The exhaust system of the Caterpillar D6H bulldozer is made of high-temperature and corrosion-resistant steel, with a total length of 3.2 meters. The inner pipe diameter is 230 millimeters and the wall thickness is 5 millimeters, capable of withstanding exhaust gas temperatures up to 720 degrees Celsius. Its internal design features multi-stage chambers to reduce noise and optimize gas flow. Connections use standard SAE flanges with heat-resistant gaskets, providing resistance to vibrations exceeding 900 Newton-meters. Anti-rust coating and heat-resistant paint extend the exhaust’s service life to over 6,500 operating hours, ensuring full compatibility with the D6H diesel engine.
The thermal and acoustic performance of the D6H exhaust complies with EPA and ISO standards, with a pressure drop along the path of less than 20 kilopascals. The internal structure includes a turbulent flow network to reduce particulate matter and guide exhaust gases toward the rear exit. The total weight of the exhaust without auxiliary components is approximately 145 kilograms, installed using two M12 bolts and four M10 bolts. Its modular design allows replacement of damaged sections without removing the entire assembly, improving exhaust efficiency by up to 91 percent.
