Cummins Engine Company, Inc. has introduced its ISM engine system that features a customer-led design with 2-4% more fuel efficiency and an electronics platform ten times more powerful than its predecessor, the M11 Plus. Customers led a team of engineering, manufacturing, and marketing specialists to a system approach linking product, information, and support. The result is an intelligent and talkative engine that automatically optimizes fuel, lube, cooling, air, accessory, and powertrain performance while tracking vital statistics, along with date and time.
