Gasoline motor spark plug with radiation fins and cranked electrode

Abstract

The invention discloses a gasoline motor spark plug with radiation fins and a cranked electrode. The radiation fins are made from conventional steel by maintaining a part of the steel which is originally cut. At least one, or two, or three or a plurality of radiation fins are arranged. The hexagonal shape of the radiation fin endows the radiation fin with the advantages that: 1, the radiation fin is convenient to machine together with a hexagonal spanner nut on the radiation fin by one cutter; and 2, the radiation fin is convenient for the deeper sleeving of a sleeve spanner in mounting. As an improvement, the gasoline motor spark plug particularly improves an ordinary single flat electrode into the cranked electrode (16), wherein the cranked electrode (16) consists of an extended part (16a), an arched part (16b) and a cranked part (16c) which are an equal distance away from a discharge electrode so as to form a discharge gap between a charged electrode and the discharge electrode; and the discharge gap is longer than a conventional line, which is favorable for increasing the absolute number of mixed gases in the gap and increasing the ignition probability.

Description

technical field [0001] The invention relates to an ignition device in combustion equipment, in particular to a spark plug for a gasoline engine with cooling fins and curved electrodes, and belongs to the technical field of spark plugs for ignition-type internal combustion engines. Background technique [0002] Ignition devices used in combustion equipment, especially gasoline engine spark plugs, are widely used to introduce pulsed high-voltage current into the combustion chamber, so that the mixed gas sucked into the cylinder can be sparked and ignited, and then diffused and burned to perform work. Between the external coupler of existing spark plug and the spark cap that has rubber shell, there is the phenomenon of being loose sometimes. Although the inside of the existing spark plug is provided with a glass sealant as a resistor, it only has impedance; if an inductive reactance and a capacitive reactance are added to form a suitable RCL circuit, it will have a more ideal e...
