This book reports on a novel approach for generating mechanical energy from different external
heat sources using the body of a typical piston engine with valves. By presenting simple yet
effective numerical models the authors show how this new approach which combines existing
internal combustion technology with a lubrication system is able to offer an economic solution
to the problem of mechanical energy generation in piston engines. Their results also show that
a stable heat generation process can be guaranteed outside of the engine. The book offers a
detailed report on physical and numerical models of 4-stroke and 2-stroke versions of the EHVE
together with different models of heat exchange valves and results of their simulations. It
also delivers the test results of an engine prototype run in laboratory conditions. By
presenting a novel theoretical framework and providing readers with extensive knowledge of both
the advantages and challenges of the method this book is expected to inspire academic
researchers advanced PhD students and professionals in their search for more effective
solutions to the problem of renewable energy generation.
