Wherein, the particularly horizontally-opposed piston of two-stroke, opposed-cylinder engine has following two advantages:
1, agent structure compact (axial dimension and the relatively conventional same power engine of total height are little)；2, its energy
Metric density can reach the high-tech water bottle (>=90kW/L, >=1.9kW/kg) of same domain；Because this is two big
Advantage and by the same industry attract attention.
The effect of engine fuel injector is according to in-cylinder combustion requirement, by fuel oil with suitable injection pressure,
Suitably spray pattern and appropriate spray angle and penetration degree sprays into combustor, and opens in the regulation moment
With stopping oil spout.Owing to the horizontally-opposed piston of two-stroke, opposed-cylinder engine do not have conventional engines
The end cap being had, simultaneously as the fuel oil that the horizontally-opposed piston of two-stroke, opposed-cylinder engine are special
Cell structure so that the oily Shu Wufa of traditional fuel injector ejection is suitable for the horizontally-opposed piston of two-stroke, opposed
Cylinder engine.
Summary of the invention
The problems referred to above existed for prior art, this utility model aims to provide a kind of opposed work of two-stroke
Plug opposed-cylinder engine fuel oil injector bundle so that it is can eject be applicable to the horizontally-opposed piston of two-stroke,
The fuel oil injector bundle of opposed-cylinder engine.
Concrete technical scheme is as follows:
A kind of two-stroke opposed piston opposed-cylinder engine fuel oil injector bundle includes: cylinder sleeve, outer piston,
And inner carrier；Wherein, cylinder sleeve be symmetrically arranged on two with an installing hole, be mounted on one in two installing holes
Fuel injector；Further, cylinder sleeve, outer piston and inner carrier constitute combustor；The central axis of two fuel injectors is just
Central axis to combustor.
Further, " V "-shaped projection in the middle part of the bottom section of outer piston.
Further, the top entirety of inner carrier is arranged in deep groove structure, and the middle part of inner carrier is provided with
One projection, the axial plane cross section of crossing at inner carrier top is arranged in " ω " font.
Further, fuel injector is provided with atomizer, and atomizer is that two pore structures are arranged.
Further, the axis of pitch of in fuel injector sprays into combustor two oil bundles and cylinder sleeve respectively in
6 ° and 22 ° of angles.
Further, the longitudinal axis of in fuel injector sprays into combustor two oil bundles and cylinder sleeve respectively in
12 ° and 21 degree of angles.
Compared with prior art, the two-stroke opposed piston opposed-cylinder engine spray that this utility model provides
Oil device oil bundle makes the oil bundle of ejection enter directly in combustor, and fuel oil can be made preferably to gasify, so that
Fuel oil preferably mixes with the air entered from air intake duct, the utility model has the advantage of: make fuel injector
Eject the fuel oil injector bundle being applicable to the horizontally-opposed piston of two-stroke, opposed-cylinder engine, and,
Improve the situation of burning Indoor Combustion, thus increase two-stroke horizontally-opposed piston opposed-cylinder engine

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained on the premise of not making creative work, broadly falls into
The scope of this utility model protection.
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as this reality
With novel restriction.
Fig. 1 is the two-stroke opposed piston opposed-cylinder engine spray provided in embodiment of the present utility model
The topology view of oil device oil bundle；As it is shown in figure 1, the two-stroke opposed piston provided in the present embodiment is opposed
Cylinder engine fuel oil injector bundle includes: cylinder sleeve 1, outer piston 2, inner carrier 3 and fuel injector 4,
Wherein, cylinder sleeve 1 be symmetrically arranged on two with an installing hole (not shown), be respectively mounted in two installing holes
There is a fuel injector 4, and, cylinder sleeve 1, outer piston 2 and inner carrier 3 constitute combustor 5；Two fuel injectors
