TM 9-2815-220-24 THEORY OF OPERATION 0004 00 ENGINE COMPONENTS (Continued) Crankcase Breather and Fire Extinguisher Systems: The engine crankcase breather system is completely enclosed which allows the engine to be submerged without entrance of water and permits the crankcase to be vented. The breather system is vented through the left turbosupercharger exhaust outlet into the vehicle exhaust system. The engine fire extinguisher system is equipped with a fire extinguisher tube located in the "V." The tube has small holes drilled along the entire length to direct carbon dioxide (CO 2 ) in predetermined directions around cylinders, the fuel injection pump, and inter-cylinder components in case of fire.
