One end of body 2 is provided with outlet connector 11, and the other end is provided with inlet opening connector 10, and body 2 is provided with SC sigmal control output unit 3, sensor signal receiving element 4 and manual and automatic control unit 5;
Manual and automatic control unit 5 is connected with supervisory keyboard 6 by extending wire harness;
Connector 12 and the electronic control device for vehicle 1 of former car of described rat tail 13 one end match, connector 7 and the outlet connector 11 of the other end match, and match again with automobile wire harness connector 8 simultaneously;
When described body 2 accesses former car, that body 2 is connected between the electronic control device for vehicle 1 of former car and automobile wire harness connector 8, namely the connector 12 of described rat tail 13 one end is connected with electronic control device for vehicle 1, and the connector 7 of the other end is connected with described outlet connector 11; Described inlet opening connector 10 is connected with automobile wire harness connector 8;
When described body 2 does not access former car, the connector 12 of described rat tail 13 one end is connected with described electronic control device for vehicle 1, and the connector 7 of the other end is connected with automobile wire harness connector 8.Such as: user thinks body 2 of temporarily dismantling, and the position of the electronic control device for vehicle 1 of some car is very hidden, be not easy to dismounting, utilize this root rat tail 13 directly to allow rat tail to connect described electronic control device for vehicle 1 and automobile wire harness connector 8.
The inside of described body 2 is provided with direct circuit, driver can start or stop described auxiliary electronic control oil-saving device of automobile, that is: can control body 2 makes connector 7 lead directly to automobile wire harness connector 8, and without the need to pulling out body 2, this considers from the angle of safety, and body 2 is once go wrong and will switch to pass-through state.
Described SC sigmal control output unit 3 controls oil nozzle and the lambda sensor of former car, for adjusting air fuel ratio, namely increasing or reducing air fuel ratio;
Described sensor signal receiving element 4 receives former car sensor signal, and described signal comprises load signal, front oxygen sensor signal, post oxygen sensor signal, oil nozzle signal, throttle signal, air flow meter signal or manifold pressure signal;
Described manually and automatic control unit 5 have two kinds of control modes, be respectively automatic control mode and MANUAL CONTROL mode, automatically proceed to automatic control mode when not connection control keyboard 6;
Under automatic control mode, SC sigmal control output unit 3 regulates according to the chemically correct fuel of setting, and the parameter of different automobile types setting is also not quite similar; Oil-saving effect is in such a mode relatively less better, and can not realize dynamic mode.
Under MANUAL CONTROL mode, user selects automobilism pattern by supervisory keyboard 6, the automobilism pattern that user selectes by manual and automatic control unit 5 gives SC sigmal control output unit 3, SC sigmal control output unit 3 is according to automobilism pattern analysis air fuel ratio, then be optimized adjustment according to the chemically correct fuel of setting, reach good travelling state;

Described manually and automatic control unit 5 be connected with display screen 9 by extending wire harness, for showing various parameter, the per 100 km average fuel consumption mainly comprising fuel injection pulsewidth and calculate according to fuel injection pulsewidth, object is former car and enables the contrast of this device.
SC sigmal control output unit 3, sensor signal receiving element 4 and manually and automatic control unit 5 can independent operating or out of service.
SC sigmal control output unit 3 independently can control fuel injection signal by SCM program by electronic circuit, its objective is suitable adjustment, increases or reduces air fuel ratio, and it is carry out in the scope of allowing that the control of this unit exports; The automobile sensor signal data received, is carried out storing in order to calling by electronic circuit by single-chip microcomputer by sensor signal receiving element 4; Manual and automatic control unit 5 is, by single-chip microcomputer, instruction is sent to SC sigmal control output unit 3, data when sending instruction in first query sensors signal receiving unit 4 are carried out as calculated afterwards, if SC sigmal control output unit 3 does not receive manually and the instruction of automatic control unit 5 time, the program according to setting is run.
The sensor signal of the every a car of same label different model and the every a car of different label different model is also not quite similar, and need mate different auxiliary electronic control oil-saving device of automobiles according to actual conditions.
Car industry bound pair gasoline engine has a chemically correct fuel that is 14.7: 1, the optimizing regulation of indication of the present invention is divided into closed loop control, opened loop control two kinds of optimizing regulation, so-called closed loop control is relative opened loop control, namely feedback is had between controlled device and control gear, the result exported can return control gear to adjust, and closed loop is a real-time lambda sensor, triangle relation closed between computer and amount of fuel control gear three.Lambda sensor tells the air fuel ratio situation of computer mixed gas, and computer is given an order to amount of fuel control gear, and to the direction adjustment air fuel ratio of theoretical value (14.7: 1), this adjustment often can exceed some theoretical values.Lambda sensor is discovered out, and reports computer, and computer is given an order and adjusted back to 14.7: 1.Because the circulation of each adjustment is very fast, so air fuel ratio can not depart from 14.7: 1 forever.Once run, this closed loop adjustment just successively.In addition, also some conditions to be met: 1. lambda sensor must reach operating temperature (about 315 DEG C).2. engine water temperature must reach critical temperature (about 65 DEG C).3. after engine start, through predetermined time (from several seconds to one or two minutes).Such as: be exactly closed loop control when the normal speed per hour of motor travels.
When air fuel ratio is unaccommodated, with opened loop control, during as warming-up process or WOT.Under this control mode, the sensor information that computer uses has water temperature, load, barometric pressure and engine speed.These information determines air fuel ratio, once these information processings are complete, computer sends suitable order to mixture control assembly.Except non-input changes, otherwise this order does not change.In this mode of operation, computer does not use the input information of lambda sensor, so do not know the sent operating conditions that whether can obtain anticipation about air fuel ratio order yet.Due to this weakness of open loop, Computer application proceeds to closed loop system as early as possible, and stays operation with closed ring pattern as far as possible.Such as: automobile is exactly opened loop control when firm startup idling.
Here optimizing regulation is a complicated computer processing procedure, analyze judgement according to the signal of automobile sensor, its main purpose reduces fuel consume under guarantee meets the normally loaded prerequisite of automobile, such as: the auxiliary electronic control oil-saving device of automobile through test drops to 2.1ms at the fuel injection pulsewidth of auto idle speed from 2.9ms, motor normal operation.
The invention solves the excess drive force that exists in prior art or be short of power, high oil consumption, the problem such as maximum discharge, can be widely used in using vapour, diesel oil as the various internal-combustion engines of fuel.
Technique scheme is one embodiment of the present invention, for those skilled in the art, on the basis that the invention discloses application process and principle, be easy to make various types of improvement or distortion, and the method be not limited only to described by the above-mentioned embodiment of the present invention, therefore previously described mode is just preferred, and does not have restrictive meaning.
