Number of cylinder:
JADE is available with a bore of either 10mm or 12mm, depending on the power you require.
- 10mm bore = suitable for 4-blade-propellors with diameter from 50mm – 65mm
- 12mm bore = suitable for 4-blade-propellors with diameter from 60mm – 75mm
- The JADE is delivered as finished, ready to run, engine.
The design of the JADE engine bases on suggestion from customers who wished for a robust and powerful but also compact and good-looking engine.
A further point was that the engine should also be simple to use and regulate. We have achieved this by employing piston-valves with optimised steam-channels combined with an enclosed reversing steam-valve for a sensitive regulation of speed and power. JADE requires only one servo for the full control of speed and reversing.
We also aimed In this design for a increased robustness and strength to allow for a higher max. working pressure to increase the power output. This, and the external aesthetics, makes this engine particularly suited for use in working ships like tugs or cargo-vessel. The increased use of visible steel emphasis the special character of this engine.
Excentres, cross-heads and columns are made from steel, piston- and valve-rods from stainless-steel, screws and bolts are either made from steel or stainless-steel. All other parts are machined from brass.
With the all-steel crank-shaft running in 5 solid brass bearing-blocks, the generously dimensioned bearing surfaces of the cross-heads, con-rods big- and small-ends and of the excentre-rings the JADE can be run with a working pressure of up to 4 bar (60psi)!
This compact engine is remarkably powerful!
