Forklift Internal Combustion Engine Muffler Type
Muffler is one of the most effective ways to reduce exhaust noise. Forklift mufflers include resistive, resistive and impedance compound mufflers. Resistive mufflers are mainly used in the exhaust system of internal combustion engine forklifts. Resistive mufflers include expansion cavity mufflers, resonant cavity mufflers, and small holes mufflers.
