Description
Technical field:
The utility model relates to the technical field of positioning device on diesel engine, more specifically to the positioning device that oil sprayer on a kind of diesel engine is installed.
Background technique:
Two traditional at present valve diesel, by the restriction that inlet and outlet door is arranged, oil sprayer departs from cylinder centerline usually, to tilt certain angle with cylinder-bore axis, eccentric design also must be done in the firing chamber that result in piston head, and the cooling of this formation for mixed gas, the tissue of combustion process, the heat load of piston and cylinder cap ridge area is all very unfavorable.Oil sprayer tilting, each spray orifice of oil sprayer also can be caused to spray oil mass uneven, incomplete combustion, it is poor to discharge.
Four-valve diesel engine oil sprayer central vertical is arranged, makes each spray orifice fuel flow direction substantially identical, and the oil mass of each spray orifice ejection is even, and oily Shu Changdu is equal, and firing chamber realizes center arrangement.Under given intake duct swirl rate, bowl in piston center arrangement can produce maximum eddy current in combustion recess, and form symmetrical crowded stream, oil gas is fully mixed, reach Thorough combustion, thus reduction noxious emission generates and improves the Economy of diesel engine, improves the power character of diesel engine.In addition, oil sprayer is arranged vertically and the oily stream of oil nozzle can be made to trend towards equalization, and every root oil Shu Douneng is close to the air of equivalent, and therefore, the temperature between every root oil bundle main combustion period also can keep identical and close to optimum value.
From development angle, four-valve diesel engine replaces two traditional valve diesel has become necessary development trend, and employing Four-valve technology is the development of Design Technology for Diesels thought, is also the result that user improves day by day to diesel engine performance requirement.
But adopt Four valve structure, the postpone of oil sprayer central vertical cloth, oil sprayer has to all hide in inlet casing housing, and the oil-feed arm of oil sprayer, through the hole of valve mechanism cover side, is connected with high-pressure oil pipe.If four oil sprayer angles are installed not in place, after waiting oil sprayer fixing, valve mechanism cover cannot be installed; Or four oil sprayer setting angles slightly deviation, after valve mechanism cover installs, diesel engine is in running, and just there is the risk of leakage of oil at the seal ring place in four holes, valve mechanism cover side.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and the positioning device that on a kind of diesel engine, oil sprayer is installed is provided, make oil sprayer setting angle be able to accurate location, facilitate the installation of valve mechanism cover, also solve the risk of the seal ring place leakage of oil in four holes, valve mechanism cover side simultaneously.
Technology solution of the present utility model is as follows:
The positioning device that on a kind of diesel engine, oil sprayer is installed, comprise the cylinder head be arranged on cylinder, cylinder head is provided with several oil sprayers, oil sprayer forms oil-feed arm, cylinder head is mounted with positioning baffle, positioning baffle is by cross bar, vertical rod and block composition, cross bar forms some vertical rods, the top of vertical rod forms the block extended to cross bar side, one sidewall of block forms inclined-plane, the oil-feed arm rest of oil sprayer is on the inclined-plane of positioning baffle, the two ends of described cross bar form pin-and-hole, locating stud is plugged in cylinder head through the pin-and-hole of cross bar, described oil sprayer is bolted in cylinder head by injector plate and injector plate.
Described injector plate is pressed against on oil sprayer, and injector plate bolt is fastened in cylinder head through injector plate.
Described oil sprayer Vertical Uniform is distributed in cylinder head, and the number of oil sprayer is identical with the vertical rod number on positioning baffle, and vertical rod is evenly distributed on cross bar.
Block on described positioning baffle is located at the same side of cross bar, and the inclined-plane on block is positioned at the sidewall direction of block homonymy.
The beneficial effects of the utility model are:
1, it is fastening again after adopting the positioning device of new structure to position oil sprayer, thus makes oil sprayer setting angle be able to accurate location, facilitates the installation of valve mechanism cover, also solves the risk of the seal ring place leakage of oil in four holes, valve mechanism cover side simultaneously.
2, this positioning device structure is simple, easily manufactured, and cost of production is low, and can reuse.
3, adopt this positioning device to position oil sprayer, fix and dismantle efficient and convenient, the packaging efficiency of diesel engine can be improved.
