Refering to figure 1 [Fig.1], an oscillating « flipper » piston (1) and its associated chamber (2) are maintained without reciprocal contact. No oil is required because there no contact so friction. An shaft (22) maintains the »piston (1). Around (22), a twisting seal (8) allows for absolute sealing. This characteristic important Stirling engines oil-free compressors. Referring 4 [Fig.4], two p...
The free-piston Stirling engine is a closed-cycle regenerative heat that converts energy into mechanical work, and requires spring element for vibratory operations of the displacer power pistons. In this study, geometry flexural design was optimized through structural finite analyses fatigue test evaluations. First, we constructed target space considering required natural frequency assembly und...
An experimental investigation and optimization study of various piston geometries was conducted on Greaves single cylinder direct injection compression ignition engine using straight diesel and blends of rice bran biodiesel. The three combustion chamber geometries used in this study were Standard toroidal piston (STP), hemispherical bowl piston (HBP) and Shallow toroidal re-entrant piston (STRP...
