Description
[technical field]
The utility model relates to technical field of engines, is specifically related to a kind of unmanned plane displacement gasoline engine Electronic fuel injection device.
[background technique]
Petrol engine is using gasoline as fuel, thermal energy is become kinetic energy device.Because gasoline viscosity is little, evaporation is fast, with gasoline injection system, gasoline can be sprayed into cylinder, after the temperature and pressure that overcompression reaches certain, by spark ignitor, make gas expansion for doing work.The feature of petrol engine is that rotating speed is high, structure is simple, quality is light, cheap, petrol engine was increasingly extensive in the use of unmanned plane industry in recent years for smooth running, easy maintenance, the mode of the natural aspiration carburetor engine that tradition adopts exposes a lot of defect, as fuel consume is high, disadvantage that rotary speed unstabilization is fixed etc., and engine behavior instability causes aerial flame-out air crash accident, have a strong impact on the flight safety that unmanned plane is being executed the task, cause heavy losses to user.My department of comprehensive above defect goes out through thousands of secondary testing research, is applicable to the electronic fuel injection system that unmanned vehicle engine uses.
[model utility content]
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, reasonable in design, a kind of unmanned plane displacement gasoline engine Electronic fuel injection device easy to use, it adopts and controls engine oil inlet amount with computer (ECU), engine interior burning is initiatively entered to oil supply system pressurization through control fuel injection mouth by Squirtpump special, solve motor because of oil inlet quantity instability cause aerial flame-out, and by fuel controller (ECU) accurate adjustment oil inlet quantity, make combustion efficiency higher, reduce fuel consume through quiet car test with the motor of traditional natural suction carburetor and reach 40 percent, when considerably increasing the boat of unmanned plane, decrease aerial flame-out probability.
A kind of unmanned plane displacement gasoline engine Electronic fuel injection device described in the utility model, it comprises the carburetor throttle transform interface be arranged on engine main body, this carburetor throttle transform interface is provided with oil nozzle and oil inlet quantity servomechanism, this oil nozzle is arranged a solenoid valve, this solenoid valve is connected with oil pump by fuel supply line, and this oil pump is connected with fuel tank; Oil inlet quantity servomechanism on described engine main body is connected with relay with fuel controller respectively by data conductor assembly.
After adopting said structure, the utility model beneficial effect is: a kind of unmanned plane displacement gasoline engine Electronic fuel injection device described in the utility model, it adopts and controls engine oil inlet amount with computer (ECU), engine interior burning is initiatively entered to oil supply system pressurization through control fuel injection mouth by Squirtpump special, solve motor because of oil inlet quantity instability cause aerial flame-out, and by fuel controller (ECU) accurate adjustment oil inlet quantity, make combustion efficiency higher, reduce fuel consume through quiet car test with the motor of traditional natural suction carburetor and reach 40 percent, when considerably increasing the boat of unmanned plane, decrease aerial flame-out probability.
[accompanying drawing explanation]
Accompanying drawing described herein is used to provide to further understanding of the present utility model, forms a application's part, but does not form improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation;
Description of reference numerals:
1, engine main body; 2, carburetor throttle transform interface; 3, oil pump; 4, fuel supply line; 5, relay; 6, data conductor assembly; 7, fuel controller.
[embodiment]
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in Figure 1, a kind of unmanned plane displacement gasoline engine Electronic fuel injection device described in this embodiment, it comprises the carburetor throttle transform interface 2 be arranged on engine main body 1, this carburetor throttle transform interface 2 is provided with oil nozzle and oil inlet quantity servomechanism, this oil nozzle is arranged a solenoid valve, this solenoid valve is connected with oil pump 3 by fuel supply line 4, and this oil pump 3 is connected with fuel tank; Oil inlet quantity servomechanism on described engine main body 1 is connected with relay 5 with fuel controller 7 respectively by data conductor assembly 6.
In the utility model, the design is grouped into by carburetor throttle transform interface, oil nozzle, oil inlet quantity servomechanism, fuel controller (ECU), oil pump, fuel supply line, fuel tank.Original Carburetor is dismantled carburetor throttle transform interface is installed, oil nozzle and oil inlet quantity servomechanism are arranged on carburetor throttle transform interface, servomechanism connects fuel controller (ECU), sends action executing instruction thus control oil inlet quantity more accurately by fuel controller to servo.
Working principle of the present utility model is: enter into solenoid valve by oil pump oil suction from fuel tank by oil pipe, control servomechanism amounts of rotation by ECU (fuel controller) and regulate closure open angle, Auto-matching oil inlet quantity signal, to solenoid valve, to be performed an action the corresponding adjustment oil inlet quantity of signal by solenoid valve.The effect of the utility model repeat circuit is the switch of control oil pump.
A kind of unmanned plane displacement gasoline engine Electronic fuel injection device described in the utility model, it adopts and controls engine oil inlet amount with computer (ECU), engine interior burning is initiatively entered to oil supply system pressurization through control fuel injection mouth by Squirtpump special, solve motor because of oil inlet quantity instability cause aerial flame-out, and by fuel controller (ECU) accurate adjustment oil inlet quantity, make combustion efficiency higher, reduce fuel consume through quiet car test with the motor of traditional natural suction carburetor and reach 40 percent, when considerably increasing the boat of unmanned plane, decrease aerial flame-out probability.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
