Truck engine manufacturer Cummins announced on Monday that Steve Charlton, vice president and chief technical officer, engine business, plans to retire from the company July 1. It also announced that Jennifer Rumsey has been named vice president, engineering for the engine business, succeeding Charlton.

"In his more than 20 years with the company, Steve has provided invaluable technical expertise and leadership," said Rich Freeland, president, engine business and vice president, Cummins Inc. "He has left a profound mark on our company, and his contributions will always be valued and remembered."

In her new role, Rumsey, who joined Cummins in 2000, will focus on new opportunities for growth, including the launch of new platforms, continued development of existing platforms and improving product quality, according to the company.

"Jennifer brings tremendous expertise, and has successfully worked across business units and regional boundaries, and she will no doubt continue to be successful in this role," said Freeland. "Jennifer's ability to deliver innovative products fit for different global markets that our customers depend on will be critical to the continued success of the engine business and Cummins as a whole."

Rumsey most recently served as vice president, engineering for the heavy-, medium- and light-duty engine business. Prior to the creation of the combined heavy-, medium- and light-duty engine business, she led heavy-duty engineering and played key roles on a number of significant projects and initiatives within the engine business.

Rumsey has also served in other roles for Cummins. Prior to joining the company, she worked at a fuel-cell startup company in Cambridge, Mass.

Rumsey received a bachelor of science in mechanical engineering with highest honors from Purdue University in 1996 and a master of science in mechanical engineering from the Massachusetts Institute of Technology in 1998.

Charlton joined Cummins in 1993 as the director of advanced engineering, working on the early plans for the V-8 light-duty diesel engine. He became executive director, research in 1999, and was named Executive Director, Advanced Engineering in 2001. In 2004, Charlton was appointed technical leader on the project to develop the heavy duty engine products to meet the 2007 EPA emissions standards. He was named vice president of heavy duty engineering in 2008 and went on to become vice president and chief technical officer for the engine business in 2010, the role he holds today.

Prior to joining Cummins, Charlton worked as an engineer at the General Electric in the United Kingdom and also taught engineering at Staffordshire University and the University of Bath. He earned a bachelor's degree in mechanical engineering from Staffordshire University in the U.K. and a doctorate in mechanical engineering from the University of Aston.

Charlton was elected a fellow by the Society of Automotive Engineers in 2005 and the Institute of Mechanical Engineers in London in 2009. Charlton was awarded an honorary doctorate in engineering from the University of Bath in recognition of his leadership in engine technology.
