Traditional aircraft magnetos, a WWII-era technology, are mechanical, have many moving parts prone to failure, and offer fixed settings and a weaker spark, leading to inefficient combustion.

IN many internal combustion engines the ignition of the explosive mixture is effected by means of an electric spark which is produced by a small machine called a magneto. The great demand for these ...

F. R. HAIGH has recently compared the relative advantages of magneto and coil ignition used for generating the explosions which occur in motor-car engines (Students' Quart. J. Inst. Elec. Eng., Dec.).

[Dan] wanted to learn a bit about solid state ignition in engines; to get started he needed a test subject, so he decided he would upgrade his old 12 horsepower lawnmower. Originally the lawnmower ...
