www.chinabuses.org: Diesel engine manufacturer Cummins Inc. introduced a new range heavy-duty power, called the next-generation X Series. With the lineup expanded to three X engines, and ratings extending from 350 hp to 605 hp, this represents the broadest and most capable heavy-duty engine range that Cummins has ever made available to the North American truck and bus market.

The X engine platform builds on the success of the current heavy-duty engines, taking on new names to reflect the evolution and introduction of the product platforms to meet Phase 1 greenhouse gas (GHG) and fuel-efficiency standards, to be fully implemented in 2017.
By taking highly innovative approaches, combined with a series of finely tuned improvements on existing technologies, the X15 brings unmatched performance and fuel efficiency, with the implementation of an optimized compression ratio, air handling system and cam profile. The X12 redefines the meaning of medium-bore power with by far the highest power-to-weight ratio of any heavy-duty engine. All three engines are integrated with the revolutionary Single Module™ aftertreatment. Up to 60 percent smaller and 40 percent lighter than modular aftertreatment systems, the Single Module is capable of taking DPF ash cleaning events to as much as 800,000 miles on the X15.
The X15 Performance Series is ideally configured for heavy-haul and vocational trucks, with a 485 hp-to-605 hp ratings range, while the X15 Efficiency Series is tailored for line-haul and regional- haul applications, with a 400 hp-to-500 hp range. The X12 medium bore engine has a 350-to-475 hp range for regional-haul, intracity delivery and vocational trucks. All three engines will be manufactured at the Cummins Jamestown Engine Plant.
