Description
Technical field
The utility model relates to engine electric-controlled management system, specifically relates to a kind of air supply selecting arrangement for electrical control natural gas engine.
Background technique
For electric-controlled natural gas engine, engine management system mainly comprises the computer control module, the power-supply system that links to each other with the input end of computer control module, and the power unit that links to each other with computer control module output terminal, the employed combustion gas of motor is the makings of single appointment source of the gas, must not change.
Rock gas has well-known plurality of advantages as alternative motor fuels, and it is a kind of containing at underground hydrocarbon inflammable gas, and its source mainly contains four kinds: the reservoir gas of exploiting out from gas well, i.e. pure natural gas; The associated gas of following oil to exploit out together; The gas condensate field gas that contains the oil light ends; The coal mine gas of under mine, extracting out the coal seam.The composition of rock gas is quite complicated, and the component difference is very big, the rock gas that different regions, different pit mining come out, and composition and quality thereof are all inequality.Find that through years of researches the difference of its composition is little to the influence of general industry industry, but for the performance of natural gas used for automobile motor suitable influence is arranged still.For an electric-controlled natural gas engine, the result of its coupling is directed to a certain source of the gas makings specially, if when using the makings of another kind of source of the gas, this motor can't reach its performance design index, even might cause its work abominable.Therefore, guaranteeing under the constant substantially prerequisite of engine performance, also wanting to use the makings of different sources of the gas just can make product more adapt to the user flexibly.
Summary of the invention
The technical problems to be solved in the utility model is can use the different fuel source of the gas for same natural gas engine.A kind of air supply selecting arrangement for electrical control natural gas engine is provided, even the combustion gas difference, motor also can run well under the prerequisite that satisfies the performance design index, satisfies user's different demands.
The technical solution of the utility model is achieved in that the utility model motor source of the gas selection device mainly comprises the computer control module, the power-supply system that links to each other with the input end of computer control module, and the power unit that links to each other with computer control module output terminal, simultaneously, the input end of computer control module also is connected with the source of the gas selector switch.
The source of the gas selector switch comprises two or more gears, the corresponding respectively different input ends that are connected the computer control module of different gears.
Below, by description the utility model is described further function.
Input end with computer control module of multiple parameter correction and matching and calibration collection of functions is connected with the source of the gas selector switch, when needs use the combustion gas different with original source of the gas makings, select corresponding switch gear according to the index of source of the gas makings, at this moment, the calibration function collection control executive component of the computer control module by source of the gas selector switch correspondence.
In sum, the beneficial effects of the utility model are as follows:
The utility model natural gas engine air supply selecting arrangement, the input end of computer control module connects the source of the gas selector switch, automatically select corresponding control program according to the different gears of selecting the source of the gas selector switch, make motor under different sources of the gas, can both satisfy the design objective running according to the data that match, therefore, after changing the source of the gas kind, do not need more to reengine, still can satisfy performance index, simultaneously, under the prerequisite that has satisfied user's gas diversification use, simple in structure, easy to operate, be easy to repacking to existing car load.
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
Description of drawings
Accompanying drawing is a motor source of the gas selection device structural representation.
