Abstract
The invention discloses an engine oil sprayer base connecting system. An oil sprayer is hermetically connected and fixed with a cylinder cover by using a large bolt through an oil sprayer pressure plate on an oil sprayer base; meanwhile, the oil sprayer base is connected and fixed with the cylinder cover through the large bolt; the cylinder cover is provided with hollow cavities of which the appearances are the same as those of oil sprayer bases according to the quantity of the oil sprayers; the oil sprayer base is connected and fixed with the cylinder cover through three small bolts; a high-pressure oil pipe which is connected with the oil sprayer, a small oil return pipe and an electric control wiring harness are arranged outside the cylinder cover; and the oil sprayer base is sealed together with the cylinder cover through a sealing rubber ring. The oil sprayer is fixed skillfully through a reasonable design, and meanwhile, the high-pressure oil pipe which is connected with the oil sprayer, the small oil return pipe and the electric control wiring harness are arranged outside the cylinder cover, so that great convenience is brought to assembly of the entire machine and after-sale service on the basis of effectively reducing the height of the cylinder cover, and the maintaining cost is lowered.
Description
Technical field
The invention belongs to engine component, be specifically related to a kind of oil injector seat connected system of motor.
Background technique
Well-known countries in the world are at present paid much attention to environmental protection; So the emission standard to motor-vehicle tail-gas is also strict day by day; Manage the two-air valve engine exhaust emission standard improved through technological improvement and be not long-term plan, so produce the emphasis that four-valve engine will become manufacturing firm.As the oil sprayer of diesel engine vitals, general upright being installed in the middle of the cylinder cap, the outside is coated with cylinder head cover.Oil sprayer will be connected with high-pressure oil pipe, little return tube, the automatically controlled wire harness of oil sprayer etc., because component are more, its installation and maintenance are all very inconvenient, also relate to the sealing problem between lubricating oil pipeline and the cylinder head cover simultaneously.The present invention proposes a novel oil injector seat in view of the above, makes the attachment portion of oil sprayer and high-pressure oil pipe, little return tube, wire harness etc. all place the outside of rocker arm chamber cover.Installation, maintenance and the sealing problem of component all are resolved, also reduce the height of cylinder head cover simultaneously significantly.
Summary of the invention
The object of the invention provides a kind of new work engine oil injector seat connected system, is improving on the motor installation efficiency basis, for the after-sales service of motor provides convenience.
Know-why of the present invention and scheme are following: engine fuel injector seat connected system comprises: oil sprayer, injector plate, cylinder head cover, oil injector seat, return tube and high-pressure oil pipe etc.Oil sprayer is sealedly connected and fixed with a king-bolt and cylinder cap through the injector plate on the oil injector seat, and oil injector seat also is connected fixing through this king-bolt with cylinder cap simultaneously.Cylinder head cover has the hole identical with the oil injector seat profile according to the number of oil sprayer; Oil injector seat is connected fixing with cylinder head cover through three stove bolts; The high-pressure oil pipe that is connected with oil sprayer, little return tube and automatically controlled wire harness place the outside of cylinder head cover, seal through O-ring seal between oil injector seat and the cylinder head cover.
Oil injector seat is connected with cylinder cap through a bolt, and bolt is fixed on injector plate on the oil injector seat simultaneously, and oil injector seat links together through three bolts and cylinder head cover again simultaneously.
Characteristics of the present invention and beneficial effect are; Through rational design; Oil sprayer is carried out fixing cleverly, and the high-pressure oil pipe that meanwhile will be connected with oil sprayer again, little return tube and automatically controlled wire harness have been placed on the outside of cylinder head cover, on the basis that effectively reduces the cylinder head cover height; For final assembly and after sales service provide great convenience, reduced maintenance cost again.
Description of drawings
Fig. 1 is provided with scheme of installation for parts of the present invention.
Fig. 2 is each the bolt hole location dimension explanation of embodiment of the invention oil injector seat.
Embodiment
Below in conjunction with accompanying drawing and through specific embodiment principle of the present invention and structure are done further explanation.
Engine fuel injector seat connected system, its structure is: oil sprayer 1 is sealedly connected and fixed through king-bolt of 2 usefulness of the injector plate on the oil injector seat 53 and cylinder cap, and oil injector seat 5 also is connected fixing through king-bolt 3 with cylinder cap simultaneously.Cylinder head cover 4 has and the identical hole of oil injector seat 5 profiles according to the number of oil sprayer, and oil injector seat is connected fixing with cylinder head cover through three stove bolts 6.The high-pressure oil pipe 7 that is connected with oil sprayer, little return tube 8 and automatically controlled wire harness place the outside of cylinder head cover, seal through O-ring seal between oil injector seat and the cylinder head cover.
Oil sprayer is through injector plate and cylinder cap fixing its bolt hole of bolt and oil injector seat centre distance H4=28mm, and three stove bolt hole location dimensions that cylinder head cover and oil injector seat are fixed are in Vertical direction: first bolt hole and oil sprayer centre distance H1=17.24mm; Second bolt hole and oil sprayer centre distance H2=25.58mm; The 3rd bolt hole and oil sprayer centre distance H3=13.84mm; In the horizontal direction: first bolt hole and oil sprayer centre distance H6=15.67mm; Second bolt hole and oil sprayer centre distance H7=19.28mm; The 3rd bolt hole and oil sprayer centre distance H5=24.53mm, the height of oil injector seat is H8=62mm.
The surface of contact of surface of contact, oil injector seat and cylinder head cover that the surface of contact of mounting hole of oil sprayer and cylinder cap, oil injector seat and cylinder cap are fixing is equipped with sealing rubber ring, prevents that machine oil from oozing out.
