History
Staged combustion dates back to the hot bulb engine of the 1890s. The first stage of combustion occurred inside the hot bulb and the hot gases were then forced out into the cylinder, where they mixed with additional air, and the second stage of combustion took place. At this time, staged combustion was used because it was a convenient method of ignition and it is unlikely that there would have been much concern about air pollution.

Famous quotes containing the word history:
“If man is reduced to being nothing but a character in history, he has no other choice but to subside into the sound and fury of a completely irrational history or to endow history with the form of human reason.”
—Albert Camus (1913–1960)
“A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.”
—Aristotle (384–323 B.C.)
“Like their personal lives, women’s history is fragmented, interrupted; a shadow history of human beings whose existence has been shaped by the efforts and the demands of others.”
—Elizabeth Janeway (b. 1913)
