Engines need three things to work: fuel, oxygen, and an ignition point. The glow plug provides that ignition by heating the element (which is the small coil of wire inside the plug). This is usually done with a 1.5v battery contained in a glow ignitor. Some of the more recent vehicles have on-board batteries that ignite the glow plugs as part of an electric starting system.

Engraving (also called line engraving) is a is an intaglio printmaking process -- or the print made from such a process -- in which a plate, usually copper or steel, upon which an artist draws his image directly into the plate by making lines in the metal with a tool called a burin or graver. Etching -- soft ground: is a variation on the hard ground method that allows the artist to create a more textured line. 2  In this method the harder ground is mixed with another substance such as axel grease, rolled onto the plate, which is then heated until the ground is tacky.
