FERNANDEZ-ABALLI-ALTAMIRANO, Carlos; CALCOEN, Michael; VANDERMEERSCH, Edward  y  GONZALEZ-BAYON, Juan J.. Experimental Tailer like Thermal Lag Engine to obtain pressure and volume diagrams. Ingeniería Mecánica [online]. 2013, vol.16, n.1, pp. 35-40. ISSN 1815-5944.

The Thermal Lag Engine (TLE) patented by Peter Tailer's is briefly introduced. The discussion about the thermodynamic working principle of this external combustion machine is presented. For this work the claims in literature have been studied by the authors to design and develop an experimental installation with the objective of measuring for the first time the pressure-volume (pV) relationship of a TLE as described by Tailer and West. The pV diagrams are presented here and support previous theoretical claims about the TLE. Their triangular form shows the effects described by West in the expansion and compression processes caused by the variation of the cold heat transfer area. Also the relationship between the heat transfer capacity of the engine and its working frequency becomes apparent from the measurements, indicating that larger heater areas and limited cold heat transfer characteristics allow more work production per cycle at higher operating frequencies.

Palabras clave : thermal lag engine; pressure-volume diagrams; external combustion engines.
