REASONS FOR LOSS
 OF POWER GIVEN;
 REDUCTION METHOD

NNOHtiHueQ IIOill page OUe) hard to keep the power dissipation under control, as we shall show.
 The first item on our list, power lost through dissipation in the cooling wa ter, can scarcely be controlled by the ordinary car owner. Within the past year or two engineers have taken up seriously the problem of reducing this | item of waste. By means of thermo- l static control it is now possible to keep the temperature of the engine at or near its point of maximum efficiency. Heat is simply a form of power. But unfortunately the nature of the inter- nal combustion engine prevents more than a certain degree of temperature being utilized, because beyond that point the oil film, the protecting lu bricant would be broken down and the engine would be quickly ruined. How ever, by the use of thermostatic de- vices, designers have been able to re- duce the amount of heat, which means power, wasted in the cooling water. What he can do, however, is to see that there is no leakage from the en- zine; this includes gas leakage, ignition leakage, oil leakage. etc. The gas- keting of the cylinder head, if there is such, must be good all the time and there must be no leaks at the plugs or petcocks. In gasketing the head. be sure to see that the gasket itself is perfectly clean and is mounted on clean surfaces. There must be no hicks or dents in metal or gasket. The head must be frightened carefully to avoid springing. It is admirable to give the threads of the spark plugs. valve plugs and any other threaded devise in the engine, a thin coating of stove black ing, which prevents or stops leakage and also makes removal of the parts easy at any future time.
 | It must not be forgotten that the various accessories and devices To- | cated on and driven by the engine, consume power; in some cases as much as six per cent of the total. Add to this the inevitable friction generated by the various moving parts of the en- zine and we get tidy total. The car owner cannot cut down the consump- tion of power here, but he can keep it at it's normal point by seeing that all | these parts and accessories have a li- | beral quantity of lubricant of the prop CT grade and quality. The careful study of and attention to the directions on the fabrication chart are the safe- 1 guard here.
 | Again, carbon deposits in the com- bustion chamber are excessive wasters of power. A vigilant eye in this direc- ton and removal of such deposits be- fore they have a chance to reach seri- ous proportions is necessary. In some cases owners who have excessive car bon trouble may be well advised to install water feeding device on their engines after the cylinders have been thoroughly cleaned Water injected this way in the form of steam tends to prevent the formation of carbon de- posits in clean cylinder.
 There is one form of power waste that is not to be excused and that is through the use of too rich a mix ture. This simply means that more gasoline than is necessary is being burned up and going out of the cx- haust possibly even in the form of liquid. And what is this but the most direct and criminal sort of waste, which the owner can stop any time he desires.
 In addition any liquid fuel in the combustion chamber may work down past the piston rings, into the crank
 case, and there contaminate the oil and increase the loss further by low ering the lubricating efficiency.
 The clutch wastes little power as
 long as it is running properly, but the minute it gets out of order and slips, it fairly burns power up. Keep the
 clutch properly adjusted and lubricate
 the thrust bearing and throwout col l.
 lar at stated intervals. A burned or dry throwout 'onllar may cAliaA . flran
