He could not bring his pride to allow him to seek out Bonbright in person, but sent Rangar as his ambassador. Rangar found Bonbright in his room, reading a book devoted to the ailments of the internal-combustion engine, and acquitted himself of his mission with that degree of diplomacy which his desire for success dictated. "Well?" said Bonbright, as the door opened to admit the ambassador.
Whether on land or sea, fuel oil is preferred to coal because it requires fewer firemen, and back of that, in the man power required in its mining, preparation, and transportation the advantage on the side of oil is even greater. So, too, the substitute for gasoline in internal-combustion engines, whether alcohol or benzol, means higher cost and larger expenditure of labor in its production.
To burn oil under a boiler and convert it into steam releases but 10 per cent of the thermal units in the oil, whereas if this same fuel oil were used directly in a Diesel engine, 30 to 35 per cent of the power in the oil would be secured. Substitute the internal-combustion engine for the steam boiler and we multiply by three or three and one-half the supply of fuel oil in the United States.
Holland's boat, built in 1877, was the first to use a gas-engine as a propulsive medium, but it was not until the final adoption of the gas-engine for surface work, followed later by the internal-combustion gasoline-engine and the use of electric storage-battery for subsurface work, as well as the invention of the periscope and various other devices, that the submarine was developed to a present state of effectiveness, which sees it crossing the Atlantic from Germany, operating off our shores and returning to Germany without being obliged to put into port; which, also, sees it capable of navigating under water at a speed of from seven to nine knots, with torpedoes ready for use in the tubes and guns of effective caliber mounted on deck.
Fuel oil can be largely supplanted by coal, but for the internal-combustion engine there is no quantitative substitute. We have ventured on a great shipbuilding program. Our people are to once again respond to the call of the sea. On private ways and on Government ways ships are being built to go round the world ships that are to burn oil under boilers and produce steam.
There were the sounds of pipes, combined to form the scaffolds, being taken apart for removal. A sling-load of pipe touched the floor and stayed there. The crane's internal-combustion motor stopped. Its operator stepped down to the floor and headed for the exit. Hoists descended and men moved across the floor. Other men scrambled down ladders.
You will notice that the cylinders are enclosed by wide rings of metal, and these rings are quite sufficient to radiate the heat as quickly as it is generated. We have seen that a very important part of the internal-combustion engine, as used on the motor-car, is the radiator, which prevents the engine from becoming overheated and thus ceasing to work.
