Cummins QSB3.3 Awarded ``Diesel of the Year 2007''

Cummins QSB3.3 engine has received the prestigious title of "Diesel of the Year 2007” from a leading European publication. The award recognizes the innovative technology which enables the 110-hp (82 kW) rated 3.3-liter engine to offer equivalent performance to that of larger 4.0- to 4.5-liter engines – but with a 30 percent smaller and lighter installation package. The QSB3.3 has also been recognized for innovation in North America, named as one of the "Top 100 New Products of 2006” published by Construction Equipment magazine in the December edition. This award list brings attention to the most significant new products of the year with the capability to enhance productivity in the construction industry. Introduced in April 2006 to meet EPA Tier 3/EU Stage IIIA emissions across the 80- to 110-hp (60 to 82 kW) power band, the QSB3.3 is the first industrial engine of its size to incorporate full-authority electronic controls and a High Pressure Common Rail (HPCR) fuel system. Equipped with this advanced technology, the QSB3.3 brings premium performance characteristics previously associated with larger engines, such as the QSB4.5 and QSB6.7, to the compact engine sector. "We are honored to receive these two awards by leading publications in both Europe and North America, reflecting how the QSB3.3 challenges conventional diesel industry thinking on compact engine performance. The awards are a fitting accolade to the Cummins engineers who developed this breakthrough product,” commented Chris Kete, Director of Cummins Light Construction Business. "The innovative benefits of the engine for powering compact equipment were expressed in a marketing theme of ‘Every Rule. Rewritten.’ Now, in pilot installations, we are proving that the engine is rewriting the rules. Our customers are telling us that the QSB3.3 is more powerful, quieter and more sophisticated than they considered possible for such a compact and economical engine,” added Kete.
