Cummins said that its new line of Onan RV and Commercial Mobile generators are compliant with California Air Resource Board (CARB) Small Off-Road Engines (SORE) 2024 standards. The current spark-ignited product portfolio will be certified to the new regulations.
The Onan Quiet Gas portfolio has undergone some mechanical changes and engine calibration adjustments to reach the significant emissions reduction targets that come with these new standards. Cummins is also introducing an entirely new generator platform to the Quiet Gas series called Onan QG 4000i.
The Onan QG 4000i replaces the current QG 4000 and features electronic fuel injection, a permanent magnet alternator and inverter technology to provide quieter operation, more fuel efficiency and over 50% reduction in hydrocarbon plus nitrogen oxide (NOx) and carbon dioxide (CO) emissions. The QG 4000i features a closed loop fuel system which utilizes an oxygen sensor to provide critical operating feedback to the engine. It will be available for sale in California in April 2024.
The recently confirmed CARB amendments to the Small Off-Road Engine (SORE) emissions regulation will impact engines powered by gasoline and liquid propane vapor (LP) used in RV generators. The new reglations take effect in January 2024.
