DOE Co-Optima report identifies top ten bio-blendstocks for efficiency in boosted SI engines

Green Car Congress

A new Co-Optimization of Fuels & Engines (Co-Optima) report describes the top ten biofuel-derived blendstock candidates. These top candidates, when blended with petroleum and used in a boosted spark ignition (BSI) engine, will offer environmental benefits and boost energy efficiency all while being available at a competitive price.

32.5M hours of supercomputer time to aid GM, Ford engine projects with Oak Ridge Lab

Green Car Congress

The two projects are part of a larger multi-year DOE-funded project to develop and to apply innovative simulation strategies and tools to maximize benefits of predictive information from high performance computing (HPC) for internal combustion engines. Recently, the most popular SIDI gasoline injectors have been multi-hole type.

DKRW Advanced Fuels signs major off-take contract for 100% of coal-derived gasoline from Medicine Bow project

Green Car Congress

whereby Vitol would purchase 100% of the gasoline produced from MBFP’s industrial gasification and liquefaction facility located near. The cleaned syngas is conditioned, modified and converted to methanol, which is then converted to gasoline via the licensed ExxonMobil Research and Engineering methanol-to-gasoline (MTG) process.

CRC study finds some adverse results from use of mid-level ethanol blends in MY 2001-2009 engines; DOE and ethanol industry say study significantly flawed

Green Car Congress

The study claims mechanical damage and suggests degraded engine performance, emissions and durability on conventional vehicles from the use of E15 or E20 fuel. Growth Energy, an ethanol industry trade group, petitioned the EPA in March 2009 to raise the limit on ethanol in gasoline from 10 to 15 percent. Background. The CRC test.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

The green symbol and dashed arrow illustrate the large reductions in tailpipe VOC emission factors as precatalyst on-road gasoline vehicles were replaced by present-day vehicle fleets. Gasoline is stored in closed, hopefully airtight, containers and the VOCs in gasoline are burned for energy. You don’t do this with gasoline.
