Definition
The term "hot air engine" specifically excludes any engine performing a thermodynamic cycle such as the Rankine cycle, in which the working fluid undergoes a phase transition. Also excluded are conventional internal combustion engines in which heat is added to the working fluid by combustion of fuel within the working cylinder. Continuous combustion types such as George Brayton's Ready Motor and the related gas turbine could be seen as borderline cases.

Famous quotes containing the word definition:
“I’m beginning to think that the proper definition of “Man” is “an animal that writes letters.””

“It is very hard to give a just definition of love. The most we can say of it is this: that in the soul, it is a desire to rule; in the spirit, it is a sympathy; and in the body, it is but a hidden and subtle desire to possess—after many mysteries—what one loves.”
—François, Duc De La Rochefoucauld (1613–1680)
