ES30922U - Spark plugs for explosion engines (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Insulating parts of the two electrodes of the spark plugs of the explosion engines, characterized in that the said insulating parts are manufactured with the porcelains known as "soapstone" and whose commercial names are diverse, among them the ultraesteatite, clino- Steatite, Calit, Faradex and Frecuentite, which have special qualities regarding their composition, their electrical and mechanical conditions and their thermal behavior, which communicate to the aforementioned insulating parts the advantages that have been exposed, which can be summarized in the following: ) less probable breaks, even with very revolutionized or high compression ratio engines; b) possibility to operate the motor with low battery or lower voltage coils; c) elimination of electrical losses due to the absorption of grease and the need to varnish the porcelain; d) possibility to reduce the number of spark plug types needed to cover the entire range of engines from the coldest to the hottest; all of which essentially modifies the qualities of the insulating parts described in the necessary sense according to section 3 of Article 48 of the current Statute of Industrial Property, referring to the change of subject matter patented as possible content of the patent.
