摘要： A rapidly heated glow plug which concentrates its heat at the tip of the protective sheath of the plug so that the tip is the first part to heat to the ignition temperature. The plug is heated by a coil of positive temperature coefficient resistance material such as nickel, and the method of manufacturing the plug results in there being a mass of PTC material at the tip of the protective sheath, with the coil being connected to this mass. The preferred mass is formed by melting several coils of wire within a hole formed in the tip of the sheath to close the hole and expose a large surface area of positive temperature coefficient resistance material at the very tip of the sheath to be heated first.
