TM 9-2350-247-20-1 THEORY OF OPERATION — Continued 0003 00 EXHAUST SYSTEM AND COMPONENTS Burned fuel fumes from M548A1 carriers are exhausted through the right and left crossover pipes, into the muffler, and out the exhaust pipe. The crossover pipes extend from the rear of the right and left exhaust manifolds to the main exhaust pipe. The crossover pipes are joined together by sliding joints with a ball-and-socket type joint on the main exhaust pipe. The exhaust muffler is bolted in the power plant compartment on the M548A1. An exhaust pipe (exhaust stack assembly) extends above the top of the exhaust well on both carriers. The exhaust pipe has a guard and a cap. The M548A3 major exhaust system parts are the turbocharger, exhaust manifolds, and muffler. The turbocharger is driven by exhaust gases from the engine. The turbocharger helps the engine develop more power and operate more efficiently. The exhaust manifolds carry the exhaust gases to the turbocharger from the engine. The muffler cuts down engine noise and allows exhaust to escape outside the carrier. 0003 00-7 Change 1
