The engine is a multi-cylinder 4-stroke glow igniter, which was developed by myself. Except for the carburetors, no parts from other engines were used, each component is my own design.

The engine is air-cooled and operates with mixed lubrication (methanol and synthetic oil). It is designed as an aircraft engine, but is not based on any particular model.
