Introduction
Each of the link pages listed below, contain an example image of the Manufacturer's or Brand's Spark Ignition Engines, and if found, provides some detail, such as engine name, size, approximate year of production, country of origin, designer, maker and manufacturing company location.
The first true "Spark Ignition" petrol engine was made in 1884, by the British engineer Edward Butler, who also invented the spark plug, the ignition magneto, coil ignition and the spray jet carburettor.
Miniature Spark Ignition engines, for small scale models, commonly referred to as "Sparkie" engines, were developed in the early years of the 20th century, and in general, still use a coil ignition system based on that designed by the American inventor Charles F Kettering in 1911.
There are a wide range of Fuel mixtures used for model Spark Ignition engines, dependent on type of model the engine is for (Car, Airplane, Boat etc), and mixtures for competition use are fiercely guarded secrets, but generally are simple mixtures of around 3 to 1, gasoline and oil.
