Book about striking engine design

Post by sham.MY »

Are there any book that i can refer to that have a complete description about Stirling engine?
I really needed some reference for me to construct an Alpha Stirling engine.

You can start with a free down load of Andy Ross's book "Making Stirling Engines", no plans as such.

Yes, i have download and read the book. However, they just give the specification of the model. The calculation are not stated.
That why i need a good source of revision specifically to find the right formula to build Andy Ross Ross D-60 Stirling engine.
Hope you guys will help me?

About the only "formula" you need is the 1 : 1 ratio between the hot and cold cylinders, the rest is just good engineering.

currently i trying to determine the crank angle X for my design of Stirling engine D-60 that used inverted yoke as it crank mechanism.
What is the crank angle X that required for the expansion and compression piston to be at TDC and BDC?
Hope you guys could help me a bit how to determine the crank angle?

The crank angle is automatically set by the yoke, it's not 90*, but seems to work ok, I did see the angles somewhere, but can't remember. Ian S C

Does this image can help me to find the crank angle when the Expansion piston is at TDC and so on?

The above diagram is more than I had to build my motor. Ian S C

I have James G. Rizzo's book "The Stirling Engine Manual vol 1", I would also like to get vol 2 which is a bit more advanced. These books are well worth reading, they have plans for a number of engines, and useful hints.

I have the same book,. Just arrived today.
It is one of the best books I have read in a long time and am excited about the crank system.

Here is my interpretation of a Ross Yoke motor. Ian S C

Ian wrote on another post:
"All of my BETA and GAMMA motors are set at 90*,the ALPHA motor is a Ross Yoke type, and the angle is somewhat different, 120* I think I saw written somewhere."

One thing for the original post, I believe the angle of the cylinders isn't what matters but the degrees of delay of TDC of the 2 pistons in an alpha design. In the drawing posted above, the pistons themselves wobble, which doesn't seem like a good idea to me.

my 2 cents...

Where does one find a reasonably priced version of Rizzo's book? "The Stirling Engine Manual vol 1"
$90 from amazon is too steep...



In this write up, the Siemens double-acting wobble plate alpha engine (United Stirling) is impressive:
