Production
Hot bulb engines were built by a large number of manufacturers, usually in modest series.These engines were slow running (300-400 RPM) and mostly with cast iron parts including pistons. The fuel pump was usually made with a brass housing and steel plunger operating with a variable stroke length. This resulted in a simple, rugged heavy engine. Therefore they could be machined in an average machine shop without special tools.
The Pythagoras Engine Factory in Norrtälje in Sweden is kept as a museum (the Pythagoras Mechanical Workshop Museum), and has a functioning production line and extensive factory archives.
