Description
Technical field
The utility model relates to a kind of electricity field, specifically a kind of bavin oil and gas mixed combustion control system automobile oil door fuel limit device.
Background technique
Along with country put into effect continuously to vehicular emission administer requirement and restriction, new energy, clean energy resource are rapidly developed in the technical application of automotive fuel.It is one of development trend of China Diesel automotive fuel that diesel/natural gas dual-fuel mixes combustion.This technology on the basis of diesel engine, installs a set of use rock gas additional mix combustion system as the double fuel of combustion material, control automobile by diesel/natural gas mixed combustion control system to realize with rock gas being main fuel, using a small amount of diesel oil as the fuel supply mode ignited.Because this technology is changed little to original diesel engine, repacking cost is low, and in actual motion, diesel oil use amount reduces obviously, and tail gas blowdown declines to a great extent.This technology has obtained examination & approval and the support of government in some areas, enter the Market for refitting of diesel car.
Mixing in combustion system normal course of operation at diesel/natural gas dual-fuel, when vehicle stabilization runs, use if do not limit diesel oil, because there is the insufficient phenomenon of burning, the discharge of a large amount of pollutant be caused; When vehicle acceleration runs, for ensureing that the moment power of vehicle needs, the use of rock gas must be limited, recover the use amount to diesel oil.Above-mentioned situation, when being double fuel mixed combustion system cloud gray model, the situation that must process.
Summary of the invention
The purpose of this utility model is: provide a kind of bavin oil and gas mixed combustion control system automobile oil door fuel limit device, this device for auxiliary diesel/natural gas double-fuel mix combustion control system normally effectively run provide a set of feasible hardware device, to overcome the deficiencies in the prior art.
The utility model is achieved in that bavin oil and gas mixed combustion control system automobile oil door fuel limit device, comprise core processor unit, core processor unit is connected with signal output module, communication module, signal acquisition module and parameter setting module, signal acquisition module is connected with input signal standard interface; Signal output module and communication module are connected with standard connection interface.
Owing to have employed technique scheme, compared with prior art, the utility model just can be completed and former car Throttle Opening Control module and mixed connection of firing control system by simple plug, it normally runs auxiliary diesel rock gas mixed combustion control system for realizing, and controling effectively to vehicle accelerator signal provides hardware foundation.The utility model using process is simple operations, and installs simple, greatly reduces the pressure of field technician's maintenance work, and auxiliary derv fuel and natural gas double-fuel mixed combustion control system are normally run.When double fuel mixed combustion system cloud gray model, the utility model, by mixing the control overflow of combustion system according to control algorithm and double fuel, limits vehicle accelerator signal magnitude; When double fuel mixed combustion system stalls, the utility model will recover vehicle accelerator signal magnitude.The utility model structure is simple, and quick for installation, with low cost, using effect is good.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model: bavin oil and gas mixed combustion control system automobile oil door fuel limit device, comprise core processor unit 6, core processor unit 6 is connected with signal acquisition module 7, parameter setting module 8, signal output module 4, communication module 5, signal acquisition module 7 is connected with input signal standard connection mouth 9; Signal output module 4 and communication module 5 are connected with output signal standard interface 3.
In the present embodiment, core processor unit 6 can adopt the universal microprocessor (as flush bonding processor, single-chip microcomputer, DSP digital signal processor etc.) of being used widely, microprocessor should have outstanding calculated performance and the excellent system responses ability to event, can meet the demand to low dynamic and static state power in actual use simultaneously.
Output signal standard interface 3 comprises throttle signal output interface and communication standard connection mouth, and it can adopt standard signal interface (as automobile-used ECU standard signal interface, industrial signal connecting terminal etc.); Realize throttle signal output module 4 to be respectively connected fast with former car throttle acquisition module 1, communication module 5 fires control system 2 be connected fast with mixed.
Throttle signal output module 4 produces standard throttle differential output signal, when core processor unit 6 judges that running bar sets up, export the throttle signal after adjustment, when not possessing operating conditions, stop the throttle signal after exporting adjustment, recover the throttle signal of former car; Normally run for aid vehicle diesel gas mixed combustion control system.
Communication module 5 adopts standard universal communication chip (as RS485 chip, CAN chip etc.) and interlock circuit composition, carries out information exchange such as Operational Limits, system to report an error code etc. according to communications protocol and mixed control system 2 of firing.
Signal acquisition module 7 is made up of standard signal acquisition chip (as automobile-used level chip, technical grade chip etc.) and interlock circuit, by gathering the signal that gas pedal exports, be converted to digital signal, control the situation of throttle size variation for providing vehicle operator to core processor unit 6 by gas pedal.
Parameter setting module 8 is made up of on-off model input element, analog signals input element and interlock circuit, by simple operations, just can directly modify to the utility model Operational Limits, for the adjustment of the quick complete parameter of field technician.
Input signal standard interface 9 adopts the signaling interface of standard (as automobile-used level signaling interface, industrial level signaling interface etc.), and dust-proof, the problem such as waterproof, fool proof need be considered, being connected with former the quick of car accelerator pedal module 10 for completing, realizing the change that signal acquisition module 7 gathers throttle signal.
For convenience of execute-in-place, above-mentioned each parts, when connecting, can be extended by flexible row's cable as required.In the utility model, each parts those skilled in the art can require select voluntarily or design concrete product or circuit according to its application function.
The Placement of the said equipment is the known approaches of those skilled in the art, just repeats no more herein.
