Rudolf DieselRudolf Diesel

Rudolf Diesel constructed the first diesel engine in 1897

This led to an 1898 patent #608,845 for the “internal combustion engine”. Rudolf proved that a theoretical 75.6% efficiency engine was possible.

In 1912 he stated: “The diesel engine can be fed with vegetable oils and would help considerably in the development of agriculture of the countries which use it” and that “The use of vegetable oils for engine fuels may seem insignificant today. But such oils may become in course of time as important as petroleum and the coal tar products of the present time.”

U.S. Trade DeficitU.S. Trade Deficit

• The U.S. imports more goods from abroad such as oil than it exports. In 1975, the U.S. exported $12.4 million more that it imported.

• By 2009, the U.S. trade deficit grew to $380.7 billion.• The Treasury Department estimates that our National

debt is soaring and our debt to China alone is approximately $889 billion. That is more than $10,000 in debt for the average American working family.

U.S. Oil DependencyU.S. Oil Dependency

• The U.S. has 5% of the world population, but consumes 25% of the worlds energy supply.

• The U.S. currently uses 20-million barrels of oil a day.

U.S. Oil ProductionU.S. Oil Production• In 1950 the U.S. was the worlds top oil producer.• Until the 1950s the United States produced nearly all the

petroleum it needed. But by the end of the decade the gap between production and consumption began to widen and imported petroleum became a major component of the U.S. petroleum supply. Starting in 1994, the Nation began importing more petroleum than it produced.

U.S. Oil ProductionU.S. Oil Production

• Currently the U.S. produces 8-9 million barrels of oil a day, which is less than half of our daily consumption.

• Canada and Mexico supply a portion of the shortfall, however, the remaining supply is imported from countries that do not like the U.S. very much.

• Today almost 60% of the U.S. oil demand is imported. This translates to the largest transfer of wealth from the U.S. to other countries in world history.

• This equates to $900-million a day being sent by the U.S. to oil exporting countries.

ODOT FUEL USAGEODOT FUEL USAGE

• ODOT currently uses approximately 2-million gallons of diesel, 90,000 gallons of 100% bio-diesel, and 1.3-million gallons of unleaded fuel annually.

• Ultra low sulfur diesel emits 99.4 grams of C02 per gallon.

• B-20 emits 86.5 grams of C02 per gallon, which is approximately a 13% CO2 emission reduction.

• Feed stock for Biodiesel is produced on farms in Montana, Idaho, Washington, and Oregon. No products are imported from foreign countries.

IDLE REDUCTIONIDLE REDUCTION• On average, an ODOT diesel engine consumes one gallon of

fuel per idle hour.• ODOT's diesel fleet idles 30 - 40% of its life (currently 37%).• Statistics show that idling for more than 10 seconds uses more

fuel than is required to restart the engine.• Documented wear statistics show the break even point between

wear and fuel savings is at 30 seconds of idle time.• Industry states warm-up time for a diesel engine is 30 seconds

to allow oil circulation, then slow speeds until engine reaches operating temperature.

• Excessive idling causes increased engine maintenance. Manufacturers advise to limit idling between 3-5 minutes as fuel is not completely burned causing build-up and engine wear.

• California suggests for every 2 minutes of idle time you can travel 1 mile for the same amount of fuel.

IDLE REDUCTIONIDLE REDUCTION• ODOT Fleet is installing engine coolant cab heaters in all

new 10 yd, 5 yd and 1 ton trucks. These heaters work from drawing heat from the engines coolant system after the engine has been shut off. This devise allows operators to shut the engines off between shifts and during lunch and breaks while the devises still provide heat and prevents freeze up.

• ODOT Fleet is replacing incandescent and halogen lamps in all new and some older 10, 5, and 1-ton trucks. This allows the battery to power lights for an extended period without the engine running.

• We are replacing VMS signs with new LED full matrix VMS’s , which extends the battery operating time without the engine running.

IDLE REDUCTIONIDLE REDUCTION• Installing low battery warning systems that will sound an alarm or

start the engine before the battery reaches a point where it won't start the engine in all new and retrofitting some older 10, 5, and 1 ton trucks. 

• Test results showed:

Truck with gas engine, one battery. Test started at 8:05 a.m. with engine off, state radio, LED warning lights, variable message sign, and engine cab heater running. Auxiliary equipment ran a total of 5 hours and 40 minutes before alarm sounded at 1:40 p.m. Truck started right up, idled for 15 minutes to recharge battery and shut itself off. All devices ran another hour and 35 minutes until the end of the meeting.  Total operation with single battery was 7 hours 35 minutes with 15 minutes idle time.

IDLE REDUCTIONIDLE REDUCTION

• Based on 30% idle time the average ODOT operator spends approx 52 hours a month idling.  This costs ODOT $125 a month in Diesel and generates 1,152 lbs of CO2 for each vehicle.

IDLE REDUCTIONIDLE REDUCTION

• One percent reduction in idle time saves $16,000 a year in fuel, and 146K lbs of CO2, equal to each driver turning engine off 5 minutes a day.

• Five percent reduction in idle time saves ODOT $80,000 a year in fuel, and 730,000 lbs. of C02, equal to each driver turning off engine only 25 minutes a day.

• For example: Shutting off the engine for both breaks or on a lunch period will accomplish a 5% idle reduction.
