• 4191158 Muffler HITACHI Excavator Spare Parts Fitting For EX60WD EX90 EX100 EX100M

• Specification

• Function

1.Noise Reduction:
Features a multi-chambered internal structure with perforated tubes and sound-absorbing baffles to disrupt sound waves, reducing noise by 15–20 dB(A) compared to unrestricted exhaust flow.
Uses resonator technology to target low-frequency engine rumble, compliant with ISO 6395 noise emission standards for construction equipment.

2.Exhaust Flow Efficiency:
Smooth internal pathways minimize backpressure (typically ≤0.8 bar at rated engine load), preserving engine power output.
Outlet diameter slightly larger than inlet (70 mm vs. 60 mm) to optimize exhaust velocity and scavenging.
