From the day machines with reciprocating piston has come into existence efforts have been undertaken to improve the efficiency of the machines .The main drawbacks of reciprocating machines are the considerably large number of moving parts due to the presence of valves , greater inertial loads which reduces dynamic balance and leakage and friction due to the presence of piston rings . The invention urges has reached on Rotary machines .

One main advantage to be gained with a rotary machine is reduction of inertial loads and better dynamic balance. The Wankel rotary engine has been the most successful example to date , but sealing problems contributed to its decline . There , came the ideas of ball piston machines . In the compressor and pump arena, reduction of reciprocating mass in positive displacement machines has always been an objective, and has been achieved most effectively by lobe, gear, sliding vane, liquid ring, and screw compressors and pumps , but at the cost of hardware complexity or higher losses. Lobe, gear, and screw machines have relatively complex rotating element shapes and friction losses. Sliding vane machines have sealing and friction issues . Liquid ring compressors have fluid turbulence losses.

The new design concept of the Ball Piston Engine uses a different approach that has many advantages, including low part count and simplicity of design , very low friction , low heat loss, high power to weight ratio , perfect dynamic balance , and cycle thermodynamic tailoring capability

Efforts to develop rotary internal combustion engines have been undertaken in
the past, and are continuing.reduction of inertial loads and better dynamic balance is the main advantage of the rotary kind of engines. A very much successful model was the The Wankel rotary engine but the disadvantage of the sealing problems led to the decline of the engine.
The ball piston engine
The ball pistons rolling on an eccentric track is the basis of the design concept. tangential force is exerted by the balls on the cylinder walls which in turn turns the rotor. the rotor output shaft gives out the useful power. The spinning rotor itself contains the combustion chamber. The intake, compression, power, and exhaust strokes requires chamber porting and it is done by allowing the passage of the chamber tops across an internal stator.

Design Features
Many design features of the engine make it ideal for supporting high efficiency and emissions control. The porting that is required for the four stroke engine operation is done in a way which involves no valve train losses or additional moving parts.
