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
