Spark plugs are one of the most misunderstood components of an engine. Numerous questions have surfaced over the years, leaving many people confused. This guide was designed to assist the technician, hobbyist, or race mechanic in understanding, using, and troubleshooting spark plugs. The information contained in this guide applies to all types of internal combustion engines: two-stroke engines, rotary engines, high performance/racing engines and street vehicles. Spark plugs are the “window” into your engine (your only eyewitness to the combustion chamber), and can be used as a valuable diagnostic tool. Like a patient’s thermometer, the spark plug displays symptoms and conditions of the engine’s performance. The experienced tuner can analyze these symptoms to track down the root cause of many problems or to determine air/fuel ratios The spark plug has two primary functions: 1. To ignite the air/fuel mixture 2. To remove heat from the combustion chamber Spark plugs transmit electrical energy that turns fuel into working energy. A sufficient amount of voltage must be supplied by the ignition system to cause it to spark across the spark plug’s gap. This is called “Electrical Performance.” The temperature of the spark plug’s firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. This is called “Thermal Performance”, and is determined by the heat range selected. It is important to remember that spark plugs do not create heat, they can only remove heat. The spark plug works as a heat exchanger by pulling unwanted thermal energy away from the combustion chamber and transferring the heat to the engine’s cooling system. The heat range is defined as a plug’s ability to dissipate heat. The rate of heat transfer is determined by: 1. The insulator nose length 2. Gas volume around the insulator nose 3. The materials/construction of the centre electrode and porcelain insulator A spark plug’s heat range has no relationship to the actual voltage transferred through the spark plug. Rather, the heat range is…
