California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

In cooperation with a major European supplier, a new oil-lubricated common-rail pump had therefore been developed. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption. An electrically driven compressor for precise exhaust gas recirculation is also used.

Neste and Rolls-Royce partner to accelerate use of renewable diesel

Green Car Congress

Neste and Rolls-Royce have agreed to build a strategic partnership on accelerating the use of renewable diesel as a lower-emission solution for diesel engines. Both parties share a common vision of renewable fuels playing a key role in reducing greenhouse gas emissions in off-highway applications, such as construction and power generation.

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. CRC research programs are managed by five technical committees (Advanced/Vehicle/Fuel/Lubricants, Atmospheric Impacts, Emissions, Performance, and Aviation.). Background.

University of Wisconsin Researchers Investigating Dual-Fuel (Gasoline and Diesel) Partially Premixed Combustion for High-Efficiency, Ultra-Low Emission Combustion; 53% Thermal Efficiency

Green Car Congress

Emissions under the dual-fuel concept, at 11 bar IMEP. Low temperature combustion (LTC) strategies (MK, PCCI, HCCI) are one way researchers are looking to reduce engine-out emissions while maintaining high engine efficiency.
