The utility model with the advantages of simple structure and convenient configuration efficiently solves the problem that engines of vehicles are difficult to start under low temperature.

Description

Automobile-used low temperature gasification starter

The utility model relates to automobile-used low temperature gasification starter, is a kind of device that overcomes motor car engine cold-starting difficulty.

At cold area, under the cryogenic conditions, can not get atomization and vaporization after the low temperature gasoline of confession engine start and the ice-cold Metal Contact, can not form the gas that the supply engine starting is burnt in suction tude to cylinder, is the basic reason that causes the occurs at low temperatures motivation not started.

The purpose of this utility model is at the existing vehicle problem of starting difficulty at low temperatures, and provide a kind of simple in structure, configuration is convenient, the fuel oil that enters motor is heated rapidly, be rapidly evaporated to inflammable gas and make motor smooth automobile-used low temperature gasification starter of starting under cryogenic conditions.

The technological scheme that realizes the utility model purpose is: a kind of automobile-used low temperature gasification starter, comprise fuel tank for automobile through the oil pipe serial connection, the motor petrol pump, Carburetor and be arranged on engine air inlet tube below the Carburetor, be provided with a holding flange body at Carburetor and engine air inlet tube connecting part, suspend the heating and gasifying dish of an in-built electrical heated filament peripheral hardware thermistor in midair in the engine charge tube chamber through this body flange, the heating and gasifying dish is provided with a three-way pipe, three outlets of its three-way pipe are respectively on the heating and gasifying dish, following card, the entrance point of its three-way pipe is connected on the oil inlet pipe of fuel tank and motor petrol pump behind oil pipe serial connection electronic fuel pump and gasoline filter.

The utility model compared with prior art has following advantage:

1, simple in structure, need not make structural change during with existing vehicle configuration, easy for installation.

2, this starter is to utilize gas with engine start, has overcome the Carburetor car, has directly sprayed that car relies at low temperatures to the many oil spouts of cylinder and can not the perfect combustion problem of environment pollution caused after starting.

3, existing Carburetor car, directly to spray that car starts at low temperatures be to advance cylinder with liquid gasoline, washes out the oil film between piston and casing wall easily, quickens machine members.This starter advances cylinder with gas, has reduced machine members.

4, to pilot engine at low temperatures be to enter cylinder with liquid oil plant for existing vehicle, swashs wet spark plug easily, causes arcing to weaken.This starter advances cylinder with gas, can not swash wet spark plug, helps gas to be lighted.

5, existing vehicle does not advance cylinder because of multiple reason causes gasoline at low temperatures, causes starting difficulty.This starter forms inflammable gas in suction tude, can charge into each cylinder voluntarily under the effect of gas itself, has overcome the oil that is caused by multiple reason and has not advanced the problem of Cylinder engine fail to start.

6, this starter utilizes gaseous combustion to pilot engine, and has solved existing atomizing starter and has been met by the atomizing in when beginning and be reduced into that liquid oil plant advances cylinder after cold again and swash wet spark plug and quicken the problem of component wear.

7, when different faults appears in oil circuits such as running into Carburetor, this starter itself also can be with engine start.Can play the Carburetor car in starting cold moment, directly spray the not available effect of cold nozzle of car.

8, because mixed gas that will be burned is heated, evaporated earlier, generate the gas supply cylinder in suction tude, not only reduce fuel delivery, save fuel oil, and help gasoline and fully burn, and then the reduction exhaust is to the pollution of environment to cylinder.

Accompanying drawing is this low temperature gasification starter structural representation.

The utility model is described in further detail below in conjunction with drawings and Examples:

Provide as accompanying drawing, the utility model comprises the fuel tank for automobile 1 through the oil pipe serial connection, motor petrol pump

2, Carburetor 3 and be arranged on engine air inlet tube 9 below the Carburetor, be equipped with a holding flange body 6 in Carburetor 3 and engine air inlet tube 9 connecting parts, suspending the heating and gasifying dish 8 of an in-built electrical heated filament peripheral hardware thermistor in midair in engine air inlet tube 9 chambeies through suspension rod below this body flange, in the specific implementation, can add netted surrounding edge in the upper and lower card of gasification dish, to improve the gasification efficiency of heating and gasifying dish.Be fixed with a three-way pipe 7 on the heating and gasifying dish, three outlets of this three-way pipe 7 are the horse shoe shaped mouth of pipe, spout part respectively near and towards the upper and lower card of heating and gasifying dish.Provide as accompanying drawing, in the present embodiment three of three-way pipe outlets wherein two be arranged on the upper disk surface place that adds the gasification dish, another one is arranged on the following card place of its gasification dish.The entrance point of three-way pipe 7 is connected to the oil outlet of electronic fuel pump 5 again by fine flexible pipe by body flange by the capillary metal, the filler opening of electronic fuel pump 5 connects the oil outlet of gasoline filter 4, and the filler opening of gasoline filter is connected on the oil inlet pipe of fuel tank 1 and motor petrol pump 2.

Below in conjunction with accompanying drawing the working principle of this starter being done one describes:

When connecting ignition switch, starter relay is connected the circuit of the electric heating wire in the heating and gasifying dish 8, the electrothermal wire heating is heated up the gasification dish rapidly, when the gasification dish reaches more than 70 ℃ temperature, the thermistor Yin Gaowen that is attached to below the gasification dish reduces resistance rapidly, and signal is passed to temp controller, and temp controller is connected the circuit of electronic fuel pump 5, electronic fuel pump begins to spray into fine oil bundle simultaneously to upper and lower two cards of heating and gasifying dish 8, and makes it flash to inflammable gas rapidly.Because gasification dish and thermistor are descended rapidly by the sharp back temperature of penetrating of cold oil simultaneously, the resistance of thermistor can sharply increase, and has cut off the path of temp controller and electronic fuel pump 5 thus at once, and electronic fuel pump stops to heating and gasifying dish 8 fuel feeding.At this moment, the one, temporarily stop the gasification dish that gasoline continues input low temperature, avoid liquid gasoline to enter suction tude, the 2nd, to time of heating up again of gasification dish, the 3rd, the gasoline of last input is fully evaporated.When the gasification dish lose swashed by low temperature gas and oil spray after, temperature again can very fast rise, the temperature that makes thermistor increases again and resistance reduces, temp controller makes electronic fuel pump 5 coil 8 oil spouts to gasification again again.Heating and gasifying dish, thermistor, electronic fuel pump three constantly repeat said process with this, promptly are that this starter constantly provides the process of inflammable gas in suction tude, cylinder, thereby satisfy the smooth starting of motor under cryogenic conditions.
