Abstract

DC60 (24/06/56) Improvements to the lubrication system for small internal combustion engines. The lubrication system for internal combustion engine 1, which incorporates oil pump 42 driven by the crankshaft rotation 9 after reducing the crankshaft rotation speed, is characterized by the reduction gear ratio being set in such a way that the rotational speed range of oil pump 42 is equal to or less than two-thirds of the critical rotational speed at which cavitation occurs in oil pump 42, and the discharge capacity of oil pump 42 is set to correspond to the pre-estimated amount of engine oil required by internal combustion engine 1 within the rotational speed range. Improvements to the lubrication system for small internal combustion engines. The lubrication system for internal combustion engine 1, which incorporates oil pump 42 driven by the crankshaft rotation 9 after reducing the crankshaft rotation speed, is characterized by the reduction gear ratio being set in such a way that the rotational speed range of oil pump 42... The oil pump capacity of the 42 will be equal to or less than two-thirds of the critical rotational speed at which cavitation will occur in the 42 oil pump, and the discharge capacity of the 42 oil pump is set to correspond to the pre-estimated amount of engine oil required by the internal combustion engine 1 within the range of rotational speeds.

Claims (1)

Disclaimers (all) that will not appear on the advertisement page: 1.Lubrication system for internal combustion engines Including the gas station which is driven by rotation Of the crankshaft after the crankshaft speed has been reduced With specific characteristics The internal combustion engine has a significantly horizontally positioned cylinder axis, a contact hole leading through the crankcase is provided in the vent of the said gas pump. Assembly piece for the formation of an oil spray stream. Aligned towards the cylinder holes where the axial line is significantly horizontal, through a significantly linear oil path from such contact holes will be installed. Is in The surface of the inner wall of the crankcase In such a way that oil will be supplied to the assembly For the formation of such a stream of oil spray The oil pump is driven by an intermediate gear which is provided between the drive gear. Of the said crankshaft And the gear according to the said oil pump after the speed of the shaft The crank was lowered and the intermediate gear was placed under the crankshaft. And the gear according to the pump The engine oil is positioned at a height that is significantly equal to the height of the gears between. It is closer to the cylinder side than the intermediate gear.
