【正文】 he micro— horsepower world of model Stirling engines it takes only a small amount of friction to have a huge impact on performance． I learned pressure leaks will rob you of precious power． A tiny pressure leak will help a Stirling engine equalizeto match the changing barometric pressure， or help it bleed off a little excess pressure as the average temperature rises in the engine． But with that advantage es a loss of power． My little engine needed all the power it could muster， especially for the lower temperature differentials I wanted it to run on． Some miniscule pressure leaks seemed impossible to avoid， such as where a moving shaft must pass through the wall of the pressure chamber． I eventually found a way to use mags to replace that pushrod so now my pressure chamber is pletely sealed． I learned that balance is a difficult science． A typical design has a rotating flywheel that lifts the displacer up and down． You add a little weight to one side of the flywheel in order to pensate for the weight of the displacer． You place the weight opposite of the load so that when the displacer is moving up， the counterbalance is moving down． This makes the displacer motion almost effortless． I have used this technique to successfully reduce vibration and wobble， but I have never been able to pletely eliminate it． I needed to create a design that did not require the flywheel to lift anything． If it wasn’ t lifting anything， balance would not be a problem． So now the challenge is to apply these lessons to the building of an LTD engine． Lower temperature differential means this engine will have less power than the pop can engine． This means it will have to have more precision， less friction， and a straightforward application of the Stirling cycle． And I have to do this without the aid of a machine shop! 外文翻譯中文： 往復(fù)式發(fā)動機 我對于互聯(lián)網(wǎng)的研究，最終導(dǎo)致我進入了美國斯特 林公司。 Precision is re
