Description

Electric heating evaporation formula automobile low temperature starter

The utility model is a kind of automobile low temperature starter.

In prior art, domestic automobile exists and is difficult to the problem of starting under the low temperature, this is because the Carburetor of domestic automobile is gasoline and the mixing naturally of air that will lean on it to spray could form the vaporized fuel supply engine to a great extent, so, under the temperature of cold, as subzero below 10 ℃, because air is too cold, the gasoline of its ejection can not mix with cool air, drops in the inlet manifold of motor but form oil droplet, makes motor can not get vaporized fuel and can't start.So not only wasted fuel, also easy damaged machinery.In order to address this problem, some low temperature starter is attempted to reach the effect that makes the normal vaporization of fuel with the way of air in the heating Carburetor, for example: add a netted electric heating apparatus between Carburetor and engine suction manifold.Though this structure can make the cold starting performance of motor obtain a bit improving, but can not tackle the problem at its root, this is because the heat exchange area of heater is too little, can only around heater, form little by little heat group, air in the Carburetor is still terribly cold, gasoline still can not normally be vaporized, and the oil droplet that falls also is the heat exchanger surface of moment by heater, also can not fully be vaporized, therefore, effect can not be satisfactory, and particularly at cold area, this low temperature starter does not almost have effect.

The purpose of this utility model is at the problem that heat exchange area is little, low-temperature startup performance is not good enough in the existing low temperature starter, and a kind of electric heating evaporation formula automobile low temperature starter is provided.

Task of the present utility model is finished like this: its design philosophy is to make its evaporation form vaporized fuel by the oil droplet that the heating Carburetor falls, and reaches the purpose of starting rapidly under the low temperature.Its concrete structure is: it is made up of with the heating timing controller that is installed in this electric evaporator on the bridge the droop electric evaporator that is installed between Carburetor and the engine suction manifold; Described droop electric evaporator is made up of with the suspending type electric heating evaporation dish that is located at this breaking-out type plate below a breaking-out type plate that can be installed between Carburetor and the engine suction manifold, described suspending type electric heating evaporation dish is by disk body and be fixed on the disk body center, also upwardly extending connecting rod is formed, and the upper end of described connecting rod is fixed on the breaking-out type plate by net formula or support frame type link.

By above-mentioned solution as can be seen, electric evaporator is made one and collected disk shape, and is sagging below Carburetor, in the inlet manifold of motor.During vehicle starting, control the heating of electric heating evaporation dish earlier by timing controller, and then start, when starting, in the Carburetor not the fuel of vaporization will be dropped on the electric heating evaporation dish, oil droplet is met heat and can be evaporated rapidly and form vaporized fuel and give motor, then automobile can start at once.Experiment shows that under-40 ℃ of cryogenic conditions, this starter can make motor car engine start smoothly, and the one push start success rate reaches 96%, and enters idle running very soon after the starting, is difficult for flame-out.Simultaneously, the utility model also has preheat time short (less than 1 minute), engine performance is not had influence, compact structure, reliable performance, advantage such as simple to operate, easy for installation.
