Working principle of the present utility model is as follows: under normal operation, injection pump of engine provides fuel oil, flowing through high-pressure oil pipe enters in the fuel-displaced screw-threaded counterbore 160 of oil injector body 100 side, and fuel-displaced screw-threaded counterbore 160 is entered in pressure chamber 522 by the oiling passage 150 in oil injector body 100 and the inclined hole 525 in oil nozzle needle-valve body 520.Because Needle shaft 530 is subject to the downward spring-force driven dual of the oil nozzle spring 420 of push rod 300 upper end, the lower end of Needle shaft 530 is contacted with the entrance conical surface seal of needle valve hole 524, now, pressure chamber 522 is identical with the oil pressure of high-pressure oil pipe, when pressure chamber 522 oil pressure act on Needle shaft 530 hydraulic coupling be upwards greater than oil nozzle spring 420 downward spring force time, the spring force that Needle shaft 530 overcomes oil nozzle spring 420 downward moves upward, depart from the entrance of needle valve hole 524 and seal, needle valve hole 524 commencement of fuel injection.When pressure chamber 522 oil pressure act on Needle shaft 530 hydraulic coupling be upwards less than oil nozzle spring 420 downward spring force time, the spring-force driven dual that Needle shaft 530 is subject to the oil nozzle spring 420 of push rod 300 upper end downward moves downward, make the entrance of the lower end of Needle shaft 530 and needle valve hole 524 again conical surface seal contact.
When the engine operates, cryogenic liquid enters in the semi-circular cooling water channel 183 of oil injector body 100 circumference from engine coolant case, and by the radial cooling water channel 184 in oil injector body 100, the side of the cooling water channel 529 axially in cooled water channel 170 and oil nozzle needle-valve body 520 and the cooling cavities 528 of ring-type enters in the cooling cavities 528 of ring-type, take away oil injector body 100, after the heat that oil nozzle needle-valve body 520 distributes, by the opposite side of the cooling cavities 528 of ring-type, cooling water channel 529a in oil nozzle needle-valve body 520, the cooled water channel 170a of axis in oil injector body 100, radial cooling water channel 184a, semi-circular cooling water channel 183a flows out and flows back to refrigerating device refrigeration again.
The utility model is applicable to gently, heavy-duty diesel oil.While the utility model provides the fuel of high energy calorie value to big-block engine, ensure the continuous in commission reliability of motor.
High pressure fuel flows through high-pressure oil pipe from high-pressure oil pipe and enters in the fuel-displaced screw-threaded counterbore 160 of oil injector body 100 side, fuel-displaced screw-threaded counterbore 160 is entered into after in pressure chamber 522 by the oiling passage 150 in oil injector body 100 and the inclined hole 525 in oil nozzle needle-valve body 520, the spring force that Needle shaft 530 overcomes oil nozzle spring 420 downward moves upward, and departs from seal with the entrance of needle valve hole 524.When Needle shaft 530 1 leaves the entrance of needle valve hole 524, its pressure-bearing surface increases suddenly, Needle shaft 530 is risen fast, reduces restriction loss, makes fuel oil spray into cylinder through needle valve hole 524 decidedly.After Injection Pump fuel cut-off, the oil pressure in pressure chamber 522 reduces suddenly, and Needle shaft 530 is closed rapidly under the effect of the downward spring force of oil nozzle spring 420, and oil spout just stops absolutely, and now Needle shaft 530 separates high pressure oil space and firing chamber, and oil sprayer terminates.
The utility model adopts circulating cooling mode to heavy oil sprayer cooling itself, and this structure effectively can improve the reliability of oil sprayer, ensures the stability of each oil spout of oil sprayer.Fixed quantity can be realized spray.
