In 1861 he also put one of his engines in a boat.[5] In 1863 Lenoir demonstrated a second three-wheeled carriage, the Hippomobile, little more than a wagon body set atop a tricycle platform.[2] It was powered by a 2543 cc (155 in3; 180×100 mm, 7.1×3.9in)[1] 1.5 hp "liquid hydrocarbon" (petroleum) engine with a primitive carburettor which was patented in 1886.[7] It successfully covered the 11 km (7 mi) from Paris to Joinville-le-Pont and back in about ninety minutes each way, an average speed less than that of a walking man (though doubtless there were breakdowns).[1] This succeeded in attracting the attention of tsar Alexander II, and one was sent to Russia, where it vanished. Lenoir himself was not pleased, however; in 1863, he sold his patents to Compagnie parisienne de gaz and turned to motorboats, instead, building a naptha (Ligroin) fueled four-cycle in 1888.[2][1][8]
