	The engine has much in common with modern ones. It has two [[Cylinder (engine)\|cylinders]], a [[carburetor]], a familiar arrangement of valves and [[cam]]s, and Morey even thought of using [[spark plug\|electric sparks for ignition]] (although there is no indication that he ever did this and it had already been done). However, unlike modern engines, the explosion did not directly provide power. Instead, the explosion expelled air from the cylinder through a one-way valve. The cylinder was cooled by a water jacket and water injected into the combustion chamber after it fired. The cooling gasses caused a vacuum and atmospheric pressure drove the piston. Morey did mention trying direct action, and elaborated on it in other descriptions. However, his method was more complicated and possibly less efficient because it used more of the engine’s stroke to draw in fuel.		The engine has much in common with modern ones.

	Morey demonstrated his engine in New York and Philadelphia and there are eyewitness reports for both. In Philadelphia, he demonstrated it powering a boat and a wagon. Unfortunately, when he decided to demonstrate the car on the street, he fell off after starting the engine and the vehicle powered across [[Market Street ~~(Philadelphia)\|Market Street]]~~ into a ditch. This was the second car ride in the world, and the first in the United States. Despite these mostly successful demonstrations, Morey could not find a buyer, and became frustrated. A letter from Reverend Dana of Orford written in October 1829 tells of Morey’s trip to Baltimore, “I am told, the Capt. Is determined to make one more vigorous effort, to sell his patent right for some of his modern inventions [he later singles out the vapor engine], and if he does not now succeed, he will give the matter up, and return to Orford, to spend his days in quiet.” Morey did not find a buyer, and as he was then in his late 60s, it made sense to stop traveling up and down the east coast and call it quits.

	While the engine was state of the art, it was not novel in many respects. Morey seemed aware of contemporary internal combustion work – Hardenberg, who wrote a book on Morey’s engine, adeptly noted that in his 1825 draft Morey “stated that he named his invention ‘vapor engine, to distinguish it from the… gas engine.’” However, Hardenberg concludes that Morey could only have known of three engines similar to his. He never mentioned them, and Hardenberg concludes that they did not influence Morey. His internal combustion engine is the first documented in the United States, and his use of liquid fuel and a heated surface carburetor was new. Another interesting feature was the wire mesh used to prevent the combustion from reaching the carburetor. This feature was reinvented and patented again in 1872 because the patent office had lost Morey’s patent in the 1836 patent office fire.
