Not illustrated. 1918 edition. Excerpt: ...pumps are used for water circulation: the centrifugal, the gear, the plunger, and the vane. The first two are used about equally on the majority of American pleasure cars, the last two having but a few adherents. Q. What is the latest move to improve water circulation? A. The use of a thermostat to control the flow of the water according to its temperature. This device holds the water in the cylinders until a certain predetermined temperature is reached, when it opens and allows the water to flow through the radiator and be cooled. By setting this so that this predetermined temperature is high, but not so high as to be dangerously close to the boiling point, the efficiency of the engine is increased, for a hot engine works better than a cold one and gives more power. Q. What is the purpose of the fan? A. To increase the efficiency of the radiator by drawing more air through it and thus cooling the water more. Q. How is the fan generally driven? A. The belt drive, using a flat or V-type belt is general because of its simplicity, but a few better cars have gear or chain drive; the latter method has increased in recent years particularly with the V-type motors, for in those it has been found easy to drive the fan from a shaft in the immediate vicinity. Questions for Home Study 1. Describe in detail the timing of the Knight motor. 2. Tell how to regulate and check up the valve action from the flywheel marking. 3. How are silent-chain camshaft drives adjusted? How are gears? 4. How is the valve-stem clearance adjusted? LUBRICATION SYSTEMS Q. What is meant when lubrication is referred to? A. In general, the lubrication of the engine, because that is so much more important than the lubrication of any other part or group of parts. If the engine...
