such as the piston. The oil filter may also contain an additive which is slowly released into the lubricant. For example, a ZnDDP anti-wear additive may be slowly released from the oil filter to the lubricant. Because the ZnDDP has low molecular weight alkyl groups it has limited solubility in the lubricant. The rate of release is limited by the equilibrium concentration of the additive in the lubricant. As a result, a relatively constant concentration of the additive may be maintained in the lubricant. The resultant closed system allows the oil drain intervals to be significantly extended.06-04-2009

20090139483MATERIALS AND PROCESSES FOR REDUCING COMBUSTION BY-PRODUCTS IN A LUBRICATION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE - A lubrication system having an oil filter modified to replace or supplement the performance of lubricant additives that may be used within an internal combustion engine to increase the performance of a lubricant. The formulation of the lubricant is changed in accordance with the chemicals placed in the oil filter. For example, when the oil filter contains a strong base, the lubricant concentration of detergent will decrease, in some cases to zero, while the dispersant concentration in the lubricant will increase. The dispersant is the ideal weak base to neutralize combustion acid at the piston ring zone, carry the resultant weak base-combustion acid complex to the strong base in the oil filter, undergo ion exchange with the strong base, immobilize the acid in the oil filter and recycle back to the piston ring zone for reuse as an acid neutralization agent. The reduction or elimination of detergent from the lubricant will reduce the fouling of the emission filter and of deposit formation on engine parts such as the piston. The oil filter may also contain an additive which is slowly released into the lubricant. For example, a ZnDDP anti-wear additive may be slowly released from the oil filter to the lubricant. Because the ZnDDP has low molecular weight alkyl groups it has limited solubility in the lubricant. The rate of release is limited by the equilibrium concentration of the additive in the lubricant. As a result, a relatively constant concentration of the additive may be maintained in the lubricant. The resultant closed system allows the oil drain intervals to be significantly extended.06-04-2009

20120031367CYLINDER BORE WALL OIL SQUIRTER, RECIPROCATING ENGINE EMBODYING SAME AND WHERE THE ENGINE FURTHER EMBODIES A ROLLERIZED CRANKTRAIN - Featured is a cylinder wall oil delivery system for a reciprocating engine having at least one cylinder and at least one piston movably received in the cylinder as well as a reciprocating engine embodying such a cylinder wall oil delivery system. Such an oil delivery system includes a squirter that is fixably arranged in each cylinder so that oil is directed therefrom to two different areas of the cylinder wall. The squirter includes a first nozzle being orientated so the oil is directed to one of the two cylinder wall areas and a second nozzle being orientated so the oil is directed to the other of two cylinder wall areas. In particular embodiments, the squirter is arranged so the oil targets the piston skirt thrust and anti-thrust travel areas of the cylinder wall and so as to regulate the oil flow from each nozzle.02-09-2012
20080264377FUEL INJECTION LUBRICATION MECHANISM FOR CONTINUOUS SELF LUBRICATION OF A FUEL INJECTOR - Disclosed is an apparatus and method for lubricating a plunger residing within a bushing of a fuel injector. The apparatus includes a fuel lubrication mechanism comprised of lubrication grooves formed within and around the outer axial surfaces of the plunger. The grooves act as fuel reservoirs for storing a small portion of fuel on the outer axial surface of the plunger. The stored or retained fuel interfaces with the walls of the bushing during injection to provide a lubricated interface between the bushing and plunger. The lubricated interface increases the service life of the fuel injector by reducing seizing, scoring and scuffing caused by excessive heat.10-30-2008

20100313843LUBRICATION DEVICE FOR GAS ENGINE - Providing a gas engine in which the drain oil in the blow-by gas as a lubricant is mixed into the air fuel-gas mixture, the lubricant actively lubricating the bearing surfaces of the wear parts such as the valve seats and valve guides as to the intake-air valve and the exhaust gas valve, so that the lubricating device improves the engine lubricating conditions. A lubrication device for a gas engine thereby a valve gear room 12-16-2010
20120210972VERTICAL ENGINE - A vertical engine includes: an oil pump provided adjacent to the lower surface of a cylinder barrel and connected to a lower end portion of a cam gear shaft to be driven by the gear shaft; a first lubricating oil passageway for supplying lubricating oil from the oil pump to a lower bearing of a crankshaft; a second lubricating oil passageway extending through the crankshaft from the lower bearing to an upper bearing of the crankshaft; a third lubricating oil passageway provided adjacent to the upper surface of the barrel and extending from the crankcase to immediately below stem end portions of intake and exhaust valves so that lubricating oil leaked from the second lubricating oil passageway flows therethrough; and a fourth lubricating oil passageway for returning lubricating oil, dripped down from the third lubricating oil passageway to the stem end portions, to the pump.08-23-2012
