Operating Characteristics of a Spark-Ignition Engine Using the Second Law of Thermodynamics: Effects of Speed and Load 2000-01-0952
A thermodynamic cycle simulation was used to obtain the performance, energy and availability characteristics as functions of speed and load for an automotive spark-ignition engine. Availability is an important thermodynamic property related to the second law of thermodynamics. The manner in which the total original energy and availability are used, displaced or destroyed is exhibited. As an example of the results, the availability destroyed by the combustion process (as a percentage of the fuel availability) ranged between 20.3 and 21.4%. This fraction was lowest for the highest speeds and loads, since these conditions were best at preserving the fuel availability.
