32 Combustion Retarding Apparatus* curve lfo.5 the desired Tolume of air could beeapelled by noting the manometer reading* Itwas also feasible to ascertain the air tight-ness of the system by introducing a differencein pressure between the system amd the atmos-phere smd observing how much loss in pressurewould tSLke place in a given time* One leg ofthe manometer was connected to the apparatus andthe other leg left open to the atmosphere* Thedifference in reading on the manometer shows thedifference in pressure of the combustion chamberand atmospheric pressure* Induct ion Coil An induction coil as shown in figure 6 was connected to a storage battery thru its primary coil and the secondary to the spark plug*

34 Combustion Retarding Apparatus. CALIBRATION OF APPARATUS. Volume The volume of the apparatus was determined by water displacement. Thejoints were painted and made tight, and theblind flanges bolted on the ends. Water waspoured into the observation port with a standardU.S.Gallon measure and a graduated flask. Theapparatus was found to contain 34,430 o.c. Oas-air . . Mixture Assuming that gas and air are chemically inert, the following method was used for determining the percentage mixture: Let V-i- Volume of system in c.c. below^ atmospheric pressure. Pi- Pressure of V below atmospheric. V - The volume of air plus gas in c.c.2 subjected to pressure Pg. P^_ Atmospheric pressure. Y-r Vo-Vt or volume of gas in c.c. tobe added to the system. 35 Combustion Retarding Apparatus. The tentperature ramaining constant.Lst the volume of system be V^^ at P^^ and Voat P , then P = ^1 ^ ^1 , Since thesystem is rigid there must be added a certainvolume to make up the difference between V^^and Vg* T
