Abstract

The invention relates to an oil ring doctor blade opening positioning device. The device is a positioning notch; the positioning notch is formed at the internal circle of one side of an oil ring doctor blade opening; and the device is arranged at a stop hole of a piston. The device has the advantages that: 1, the doctor blade opening has a positioning function, and the problems of blue smoke and high engine oil consumption which are generated in starting of a horizontal engine or an engine with a relatively small inclination angle are solved; 2, the device is convenient to install, and only the positioning notch is installed at the stop hole of the piston; and 3, the device has a simple processing technology and is low in cost.

Description

technical field [0001] The invention relates to an oil ring circumferential positioning device for preventing lubricating oil in a crankcase from flowing back along a piston ring opening, in particular to an oil ring scraper opening positioning device. Background technique [0002] The main function of the oil ring is to adjust the lubricating oil, scrape off the excess lubricating oil on the cylinder wall during work, and at the same time ensure that the friction is accompanied by sufficient oil film lubrication. Due to the irregular rotation of the piston ring in the circumferential direction when the engine is working, it is possible that when the engine is stopped, the openings of the upper and lower scrapers of the oil ring are vertically below. , the lubricating oil in the crankcase will enter between the oil ring and the steam ring through the opening of the scraper ring, and may also enter the combustion chamber. This part of the lubricating oil cannot be scraped bac...
