Fig. 13. Ericssons Hot Air Engine after it is compressed by the piston, is explodedusually by a hot tube, or an electric spark, whichproduces what is called the power stroke. The beginning of the gas engine dates back to1678 when the Abbe dHautefeuille, of France,conceived the idea of using the explosive powerof gunpowder on a piston to make it do work. 22 The Boys Book of Engine-Building Philip Lebon, also of France, patented an enginein which he proposed to use coal gas as the ex-plosive fuel. The first gas engine that actually worked wasinvented by Lenoir, likewise of France, in i860.He used gas for the fuel and this was exploded

Fig. 14. Ottos Gas Engine by an electric spark, but since the gas was ex-ploded without being compressed, his engine wasvery wasteful and inefficient. To Dr. Otto, of Germany, belongs the creditof having brought the gas engine to a successfulconclusion in 1878. This was done by drawing The First Engines 23 in the gas on the suction stroke, compressing iton the compression stroke, exploding it to pro-duce the power stroke and exhausting the burntgases on the exhaust stroke. Hence this kind ofa gas engine is known as the Otto four cycleengine and to its development is due not only theautomobile, but that mightier marvel, the air-plane.
