The essential achievements of the work are
(a) downsizing factor (DSF) was defined first time in this
article (nobody before), (b) because of possibility of
exceeding thermal load in piston (as an example engine
part) the changes of DSF has to be restricted to almost 0.95
giving changes of 0.85 for base cylinder diameter and 0.90
ratio of base volume for stroke, (c) the main goal of
downsizing to reduce CO2 emission was results of all tests
but it show only 10% benefit, and (d) it is possible to
optimise the downsizing technology
