This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1912 Excerpt: ...last three are of various types, and they will be best dealt with in a later chapter. 89. A Typical Otto Cycle Engine.--A typical Otto cycle gas engine is shown in section in Fig. 17. Gas and air enter through the casting G, and pass the inlet valve A (operated by cam arrangements not shown in the figure). As the gas and air enter, the piston C moves along the cylinder, being drawn by the connecting rod D attached to the crank-shaft E. After the gases have been allowed to fill the cylinder they are compressed on the return stroke of the piston, are ignited on the inner dead-centre, expand doing work, and on the exhaust stroke the exhaust valve B opens to allow tliem to escape into the silencer. The cylinder is kept sufficiently cool, to enable it to be lubricated, by means of a circulation of water in the jacket space F. 90. Large two-stroke Engines.--There are two well-known Fig. 18.--Diagram of Koerting Engine. Bj and 7/2 Inlet Valves; C Exhaust Valve. designs of large two-stroke engines, both German in origin, viz., the Koerting and the Oechelhauser. The former is made doubleacting and the latter single-acting. In the Koerting Engine, illustrated diagrammatically in Fig. 18, the piston A is made unusually long, and by alternately covering and uncovering the exhaust post C is itself a part of the valve gear. The mixture of gas and air is admitted alternately at Bj and B.2 from the pump cylinder. If there has just been an explosion at the left-hand end of the cylinder, the piston will move to the right, and the gases will expand, doing work. By the time the piston has got to the end of the stroke, it will have uncovered the exhaust port C, and the burnt gases will rush away. At this point the inlet valve Bj is opened, and fresh air and gas are pumped in. T...
