Abstract

An energy-saving environment-friendly spark plug is composed of a central electrode, an inclined-face housing, a sealing washer, a porcelain tube insulator and a wiring screw. The energy-saving environment-friendly spark plug is characterized in that the central electrode is a leaf-shaped multi-pole central electrode; the end face of the central electrode is of a circular arc shape; there are 3 to 8 leaves of the central electrode; and the inclined-face housing forms a slope from a thread root A with a diameter of 11.9mm to the housing end part B with a diameter of 10mm to reduce the face contacting the multi-pole central electrode, alleviate and even eliminate carbon deposit phenomena. The self-cleaning capabilities of the spark plug are thus improved. Mixed gas inside a combustion chamber can be fully combusted. Tail exhaust gas emission can be reduced. Fuel can be saved by 10% to 15%. Harmful gas polluting the air, such as CO and HC can be reduced. Furthermore, the service lifetime of the spark plug can be prolonged by more than one time.

Description

A kind of energy-saving environmental protection spark plug

Technical field:

The utility model belongs to a kind of gasoline engine part technical field, specifically a kind of energy-saving environmental protection spark plug that is applicable to automobile and motorcycle gasoline engine use.

Background technology:

Domestic and international existing automobile, the central electrode of the petrolic spark plug of motorcycle is the single-point lateral electrode, this spark plug comprises spark-plug body, wiring screw rod, the central electrode of seal washer and spark plug termination and single-point lateral electrode form, the arcing gap of the spark plug that the central electrode of this spark plug and lateral electrode form, under the effect of high-tension electricity, ionization occurs rapidly in central electrode and the air between lateral electrode of spark plug, form ion and the electronegative free electron of positively charged, when interelectrode voltage reaches certain value, the ion of gas and number of electrons surge, making air is to lose insulating effect, the gap just forms discharge channel, punch-through occurs, and namely occurs " spark ".The temperature of this electric spark up to 2000 °～3000 ℃, be enough to light the indoor mist of cylinder combustion, the shortcoming of this spark plug is: because the single-point discharge spark between central electrode and lateral electrode just exists to be difficult for starting and to produce circuit fire phenomenon under the cold climate condition, because mist can not be fully burned, the waste part of fuel, the discharge capacity of tail gas waste gas is large, causes air pollution, and easy carbon deposit between two electrodes, the shortcomings such as self-purification capacity is low, and useful life is short.

Summary of the invention:

Problem to be solved in the utility model provides a kind of energy-saving environmental protection spark plug, it has that engine easily starts, not cutoff, carbon deposit, self-purification capacity are not strong, make mist sufficient combustion, fuel saving, reduce the tail gas discharge amount of exhaust gas, alleviate the advantages such as air pollution and long service life.

Problem of the present utility model is to solve like this:

(1) central electrode of this spark plug is the multipole electrode of foliaceous, and this central electrode is that end face is circular-arc;

(2) housing directly as lateral electrode, the inclined-plane housing is that Φ 11.9mm is that Φ 10mm becomes a gradient to shell end B from thread root A, its end thickness is 0.5 to 0.8mm, with the contact-making surface of minimizing with multipole central electrode, thereby reduce so that removing carbon, improve the self-purification capacity of spark plug, because multipole shape central electrode forms the spark plug sparking gap toward the gap of external radiation and iron-clad end, under the effect of high-tension electricity, can be radiated iron-clad gap on every side by multipole shape central electrode at every turn multi spot spark occurs, mist is fully burnt, improve engine power, reduce the tail gas discharge amount of exhaust gas, thereby reach energy-conservation and reduce air pollution.

The utility model compared with the prior art its advantage is:

1, can multiple spot sparking, ignition power by force, not cutoff, start soon, cold and hot car is rapidly starting all, is particularly useful for cold district;

2, measure its rate of economizing gasoline through national spark plug product quality supervision inspection center and reach 10% to 15%;

3, because multiple spot is struck sparks, this spark plug self-cleaning properties is good, not carbon deposit, can not produce circuit fire phenomenon, mist is fully burnt, and the discharge capacity of pernicious gas CO, HC etc. reduces by 50% than state specified standards in the tail gas, and prolong one times or more than existing spark plug its useful life;

4, the engine power moment of torsion all is significantly improved in whole condition range, and is particularly more obvious in the economical raising of moderate speed range;

5, use the utility model, needn't do any change to engine, needn't increase any annex, as long as adjust ignition distributor, make ignition angle suitable, adjust carburetor and suitably reduce fuel delivery, its reduction is as the criterion not reduce engine power.

Embodiment:

This energy-saving environmental protection spark plug comprises the multipole central electrode 1 of foliaceous, inclined-plane housing 2, seal washer 3, porcelain tube insulator 4, wiring screw rod 5, the blade that it is characterized in that this central electrode is 3 to 8, embodiment is 6, the end face of this central electrode 1 is circular-arc, inclined-plane housing 2 is that Φ 11.9mm is that Φ 10mm becomes a gradient to shell end B from thread root A, its end thickness is 0.5～0.8mm, with the contact-making surface of minimizing with multipole central electrode, reduce so that the removing carbon phenomenon, improve the self-purification capacity of spark plug, increase the service life, and the mist of combustion chamber is fully burned, thereby realize to reduce the tail gas discharge amount of exhaust gas, fuel saving and alleviating air pollution.
