Abstract

Provided is a spark plug for a methanol fuel engine. A common spark plug is directly applied to a methanol fuel engine, so that the engine is difficult to ignite normally and work normally. Therefore,the spark plug with high temperature resistance, corrosion resistance and higher ignition energy is required to be applied to a methanol fuel engine. The composition of the spark plug comprises a shell (6) with threads (5). The shell is provided with a sealing base (4), the right end surface of the sealing base is a conical surface, the right end of the shell is provided with an insulator, the insulator is provided with a central electrode (7), the end part of the metal shell is welded with a conical side electrode (8), and the gap between the conical side electrode and the central electrodeis 1mm. The plug is used for the methanol fuel engine.

Description

Technical field: [0001] The invention relates to a spark plug, in particular to a spark plug for a methanol fuel engine. Background technique: [0002] With the progress of society and the development of science, engine technology is also changing with each passing day. Due to the country's emphasis on environmental protection, vehicle exhaust emissions have become a source of pollution that cannot be ignored. Emission regulations are becoming increasingly stringent, which poses challenges to the emission control of traditional fuel engines, and the cost of manufacturing fuel engines that comply with environmental regulations has also increased. With the encouragement of national policies, more and more methanol fuels have been applied to the market, and thus, methanol fuel engines have also entered the market. [0003] Most of the current engines are ordinary fuel engines, including gasoline or diesel. Compared with methanol fuel, methanol fuel has certain corrosiveness a...
