SOLO engine is quite interesting.
output performance can be adjusted by the working gas pressure
40 and 130 bar in the range of 3 to 9 kW
the 3.25 fold pressure increase generating a 3 fold power
is diminishing returns. For each extra bar of pressure a lesser
gain in power is achieved.
first bar increment achieves the biggest power increase.
suggestion is that, for our boating needs, we should have a few
bar, use helium and
have two cylinders. The cylinder swept volume is then another
option to “marry”
vs size, effort and complexity.
sufficiency of variety.
BUT!............. Make, MEASURE and modify.
The swept volume is 160 cc
