Description

Automobile electrical autocontrol petrol economizer

The utility model relates to a kind of automobile circuit petrol economizer, particularly a kind ofly can realize the automatically controlled petrol economizer.

At present, in existing car engine machine circuit, generally all be by an ignition lock directly the power connection of storage battery in driving engine, realize power supply.To carburetor engine, ignition system runs an engine; Simultaneously, make the action of carburettor idling electromagnetic valve, open the oil pipe passage, to engine oil.Perhaps to fuel injection systems (ECU) driving engine, supply terminals fire-fighting oil.And to diesel motor, flameout switch is switched on and is opened, the energising of electromagnetism oil cut-off valve, and oil circuit is connected fuel feeding.In a word, in case ignition lock is connected engine starting, with regard to a direct power supply, fuel feeding.No matter automobile travels, stop, upward slope, downhill running, all in ceaselessly oil consumption power consumption, causes the unnecessary waste of oil plant.

Some petrol economizer is reequiped on oil circuit, increases annexes such as some joints, conduit, oilhole, needle-valve; Also some petrol economizer is with the break-make of computerized control system control oil channel; When automobile downhill, disconnect oil circuit, make not fuel feeding of driving engine, realize the fuel-economizing purpose.But the petrol economizer manufacture difficulty is big, complexity is installed, and cost is very high.Also additive incrementation some driver behavior programs.

The purpose of this invention is to provide a kind of automobile circuit automatic guidance petrol economizer, its assembling is simple, and easy for installation, with low cost, the fuel saving ratio height is easy to again promote in various vehicles.

The purpose of this utility model realizes in the following manner: at first, that the supply line of engine igniting system and fuel-feed system is separately independent from general automobile circuit.The petrol economizer that serial connection is made of one group of ON-OFF control circuit between ignition lock and engine igniting system and fuel-feed system supply line, ON-OFF control circuit by three micro-switchs and a coolant-temperature switch mutually and connect, micro-switch is put switch gearing with Das Gaspedal, pedal of clutch and Transmission gear respectively, coolant-temperature switch is installed in the engine-cooling system, change with operating temperature, thereby realization is to the Comprehensive Control of motor circuit power supply fuel feeding.Slowing down or descending advances when sliding, particularly during the upland highway downhill running, the outage oil-break, the racing of the engine operation reaches the purpose of fuel-economizing.

Advantage of the present utility model is that principle is simple, is convenient to assembling, need not make key technological transformation to original automobile, installs easily, and is with low cost, all kinds of automobiles such as Petrol carburetter car, and EFI car (ECU), or diesel-powered vehicle is all applicable.The utility model petrol economizer, contactor are installed in carries out interlock on the former steering unit, do not increase new action, does not influence driver's operation.For further specifying the technical solution of the utility model, be described in detail below in conjunction with drawings and Examples.

Fig. 1 is a control circuit schematic diagram of the present utility model

Fig. 2 is embodiment of the present utility model.

Referring to Fig. 1, automotive battery power lead (1) terminates to ignition lock (2) end, by ignition lock K ₀(3) end is series-connected to control group (4) end, and control group is respectively by K ₁, K ₂, K ₃, K ₄Often open micro-switch and coolant-temperature switch and connect composition for three.K ₁Be installed on the automobile accelerator pedal support, depress and the closure that links with Das Gaspedal; K ₂Be installed on the clutch-pedal bracket, be in off-state in the power-transfer clutch play motion, stepping on clutch is K switch in effective travel ₂Closed; K ₃Be mounted in the P PARK Position P switch on the transmission housing, be disconnection when advancing gear, neutral gear and reverse gear position are then closed; K ₄Then be a temp control switch that is installed in the engine-cooling system, closure during normal temperature, engine operating temperature just often disconnects.Control group mouth (5) is received gasoline car carburettor idling electromagnetic valve and ignition system mains terminals (6); Perhaps electro jet car (ECU) ignition system is controlled power lead input end (7); Perhaps the engine electromagnet oil cut-off valve power lead of diesel-powered vehicle and flameout switch mains terminals (8).Therefore form an automatic control circuit, realize the Comprehensive Control of motor circuit and fuel feeding.

In conjunction with Fig. 2 embodiment, the K in the switches set ₁, K ₂, K ₃, K ₄-end is bonding respectively, and the other end also is linked as the control coil that (9) end is connected to relay L, and L is controlled.The main contact of L is an open contact, and (10) end is connected in series with ignition lock K ₀Mouth (3), the other end is as the mouth (11) of control group.Receive (6) or (7) or (8) end equally, respectively.

When the automobile cold start, ignition lock K ₀Closure, because of engine temperature is a normal temperature, K ₄The coolant-temperature switch closure, L relay coil energising, main contact (10) end is logical with (11) termination, will be from the electric current of battery feed through ignition lock K ₀The supply engine normal ignition starts, and connects oil circuit, fuel feeding.

Behind automobile starting, during the running of neutral idle operating mode, K ₃The micro-switch closure, after engine temperature raises, K ₄Coolant-temperature switch disconnects, and still can keep normal working of engine.

When automobile normal running, the conversion gear is stepped on power-transfer clutch K ₂Closure, conversion D Drive K ₃Disconnect release the clutch pedal K ₂Disconnect again, depress throttle K ₁Closed.In the whole operation process, remain and have at least a switch to be alternately closed, automatic guidance is connected the L coil, makes the L main contact connect power supply, fuel feeding.Ensure automobile normal running.

When automobile is in deceleration or downhill running, unclamp throttle, K ₁Disconnect; Stepping on clutch not, K ₂Also disconnect; Because of automobile is positioned at D Drive, K ₃Also be in off-state; This moment, engine operating temperature was normal, K ₄Temperature control disconnects already; Relay coil is not switched on, and the supply line that ignition lock leads to engine igniting system and fuel-feed system has been cut off in L relay main contact tripping.To the gasoline car carburetor engine, the high-tension coil outage misfires, and the idling electromagnetic valve has disconnected oil circuit; To the gasoline electric injection driving engine, ignition system is not worked, and outage also causes not oil spout; And to diesel motor, outage makes flameout switch be in closed condition, and the electromagnetism oil cut-off valve has been blocked oil circuit again.In a word, this moment, driving engine was in a kind of outage, oil-break state, reached the purpose of saving fuel oil.Simultaneously, anti-pass is moved owing to downhill running, and free-runing operation also can produce braking favourable drag effect, and control rate ensures safety.

During parking, unclamp Das Gaspedal K ₁Disconnect driving engine outage, oil-break; Braking deceleration, stepping on clutch pedal, K ₂Connect, move back neutral gear K ₃Connect again, brake left alone without help car, and driving engine enters normal idling mode.
