Abstract
The utility model relates to a fueling injection equipment of a diesel engine for being mounted on a cylinder cap of the diesel engine, mainly employing that the fuel injector is mounted in the center of the cylinder and positioned and pressed tightly by a diesel engine pressboard, an oil recess is made on the top board of the cylinder, a middle connection pipe is installed in the cylinder and connected with an oil inlet arranged on the fuel injector and is pressed on the cylinder cap. The utility model thoroughly prevents the mixing of fuel and lubricating oil, reducing the noise of the diesel engine, when a fuel-feed system of the diesel engine is transited to a common rail system, the cylinder cap structure, the fuel injector and an oil pipe are connected without alteration.
Description
Technical field:
The utility model relates to a kind of oil sprayer device of diesel engine, is used to be installed in the cylinder cap of diesel engine.
Technical background:
Before the utility model was made, in prior art, four-valve diesel engine oil sprayer and oil connection all were positioned at valve mechanism cover, and its adjustment, inspection, mounting or dismounting are all inconvenient.In case leaking, high-pressure oil pipe or return tube just be difficult in time find that the fuel oil that spills can cause more major break down to take place dilute lubricating oil.Because above-mentioned former be stranded adopts oil sprayer external outside valve mechanism cover usually, but this mode of structure is suitable difficulty to the four-valve diesel engine of medium and small cylinder diameter.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, thereby the installation of a kind of oil sprayer and oil pipe is provided and connects comparatively reliable, also thoroughly stopped simultaneously the possibility that fuel oil mixes with lubricant oil, it adjusts, checks, installs and removes the oil sprayer device of diesel engine eaily.
Main solution of the present utility model is achieved in that it mainly adopts oil sprayer 6 to be vertically mounted on cylinder axis, adopt injector plate 7 location to compress, on cylinder head 4 top boards, add an oblique oil pocket, middle adapter 10 is installed in the oil pocket, middle adapter 10 links to each other with filler opening on the oil sprayer 6, adopt cone match, middle adapter 10 is pressed on the cylinder head 4.
Description of drawings:
Fig. 1 is the utility model structural representation:
Embodiment:
The utility model adopts oil sprayer pad 1, oil sprayer copper sheathing 2 is housed outside oil sprayer 6, and oil sprayer 6 is vertically mounted on cylinder axis, locatees and compresses by the locating stud and the injector plate 7 of oil sprayer 6 end faces, and sealing adopts O type circle 3,5 to finish.Injector plate 7 fixing follower bolt 9, the spherical washers 8 of adopting are fixed on the cylinder head 4, and adopt the corner method to tighten, and guarantee the reliability of work.Oil sprayer 6 is connected by a middle adapter 10 with high-pressure oil pipe, being installed in its middle adapter 10 at oblique oil pocket of processing on cylinder head 4 top boards is connected with filler opening on the oil sprayer 6, taper is made on middle adapter 10 tops, and by cone match guarantee the sealing, middle adapter 10 is pressed on the cylinder cap 4 by middle gland nut 12, and adopts O shape circle 11 to seal.The oil return of oil sprayer 6 is by the slit of oil pocket, again on cylinder head 4 elongated spill port to the return tube that is connected on cylinder head 4 rear ends.
Compared with the prior art the utility model has the following advantages: 1, the installation of oil sprayer and oil pipe and connection are comparatively reliable, have also thoroughly stopped fuel oil simultaneously and have mixed with lubricant oil; 2, oil sprayer is in the cylinder cover of vibration isolation, noise reduction sound fully, has played reduction diesel engine noise; 3, when fuel system for diesel engine carries out the transition to common rail system, cylinder cap structure and oil sprayer, oil pipe connect need not changed.
Claims (3)
1, a kind of oil sprayer device of diesel engine, comprise cylinder head (4), oil sprayer (6), it is characterized in that adopting oil sprayer (6) to be vertically mounted on cylinder axis, adopt injector plate (7) location to compress, oblique oil pocket of processing on cylinder head (4) top board, middle adapter (10) is installed in the oil pocket, and middle adapter (10) links to each other with filler opening on the oil sprayer (6), and middle adapter (10) is pressed on the cylinder head (4).
2, the oil sprayer device of diesel engine according to claim 1 is characterized in that described middle adapter (10) top makes taper.
3, diesel engine fuel injecting apparatus according to claim 1 is characterized in that being shaped on spill port on the described cylinder head (4).
