Technical field
The utility model relates to a kind of gas engine peculiar to vessel, and in particular, it is automatically controlled by cylinder order fuel injection system that the utility model relates to a kind of gas engine multiple spot peculiar to vessel.
Background technique
In order to reach the purpose of energy-conserving and environment-protective, the fuel of all kinds of in the world advanced technology motors sprays, and all adopts multiple spot automatically controlled by cylinder order fuel injection techniques, and gas engine peculiar to vessel also should be like this.
Yet, at present at home in being provided with of marine engine gaseous fuel supply mode, still adopt Carburetor negative pressure inhalation type structure.This shortcoming that existence is set is: be difficult to make power index, exhaust index and reliability index to reach standard-required.
The model utility content
Problem to be solved in the utility model overcomes the defective of prior art exactly, and provides a kind of novel gas engine multiple spot peculiar to vessel automatically controlled by cylinder order fuel injection system for this reason.
The technical solution of the utility model is:
A kind of gas engine multiple spot peculiar to vessel is automatically controlled by cylinder order fuel injection system, comprise the feeding pipe that the pressure stabilizing cavity that is provided with closure and one end and described pressure stabilizing cavity are communicated with and evenly arrange, the other end of described feeding pipe connects cylinder head, described feeding pipe is provided with fuel orifice, and described fuel orifice is between the intake valve of described closure and described cylinder head.
Distance≤the 20mm of described fuel orifice and described intake valve.
The angle of inclination of described fuel orifice is straight bottom line with the tube wall of described feeding pipe, with described intake valve direction angle at 45, becomes 15 ° of angles with the tangent direction of air whirl in the described feeding pipe.
The diameter of described fuel orifice and the scaling factor of discharge capacity are 0.2 ± 0.02.
The pressure that fuel sprays is 1.4Kg-2.5Kg.
The air supply system of described fuel orifice adopts two decompressor gas making structures.
The beneficial effects of the utility model are:
(1) can make the fuel of injection under the situation that cooperates ECU to control at regular time and quantity, obtain better mixing, thereby reduce the negative effect of fuel jet flow with air.
(2) can make the fuel of injection the shortest, thereby reach optimum timeliness to the path of intake valve.
(3) can make power index, exhaust index, reliability index all be better than the fuel supply system of carburetor type.
(4) can stop system's frosting, guarantee the low-temperature cool starting performance, eliminate flame-out phenomenon of the transitional period of idling lotus when loading load.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Fig. 2 is a schematic diagram of the present utility model.
Embodiment
For the easier quilt of content of the present utility model is clearly understood, the technical solution of the utility model is done to describe in detail below in conjunction with accompanying drawing and embodiment.
In order to realize the technical purpose of this programme, the utility model is according to different engine model, discharge capacity, at the intake valve of each cylinder intake pipeline to the spray-hole that is provided with different-diameter, diverse location between the closure, form best tangential angle with the jet that fuel was produced that guarantees the ejection of described air inlet pipeline to greatest extent and the air swirl of inspiration, thus reach quicken to mix, in order to the technique effect of optimized combustion.
As shown in Figure 1, gas engine multiple spot peculiar to vessel of the present utility model is automatically controlled by cylinder order fuel injection system, comprise the feeding pipe 3 that the pressure stabilizing cavity 2 that is provided with closure 1 and one end and described pressure stabilizing cavity 2 are communicated with and evenly arrange, the other end of described feeding pipe 3 connects cylinder head, described feeding pipe 3 is provided with fuel orifice 4, and described fuel orifice 4 is between the intake valve 5 of the closure 1 of described pressure stabilizing cavity 2 and described cylinder head.
The utility model each parts operation in taking into full account gas engine peculiar to vessel does not have under the situation of interfering, and the position of described fuel orifice 4 is set.The result of test of many times is:
The described intake valve 5 of described fuel orifice 4 distances is near more good more, generally speaking, the setting of this distance with≤20mm is good;
The angle of inclination of described fuel orifice 4 is straight bottom line with the tube wall of described feeding pipe 3, with the direction shape angle at 45 of described intake valve 5, and with described feeding pipe 3 in the tangent direction of air whirls form 15 ° of angles.The effect that sprays into of this set-up mode is: can quicken fuel and Air mixing, and form certain ram effect.
The diameter of described fuel orifice 4 and the scaling factor of discharge capacity are good with 0.2 ± 0.02, and the jet pressure of its fuel is good with 1.4Kg-2.5Kg.Such setting can guarantee the good combustion after the gas blowing, thereby reach the energy-saving and environmental protection purpose.
In schematic diagram shown in Figure 2, described motor connects cooling-water temperature sensor, partly the decline resistance of value of the described cooling-water temperature sensor water temperature signal of can delaying time 3-5 minute and can guarantee in parallel.The effect of this setting be to make described engine control system guarantee the fuel injection pulsewidth operation that reduces by half in aforesaid 3-5 minute, thereby the cancellation legacy system is downloaded to the enriching program of loaded transition stage usually from idling.Simultaneously, on the fuel orifice 4 that is arranged at described feeding pipe 3, connect the electrically-controlled valve of normal close type, and make the other end of described electrically-controlled valve connect first, second decompressor, thereby constitute a two decompression gas making structure.The effect of this setting, be make described electrically-controlled valve when energising disconnects according to the control command burner oil.
