GM touts diesel-like engine

Posted Thursday, May 21, 2009, 2:00 pm in Employee News

General Motors Corp. is closer to building a gas engine that runs like its more-efficient diesel counterpart, The Detroit News reported.

GM officials showcased the HCCI four-cylinder engine (HCCI stands for homogenous charge compression ignition) Wednesday at the company’s research and development center, the paper said. A product of advanced technologies and ingenuity, the engine promises as much as a 15 percent increase in fuel economy while reducing NOx gases considerably.

Uwe Grebe, GM’s executive director of powertrain advanced engineering, could not say when an HCCI engine would become production-ready, noting only that it would be in the next decade. But the process can “be applied to many engines, including four- , six- and eight-cylinder engines,” Grebe told the paper. (The Detroit News)
