EIA: US gasoline’s average energy content per gallon declined ~3% from 1993-2013 due to increasing ethanol fraction

Green Car Congress

The US Energy Information Administration (EIA) has adjusted its estimates of the energy content of retail motor gasoline in its Monthly Energy Review (MER) to reflect its changing composition. As a result, EIA’s estimate of motor gasoline’s average energy content per gallon has declined by about 3% over this 20-year period.

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

Fuel-cycle SO 2 emissions of EVs compared to those of gasoline ICEVs and HEVs in China, current (left) and future (right). The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.

Researchers say fuel market rebound effect can result in increased GHG emissions under RFS2; suggest taxes over mandates

Green Car Congress

A growing number of studies on the effects of biofuel production on domestic and international fuel markets have concluded that biofuel production results in only a partial displacement of gasoline on an energy-equivalent basis—thereby increasing global energy use. for its analysis.

Cleaner fuels have replaced more than 3B gallons of diesel under California Low Carbon Fuel Standard

Green Car Congress

New 2018 data from the California Air Resources Board (CARB) indicates that the state’s Low Carbon Fuel Standard (LCFS) continues to drive production of a growing volume of cleaner transportation fuels for California consumers. Those clean fuels also reduced emissions of toxic pollutants as well as those that cause smog.

KS Kolbenschmidt introducing 5th generation LITEKS piston system for improved fuel savings through friction reduction

Green Car Congress

KS Kolbenschmidt has developed its LITEKS concept for particularly low-friction piston systems installed in highly loaded gasoline engines. In order to achieve the defined piston friction targets for the latest product generation, numerous elasto-hydrodynamic multi-body simulations were carried out from the beginning of the development phase.

Peking University team develops method for modeling historical global black carbon emissions from motor vehicles with reduced uncertainty

Green Car Congress

Geographical distributions of global BC emissions from motor vehicles in 1976 (A) and 2006 (B). Country-based mean values are shown for 1976 and 1° × 1° resolution was used for 2006. Researchers at Peking University have developed a new methodology to model black carbon (BC) emissions from diesel and gasoline motor vehicles.
