Designing for silence

Post by Wellington »

Can anyone offer up any tips on designing a free piston stirling engine with linear alternator to run as quietly as possible? I'm wondering which parts of the engine will make the most noise. I was also wondering what can be done to increase torque in a free piston engine.

Torque is the turning motion of a crankshaft, I'm not sure what you call the force of the piston in a straight line as in a free piston motor. As long as you design the motor so that there is no collision between the displacer, and power piston and the end of the hot cap there should be virtually no noise.
To increase power, increase the heat input, and up grade the cooling system, up the pressure.
