Using Biodiesel Fuel in Your Engine
RENEWABLE AND ALTERNATIVE ENERGY FACT SHEET Using Biodiesel Fuel in Your Engine Introduction Biodiesel is an engine fuel that is created by chemically reacting fatty acids and alcohol. Practically speaking, this usually means combining vegetable oil with methanol in the presence of a cata- lyst (usually sodium hydroxide). Biodiesel is much more suitable for use as an engine fuel than straight vegetable oil for a number of reasons, the most notable one being its lower viscosity. Many large and small producers have begun producing biodiesel, and the fuel can now be found in many parts of Pennsylvania and beyond either as “pure biodiesel” or a blended mixture with tradi- tional petroleum diesel (e.g., B5 is 5 percent biodiesel, 95 percent petroleum diesel). The process of making biodiesel is simple enough that farm- ers can consider producing biodiesel to meet their own needs by growing and harvesting an oil crop and converting it into biodiesel. In this way, farmers are able to “grow” their own fuel (see the Penn State Cooperative Extension publication Biodiesel Safety and Best Management Practices for Small-Scale Noncom- biodiesel fuel has less energy per unit volume than traditional mercial Production). There are many possible reasons to grow or diesel fuel. use biodiesel, including economics, support of local industry, and environmental considerations. • Fuel efficiency: fuel efficiency tends to be slightly lower when However, there is also a great deal of concern about the effect using biodiesel due to the lower energy content of the fuel. of biodiesel on engines. Many stories have been circulating about Typically, the drop-off is in the same range as the reduction in reduced performance, damage to key components, or even engine peak engine power (3–5 percent). -

Air Quality Impacts of Biodiesel in the United States
WHITE PAPER MARCH 2021 AIR QUALITY IMPACTS OF BIODIESEL IN THE UNITED STATES Jane O’Malley, Stephanie Searle www.theicct.org [email protected] twitter @theicct BEIJING | BERLIN | SAN FRANCISCO | SÃO PAULO | WASHINGTON ACKNOWLEDGMENTS This study was generously funded by the David and Lucile Packard Foundation and the Norwegian Agency for Development Cooperation. International Council on Clean Transportation 1500 K Street NW, Suite 650, Washington, DC 20005 [email protected] | www.theicct.org | @TheICCT © 2021 International Council on Clean Transportation EXECUTIVE SUMMARY Since the passage of the Clean Air Act in 1970, the U.S. Environmental Protection Agency (EPA) has enacted standards to reduce vehicle exhaust emissions. These standards set emission limits for pollutants that contribute to poor air quality and associated health risks, including nitrous oxide (NOx), hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM). Although the majority of the on-road vehicle fleet in the United States is fueled by gasoline, diesel combustion makes up an overwhelming share of vehicle air pollution emissions. Air pollution emissions can be affected by blending biodiesel, composed of fatty acid methyl ester (FAME), into diesel fuel. Biodiesel increases the efficiency of fuel combustion due to its high oxygen content and high cetane number. Studies have found that biodiesel combustion results in lower emissions of PM, CO, and HC, likely for this reason. However, studies have consistently found that biodiesel blending increases NOx formation. Industry analysts, academic researchers, and government regulators have conducted extensive study on the emissions impacts of biodiesel blending over the last thirty years. The EPA concluded in a 2002 report that, on the whole, biodiesel combustion does not worsen air quality compared to conventional diesel and reaffirmed that conclusion in a 2020 proposal and subsequent rulemaking. -

Evaluating Green Fleet Options
SUSTAINABILITY/CLIMATE CHANGE Evaluating Green Fleet Options Cities and counties throughout California are considering adopting policies and programs to “green” their fleets by purchasing fuel-efficient and alternative-fuel vehicles. While many agencies already have experience in this area, some local officials have questions regarding green fleet options. The Institute for Local Government (ILG) conducted a survey in 2010, Benefits of Green Fleets through its climate change program, that asked local officials what questions they Taking steps to make agency fleets greener has have regarding green fleet options. ILG other benefits in addition to potential fuel and used the survey results to develop cost savings and lessening dependence on information to help local officials foreign oil. Because transportation is the evaluate their options related to green largest generator of greenhouse gas emissions, fleets. The project was funded by AAA reducing fuel use helps to decrease such Northern California, Nevada and Utah. emissions. Defining the Terminology Fuel-efficient vehicles get better than average gas mileage, though they may still run on petroleum-based fuels, such as gasoline and diesel or a combination of petroleum-based fuel and another power source. Alternative-fuel vehicles run on non-petroleum-based power. Some of these alternative fuels are produced domestically, reducing dependence on imported oil, and some are from renewable sources. Alternative fuels typically cost less than petroleum-based fuel and produce less pollution than gasoline or diesel. Flexible-fuel vehicles, another type of alternative-fuel vehicle, can run on gasoline or a gasoline-ethanol blend of up to 85 percent ethanol, also known as E85. -

Tomorrow’s Vehicles: An Overview of Vehicle Sales and Fuel Consumption Through 2025 1 Executive Summary Low oil prices resulting from a sustained global oversupply are likely to rise, as production must eventually subside to balance demand. The balancing process will likely play out for some time as new vehicle fuel efficiency improvements and alternative fuel vehicles (AFVs) make advancements to road transportation, oil’s largest market, limiting price gains from production constraints. Though low oil prices place downward pressure on alter- native fuels and fuel-efficient vehicles, growth of particular technologies in various vehicle segments will not likely abate. Both governments and consumers in major light duty and commercial vehicle markets have shown particular interest in electricity and natural gas, and automakers are responding accordingly. -

Analysis of Design of Pure Ethanol Engines
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Federation ResearchOnline 2010-01-1453 ANALYSIS OF DESIGN OF PURE ETHANOL ENGINES Alberto Boretti University of Ballarat, Ballarat, Victoria, Australia Copyright © 2010 SAE International ABSTRACT Ethanol, unlike petroleum, is a renewable resource that can be produced from agricultural feed stocks. Ethanol fuel is widely used by flex-fuel light vehicles in Brazil and as oxygenate to gasoline in the United States. Ethanol can be blended with gasoline in varying quantities up to pure ethanol (E100), and most modern gasoline engines well operate with mixtures of 10% ethanol (E10). E100 consumption in an engine is higher than for gasoline since the energy per unit volume of ethanol is lower than for gasoline. The higher octane number of ethanol may possibly allow increased power output and better fuel economy of pure ethanol engines vs. flexi- fuel engines. High compression ratio ethanol only vehicles possibly will have fuel efficiency equal to or greater than current gasoline engines. The paper explores the impact some advanced technologies, namely downsizing, turbo charging, liquid charge cooling, high pressure direct injection, variable valve actuation may have on performance and emission of a pure ethanol engine. Results of simulations are described in details providing guidelines for development of new dedicated engines. INTRODUCTION Ethanol is an alternative fuel resulting in less greenhouse gas (GHG) emissions than gasoline [1]. The key environmental benefit of ethanol is that, unlike gasoline and diesel, its consumption does not significantly raise atmospheric levels of CO2. This is because the CO2 which is released during the burning of the fuel is counter- balanced by that which is removed from the environment by photosynthesis when growing crops and trees for ethanol production. -
HOW to UNDERSTAND ELECTRIC CAR FUEL EFFICIENCY and FUEL CONSUMPTION (Or, What the Heck Is Mpge)
HOW TO UNDERSTAND ELECTRIC CAR FUEL EFFICIENCY and FUEL CONSUMPTION (or, what the heck is MPGe). Solarponics Energy Solutions 4700 El Camino Real, Atascadero, CA 93422 (805) 466-5595 www.solarponics.com [email protected] Ask anyone what kind of gas mileage their car gets, and they will probably know right off the top of their head. We’re obsessed with the gas mileage of our cars, in large part because of the high cost of gasoline. Gas mileage performance ranks as a top decision when deciding to buy a new car. But how do we determine the fuel costs of an electric vehicle? How do we really know the cost comparison to drive an electric vehicle 100 miles, vs. driving a gasoline vehicle 100 miles? What does MPGe mean? How are the stickers calculating annual fuel cost? How do the manufacturers calculate my five-year fuel savings over a new gasoline vehicle? The first thing I should point out is that the window sticker of an EV makes several assumptions. First, that energy rates are 12¢ per kWh, that gasoline costs $4.00 per gallon, and that a new fuel efficient gasoline vehicle gets 22 miles per gallon. I’ll explain the window sticker using these assumptions, and then compare that to real-life values. The electric vehicle MPGe, or Miles Per Gallon equivalent, represents the number of miles the vehicle can travel using the same energy content as gasoline. My EV window sticker states an MPGe of 99. This is also the maximum distance this vehicle can travel on a full charge.
