Simplicity...............Number of parts reduced 80%
Vibrationless...............Rotary motion instead of reciprocating
Exhaust gases cool, clean...............Excess air flows through engine, fuel completely nontoxic burned, practically no carbon monoxide
Overload won't "kill" the engine...............Compressor and first-stage turbine rotate independently of power turbine --keep on idling even if sudden overload stops power turbine
Light, compact...............Few parts
Dependable low-temperature starting...............Low friction--fuel injected directly into combustion chamber--igniter fires repeatedly- -timing not important- -vaporization not critical
No warm-up period needed...............Can operate under full power if desired as soon as fuel is burning steadily
Instant heat available in winter...............Hot gases immediately available as soon as engine is operating under own power--no cylinder block and coolant to heat up first
Negligible oil consumption...............No pistons or cylinder walls to lubricate
Antifreeze not required...............Temperature controlled by air flowing through engine--therefore no water, no antifreeze
Operates on wide variety of fuels...............Less limited by vaporization or detonation characteristics of fuel
Less maintenance...............No tune-ups required--less friction and wear- -fewer parts- -no valves, camshaft, distributor, etc.
