This analysis examines the effect of this downturn in driving on gasoline consumption (both total and per capita), and places the consumption in 2020 in a historical context. The results show that gasoline consumption per capita in 2020 was on par with that 55 years ago. Total consumption. Total consumption (millions of gallons).
Knittel/Smith results for implied gasoline price effects from elimination of ethanol for 2010 using Du/Hayes model and pooled-sample estimates. Put simply, the empirical results merely reflect the fact that ethanol production increased during the sample period whereas the ratio of gasoline to crude oil prices decreased.

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). California currently limits the ethanol content of gasoline to 10 percent. SULEV30, ULEV50, ULEV70, and ULEV125).
The new version supersedes the J1711 standard originally published in March 1999. Also, the list of standard test procedures addressed in SAE J1711 has been expanded to cover all five major test cycle procedures (UDDS, HFEDS, US06, SC03, and Cold FTP) now being used to evaluate vehicle fuel economy. Earlier post.) Earlier post.)
A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines. of the data.

Fuel Efficiency Improvement Technologies for Conventional Stoichiometric Gasoline Direct Injection Multi-Cylinder Internal Combustion Engine.
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.
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. Accelerated testing is a standard practice in the automotive industry for producing faster results and higher expected performance from engines/vehicles. Background.
For the market launch in Europe, a gasoline and a diesel engine are available. Additional engines will follow in the course of the year, including a more powerful diesel and an entry-level gasoline engine, which works together with a 48 V mild-hybrid system.

In their study, published in the ACS journal Environmental Science & Technology they found that—compared to gasoline—the GHG savings from miscanthus-based ethanol ranged between 130% and 156% whereas that from switchgrass ranged between 97% and 135%. This difference was not statistically significant at any of the three locations.
A study by Ricardo for the Renewable Fuels Association (RFA) concludes that the adoption of E15 as the blend limit for standard US pump grades of gasoline rather than the current E10 should not adversely affect vehicles manufactured between 1994 and 2000 in terms of their performance and durability based on normal specifications and usage profile.
As well as achieving significant emissions reductions based on continuous evolutionary advances of the TwinPower Turbo gasoline and diesel engines, future BMW core brand models will also benefit from the transfer of new electrified drive technology (BMW eDrive) developed by the BMW i sub-brand. BMW eDrive. seconds, EU fuel consumption of 2.1
Among their findings is that an increased ethanol fraction in gasoline could help reduce PM mass and black carbon (BC) from gasoline direct injection engines (GDI). In the next decade, higher ethanol and lower aromatic content in gasoline may become more common due to the renewable fuels standard (RFS). Karavalakis et al.
This statistic increases to two-thirds of all new registrations if the data are restricted to passenger cars, according to Bosch. The introduction of the China 4 emission standards on 1 July 2013 imposes even more stringent requirements for commercial vehicles. Brazil: no diesel in passenger cars.

Test fluids, such as those suggested by SAE publication J1681, do not meet fuel quality standards and were not intended for comparison of the effects of different fuels because the effects of the aggressive test fluids relative to commercial fuels are unknown. The NREL report distinguishes between test fuels and test fluids.
Using statistical methods, the scientists infer emissions from these data within a radius of about one kilometer of the measurement location. Generally, different combustion and exhaust treatment characteristics result in significantly higher NO x /CO 2 emission ratios for diesel powered cars than for gasoline. —Thomas Karl.

These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought. A number of cities and outlying areas in the United States, however, remain out of compliance with EPA standards for ozone, which the agency made more stringent in 2015. —Zhe Jiang, lead author.
While traditional combustion vehicles remain the dominant option for American consumers, battery electric and standard hybrids both eclipse annual PHEV deliveries. By contrast, standard hybrids lacking a charging port were said to be 10.7 percent with battery only models representing 9.4 On paper, it makes a ton of sense.
All new plug-in-hybrids by Audi use a turbo-charged gasoline engine with direct injection that works together with an electric motor that is integrated in the transmission. Together with the electric motor that is integrated in the dual clutch transmission, a gasoline engine ensures that there is ample output and torque.
Although the starch-to-ethanol pathway is similar to that used for corn ethanol, based upon initial calculations from Drexel University, OBE’s winter barley ethanol has the potential to meet the criteria of an Advanced Biofuel as defined by the Renewable Fuel Standard-2 (RFS-2) and the Energy Independence and Security Act of 2007 (EISA 2007).

This requires simple, easy-to-understand terms without jargon, and that leverage consumer’s existing reference point of the gasoline refueling experience. For one, clarity and consistency is critical for sharing statistics and making comparisons. Time Is Now For The EV Industry To Have Standardize Terms Like Charging Station.
While studies show that 30% of newer drivers aged 18-25 plan to buy an EV next, the overwhelming majority (58%) in the US still plan to stick with gasoline. However, market competition, falling battery prices and government incentives are pushing the cost of EVs to parity with gasoline. older) drivers away from gas.
Lower-line Lightnings use the 12-inch horizontal display from high-end gasoline F-150s. All-wheel drive is standard on all versions of the Lightning today.) Still, it’s a use for EVs that gasoline trucks can’t duplicate, one that justifiably seized public attention. Top trims upgrade to a portrait-style 15.5-inch
