Description
Technical field
The utility model relates to a kind of engine ignitor, and especially a kind of high pressure that do not produce can not lighted liquid fuel, and in light weight, volume is little, showing tremendous enthusiasm the ignition mechanism that petrol engine simple in structure is used.
Background technique
At present, known volume production petrol engine all uses spark plug to light a fire, in each cycle period, by the igniting of spark plug electrion once, with sustainability and the stability of guaranteeing engine operation.Whole ignition system is by spark plug, high pressure packet, and igniter, power supply etc. are partly formed, though this technology is very ripe, the structure more complicated, system's number of fitting parts is many, and weight ratio is bigger, and electromagnetic interference is arranged to external world, need do shielding processing.
As the patent No. is 02260153.8 1 kinds of ignition device of gasoline engine, it is characterized in that between spark coil and distributor, being provided with an eliminator, its advantage is: because the existence of low-pass filter circuit is arranged, the high-frequency harmonic that produces during gasoline engine ignition is able to filtering, avoided the interference of the radiation of frequency electromagnetic waves, improved electrical spark intensity radio installation.
And for example the patent No. is 200620010761.6 the showing tremendous enthusiasm formula engine ignitor of a kind of model plane.This device is made up of power supply, power circuit; power supply connects the power input of power circuit; showing tremendous enthusiasm head is connected on its output terminal; by switch power module and be connected on the power circuit that the resistor of its output terminal constitutes; this ignition mechanism automatic locking circuit of when input supply voltage is lower than threshold voltage, cutting off the electricity supply; thereby the safety of protection ignition mechanism and power supply adopts methyl alcohol to act as a fuel at model airplane engine, rather than gasoline.
And for example the patent No. is a kind of energy-saving gasoline engine ignitor of 97233578.1, belongs to spark ignition, is used for the igniting of gasoline car, and the patent No. is a kind of plug ignition device of 02254403.8, all belongs to the plug ignition device.
Summary of the invention
The purpose of this utility model is all to use spark plug to light a fire in order to solve existing petrol engine, more complicated, the problem that system's number of fitting parts is many provides a kind of high pressure, safety of not producing, can not light liquid fuel, can not produce the electromagnetic radiation that causes owing to high pressure yet, and in light weight, and volume is little, showing tremendous enthusiasm ignition mechanism simple in structure, that a kind of petrol engine that reliability is high is used.
The technological scheme that its technical problem that solves the utility model adopts is: showing tremendous enthusiasm the ignition mechanism that petrol engine is used, comprise positive electrode, negative electrode (being shell), seal ring, electric heating wire, ceramics insulator, electric heating wire is connected between the both positive and negative polarity, this is the heat accumulation part, be responsible for lighting mixed gas, the positive electrode the other end is provided with notch, system links to each other with externally fed, negative electrode is axially arranged with through hole, through hole is separated into large through-hole and small through hole at the middle part, the internal diameter of large through-hole and the external diameter of ceramics insulator are suitable, the external diameter of the external diameter of small through hole and the external diameter of positive electrode and electric heating wire is suitable, electric heating wire within the housing of negative electrode, with the endoporus of negative electrode be that small through hole has certain space, a some contact is only arranged, ceramics insulator is arranged between positive electrode and the negative electrode, the length of ceramics insulator and large through-hole length are suitable, and the length of electric heating wire and the length of small through hole are suitable, and this device is an integral type after making.
As preferably, be provided with seal ring and screw thread between described negative electrode and the cylinder block, for easy installation and removal, after assembling, good fixing effect, adopt thread connecting mode, seal ring adopts metallic material, as copper, because during engine operation, heat is very big, and is not yielding with metal washer, and the upper dimension of negative electrode and the installing space of cylinder block are suitable, on cylinder block, be provided with and showing tremendous enthusiasm the installing space that ignition mechanism is suitable, negative electrode and cylinder installing space also keep certain space, can play heat radiation.
As preferably, described electric heating wire contacts with the firing chamber, and during igniting, the spark that electric heating wire produces finally will contact with gasoline, and the firing chamber is being lived coldly during away from showing tremendous enthusiasm, as the volume of cylinder, and when living cold close showing tremendous enthusiasm the time, is burning cavity.
As preferably, after described device and cylinder block were installed, its entire length did not exceed the installing space of cylinder block, from the positive electrode of cylinder block end after assembling, its head had both made in the production installation process in the cylinder block installing space, was difficult for making showing tremendous enthusiasm ignition mechanism to be collided.
The utility model is compared with the igniting of spark plug formula, and following advantage is arranged: do not produce high pressure, and safe, can not light liquid fuel, can not produce the electromagnetic radiation that causes owing to high pressure, in light weight, volume is little, and is simple in structure.
