Abstract
A kind of starting, idling enrichment-system, by on automobile, installing clutch switch additional, clutch pedal switch, neutral switch, accelerator pedal switch, four switches are wired on the additional circuit respectively, additional circuit is wired to idling enriching solenoid valve, when the driver carries out driveaway operation, the signal that additional circuit transmits according to four switches learns that automobile is in starting, just to idling enriching solenoid valve, allow idling bypass air flue aperture strengthen, reduce motor and the wearing and tearing of clutch when vehicle starting, reduce the generation of dead fire, make vehicle starting more fast, and the driver need not be by hand braking when uphill starting, but the same pacifically operation like a cork.
Description
Affiliated technical field
The utility model relates to a kind of rich idling setting, especially a kind of rich idling setting relevant with starting.
Background technique
At present, rich idling setting on the automobile is for the ease of engine start and prevents that motor rotating speed under idling operation from crossing lowly or unstable that reduce dead fire and take place, the idling enriching divides the enriching when starting is arranged again, the enriching in air condition compressor when work, the automobile electrical enriching when excessive of loading.But the rich idling setting of enriching when not having at present specially for starting, especially automobile is when uphill starting during like this owing to vehicle starting, and engine load is big, and engine speed was low excessively when automobile was in semi-linkage, abrasion is big and easily dead fiery, and getting on the car on the slope then has down the danger of slipping.
Summary of the invention
Can not improve engine speed in order to overcome existing auto idle speed system when the vehicle starting, this the utility model provides a kind of starting, idling enrichment-system, the dead fire and the wearing and tearing of motor when reducing vehicle starting, and the driver need not be by hand braking when uphill starting, but the same pacifically operation like a cork.
The technological scheme that its technical problem that solves the utility model adopts is: the utility model is by installing clutch switch additional on automobile, clutch pedal switch, neutral switch, accelerator pedal switch, four switches are wired on the additional circuit respectively, additional circuit is wired on the electronic fuel injection engine electronic control unit, when the driver carries out driveaway operation, additional circuit transmits earth signal according to four switches learns that automobile is in starting, just the electronic fuel injection engine electronic control unit is given in the number of delivering a letter, can be by revising the program in the engine electronic control unit, make electronic control unit obtain just allowing idling bypass air flue aperture strengthen behind the signal, for preventing that engine air from burning, if long-time motor does not also load, idling speed is too high, then turns down idling bypass air flue.Idling enriching solenoid valve is housed on the car car that has, as adopt the car of the car of Carburetor or some dress electronic fuel injection engine, their air-conditioning system is equipped with idling enriching solenoid valve in addition, additional circuit also can be without the electronic fuel injection engine electronic control unit, but directly to idling enriching solenoid valve, thereby make the idling enriching.
Clutch switch adopts displacement switch, and when the driver stepped on clutch, displacement switch had positive displacement, and makes vehicle starting when the driver gently lifts clutch, and after negative displacement had appearred in displacement switch, additional circuit worked, and engine idle improves.If but the driver's operation clutch is for gear shift, then the driver can push neutral gear to speed-changing lever from certain gear, neutral switch will be given the trailing edge of a voltage of single-chip microcomputer transmission of additional circuit through being switched to disconnection, thereby to know automobile be not then inoperative in starting to circuit; When additional circuit worked in the starting-up process, driver's right crus of diaphragm had moved on on the gas pedal and the pedal of stepping on the throttle carries out refueling operation, and accelerator pedal switch disconnects, and additional circuit stops to work.Clutch pedal switch is the main switch that a push switch is done additional circuit, as long as clutch pedal is being stepped on, switch is powered to additional circuit with regard to conducting.
The beneficial effects of the utility model are: reduce motor and the wearing and tearing of clutch when vehicle starting, reduce the generation of dead fire, make vehicle starting more fast.
