Why do you need to start this Stirling engine by hand?

Click For Summary
SUMMARY

The Stirling engine requires manual initiation due to insufficient initial power to overcome inertia. External work, such as pushing the engine by hand, is necessary to start the engine. Once operational, the momentum of the flywheel sustains the engine through its four phases, with power generation occurring in only one phase. This principle is similar to conventional engines that utilize starter motors for ignition.

PREREQUISITES
  • Understanding of Stirling engine mechanics
  • Familiarity with the four phases of the Stirling cycle
  • Knowledge of inertia and momentum concepts

The Attempt at a Solution


there is not sufficient power at first to overcome the inertia, so external work in the form of pushing it by hand is needed. however once started the momentum of the flywheel keeps the engine running?

Welcome to PF, mh1985! :smile:

Just like a regular engine, the Stirling process consists of 4 phases.
In only 1 phase does the engine actually generate power.
The flywheel keeps the engine running through the other phases.
(That's also why a regular engine needs a starter motor.)

I suspect that if you bring the flywheel in the right position, the engine should be able to start itself when heated.
 
Thanks for the response, and the warm welcome!
