Advantages 2 strokes thermocompression
Dipl.-Ing. Christian Daublebsky von Eichhain Engine Expo 2013 Open Technology Forum
Thermo Compression Engine
Low pressures
Less mechanical stiffness (e.g. cheap ball bearings possibles)
High efficiency
Excellent for cogeneration
Low Noise
Disadvantages 2 strokes thermocompression
Dipl.-Ing. Christian Daublebsky von Eichhain Engine Expo 2013 Open Technology Forum
Thermo Compression Engine
Heat exchanger needed
Limit on max. revolution / min due limits for heat exchanger (max. ca. 3000 rev/min)
Lower power per volume
