Embodiment
Below in conjunction with accompanying drawing 1-5, enforcement of the present utility model is described in further detail, but to those skilled in the relevant art, according to thought of the present utility model, all likely changes in specific embodiments and applications.So, this specification should be interpreted as restriction of the present utility model.Any change under the restriction of the utility model basic thought all belongs within the utility model category, and scope of patent protection of the present utility model should be limited by claim.
As Figure 1-3, described engine working process is as follows: during engine operation, when piston (26) come downwards to open suction port time, intake process starts.Fresh air arrives closure (16) after filter cleaner (19) and pressure stabilizing cavity (18), after a certain amount of machine oil is sprayed into closure (16) by the oil injection nozzle (23) after same subject throttle (16).Air and wellatomized machine oil mixture enter engine crankcase, first lubricate the motion in crankcase and cool, then by entering cylinder (27) with the intake duct of suction port UNICOM.When piston stroking upward enters compression process to closing porting rear engine, now machine oil air mixture lubricates the friction pair in cylinder.Meanwhile, the fuel air mixture of all set premix in air-fuel rail (6), this air fuel mixture provides pressurized air by air pump (13), fuel oil is sprayed into by fuel nozzle (5), when piston (26) goes upward to top dead center annex, fuel air mixture sprays into cylinder (27) through straight spraying nozzle (7), and at appropriate time after this, spark plug (8) is lighted a fire, motor enters combustion expansion process, promotes piston (26) descending acting.When piston (26) come downwards to open relief opening time, exhaust process starts until next intake process.Described above is complete job circulation of this motor.
As shown in Figure 4, when cylinder (27) inner carrier (26) runs to budc (BTDC) 155 °, the fuel nozzle (5) corresponding to this cylinder (27) starts fuel oil to be sprayed into air-fuel rail (6), this fuel nozzle (5) discharge time is determined by concrete engine operating condition, from 5 ° of crank angles to 50 ° of crank angles not etc.; When budc (BTDC) 80 °, straight spraying nozzle (7) is again by the air fuel mixture direct cylinder injection (27) in air-fuel rail (6), the discharge time of this straight spraying nozzle (7) is determined by concrete engine operating condition, from 5 ° of crank angles to 50 ° of crank angles not etc.; Light a fire when straight spraying nozzle (7) starts the appropriate time after spraying, concrete time of ignition from spray after 3 ° of crank angles to 10 ° of crank angles not etc.
Motor described in the utility model fuel oil and air pressure all at below 10bar time the Sauter mean diameter of various injected fuel spray just can be made to reach less than 10 microns, and well-known ordinary straight injection diesel engine can make Sauter mean diameter reach the magnitude of 10 microns when the jet pressure up to more than 1600bar, such one side just greatly reduces the requirement of motor for oil-fired system, make spraying diffusion mixing process more rapid on the other hand, make the liquid fuels such as diesel oil, aviation kerosine and gasoline can both realize ignition combustion on described motor.The mode of lighting can increase substantially engine speed, improve specific power, alleviate engine weight, (comparing with the compression ignition engine such as conventional diesel and kerosene engine), these advantages are for most important unmanned plane and outboard machine application.
As shown in Figure 5, in the air pump drive system of motor described in the utility model and fuel oil supply system, the pressurized air of described system is provided by a little plunger-type air pump (13), and it can be driven by an eccentric air pump drive plate (24) be arranged on bent axle.Fresh air after the filtration that crankcase flows into is inhaled in plunger cavity by air pump gas-entered passageway, because described drive plate (24) is eccentric design, therefore the motor described drive plate (24) that often turns around all can make air pump plunger to-and-fro motion once, thus by the air compressing in plunger cavity.Air after compression is subsequently by sending into air-fuel rail (6) (air pump outlet is connected by pipeline with suction tude) at a butterfly valve of air pump head and air pump outlet.This design does not need separately for air pump provides belt, belt pulley, compressor rod-crankshaft, intake valve, suction tude and air intake filter.By avoiding designing these unwanted component, cause system and succinct, exquisite and low cost, and can be fabulous meet engine performance requirement.Described system and air-fuel rail (6), fuel pump (3), fuel nozzle (5), straight spraying nozzle (7) constitute the fuel oil supply system (working principle as Fig. 4 accompanying drawing illustrate as described in) of motor described in model utility jointly.The major character of fuel oil supply system:
1) the fabulous atomization (average Suo Te diameter is less than 10 microns) by using the pressurized air of low pressure to reach fuel oil;
2) inflammable mixture be formed in cylinder can be accelerated;
3) a small amount of air owing to spraying, insensitive to the residual gas of a circulation upper in cylinder;
4) the uncorrelated control of independence that fuel oil sprays and mixture sprays, this is performed by fuel nozzle (5) and straight spraying nozzle (7) respectively.This feature can bring a series of benefit, comprising: the flexibility improving fuel oil mixture form, insensitive to the extreme of carbon distribution, reduce system cost etc.
Finally, not deviating from the scope of this claim, can clearly find out described by the utility model start function to be modified or change.
