Cummins has launched a Tier 4 website to provide equipment users with an early insight into the performance and operation of field test installations. This comes ahead of the January 2011 effect date for EPA Tier 4 Interim and EU Stage IIIB low emissions engines above 129 kW. The www.tier4.info site has content based on over 40,000 hours of accumulated experience of Tier 4 powered equipment from customer field tests and evaluation tests by OEMs.“The clear message from our field test customers is that they prefer using equipment re-powered with Cummins Tier 4 engines, compared with the equivalent Tier 3 engines they replaced,” said Hugh Foden, Executive Director of Cummins Off-Highway Business.“Field test equipment operating on commercial service has demonstrated improved engine response and lower fuel consumption, while achieving the same exceptional levels of uptime achieved by the Tier 3 installations.“The website provides an ideal way of sharing the experiences of Cummins field test equipment operators with others in the industry who would like to understand more about the performance of Tier 4 powered equipment compared with Tier 3,” said Foden.The website will continue to be populated with additional information as Cummins nears 100 completed Tier 4 installations, varying from wheeled loaders to a yard spotter, snow groomer and excavators, to a rock drill. It is expected to provide a useful educational resource for OEM dealers, rental companies and equipment operators. Visitors can learn about the next generation technology, including details about Cummins exhaust aftertreatment and Direct Flow air cleaner.It features a customer testimonial video, the latest product brochures, regulatory details and a Tier 4 fuel saver calculator.
