CONSTRUCTION OF THE DIESEL ENGINE 113 The method of scavenging is identical with that employedin the marine engines and described later. (Scavenge valvesin the cjdinder head are dispensed with, ports being providedat the bottom of the cylinder, uncovered by the piston,whilst auxiliary valve-controlled air-ports are also arrangedjust above the main ports. Only three of the cyhndershave starting valves, and in each case there are two valves inthe cylinder head, whilst each cylinder has one fuel inletvalve. No other valves are required. An important feature of the engine and one which is muchadopted in various marine designs, is that the cylinder issupported by steel columns and not by a cast-iron cylinder liner itself is quite free to move downwardduring expansion, which is a necessary safeguard in largecylinders. The weight of this engine complete is some 4r0 tons, andits length a
