Présentation de l'éditeur

Hi Libfary -I DIESELS RATIONAL HEAT MOTOR. Our German contemporary, the Zeitschrift desV ereines Deutscher I ngenieurey contains a lecture delivered by Rudolph Diesel at the general meeting of the society at Cassell, held June i6. 1897. As we are convinced of the great interest American engineers are taking in the scientific advancement and practical development of the gas-engine, we deemed it advisable to furnish the readers of Progressive A ge with an exact translation of said article, including reproduction of cuts and accompanying tables. After some introductory remarks, Mr. Diesel continues as follows: In regard to the high state of development of the steam-engine of to-day, it is a generally known fact that in the best triple expansion steam-engines of over 1,000 horse-power, from 12 to 13 per cent, only of the whole heat contained in the fuel is converted into actual work; only 9per cent, from smaller double expansion engines down to 150 to 200 horse-power; 5per cent, from small engines down to 50 horse-power, provided condensation is used, and far less from the smaller steam-engines and those without condensation. We all know the steam-engine to be one of the most perfect instruments of modern industry, brought to that height by our most able men having shown their best of talents in its development. In view of this fact, the figures given are exceedingly low, nearly incomprehensible, and although this is generally known, we should be reminded of it as often as possible, referring to such work, for example, as the researches of Zeuner andS chroter. First of all, the moving power, steam, receives but a fraction nof the caloric value Hof the fuel; Uj is the efficiency of the boiler, usually 75 per cent., occasionally 80, but never more than that. Furthermore, according to theoretical results, only a portion nof the whole heat UiH contained in the steam
