Indiana: Improving Diesel Engine Performance for Trucks

Project Overview
Positive Impact: The Cummins plant expects to create 300 new jobs over the next several years.
Location: Indiana
Partners: Cummins
EERE Investment: $53.8M
Clean Energy Sector: Sustainable transportationPDF

Cummins, the world’s largest diesel engine manufacturer, received funds from EERE to research advanced engine technology for heavy-duty and light-duty vehicles. Cummins’ work on Class 8 heavy-duty trucks includes the development and demonstration of a highly efficient and clean diesel engine, an advanced waste heat recovery system, and a fuel cell auxiliary power unit to reduce engine idling for an aerodynamic Peterbilt tractor and trailer combination. Cummins’ work on light-duty vehicles focuses on developing a fuel-efficient, low-emissions diesel engine that is 40% more fuel efficient than conventional gasoline technology, while meeting 2010 EPA emissions standards. Cummins contributed $55.3 million to these projects.

Cummins recently announced that its Columbus Engine Plant is preparing to manufacture the Cummins 5.0L V8 Turbo Diesel engine for Nissan’s next-generation Titan pickup truck. This truck’s fundamental design is based on technology development EERE co-funded from 1997 through 2004. In addition to meeting EPA emissions standards and cutting carbon pollution—supporting the President’s Climate Action Plan—the Cummins plant expects to create 300 new jobs over the next several years.


The Vehicle Technologies Office (VTO) develops and deploys efficient and environmentally friendly highway transportation technologies that will enable America to use less petroleum. These technologies will provide Americans with greater freedom of mobility and energy security, while lowering costs and reducing impacts on the environment.
