Another long thread spark plugs, the more and more applications, such as Elysee (16 V), Changan Ford's carnival, Shanghai Volkswagen's Passat 2.0 L, POLO cars, and Shenyang 4 G69 Mitsubishi engine, and so on are used in long thread spark plugs .
Development Trend

Because of the surge in world oil prices, petrol was growing CNG (natural gas), and LPG (liquefied petroleum gas) to replace, especially in North China, natural gas is rich in resources, many of the original diesel engine manufacturers will be converted into a gas engine, will replace gasoline engine oil Dual-engine, now many domestic as Beijing, Chongqing, Chengdu and other big cities in the oil and gas taxi use two vehicles, buses, the use of natural gas. Natural gas combustion engine is characterized by slow, atmospheric pressure, high ignition voltage, thermal load, the fuel combustion mechanism and there is a change, which calls for the spark plugs, power lines, ignition coil structure has changed, in view of the characteristics of Gas Engine , Xianghuoju companies spark plugs, power lines, the overall design of the ignition coil, dual-use gas for spark plugs, oil and gas and power lines supporting the use of this power can reduce the conduction losses, the output waveform stability, improved engine performance started to purify the cylinder to reduce carbon deposition, extend engine life, the system stability.
