Cummins Brand of RV Generators are Ready for CARB SORE 2024 Emission Change

Business Wire
Today, Cummins Inc. (NYSE: CMI) announced a new line of Onan RV
and Commercial Mobile generators 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 reductions targets. 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 (HC) + 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. This feedback
from the oxygen sensor allows the engine to optimize the system for
maximum fuel efficiency and minimum exhaust emissions, a feature
never before available on an Onan generator. The Onan QG 4000i 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
reduction in emissions required to meet the new regulation starting
in January 2024 is significant. The SORE regulation measures HC+NOx
as well as CO across what is called an emissions durability period.
Not only have the emissions limits been reduced on this change, but
the emissions durability period has also been extended. The
regulation does not measure all engines the same, instead they are
categorized based on engine size. Two engine size categories, below
225cc and 225-825cc, represent the majority of spark-ignited RV
generators available on the market today between 2.5kW and 7kW.
The Onan QG 3600 LP, QG 5500 LP, and QG 6500 LP operate on
liquid propane vapor which is a cleaner burning fuel than gasoline;
therefore, it will meet the emissions regulation with no mechanical
changes. The entire portfolio of LP generators will be available in
California beginning January 1, 2024.
The Onan QG 2500i LP and QG 2800i were introduced in 2020
featuring a variable speed electronic fuel injection engine and
inverter technology. With a few more mechanical enhancements and
new engine calibration, this generator will be available in
California in February 2024.
The Onan QG 5500 and QG 7000 generators have EFI variants
available today and are undergoing electronic calibration and
certification development to reach the new targets. There are no
expected hardware changes on this product platform. Only the EFI
variants will be available for sale in California beginning in
April 2024.
While these emissions reductions are very challenging, Cummins
is prepared to achieve them with modern engine technology such as
electronic fuel injection and exhaust aftertreatment. Cummins
innovates technology and products to meet government regulations
related to the emissions of their products. Cummins understands
that sustainability should be everyone’s goal because strong
communities and vibrant economies depend on a healthier planet. The
company has a rich history of providing the RV industry with
reliable power generation, and this is no exception. OEMs and RV
dealers will get a first look at the new product portfolio
beginning in June as Cummins kicks off the Onan Unplugged Tour.
Cummins RV experts are visiting several cities across the country
this summer and fall to demonstrate the new products.
