Сторінка 84 - ... under a far higher temperature than is possible in a steam engine, consequently the oil intended for use in the motor cylinders must be of such quality that the point at which it will burn or carbonize from heat is as high as possible. While a number of animal and vegetable oils have a flashing point, and yield a fire test sufficiently high to come within the above requirements, they all contain, acids or other substances which have a harmful effect on the metal surfaces it is intended to lubricate.
Сторінка 158 - To find the diameter of circle having given area: Divide the area by .7854, and extract the square root. To find the volume of a cylinder: Multiply the area of the section in square inches by the length in inches = the volume in cubic inches. Cubic inches divided by 1728 = volume in cubic feet.
Сторінка 99 - To find the piston speed of an engine, multiply the stroke in inches by the number of revolutions per minute and divide the product by 6. EXAMPLE. — An engine with a 52-inch stroke runs at a speed of 66 revolutions per minute.
Сторінка 95 - Around the upper end of the piston three or four grooves are cut, and in these grooves the piston-rings fit. The rings are made of cast iron, and the bore of the ring being eccentric to its outer diameter, there is a certain amount of spring in them, and so pressure is caused against the cylinder wall, preventing any of the expanding gases passing the piston. The...
Сторінка 45 - This vessel is immersed in a larger vessel containing water, which forms part of the upper part of the apparatus. A thermometer is suspended with its lower part in the oil. A heating lamp placed under the receptacle containing the water raises the temperature of both water and oil as required. A lighted taper is passed to and fro over the top of the oil as it becomes heated. When the vapor given off by the oil flashes the temperature is noted, and that is termed the " flashing point
Сторінка 48 - Foundations. A concrete foundation, if properly constructed, is the best. While foundations are usually built of brick or stone laid in cement, a foundation may be of concrete, mixed as follows: One part of cement, two parts of coarse sand, five parts of fine crushed stone or coarse gravel. It is desirable to have the capstone from 3 to 6 inches wider and longer than the base of the engine. The depth of the foundation will depend entirely upon the condition of the ground in the vicinity where the...
