Abstract
The utility model discloses a low-temperature staring electronic spark plug which is composed of the following components: a ceramic insulator, and a metal housing which coats the lower part of the ceramic insulator. The top end and the bottom end of the ceramic insulator are respectively provided with a wiring nut and a central electrode. A grounding electrode is welded at the bottom end of the metal housing and is right below the central electrode. The low-temperature staring electronic spark plug is characterized in that: one end of a heating resistance wire which is placed outside the bottom end of the metal housing and/or in the ceramic insulator is fixed on the metal housing, and the other end is connected with one end of a heating resistance wire conductor equipped on the metal housing; and the other end of the heating resistance wire conductor is successively connected with a heating button switch, a fuse and an anode of an automobile battery. The low-temperature staring electronic spark plug has the following advantages: capability of instantaneously heating temperature of an engine of a methanol automobile to a normal temperature of the engine, instantaneously igniting methanol and starting the methanol automobile at a low temperature; no pollution; energy saving and emission reduction; engine protection; and prolonged service life of the engine.
Description
Technical field
The utility model relates to motor vehicle equipment, especially relates to a kind of cold-starting electronics spark plug.
Background technology
Traditional spark plug can only play the effect into car engine ignition.Because the flash-point of methyl alcohol is than the flash-point height of gasoline, therefore, methanol vehicle is when low temperature, because the temperature in the cylinder is low excessively, spark plug is difficult to the engine point is caught fire, and the driver will ceaselessly, again and again light a fire and just might beat, and just is difficult to start below temperature 12 degree.The energy consumption of engine will be far above the energy consumption of engine in normal temperature, and exhaust emission is also higher relatively.And engine weares and teares also excessive when low temperature, can shorten the useful life of engine.
Summary of the invention
The purpose of this utility model provide a kind of the engine temperature transient heating of methanol vehicle to normal temperature, instantaneous ignition methyl alcohol, allow methanol vehicle low temperature just can normal starting, pollution-free, protection engine, remove spark plug fouling, prolong the engine electronics spark plug in useful life.
A kind of cold-starting electronics spark plug, formed by ceramics insulator and the metal shell that is wrapped in the ceramics insulator bottom, top and bottom at ceramics insulator are separately installed with wiring nut and central electrode, central electrode conductor with wiring nut and central electrode connection is installed in ceramics insulator, the wiring nut connects the high-tension bus-bar of coming from distributor cap, outer wall at metal shell is processed with the external screw thread that spark plug is screwed into cylinder, bottom at metal shell, be welded with grounding electrode under the central electrode, the spark plug gap that the 0.6-1.0 millimeter is arranged between central electrode and the grounding electrode, high-tension electricity will burst out the spark ignition gaseous mixture through this spark plug gap with going into, feature is: an end of resistive heater is fixed on the metal shell, the other end of resistive heater is connected with an end of the resistive heater lead that is installed in metal shell, the other end of resistive heater lead successively with the heat button switch, the positive pole of fuse series connection automobile storage battery.
Resistive heater is placed on the outside, bottom of metal shell; Or resistive heater is composed in series by two sections, one section outside, bottom that is placed on metal shell, and another section is fixed on the bottom in the ceramics insulator.
The heat button switch is installed in the next door of the ignition switch of steering yoke.The utility model is to have set up resistive heater and heat button switch on the basis of conventional ignition plug; like this; as long as the driver presses heat button switch three seconds and just can rise to the temperature of engine air in-cylinder combustion rapidly more than 12 degree when cold-starting; at this moment just can normally start methanol vehicle immediately at low temperatures; and need not again and again light a fire, play the protection engine, prolonged the engine effect in useful life.Therefore, the utlity model has the engine temperature transient heating of methanol vehicle to engine normal temperature, instantaneous ignition methyl alcohol, allow methanol vehicle just can start at low temperature, pollution-free, energy-conservation joint row, protect engine, the prolongation engine advantage in useful life.
