Glow plugs are used to help overcome this issue by introducing additional heat energy into the combustion chambers. [1] A glowplug resembles a short metal pencil. The heating element is fitted into its tip. Glowplug filaments must be made of certain materials, such as platinum and iridium, that resist oxidation and withstand high temperature ...
SplitFire was a company that manufactured a spark plug featuring a split ground electrode. SplitFire claimed that its "V" electrode design improved combustion by allowing the ignited flame to pass through the gap in the electrode, instead of around it.
Spark plug with single side electrode An electric spark on the spark plug. A spark plug (sometimes, in British English, a sparking plug, [1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within ...
Spark testing of tool steel Spark testing of mild steel. Spark testing is a method of determining the general classification of ferrous materials. It normally entails taking a piece of metal, usually scrap, and applying it to a grinding wheel in order to observe the sparks emitted. [1]
The "mudholes," or washout plugs, allow access to the interior of the boiler for washing and scraping away boiler mud and scale. The sheets on the left and right are called "side sheets" while the sheet in the front of the firebox is the flue sheet. The "front flue sheet" is in the front of the boiler and at the rear of the smokebox.

A fusible plug operates as a safety valve when dangerous temperatures, rather than dangerous pressures, are reached in a closed vessel. In steam boilers the fusible plug is screwed into the crown sheet (the top plate) of the firebox, typically extending about 1 in (25 mm) into the water space above it. Its purpose is to act as a last-resort ...
A modern ferrocerium firesteel product is composed of an alloy of rare-earth metals called mischmetal, containing approximately 20.8% iron, 41.8% cerium, about 4.4% each of praseodymium, neodymium, and magnesium, plus 24.2% lanthanum. [5] A variety of other components are added to modify the spark and processing characteristics. [2]
