Fuel injector briquetting of the present utility model arranges position by adjusting hold-down bolt hole 11 in the first main body 15 of the first sub-block 1, so that the first sub-block 1 meets the thrust demand of fuel injector 2.
Owing to the thrust of fuel injector 2 has certain value range requirement. Such as: the thrust suffered by each fuel injector 2 preferably must be held between 9MPa to 16MPa. If the thrust suffered by each fuel injector 2 is less than 9MPa, then fuel injector 2 is made to press not tight, it is easy to shake; If the thrust suffered by each fuel injector 2 is more than 16MPa, it is easy to the damage that deforms by fuel injector 2 conquassation. Three fuel injectors in three-cylinder engine of the prior art adopt a single-body type fuel injector briquetting and a fuel injector briquetting, hold-down bolt hole (be namely fixed and clamped bolt point) on single-body type fuel injector briquetting and fuel injector briquetting is respectively positioned on the center on its length direction, can cause that the fuel injector 2 being positioned at middle part bears the thrust that two hold-down bolts 3 apply. Such as, single-body type fuel injector briquetting is identical with the total length of fuel injector briquetting, 18MPa thrust is applied respectively when being pointed to two two hold-down bolts 3 being fixed and clamped in bolt point, then the fuel injector 2 at two ends is respectively subjected to the thrust of 9MPa, and the fuel injector 2 of center will bear the thrust of 18MPa, the thrust demand of fuel injector 2 cannot be met, make fuel injector 2 conquassation of center and the damage that deforms.

Referring to Fig. 3, when two hold-down bolts 3 being positioned at two hold-down bolt holes 11 apply 18MPa thrust respectively, due to equalising torque, then thrust suffered by each fuel injector 2 is 12MPa, meets the thrust demand of fuel injector 2. Meet three fuel injectors 2 simultaneously and adopt the mounting means of two identical sub-blocks.
Specifically, the total length assuming the first sub-block 1 and the second sub-block 5 is 30mm, hold-down bolt 3 applies the pressure of 18MPA, assuming to be positioned at the thrust that the fuel injector 2 of left end bears is XMPa, the thrust that centrally located fuel injector 2 bears is YMPa, forms moment conditions formula and is: X*10=Y*20X+Y=18, then X=12MPaY=6MPa, so the thrust that the fuel injector 2 being positioned at left end bears is 12MPa, the thrust that centrally located fuel injector 2 bears is 6MPa. Certainly, the relational expression between the fuel injector 2 of right-hand member and centrally located fuel injector 2 is also by that analogy.Showing that the thrust that the fuel injector 2 being positioned at right-hand member bears is 12MPa, the thrust that centrally located fuel injector 2 bears is 6MPa. What bear due to centrally located fuel injector 2 is two parts of thrusts, so the fuel injector 2 of centre bears thrust also for 12MPa. Fuel injector briquetting of the present utility model can make full use of the relation between pressure demand and power and the moment of fuel injector 2, makes the first sub-block 1 and the second sub-block 5 meet the instructions for use of three fuel injectors 2.
On the width of the first sub-block 1, namely on the fore-and-aft direction of the first sub-block 1 shown in Fig. 4, hold-down bolt hole 11 is centrally located on the middle separated time of the first sub-block 1, and the rear and front end uniform force on the width of the first sub-block 1 making the first sub-block 1 is consistent. Meanwhile, it is capable to that determines hold-down bolt hole 11 arranges position, in the first main body 15 of the first sub-block 1, it is precisely carried out punching to facilitate. Owing to the first sub-block 1 and the second sub-block 5 are of similar shape and size, so, second main body 53 of the second sub-block 5 also offers hold-down bolt hole, and the requirement arranging position in hold-down bolt hole is consistent with the requirement arranging position in the hold-down bolt hole 11 in the first sub-block 1.
Referring to Fig. 4, the first main body 15 of the first sub-block 1 is connected in rounding off mode with two presser feets (i.e. the first presser feet 13) of the first sub-block 1. First main body 15 is connected in rounding off mode with the first connecting pin 14 and the second connecting pin 16. Concentrating thus being prevented effectively from stress, while using less material, ensure that the intensity of the first sub-block 1. Similarly, owing to the first sub-block 1 and the second sub-block 5 are of similar shape and size, so, the second main body 53 of the second sub-block 5 is connected in rounding off mode with two presser feets (i.e. the second presser feet 51) of the second sub-block 5. Second main body 53 is connected in rounding off mode with the 3rd connecting pin 52 and the 4th connecting pin 54.
