Excerpt from Diesel's Rational Heat Motor: A Lecture

Based on these actual facts, a new motor of 20 horse-power was built, which in the beginning of 1897 was tested with petroleum, and upon which the following data are presented: The engine is shown by Figs. 4 to 7. From this can be seen that the cylinder, for the reasons previously explained, is provided with a cooling jacket; that the plunger with oil stuffing boxes is replaced by a ring-piston; that the gear shaft has been extended to the top; that suction and exhaust valves are separated, etc. The small air pump Q. Driven by connecting rod Z and lever X, keeps the vessel L filled with compressed air under a higher pressure than the highest compression attained in the cylinder, and is a new detail. By means of the pipe connection S. The same excess of pressure is connected with the interior of the injection valve D. In it the petroleum is collected during the intervals in the four cycle period between the combustion periods. This petroleum is introduced by a little pump. Not shown in the figure. By Opening the valve stem 11, the fuel is by its high pressure caused to flow through the nozzle opening D to the combustion chamber of the engine. Thus creating the combustion period in accordance with diagram 1. Wherein the form and length of the combustion line can be altered according to the performance of work, partly by chang ing the regulation of the fuel supply, partly by changing the excess of pressure in the vessel L and finally by performing the injection at different points on the compression line, as previously demon strated.

Excerpt from Diesel's Rational Heat Motor: A Lecture

Our German contemporary, the Zeitschrift des Vereines Deutscher Ingenieure, contains a lecture delivered by Rudolph Diesel at the general meeting of the society at Cassell, held June 16, 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 Age 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 9 per cent. from smaller double expansion engines down to 150 to 200 horse-power; 5 per 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 and Schroter. In practice, however, this theoretical cycle can be executed only approximately. Therefore, we call n the total or economical efficiency.
