Summary:The “Steam Super Stirling Engine (SSSE)” is a hybrid
engine of Rankine cycle steam engine and steam Stirling engine. This
engine has a power piston and a displaced piston. When the power piston
comes near its top dead center, saturated steam of 0.2-1.0 Mpa is
injected into the cold side of the displaced cylinder, and the steam
expands into power cylinder at constant high temperature after passing
through a regenerator and heater, as a Stirling engine. Many small
remodeled atmospheric engines were tasted. Then a small double expanding
SSSE was installed on an electric vehicle for the generation of
electricity. Each engine above was successful, and the following points
known: (1) power increases to several times those of atmospheric
Stirling engines; (2) this engine needs no Helium gas; (3) nearly no
cooling system and pressurized crankcase are needed; and (4) theoretical
thermal efficiency is expected to be in the middle of both cycles
