Why Alternative Fuels?

• Reduce toxic emissions • Eliminate support for oil based

politics• Eliminate environmental impact of

harvesting, transporting, and manufacturing gasoline

• Fossil Fuels are not sustainable

What is Biodiesel?

• Biodiesel is the name of a clean burning alternative fuel, produced from domestic, renewable resources. Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with little or no modifications. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics. (National Biodiesel Board)

How is Biodiesel made?

• Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil. The process leaves behind two products -- methyl esters (the chemical name for biodiesel) and glycerin, a valuable byproduct used in soaps and other products. (National Biodiesel Board)

Alternative Fuels

• Vegetable Oil– Biodiesel– Straight Vegetable Oil (SVO – also known as

Waste Vegetable Oil or WVO)• Electric

– Electric Vehicles (EV)– Electric Hybrid

• Propane• Ethanol• Hydrogen Fuel Cell• Air Car

Why Vegetable Oil?

• Plenty of new and used diesel vehicles are available today

• Primary fuel sources (biodiesel) are widely available on the West Coast

• Secondary fuel sources (petrodiesel) are available worldwide

• Parts manufacturers & repair mechanics are available worldwide

• Fuel production can be localized• When the fuel source expires, there is no

toxic end product (such as a battery)

Why Vegetable Oil?

• Energy Yield: The production of biodiesel yields 320% more energy than is used in manufacturing it (US Dept of Agriculture)

• Mileage: Diesels are very efficient engines (20-50% more efficient than gas)

• Emissions:

Reduced Emissions

Why choose Biodiesel over SVO?• Biodiesel is legal, SVO is not• Less car maintenance required• Less operational headaches• More consistent fuel sources• Backed by your engine’s warranty

The Diesel Experience

• How does a diesel engine work?• Characteristics of older diesel

vehicles• Today’s diesel engine

Rudolph Diesel

• Invented Diesel Engine in 1892 to run on Peanut Oil

• “The use of vegetable oils may seem insignificant today. But such oils may in the course of time be as important as petroleum and the coal tar products of present time.” – 1912

• (courtesy of the National Biodiesel Board)

Engines

• A gasoline engine intakes a mixture of gas and air, compresses it and ignites the mixture with a spark.

• A diesel engine takes in just air, compresses it and then injects fuel into the compressed air. The heat of the compressed air lights the fuel spontaneously.

Plugs

• Gas engines have spark plugs to ignite the air-fuel mixture.

• Diesel engines have glow plugs that help the diesel turnover in cold-start circumstances when the air-fuel charge cannot be brought up to combustion temperatures.

• A glow plug works like a heated wire and raises the air temperature inside the cylinder for cold-start, after which it turns off.

Engine Compression

• A gasoline engine compresses at a ratio of 8:1 to 12:1, while a diesel engine compresses at a ratio of 14:1 to as high as 25:1. The higher compression ratio of the diesel engine leads to better efficiency.

Diesel Fuel

• Diesel is heavier than gasoline.• Diesel is a better lubricant than gasoline.• Diesel evaporates much more slowly

than gasoline• Diesel’s boiling point is higher than

water.• Diesel fuel contains more energy per

gallon than gasoline. (155 x 106 joules vs. 132 x 106 joules)

Biodiesel• Biodiesel is non-toxic (does not contaminate

water or soil)• Biodiesel is more lubricious than petrodiesel

(B2 is 66% more lubricious than diesel)• Biodiesel is a solvent (rots rubber)• Biodiesel decomposes more quickly than

petrodiesel• Biodiesel gels at a higher temperature than

petrodiesel• Biodiesel has a higher flash point (260°-425° F

vs. 125 ° F)• Biodiesel can be mixed with petrodiesel at any

ratio

Characteristics of old diesels

• Noisy• Dirty• Smelly• No pick-up• Difficult to start in winter• Great mileage• Low maintenance• Last forever• Accountants love em for the overall cost

savings

Today’s Diesels• Turbo

– Increased pickup– Increased efficiency– Burn more particulates

• Electronic Fuel Injection– Increased pickup– Increased efficiency– Burn more particulates

• Quick Glow Plugs– Decreased waiting

time before cold-starting

– Increased the probability of successful starts

• Exhaust Enhancements– Particulate Traps– Oxidation Catalysts

• Better engine design– Quieter

Purchasing a Diesel Vehicle

• Considerations• Sources• Makes & Models

Considerations

• Type of fuel lines (before or after 1994)

• Type of fuel injector pump• Fuel Filter• Difficulty in starting• Oil Consumption• Availability of parts

Sources

• New Car Dealers• Web Sites

– ebay.com– virtualclassifieds.net– portland.craigslist.org– gobiodiesel.org– greaseworks.org

Makes & Models

• Older– VW – Rabbit, Truck, Vanagon, Jetta, Dasher– Mercedes – 240D, 260D, 300D, 300TD,

300SD– Ford & Chevy – Full Size & Panel Trucks– 1980s Small Truck – Datsun, Toyota, Isuzu,

Mitsubishi– Obscure – Volvo, Peugeot, BMW– Import – Toyota, Mercedes– School Buses - International

Makes & Models

• Newer– VW (TDI) – Jetta, Beetle, Passat– Mercedes – E320CDI– Large Trucks – Duramax (Chevy),

Cummins (Dodge), Detroit (Ford)– Freightliner Sprinter

Breaking in Biodiesel

• Install Biodiesel propaganda on bumper• Install a second in-line fuel filter• Get to know your engine (Track MPG)• Start with small portions of Biodiesel (B20)

and increase slowly• Change fuel filter(s) often for at least the

first 6 months• Change fuel lines from Rubber to Viton

(synthetic) lines between 5,000 and 30,000 miles

Breaking in Biodiesel

• Things to remember about Biodiesel– Biodiesel is a solvent– Biodiesel rots rubber– Biodiesel gels when it gets cold

• Things to remember about diesel engines– They like Biodiesel– They like Oil– They don’t like water– They don’t like dirt

What should you expect

• Power will diminish slightly• Fuel efficiency will diminish slightly• When fuel filters are getting filled up with

gunk, the engine will hesitate, starved for fuel– Biodiesel will clean the fuel tank kicking up

sediment that the fuel filter(s) will catch

• Rubber Fuel Lines will begin to rot• Fuel Injector Pump Seals may also begin to rot• MPGs will drop as you go over 55 mph• Weight gain due to increased cases of the

munchies

Maintaining your Biodiesel Vehicle• Check & drain water separator

regularly• Changing the Fuel Filter

– Bleed the lines of any air– Fill the filter with ATF (Automatic

Transmission Fluid)– Change gaskets and seals

• Change Oil Regularly• Use B50 in Cold Weather – lowers cold

filter plugging point from 30° F to 4° F

Other Uses for Biodiesel

• Watercraft• Home Heat• Electric Generators• Kiln

Oregon HB 3481• Passed the House and Senate Revenue Committee• Reinstates the renewable fuel standard -- the requirement that oil companies

blend biodiesel into diesel (2% by mid 2006; 5% by 2010) and ethanol into gasoline (10% by 2010), but only if a certain number of gallons of each of these fuels is produced in Oregon

• Allows a property tax exemption for ethanol, biofuel (including biodiesel) and verified fuel additive production facilities

• Allows biofuels and biomass plants, as well as equipment used to produce biofuels or grow crops for biofuels, to qualify for the Pollution Control Tax Credit (PCTC)

• Provides tax credits to the producers of biofuel raw materials • Creates a Clean School Bus Grant Fund, but provides no seed funding • Bans MTBE and several other gasoline additives • Extends eligibility for expediting energy facility siting to biodiesel plants and

cellulosic ethanol plants • Exhorts state government to use alternative fuels, but does not require biodiesel

use • Reduces the fuel tax on biodiesel purchased for use in lightweight vehicles and

farm equipment traveling on road • Includes several other policies to support renewable energy and sustainability

(requires 1% solar in construction of new government buildings, provides lottery bonds for renewable energy R&D, allows construction of renewable energy facilities on state lands, and extends the sunset date of the sustainability board)

Final Comments

• Buy Biodiesel. I’ve heard folks say they no longer carry it due to lack of demand.

• Buy fuel that meets the standards - World Energy produced out of Spec Fuel (Fairfax, CA)

• There’s a making biodiesel workshop on Sunday July 23rd at the Oregon Biodiesel Workshop in North Portland (Contact: http://www.oregonbiodieselworkshop.com/)
