The exhaust pipes or nozzles are made of cast a single nozzle is used, such as shown insection in Fig. 36, having a partition at its base. Inother cases two nozzles are used, which are generallycast together, as shown in section in Fig. 37. Fig. 38 is a plan view of single and double or bushings are fitted in the outlet openings ofthese nozzles for the purpose of reducing their areaand thereby increasing the draft. These bushings aremade of various diameters and are easily removed inorder to substitute others with larger or smaller open-ings as they may be required. If the exhaust orifice is Figure 35 THROTTLE AND DRY PIPE 9i too large the draught through the tubes will not besufficient. On the other hand, if the area of theexhaust opening is reduced too much the back pressurein the cylinders will be increased, thereby limiting thepower of the engine. It is therefore necessary that. oil III I 38 >v r
