Specific embodiment
The purpose of this utility model is described in further detail below by specific embodiment, embodiment cannot be herein
It repeats one by one, but therefore the embodiments of the present invention is not limited to the following examples.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of double atomizer oil supply systems of put-put, including main jet
Oil nozzle 1, main fuel spray nozzle support 2, secondary atomizer 3, secondary atomizer support 4, air inlet resonant cavity 5, fuel tank 6, built-in oil pump 7, oil transportation
Pipe 8, the air inlet resonant cavity 5 include the air throttle for adjusting engine load, and the petroleum pipeline 8 includes for adjusting fuel oil
The pressure regulator valve of pressure, the fuel tank 6 include the fuel filter and strainer for filter fuel impurity.
In order to reduce manufacturing cost and guarantee reliability, the main fuel spray nozzle 1 and secondary atomizer 3 are 12 hole big flow oil spouts
Mouth.The main fuel spray nozzle 1 is arranged in inlet manifold end by the main fuel spray nozzle support 2, and secondary atomizer 3 passes through secondary oil spout
Mouth support 4 is arranged on resonant cavity.The main fuel spray nozzle support 2 and secondary atomizer support 4 are aluminium Milling Machinings.The resonant cavity
5 are made with carbon fibre material.Fuel oil after the pressurization of built-in oil pump 7 can be transported to two oil spouts by the petroleum pipeline 8
Mouth, while remaining fuel oil can be flowed back into fuel tank 6 by return pipe.
In order to which the design for meeting raising gas handling system volumetric efficiency and improve fuel spray rate and then raising efficiency of combustion is wanted
It asks, the main fuel spray nozzle 1 and main fuel spray nozzle support 2 are arranged in inlet manifold end, secondary atomizer 3 and secondary 4 cloth of atomizer support
It sets on resonant cavity.Common manifold fuel injection is that atomizer is arranged in the opposite position in the inlet valve back side, is for side
Just increase the condensation rate of fuel oil using the heat at the inlet valve back side, but in cold start-up, the fuel spray rate of the atomizer is very
Difference, so that burning very severe, so that being short of power, and emission performance is very poor, cold start-up is difficult.The present embodiment it is excellent
Point is that intake air temperature can sufficiently be reduced by setting atomizer, promote density of the induced air, reduces pinking tendency, can also promote engine and turn
A fast section fuel-injected transient response ability of quickly climbing, makes gasoline form oil film, the time of air-fuel mixture in air inlet inside pipe wall
It lengthens, so that condensation rate increases, to improve the power of engine.By experimental analysis, pass through the air inlet on resonant cavity
The analysis of data that pressure-temperature sensor measures, after opening secondary atomizer 3, intake air temperature is declined, admission pressure on
It rises, reaches design effect.
In order to sufficiently improve efficiency of combustion and air intake duct be avoided to generate excessive oil film, air-fuel ratio overrich is caused to cause to start
The case where machine power declines needs through electronic control unit according to different Operating condition adjustment main fuel spray nozzles 1, secondary atomizer 3
Oil spout ratio is concluded that secondary atomizer 3 should suddenly accelerate revolving speed ramp-up period and high revolving speed after consulting relevant materials
High load capacity operating condition uses, and load low-load region should be reduced in right amount in high revolving speed, this belongs to anxious braking section, it should subtract
Few oil film amount improves fuel economy.
The above embodiments of the present invention is merely examples for clearly illustrating the present invention, and is not
Limitations of the embodiments of the present invention.For those of ordinary skill in the art, on above explained basis
On can also make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.
Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in this reality
Within novel scope of protection of the claims.
