COLUMBUS, Ind. — Steve Charlton, vice president and chief technical officer of Cummins Inc.’s engine business, retired on Tuesday.

Charlton is succeeded by Jennifer Rumsey, who has been named vice president of engineering for the company’s engine business.

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

Charlton joined Cummins in 1993. His notable efforts during his career with the company included working on early plans for the V-8 light-duty diesel engine and leading the development of heavy-duty engine products to meet the 2007 EPA emissions standards.

Rumsey joined Cummins in 2000. In her new role to succeed Charlton, she will focus on new opportunities for growth, including the launch of new platforms, continued development of existing platforms and improving product quality. She most recently served as vice president of engineering for the company’s heavy-, medium- and light-duty engine business.

"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," Freeland said.

Another Cummins veteran, Jeff Jones, retired on Monday. Jones, who was vice president of North American engine business and marketing communications, joined the company in 1977.
