Presentation Transcript

  1. Introduction • EPA standards for fuel economy and harmful emissions • Health and environmental effects of hydrocarbon fuel combustion • Idle reduction • Immediate savings after implementation • Reduced consumption of foreign oil

  2. Lesson 1: Introduction to Idle Reduction

  3. Objectives • Describe what idle reduction is • Explain the basic history of idle reduction strategies and technologies • Describe how implementing idle reduction strategies will benefit health and the environment • Explain the economic benefits associated with idle reduction • Describe what energy security is and how idle reduction affects it

  4. Definition of Idle Reduction • Petroleum and emissions reduction technologies and strategies • Idle = speed at which ICEs rotate under no throttle or load • Tachometer displays engine speed (600-1,000 rpm) • Smooth engine operation during acceleration from stop and adequate oil pressure

  5. Transportation and convenience idling • Technologies, policies, strategies to reduce engine idle time • Strategies and technologies to reduce both transportation and convenience idling Figure 1: The engine tachometer showing a vehicle’s idle speed. Source: NAFTC.

  6. Idling a vehicle may allow for the comforts of heat or A/C and the operation of accessories such as radios or other multimedia, but when your vehicle is idling, your fuel economy when not in motion is 0 mpg.

  7. Basic History of Idle Reduction • ICEs in use since the early 20th century • Old = mechanical carburetors/fuel pumping systems • New = electronic throttle, high pressure fuel system, electronic fuel injection • Idling vehicles produce no propulsion but still consume fuel and produce emissions

  8. Pre-heating, pre-cooling for comfort • Idling while waiting for traffic, etc. • Load from accessories • Long-haul trucks may idle up to 300 nights a year • Non-driving time requirements

  9. Policies for Idle Reduction • U.S. EPA emissions and CAFE fuel economy standards • More attention is being paid to emissions produced from idling • Federal tax exemptions for heavy-duty trucks • New vehicles and aftermarket products • Clean Cities program, SmartWay Transportation, Clean School Bus USA partnership, and others

  11. State enacted policies and idle limitations • Local and city government regulations • School bus emissions at idle • Amount of fuel used per idle time • Reduced idling = immediate fuel savings Figure 3: School bus at idle, consuming fuel and producing emissions. Source: EPA.

  12. Idling a car for one hour consumes about one gallon of fuel. Source: http://www.consumerenergycenter.org/myths/idling.html.

  13. Idle Reduction Today • Cleaner, healthier planet • Improved fuel efficiency and reduced emissions • Innovative technologies, specialized technicians • Technologies and strategies implemented by both manufacturers and consumers

  14. Consumer Idle Reduction Strategies • Any reduction in idle time can save fuel and reduce emissions • Idling during in-city driving • Avoiding congested areas • Limit idle time for convenience • Immediate fuel savings

  15. Manufacturer Idle Reduction • New technologies, improved fuel economy, and reduced emissions • Light-, medium-, and heavy-duty vehicle fuel savings • Idle shutoff functions, mild hybrid technologies • APUs for long haul trucks • TSE implementation Figure 4: Driver in a long haul truck utilizing a type of TSE.

  16. Truck idling uses approximately 3 billion gallons of fuel per year Approximately 1 billion gallons for overnight idling Roughly 2 billion gallons for workday idling Every hour a truck idles unnecessarily is equivalent to about 8 to 10 miles of on-road driving.

  17. Why Consider Idle Reduction? • Personal and environmental health • Financial and fuel economy improvements • Technologies manufacturing and service • Implementation by both consumers and fleets • Immediate reductions in fuel consumption and emissions

  18. Advantages of Idle Reduction • Reduced fuel consumption • Fewer vehicle emissions • Lower operating costs • Increased engine life • No-cost implementation

  19. Additional Points to Consider • Possible capital investment • Personal convenience may be compromised

  20. Benefits of Idle Reduction • Health and environmental benefits • Reduced fuel costs - economics • Reduced dependence on foreign oil – energy security

  21. Health Benefits • Combustion of fuels produces harmful emissions • Creation of PM • Respiratory and cardiovascular complications • Idle reduction reduces vehicle emissions

  22. Environmental Benefits • Emissions negatively affect the environment • GHG formation, climate change • Idle reduction = reduced emissions

  23. Economic Benefits • Excessive idling = unnecessary financial loss • Industry opportunity for implementation of idle reduction technologies • Reduced consumption = financial benefit for all drivers

  24. Energy Security Benefits • Reduced idling = reduced fuel consumption • Reduced fuel consumption = reduced reliance on foreign oil • Nearly half of all petroleum used in the U.S. is imported

  25. Upon completing this lesson, can you: • Describe what idle reduction is? • Explain the basic history of idle reduction strategies and technologies? • Describe how implementing idle reduction strategies will benefit health and the environment? • Explain the economic benefits associated with idle reduction? • Describe what energy security is and how idle reduction affects it?

  26. Test Your Knowledge • True or False: Engine speeds of idling engines under no load are typically 600-1,000 rotations per minute (rpm). • What does the acronym TSE stand for and how does it relate to idle reduction? • A passenger car that is idles for one hour consumes about ___ gallon(s) of fuel. • True or False: Vehicles that are idling while not moving have a fuel economy of 0 miles per gallon (MPG).

  27. Lesson 2: Idle Reduction Policies, Infrastructure, and Sustainability

  28. Objectives • Describe federal, state, and local policies on idle reduction • Explain how both manufacturers and consumers can implement idle reduction strategies • Explain the need for distribution of knowledge and possible infrastructure changes to assist in idle reduction • Describe how idle reduction relates to sustainability and cost efficiency

  29. Idle Reduction Policies • Reduced allowable emissions from vehicles • CAFE fuel economy standards for passenger cars and trucks • New goals implemented by the Obama administration • Fuel economy gains of more than 5% per year
