DZ91259540009 Muffler is a core exhaust part for Shacman F3000 heavy trucks. It has two key functions: reducing exhaust noise (meets road vehicle noise standards) and heating intake air or cab-this heating feature ensures driver comfort and engine performance in cold conditions. Its compact square shape fits the F3000's under-chassis, saving space while maintaining stable performance, critical for long-haul logistics, construction and other heavy-use scenarios.
It works with the truck's exhaust manifold and heating loop. When the truck operates, hot exhaust enters the muffler: internal baffles reduce noise by slowing gas flow and disrupting sound waves. Meanwhile, the built-in heating element (or heat exchanger) transfers exhaust heat to intake air (prevents cold air from affecting combustion) or cab heating system-keeps cab comfortable in cold weather (-25°C to 0°C). It withstands harsh conditions: high exhaust temperatures (up to 600°C), road vibrations during long drives, and dusty/rainy environments (construction sites, rural roads).
Made of high-temp materials with precision welding, it passes strict noise reduction, heat transfer and durability tests. The square shell has good impact resistance, and internal heat exchange parts transfer heat efficiently-no heat loss or noise leakage even after long-term use.
Key Specifications
- Part No.: DZ91259540009
- Product Name: Shacman F3000 Muffler (with heating)
- Position: Core of F3000's exhaust system. Connects to exhaust manifold, heating pipes, and cab/intake to cut noise and heat.
- Main Materials:
- Shell: High-temp carbon steel (impact-resistant, resists exhaust corrosion)
- Internal baffle: Stainless steel (heat-resistant, no warping at high temps)
- Heating element/heat exchanger: Copper-nickel alloy (good heat transfer, anti-oxidation)
- Sealing gasket: Heat-resistant rubber (seals tight, stops exhaust leaks)
- Performance
- Noise Reduction: Cuts exhaust noise by 25-35 dB (meets GB 1495-2002 vehicle noise standards)
- Heating Capacity: 3-5 kW output-raises cab temp by 15-20°C in 10-15 mins at -20°C; keeps intake air above 5°C to improve cold starts
- Temp Range: -30°C to 600°C (works steady in extreme cold and hot exhaust)
- Durability: Passed 500-hour high-temp cycles and 300,000 km road tests. Meets Shacman Q/SC1052-2024 for exhaust parts.
- Safety & Compliance
- Follows GB 1495-2002 (Road Vehicle Noise Limits & Measurement)
- Meets ECE R49 (UN exhaust system/emission control rules)
advantages
- Dual-Function: Combines noise reduction and heating-no need for extra heaters, saves space and energy
- Square Design: Fits F3000's under-chassis perfectly, no mods to original truck structure
- Long Life: High-temp materials and anti-corrosion treatment-lasts 200,000-250,000 km on average, cuts replacement and maintenance costs
- Reliable Heating: Fast heat transfer-fixes cold cab and tough cold starts in cold areas
- Easy Install: Matches F3000's original size, uses standard fasteners for exhaust/heating pipes. Pros can install in 20-30 mins.
