The Free Piston Engine is a combination of reciprocating engine and rotary turbine. It is called free piston engine because the freedom motion for Mechanical linkage which gives variable stroke according to load.

ADVANTAGES

1. Mechanical simplicity
2. Less power to weight ratio
3. Lower turbine operating tempeatures
4. Multi fuel capability
5. Flexibility and reliability
6. Easy starting and control
LIMITATIONS
1. Poor fuel economic
2. Less stability
3. Poor part load efficiency
4. High combustine rates
5. Reduction gearing

A patented new power machine concept has been designed and analyzed for production, and proof of principle subscale tests have been performed, with positive results. The machine design concept is applicable as a compressor, pump, motor, or engine. Simplicity of design based on spherical ball pistons enables a low moving part count, high power to weight ratio, elimination of valve train and water cooling systems, and perfect dynamic balance.The new design concept utilizes novel kinematic design to completely eliminate inertial loads that would c ....etc
