Wisconsin Bus Sales on Propane Buses Wisconsin Bus Sales on Propane Buses Presentation Transcript

  • PROPANE AUTOGAS One of the best kept secrets in alternative fuels is right here in our own backyard.
  • 90% of the propane used in the US is produced in the US. 33% of the world supply is from Texas.
  •  Fuel costs up to 50% less than gas and 30% less than diesel.  Infrastructure cost drastically less than other alternative fuels.  Propane autogas burns clean and potentially reduces maintenance costs and extends engine life. Economical
  • 5 Ford 6.8L-3V Engine & 6R140 Transmission “A Relationship that Began Over 80 Years Ago”
  • 6 6.8L-3V Engine Background  The 6.8L-3V engine is produced in Windsor Ontario. • 2.1 million square feet • 1850 employees  The 6.8L engine was introduced in 1997. An upgraded version of the engine was introduced in 2005 with 3 valves per cylinder (2 intake, 1 exhaust).  The 6.8L engine is currently used in Super Duty trucks (F450 – F550), Econoline vans, strip chassis, motorhomes and commercial step vans. Over 1 million 6.8L engines have been produced since its introduction.  The engine was upgraded with premium valves, valve seats and a larger oil pump to meet Blue Bird’s needs.

  • Local Benefits of Propane Powered School Buses: 1. Lower Emissions: Studies show that more than 70% of ambient air pollution comes from diesel emissions alone. 1 2 Diesel particulates are dangerous because they are so tiny, and can lodge into the deepest areas of human lungs. Children, in particular, are susceptible because they breathe 50 percent more air per pound of body weight than adults. 3 a. Propane powered buses emit virtually zero particulate matter.4 In essence, this is a 100% decrease in unhealthy particulate emissions when compared to diesel school buses. b. By running propane powered buses, your district will reduce their local Carbon Dioxide Emissions by around 311,000 lbs per year. *Assume 15,000 miles per year on 35 buses. c. Propane is nontoxic, non-carcinogenic, and is not considered a greenhouse gas if purged. In the unlikely event of a propane leak or spill, (unlike gasoline and diesel) propane does not harm the environment and is not a groundwater contaminant. 2. Impact Energy Security and Local Economy: 98% percent of propane comes from North American production. The main sources for propane are Natural Gas (80%) and Crude Oil (20%). a. Propane currently contributes more than $554 million to the Wisconsin economy, and the industry employs more than 1,430 people in Wisconsin alone. 5 b. By operating propane powered buses, your district will replace imported diesel consumption with 116,000 gallons of domestically produced propane autogas per year. *Assume 15,000 miles per year on 35 buses. 3. Safe Transportation: Propane Tanks are made of ASME certified ductile carbon steel, whereas, gasoline and diesel tanks are made of a hardened blow molded plastic. a. Propane Tanks are 20 times more puncture resistant than gasoline and diesel tanks. b. Auto-ignition: Propane has a much higher auto-ignition temperature when compared to gasoline and diesel. This means the minimum temperature of a spark must be much higher in order for propane to combust, whereas gas and diesel can ignite with a relatively cool spark: Propane: 842° F / Diesel: 494° F / Gasoline: 530° F c. Flammability Range: The range of air to vapor in which propane will ignite is narrower than that required for gasoline or diesel. Ratios for air to fuel ignition (rich limit ÷ lean limit): Propane: 4.5:1 / Diesel: 12.5:1 / Gasoline: 5.5:1 1 Solomon, Gina M., et al. “No Breathing in the Aisles: Diesel Exhaust Inside School Buses.” National Resources Defense Council and the Coalition for Clean Air.
