Embodiment Construction
[0013] A specific embodiment of the present invention is shown in Fig. 2, and internal combustion engine cylinder lubricating oil filling device comprises high pressure oil source oil inlet valve 1, cylinder oil distributor 2, oil outlet valve 3, oil injection control valve 4, hydraulic block 1 5, pressure relief control Valve 8, hydraulic block 2 9, low pressure drain valve 10, common rail accumulator 11, oil measuring piston 12, oil measuring piston body 13. The oil measuring piston 12 and the oil measuring piston body 13 are a pair of parts, which form the oil measuring chamber 6 and the common rail chamber 7 after matching; the oil injection control valve 4 is a two-position three-way solenoid valve or other forms with the same function Solenoid valve, pressure relief control valve 8 is also a two-position three-way solenoid valve or other forms of solenoid valves with the same function. The functions of oil injection electric control valve 4 and pressure relief control val...

The invention discloses a cylinder lubricating and oiling device for an internal combustion engine. The device comprises a mating plate of an oil measuring piston and an oil measuring piston body. The mating plate forms an oil measuring cavity and a common rail cavity after mating. Two hydraulic blocks are arranged at two ends of the oil measuring piston body so as to limit the maximum stroke of the oil measuring piston. An oiling control valve and a decompression control valve are simultaneously actuated and released so as to control the communication between the common rail cavity and a high pressure oil source and the blockage of an oil path between the common rail cavity and a low pressure oil relief valve and the blockage between the oil measuring cavity and the high pressure oil source, and the communication of the oil path between the oil measuring cavity and a cylinder oil distributor, or the blockage between the common rail cavity and the high pressure oil source and the communication between the common rail cavity and a low pressure oil return pipe, and the communication between the oil measuring cavity and the high pressure oil source and the blockage of the oil path between the oil measuring cavity and the cylinder oil distributor. The cylinder lubricating and oiling device for the internal combustion engine has a simple structure and realizes the approximate constant high pressure oiling.
Description
technical field [0001] The invention relates to a lubricating and oiling technology for an internal combustion engine cylinder, in particular to a lubricating and oiling device for an internal combustion engine cylinder. Background technique [0002] Internal combustion engines typically have one or more cylinders that include a cylinder liner and a piston that typically has three to five pressure-tight piston rings that slide on the inner surface of the cylinder liner. The purpose of cylinder lubrication is to maintain the cylinder liner Lubricating oil film on the inner surface in order to keep the friction between the inner surface of the cylinder liner and the piston rings at a suitably low level. Each cylinder liner has several lubrication points where oil is supplied by one or more cylinder lubricating devices. [0003] Chinese Invention Patent Publication CN1183509A discloses a cylinder lubricating device for a multi-cylinder internal combustion engine, which is appl...
