Cummins announced it will double the production capacity of its 3.3-liter engine to meet a major growth in demand from manufacturers of 4-cylinder-powered compact equipment across the 55 hp to 120 hp (41-90 kW) power range. A new manufacturing operation for the 3.3-liter engine located in Chennai, India—established in collaboration with Simpson & Co. Ltd.—is scheduled to commence production in July this year, with engines available for the Indian market and for export to customers worldwide.

The Chennai manufacturing operation will initially focus on producing the mechanically controlled B3.3 engine, spanning a 55 hp to 85 hp (41-63 kW) power range. Concurrent with the new build capacity in India, the Komatsu-Cummins joint venture plant at Oyama in Japan will also ramp up production of the electronically controlled QSB3.3 engine, extending across an 80 hp to 120 hp (60-90 kW) power range.

“By doubling our 3.3-liter production capacity, Cummins will be well positioned to realize new sales opportunities with compact equipment manufacturers worldwide, while also preparing us for sales growth with the introduction of Tier 4 engines and aftertreatment starting next year,” said Hugh Foden, Executive Director—Cummins Off-Highway Business. “The remarkable popularity of the B3.3 and QSB3.3 engine has surpassed even our highest expectations. Demand for the 3.3-liter engine has rapidly recovered from the industry downturn in 2009, and we anticipate a new peak volume in 2011, with customer orders increasing by around 100 percent compared with 2010” added Foden.

To meet the forthcoming Tier 4 emission regulations, the B3.3 and QSB3.3 will utilize an exhaust aftertreatment system designed for each engine by Cummins Emission Solutions. For Tier 4 Interim in 2012, the QSB3.3 will utilize the “Cummins Compact Catalyst” aftertreatment, with no particulate filter. The B3.3 will meet Tier 4 final in 2013 by replacing the exhaust muffler with a particulate filter.
