BlueCAT SSI 3-Way Catalytic Converters

BlueCAT SSI 3-Way Catalytic Converters

For use with small spark ignited (SSI) engines, the BlueCATTM SSI emission control system is a direct-fit replacement for OEM mufflers. 

Regardless if you’re a worker, manager or a health and safety professional, the BlueCATTM SSI is an emission control product designed to improve job site health and safety conditions. 

Mindful of worker health and safety, the cost effective and easy to install BlueCATTM SSI emission control solution is engineered and manufactured to integrate with all leading equipment and engine manufacturer designs.

Great at reducing harmful emissions, the BlueCATTM SSI system is ideal for use in household and commercial applications,
including lawn and garden equipment, utility vehicles, generators, and variety of other construction, farm, and industrial equipment.

• BlueCAT™ Small Spark Ignition (SSI) engine emission control system utilizes the same technology which has been verified and proven by California Air Resources Board (CARB) in 1000's of installations on Large Spark Ignition (LSI) engines
• Ideal for LPG, CNG and gasoline engines used in small off-road engine applications (construction, utility, material handling industries)
• The BlueCAT™ SSI catalytic mufflers match or surpass the noise attenuation performance of the original muffler

BlueCAT™ SSI engine emission control system is a direct-fit replacement for OEM-designed muffler simplifying installation and saving time. The emission control catalyst is built into the BlueCAT™ SSI muffler to match the same OEM envelope for size, sound attenuation, back pressure characteristics with the addition of superior emissions performance.

In the BlueCAT™ SSI 3-way catalyst, reactions between Carbon Monoxide (CO), Hydrocarbons (HC), and Oxides of Nitrogen (NOx) result in the simultaneous removal of all three major exhaust pollutants. One of the fundamental chemical reactions occurring in the catalyst can be written as follows:

CO + NO = CO₂ + 1/2 N₂

Concentrations of pollutants in the exhaust gas depend on the fuel mixture composition. At lean fuel mixtures the exhaust gases contain little Carbon Monoxide (CO) or Hydrocarbons (HC) but high concentrations of Oxides of Nitrogen (NOx). Rich mixtures produce high concentrations of CO and HC with little NO_x. In order to achieve high simultaneous conversions of CO and NO_x, their concentrations in the exhaust must be in stoichiometric proportion, as illustrated by the above equation. If the air-to-fuel mixture is not stoichiometric, conversion of either NO_x or CO will deteriorate, as shown in the diagram below.

CO emissions are typically reduced by over 98%. HC are reduced by 95%. The characteristic smell of propane exhaust is virtually eliminated.
