The complete set of plan drawings for the exciting Stirling-Steele Engine is available from the inventor and designer himself.( The package contains 26 pages of highly detailed drawings and instructions providing all the necessary information to produce this modern compact version of a Stirling Engine. The Stirling Steele Engine can be machined on a 6" lathe and small milling machine from readily available material. A full Bill of Materials (BOM) is included as are assembly instructions. This is not a kit but a full set of dimensioned drawings.

In the Stirling-Steele engine, four gamma type Stirlings are daisy chained together. This is done by driving the displacers via linear drive rods which are attached to the top of power pistons. The rods pass thru a sealed bulkhead and the displacer cylinders are ported to power piston cylinders that are phased behind them 90 degrees. This allows an engine that only requires one crank throw per piston where other types of Stirlings require two. Fewer crankcase penetrations along with a simpler crank permit for a more cost effective engine to manufacture. Building four cylinder engines instead of single cylinder units has several strong advantages such as easy starting, good balance, smooth running even at very low speeds, increased heater and cooler surface area and good low end torque. As an external combustion engine, the Stirling-Steele engine can easily meet the EPA standards for carbon monoxide and hydrocarbon emissions. Since it is a closed cycle device, it runs very quietly without the need of a muffler.

The New Steele Double-Cam Stirling Engine. The new double cam drive is a very versatile and cost effective answer to multi cylinder beta type Stirlings. Beta type Stirlings with their higher compression ratios have long be thought to be the most hopeful Stirling for integrating into our energy hungry world. Now with this new Stirling drive it is possible to group or cluster multiple beta type Stirlings together to provide compact cost effective Stirling power producing engines or heat pumps for real world applications. Plans for this engine and finished engines based on this design are not available for sale however the US Patent covering this design improvement is available for license..
