| New generator sets from Cummins Power New diesel generator sets from Cummins Power Generation, rated at 80, 100, 125 and 150 kW, are EPA Tier-3 compliant and suitable for supplying standby or prime power to commercial buildings, hotels and office complexes. Model DSGAB is rated at 125 kW and model DSGAC is rated at 150 kW. Models DSGAA, DSGAB and DSGAC feature the Cummins six-cylinder QSB7 turbocharged charge air cooled diesel engine. The QSB7 engine is a variant of on-highway engines used in the popular Dodge RAM pickup truck line. This diesel engine has been modified with optimized air- and fuel-handling systems for high duty cycles and variable loads at constant speed that are required in a generator application. Generator sets powered by the QSB7 engine include a mounted cooling system that enables the product to perform at high ambient air temperatures and saves installation costs for the customer due to simplified facility design requirements for rejected heat. Model DSFAE features a Cummins QSB5 in-line four-cylinder turbocharged CAC Tier 3 diesel engine mounted on a compact platform. The low-emissions design of the engines featured on the generator sets reduces oxides of nitrogen and particulate matter through in-cylinder combustion technology that uses new combustion chamber geometry and advanced electronic fuel injection. These design changes are coupled with full-authority electronic engine controls for tighter control of engine operating parameters. The overall benefits are reduced emissions without a reduction in power output, and the elimination of complex and expensive mechanical systems such as variable geometry turbochargers. The standard PowerCommand digital electronic control on the generator sets is an integrated system that combines engine and alternator controls for high reliability and optimum performance. write your comments about the article :: © 2006 Construction News :: home page |
