Abstract
The utility model relates to a new style spark plug with a precombustion chamber. The utility model is characterized in that a cylindrical precombustion chamber which surrounds two electrodes in the cylindrical precombustion chamber is formed on the extending part of a hell, and a small hole is arranged on the cylindrical precombustion chamber. The electrical spark firstly ignites the gas in the precombustion chamber, and the mixing gas in the cylinder block is ignited by making use of the flame which is ejected from the precombustion chamber and is generated form the precombustion chamber. The utility model has thorough combustion, no carbon deposition, little pollution, and fuel saving.
Description
The utility model relates to petrolic spark plug.
Normally used spark plug has different seating heights of plug insulator according to different engine working conditions, thereby the branch of " cold mould " and " pattern of fever " is arranged, and different thermal value range is arranged.The branch that projected nose type spark plug and retraction type spark plug are arranged again according to the relative position of skirt section and housing.No matter that a kind of form is electric spark and directly lights combustion gas in the cylinder.This common spark plug, often at used car, or when engine turned round under low speed, running on the lower load, spark plug may be because of the serious stained cutoff of carbon deposit.And, often have fuel gas to have little time fully to burn and be discharged from owing to directly light combustion gas by spark, cause polluting and waste.
A kind of flame ignition formula engine (1962 9 phases of automobile monthly magazine) is arranged, a precombustion chamber is arranged between spark plug and cylinder block, behind the precombustion-chamber ignition, the rich mixture flame of high temperature, the lean mixture in the main combustion chamber is lighted in ejection consumingly from the precombustion chamber spray orifice.This device need provide the gaseous mixture of two kinds of variable concentrations respectively, and a cover pre-chamber arrangement and a fueller need be set.
The purpose of this utility model is that a kind of improved spark plug will be provided, and this is a kind of spark plug that precombustion chamber is arranged in the end, lights gaseous mixture by the flame that precombustion chamber produces.
Spark plug such as Fig. 1 that the utility model is prepared to provide are characterized in the housing of common spark plug is prolonged, and form a precombustion chamber (generally being cylindric)＜6 〉, and this precombustion chamber is with two electrodes surrounding portion within it.＜1〉is wiring screw rod among the figure,＜2〉center sieve bar and electrode,＜3〉be ceramics insulator,＜4〉be housing,＜5〉be the lateral electrode that links to each other with housing, the end of precombustion chamber is frustum shaped＜7 〉, has a spray orifice＜8〉in the middle of truncated cone end, is distributed with several subsidy apertures＜9〉on the cone on every side of hole＜8 〉.
This spark plug that has precombustion chamber is work like this: when mist in the cylinder compresses to a certain degree, spark plug is by the mist in the two interelectrode spark ignition precombustion chambers, the gas that has burnt rapid swollen length in precombustion chamber expands, and at full speed in precombustion chamber, spray, the gas band that has fired flame and rapidly the mist in the main combustion chamber is almost lighted simultaneously, Here it is the said flame ignition gaseous mixture in front, rather than common spark ignition.Flame ignition is compared with spark ignition, and have obvious advantage: it is big to light face, the burning rate height, and diffusion is fast, therefore can burn fully, can reduce because of incomplete combustion produces pollution, can improve power and reduce fuel consumption.Use the spark plug of flame ignition, reliable operation start easilier, and no carbon deposit especially has tangible usefulness to the engine of sneaking into machine oil in use inferior fuel and the gaseous mixture.
Use the spark plug as Fig. 1, its pre-chamber cavity macropore is little, and flame sprays from the hole, the jet velocity height, it is big to light face, rapidly to the main combustion chamber diffusion, makes the interior mist of main combustion chamber almost light sufficient combustion simultaneously instantaneous, its simple structure is made easyly, and advantage is outstanding.
Another improvement of the present utility model is before above-mentioned spark plug is not produced as yet and popularized, can be at pedestal that has above-mentioned precombustion chamber of the bottom of common spark plug adjunction.Its embodiment is seen Fig. 2, and＜10〉are common spark plug among the figure, and＜11〉are precombustion chamber pedestal of the present utility model, and the internal thread on pedestal top and the rib-loop of spark plug join, and the pedestal bottom has external screw thread can be screwed in the screwed hole that spark plug is installed on the cylinder head.The end of pedestal is the truncated cone equally, and have one of spray orifice and via hole several.
On common spark plug, install the precombustion chamber pedestal additional, can promote present technique early, obtain economic benefit early.
Claims (2)
1, a kind of spark plug, by ceramics insulator, wiring screw rod, central electrode, have externally threaded housing, and the lateral electrode that links to each other with housing etc. partly form, it is characterized in that the extension of housing form one with two electrodes surrounding in interior cylindrical shape precombustion chamber, has the truncated cone body in cylindrical shape precombustion chamber end, have a hole in the middle of the truncated cone shape end of body, on the cone around this hole, be distributed with several apertures.
2, spark plug as claimed in claim 1, a pedestal that has precombustion chamber is characterized in that spinning at rib-loop place, wide-range spark plug bottom, its end has the truncated cone body, has a hole in the middle of the truncated cone shape end of body, is distributed with several apertures on the cone around this hole.
