Munich, 2 Oktober 2013 – 100 years ago we lost an engineer who left a legacy of truly moving. Without his motor with a current efficiency close to 50 percent, we have “peak oil” may have long behind us. His enthusiasm for science, a thorough training for engineer, his sharp mind and an unwavering perseverance made him develop a motor that would make ideal Carnot’s theory of thermodynamics apply.
As is often the case with such projects failed and diesel in the absolute – but then, as an engineer – to develop an implementation of the practical achievable. This fact was, however, who then tragically would keep him busy the rest of his life with patent litigation. When, after more than 15 years working his “heat engine” worked, although he had done an engineering feat, but not managed to really represent the ideal Carnot cycle. However, that was the theoretical basis of his earlier filed patent.Failed on Absolute
Diesel began looking for a rational source of power well when he found out how bad the efficiency of the then most widely used heat engine. Stationary steam engines were then still at about 10 percent, in locomotives and ships was achieved through better utilization of the expansion work, thanks to variable valve timing and use of residual heat sometimes up to 15 More time was not there, and even as the last stationary steam engines and locomotives were delivered new in the mid-1960s in Germany, they were only slightly higher. That it could not be, Diesel had already learned many decades ago as a student at the Technical University in Munich, because the thermodynamic theory of the steam engine, the scientists had of course long time already completely under control. It was purely practical reasons for which they have held in certain areas so long
