Page 2 - The British Thermal Unit (BTU) is the amount of heat required to raise one pound of water one degree Fahrenheit.
Page 43 - ... brought back to their normal positions and the starting cylinder functions normally. In other engines compressed air is admitted to the cylinder during the expansion stroke by manual operation of a special valve. After two or three admissions during successive cycles, the engine will attain speed enough to permit the opening of the gas valve and the commencement of the cycle. With engines up to...
Page 5 - Engine. half stroke the valve closes the port and a spark from an induction coil passes between the terminals n of the electric igniter, exploding the mixture and raising its pressure to (50 or 70 Ib.
Page 1 - The specific gravity of a gas is the ratio of the weight of a given volume of gas to the weight of an equal volume of dry COr-free air measured at the same temperature and pressure.
Page 33 - The method ensures a good contact, produces a very hot spark, keeps the contact points clean, but wears them out quite rapidly. Provision must be made for adjustment, otherwise the timing will alter with the wear of the points. The rubbing surfaces can be of iron. The igniter gear of an engine with hammer break ignition is shown in Fig.
Page 8 - ... together so as to secure a thorough admixture. In a large number of producers, the air is forced into the producer by a steam blower, which is simply an air-injector. Since a small quantity of steam must carry in a large quantity of air, the area of the surface of contact between the two should be as large as possible, for "the quantity of air delivered per minute by a steam jet depends upon the surface of contact between the air and the steam, irrespective of the steam pressure, up to the limit...
Page 5 - H uncovers the exhaust port, and keeps it open throughout the whole of the return stroke, so that all the products of combustion are expelled to the atmosphere. A similar cycle of operations occurs on the other side of the piston. In Fig. 1, the valve G is just opening the port at the left, so that admission may take place there; and the valve...

The automatic feed consists essentially of coal tank and a revolving eccentric chute which spreads the coal out over the surface of the fuel as shown in the illustration. The steam blower is placed in a horizontal position as is shown in the lower left-hand corner of the illustration. Fig. 12 shows the operating floor of a battery of 52 Morgan gas-producers. A small, auxiliary coal tank is placed over and above the feeding mechanism of each producer. These...
Page 5 - II to the atmosphere. As the cylinder rapidly becomes very hot, it is provided with a water jacket. The series or cycle of operations which takes place in this engine is as follows: During the first part of the stroke the admission valve G uncovers the port a so that a mixture of air and gas enters the cylinder, filling the space behind the piston. At Fig.
Page 39 - A and which can rotate them so as to cover up more or less of the lengths and therefore of the areas of the gas and air ports respectively. With the two levers in constant positions the areas for admission of gas and air to the cylindrical valve A will be fixed, and consequently the strength of the mixture will be constant. The actual amount of the mixture entering the cylinder is controlled by the governor B, which works an internal cylindrical valve in such way as to throttle the discharge port...
