Lane had made exceedingly clear how the present loss in a gas-engine was occasioned, and had also shown how, in the future development of the engine, the loss might be saved, and the engine rendered more efficient. Mr. Lane had said.
Lane had given a very clear description of the elementary principles of thermo-dynamics in their relation to the gas-engine and the steam-engine. There was very little in the paper to raise discussion; but Mr.
The 71 per cent. escaping as heat may be utilized in place of other fuel; and with the first hot-air engine I ever saw, it was employed for drying blocks of wood. In the same way, the unconverted heat of the exhaust steam from a high-pressure engine, or the heated gases and water passing away from a gas-engine, may be employed.
I have not said anything of the thermal principles involved in the construction of these engines, as they are precisely the same as those affecting the subject of the present paper. Before explaining the principle upon which the gas-engine and every other hot-air engine depends, I shall remind you of a few data with which most of you are already familiar.
The best gas-engine at present made would have been an expensive thing to supply with gas at the prices current in 1820, even if the resources of mechanical science at that date had been equal to its construction; which we know was not the case. Still, this consideration was not known, or was little valued, by Mr. Cecil and his contemporaries. It was not long, however, before Mr.
It must be kept in mind, too, in analyzing the causes of the automobile's amazing expansion, that it is the first real improvement in individual transportation since the chariot rattled around the Roman arena. The horse had his century-old day, but when the motor came man traded him for a gas-engine.
Here Edison and a few of his assistants from Menlo Park installed immediately in the basement a small generating plant, at first with a gas-engine which was not successful, and then with a Hampson high-speed engine and boiler, constituting a complete isolated plant. The building was wired from top to bottom, and equipped with all the appliances of the art.
Although good coal may yield 14,000 units by its combustion, only about 11,000 of these reach the boiler; so that the ratio of the useful heat is 11/19. The thermal efficiency of the best non-condensing engine to that of the gas-engine is in the ratio 4/22. Multiplying together these two ratios, we get
Fyfe," he said. "A gas-engine man would 'a' fixed that in five minutes. Took me two hours to find out what was wrong. It'll be a heck of a job to fetch Cougar Bay now." But by luck Barlow made his way back, blundering fairly into the landing at the foot of the path that led to the bungalow, as if the cruiser knew the way to her old berth.
During all this time I kept my position with the electric company and gradually advanced to chief engineer at a salary of one hundred and twenty-five dollars a month. But my gas-engine experiments were no more popular with the president of the company than my first mechanical leanings were with my father. It was not that my employer objected to experiments only to experiments with a gas engine.
