Abstract
The utility model relates to the oil injector of L 207 E series diesel for a locomotive. The utility model is the modification of the original equipment; a combustion-supporting iron is additionally arranged at the front of a spray head; the original independent spray head and a needle valve are sheathed to integration. The utility model effectively solves the problems that the oil dripping which is insufficiently burned because of non-atomization is diffused downwards along the wall of a cylinder jacket and surface of a lower plunger, and the lubricating oil is diluted, ineffective and waste. Simultaneously, the atomization quality of the fuel oil is also raised.
Description
The utility model relates to the oil sprayer of the L207E serial diesel engine that a kind of locomotive uses, and is the transformation to existing equipment.
Because the special construction of L207E serial diesel engine, require the oil sprayer level to install, oil sprayer for present employing, the fuel oil bundle is through the shower nozzle direct cylinder injection on the oil sprayer, so that the fuel oil bundle forms preceding and sprays the oil droplet that interruption can atomize afterwards, not fully burning and in action of gravity lower edge cylinder jacket wall and the diffusion downwards of lower piston surface causes lubricating oil dilution and lost efficacy and scrap.
The purpose of this utility model provides a kind of oil droplet that can prevent from fully not burn along cylinder jacket wall and lower piston surface diffusion, prolongs the lubricant oil oil sprayer in working life.
The purpose of this utility model is achieved in that
Before the shower nozzle of original oil sprayer, set up a combustion-supporting iron, before combustion-supporting iron, be provided with a seal ring, and former independently shower nozzle and needle-valve cover are combined into one, shorten needle-valve front end trapped fuel chamber.
The utlity model has following advantage:
1, owing to set up combustion-supporting iron, make the oil droplet that oozes out from shower nozzle and the oil droplet of not atomizing carry out the transition to the lower piston top, in order to avoid these micro-fuel oils are along cylinder liner and the diffusion downwards of lower piston surface, exempted oil dilution, prolong the working life of lubricant oil, helped solving the cylinder problem of embracing of L207E diesel engine, simultaneously, the fuel oil that can also be retained on the combustion-supporting iron can also burn, and has reduced oil consumption.
2, former independently shower nozzle and needle-valve cover are combined into one, have shortened needle-valve front end trapped fuel chamber, reduced the oil spout resistance, improved the fuel-oil atmozation quality.
Accompanying drawing is a structural representation of the present utility model.
Further narrate the utility model below in conjunction with accompanying drawing.
Combustion-supporting iron 1 of the present utility model is located at the front end of oil injector body 3, before combustion-supporting iron 1, be provided with seal ring 4, be provided with heat insulating washer 5 between combustion-supporting member 1 and the oil injector body 3, needle-valve cover 6 and shower nozzle 2 are an integral body, needle-valve 7 is positioned at needle-valve cover 6, the rear end of needle-valve 7 is provided with push rod 8 that promotes needle-valve 7 and the spring mechanism 9 that promotes push rod 8, and fuel oil enters in the oil injector body through filler opening 10.
Claims (2)
1, the oil sprayer used of a kind of L207E serial diesel engine, spring mechanism by needle-valve, needle-valve cover, shower nozzle, oil injector body, heat insulating washer, filler opening, push rod and promotion push rod is formed, the needle-valve cover is positioned at oil injector body, needle-valve is installed in the needle-valve cover, the front portion of oil injector body is provided with heat insulating washer, the spring mechanism of push rod and promotion push rod is positioned at the rear end of needle-valve, filler opening communicates with oil injector body, shower nozzle is positioned at the front portion of needle-valve cover, it is characterized in that: a combustion-supporting iron is installed before shower nozzle, before combustion-supporting iron, be provided with a seal ring, and needle-valve overlaps and shower nozzle is an one.
2, oil sprayer according to claim 1 is characterized in that: combustion-supporting iron adopts refractory steel to make, and the forward and backward seal ring of combustion-supporting iron adopts the composite heat resistance material.
