EXHAUST SYSTEM
5.3.3
MUFFLER LOCATION
Locate the muf
fl
er close to the engine results for best overall noise reduction.
5.3.4
SYSTEM INSULATION
Exposed exhaust system parts should not be near wood or other
fl
ammable material. Exhaust
temperatures may exceed 700°C (1292°F).
BURN
To avoid burn injury, an exhaust system inside a building
should be covered with screen or shield.
Insulating the system will reduce the heat radiation and the noise level caused by the exhaust
system. For use of insulating material such as exhaust blankets on the turbocharger and exhaust
manifold, consult with Detroit Diesel Application Engineering.
