Abstract
Nowadays the global warming is more and more being severe. Such a situation enables us to utilize soft energy resources more rather than hard energy ones. As the matter of course the engine presented here uses charcoal as its fuel. Less leakage of working gas and easy handling were prior to others in designing the machine. Prior to its performance tests theoretical estimation for engine output were carried out by using Schmidt theory, which informs us that the machine will achieve the predetermined performance. In addition, we can see here general structure of the engine together with its specifications.
