How they work Gallery Articles

"A hot air engine is any heat engine which uses the expansion and contraction of air under the influence of a temperature change to convert thermal energy into mechanical work. In a typical implementation, air is repeatedly heated and cooled in a cylinder and the resulting expansion and contraction is used to move a piston and produce useful mechanical work."

The engine shown here is a 90 degree Vee twin configuration with cast iron pistons running directly in an aluminium cylinder block / crankcase.
