Cummins has begun production of 6-cylinder engines certified to meet Tier 4 final regulations as well as equivalent standards in Canada and Stage IV in Europe. Engine production across a broad 190-hp to 675-hp output will increase during the course of the year as off-highway equipment manufacturers release machines ready to meet the near-zero emissions standards that took effect Jan. 14.

The 6.7- to 15-liter Cummins engines will be featured in a wide range of Tier 4 final construction machines, material handling equipment, power packs and cranes set to debut at ConExpo 2014 in March in Las Vegas.

“By making an early start with Tier 4 final development, we were able to undertake our largest ever field test and OEM installation program, extending to more than 70 machines operating under the most demanding duty cycles and challenging geographies, including high altitude, high humidity, extreme heat and cold,” said Hugh Foden, executive director – Cummins off-highway business.

The full range of engines will be on display at Cummins’ booth at ConExpo.
