Description
Eliminate hazardous exhaust fumes, raw fuel odors, and carbon monoxide inside enclosed repair shops and equipment trailers. The Bartell Morrison BlueCAT 3-Way Catalytic muffler replaces standard factory exhaust mufflers on Honda GX200 commercial engines. This emission-control muffler utilizes a ceramic catalytic core. It requires proper engine carburetor tuning to prevent unburned fuel from overheating the internal catalyst.
Heavy-duty stainless steel forms the welded exterior muffler shell, resisting extreme internal exhaust temperatures without burnout or corrosion. An internal ceramic honeycomb core coats with platinum, palladium, and rhodium catalyst metals to oxidize harmful engine emissions. The three-way catalyst reduces carbon monoxide, hydrocarbons, and nitrogen oxides by up to 95 percent during operation. Direct factory mounting flanges bolt straight onto Honda GX200 cylinder heads.
Key Features of Bartell Morrison 21156
Facility contractors and mechanics install this catalytic muffler on power trowels, log splitters, and generator engines inside enclosed bays. The catalytic conversion keeps indoor air breathable.
- Three-way catalytic conversion reduces toxic carbon monoxide and hydrocarbons by up to 95 percent
- Engineered specifically to replace factory exhaust mufflers on Honda GX160 and GX200 engines
- Stainless steel welded outer casing resists corrosion from high-temperature exhaust condensation
- Internal ceramic honeycomb monolith coated with precious metals maximizes catalytic action
- Direct bolt-on replacement uses factory cylinder head exhaust stud locations and gaskets
- Maintains engine horsepower and torque performance with minimal exhaust gas backpressure
- Meets strict indoor industrial air quality guidelines and OSHA equipment emission rules
Exhaust Emission Dynamometer Telemetry
Exhaust gas analysis verifies 96 percent reduction in carbon monoxide emissions on Honda GX200 engines running at 3600 RPM. Exhaust backpressure measures under 0.4 PSI, preserving full 6.5 HP engine output. Catalyst internal bed temperatures reach 650 degrees Fahrenheit within three minutes of engine start. Outer stainless steel heat shield temperature stabilizes at 310 degrees Fahrenheit. Acoustic sound suppression matches factory sound at 78 dBA.
Catalytic Engine Operation Safety Filters
Bolt the muffler flange to the cylinder head using a fresh high-temperature exhaust gasket and torque nuts to 18 foot-pounds. Ensure the engine carburetor runs on proper fuel mixture; rich fuel settings dump raw gasoline that melts catalyst cores. Do not operate equipment in unventilated spaces without functioning air quality monitors.
- Muffler mounting flange nuts require torque checks after the initial five hours of operation
- Engine air cleaner elements require regular cleaning to prevent rich unburned fuel conditions
- Spark plug gap and condition demand inspection every fifty hours to stop cylinder misfires
