General Motors is the recipient of a Department of Energy grant for $7.7 million to accelerate the development of fuel-saving and clean engine technologies.
“The DOE grant helps accelerate our efforts in bringing breakthrough technologies to production that optimize fuel efficiency, emission, and vehicle performance,” said Dan Hancock, vice president of GM’s global powertrain engineering. GM will use the DOE grant for four specific technologies it hopes to bring to market in the near future. The project integrates lean combustion technologies, stop-start systems, active thermal management, and an innovative selective catalytic reduction system necessary to bring lean combustion emissions down. By combining these technologies, GM says it will be able to reduce fuel economy by at least 25 percent and continue to meet ever-stricter emissions standards. According to GM, the first product from this investment will be an advanced 2.4-liter Ecotec I-4 and a six-speed automatic transmission. This engine could appear as soon as 2011 in the Chevrolet Malbu, but the combination could be used in a number of different applications throughout GM’s portfolio.
