Accompanying drawing explanation
Fig. 1 is the layout schematic diagram of the detection device according to electric-controlled fuel injector of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1, according to the detection device of a kind of electric-controlled fuel injector of the specific embodiment of the invention, comprise fuel tank 1, high voltage stabilizing case 2, high-pressure service pump 3 and photographic camera and measuring device (not shown).Fuel oil wherein in fuel tank 1 is delivered in high voltage stabilizing case 2 by high-pressure service pump 3, high voltage stabilizing case 2 is provided with high-pressure oil pipe 21, this high-pressure oil pipe 21 is used for being communicated with the filler opening of electric-controlled fuel injector 6 to be detected, during detection, high voltage stabilizing case 2 is used for providing the fuel oil of constant voltage to electric-controlled fuel injector 6, circuit controller 4 is used for controlling the energising of electric-controlled fuel injector 6, power-off and energising duration, and photographic camera is used for taking the oil spout bundle of electric-controlled fuel injector 6, and measuring device is used for collecting the fuel injection quantity of electric-controlled fuel injector 6.
In such scheme, fuel tank 1 is arranged on the bottom of detection device, it is seal container, with the filtrating equipment of fuel oil, for storing fuel oil, it is connected by oil pipe with high voltage stabilizing case 2 with high-pressure service pump 3, during high-pressure service pump 3 works, to be delivered in high voltage stabilizing case 2 after the fuel oil pressurization in fuel tank 1, the fuel oil in high voltage stabilizing case 2 be pressure constant state, for detecting with providing constant voltage fuel oil.
In addition, circuit controller 4 is electric current of voltage regulation control system, can control the energising of electric-controlled fuel injector 6 circuit, power-off and energising duration etc., thus controls unlatching, the closedown of electric-controlled fuel injector 6 and open duration etc.When detecting, need check that the wiring terminal of electric-controlled fuel injector 6 is connected with circuit controller 4, circuit controller 4 can set the time of power on circuitry, current"on"time length etc.After circuit controller 4 is connected, can be energized automatically to electric-controlled fuel injector 6 by setting value, thus control unlatching, the closedown of the needle-valve of electric-controlled fuel injector 6 and open duration etc., after electric-controlled fuel injector 6 is energized, needle-valve is opened, and high pressure fuel just ejects.Taken pictures by camera, the direction of oil spout bundle, shape, length, atomization quality etc. can be examined, by collection and the weighing calculating of the containers such as measuring cup, each size of spraying oil mass can be known.Coupled computer design aids and engine test test etc., can accelerate the progress of engine combustion exploitation and ensure that the new engine burning of exploitation is more efficient, discharge is better.
As a kind of preferred embodiment, high voltage stabilizing case 2 is provided with Decompression valves and pressure gauge 22.In the present embodiment, this high voltage stabilizing case 2, with pressure gauge 22, can read pressure value, and it is also with Decompression valves, and the meeting releasing pressure automatically when pressure exceeds permitted value, can realize the object keeping constant voltage like this.
As a kind of preferred embodiment, high voltage stabilizing case 2 is communicated with fuel tank 1 by return tube 23.In the present embodiment, return tube 23 is low pressure fuel pipes, pumps into the fuel oil after the excessive fuel oil of high voltage stabilizing case 2 and pressure release and all flows in fuel tank 1 by this return tube 23.
