Introduced: September 1968

Title

Titles differ between systems:

IPC: the working fluid being generated in an internal-combustion gas generator of the positive-displacement type having essentially no mechanical power output

CPC: the working fluid being generated in an internal-combustion gas generated of the positive-displacement type having essentially no mechanical power output (internal-combustion engines with prolonged expansion using exhaust gas turbines F02B)
