1. 1 EVALUATION OF EVAPORATIVE EMISSIONS FROM ONROAD MOTORCYCLES January 15, 2006

2. 2 Presentation Outline On Road Motorcycle Test Plan –Objective –Plan Overview –Inventory Development –Control Technology Testing –Quality Assurance/Quality Control –Next Steps Comments and Contact Information Onroad Motorcycles Models to Test ORVR Control Technology Test Results

3. 3 Objective The current onroad evaporative test procedure leaves a lot of uncontrolled emissions Current model shows ~12 TPD for 2025 ARB plans to –ARB is seeking additional reductions form this category –Evaluate emissions from carbureted and fuel-injected motorcycles under a more realistic test procedure –Simplify the certification process by aligning the on/off road motorcycles test procedure and standard

4. 4 Plan Overview New emissions factors will be developed to augment the current emissions factors Control technology testing from OHRVs is considered representative for onroad motorcycles

5. 5 Inventory Development Evaporative emissions testing will include the following tests: –Running loss test –Hot soak test –Diurnal test

6. 6 Inventory Development (cont.) Running loss tests will be conducted at 95°F with a radiant heat load of 931 W/m 2 The load profile will be a modified UDDS profile Hot soak will be conducted at 95°F Diurnal emissions test will be conducted on the EPA 72°F-96°F diurnal temperature profile

7. 7 Control Technology Testing Control technology testing for the purpose of setting a standard will be evaluated on OHRVs Control technologies will include: 1.Low permeation fuel tank and fuel line 2.Carbon canister 3.Fuel injection

8. 8 Quality Assurance/Quality Control Quality Assurance/Quality Control Testing will be conducted pursuant to 40 CFR, Part 86, Section 86.107-90 and 96, and the California Evaporative Emission Standards and Test Procedures for 1978-2000 Model Motor Vehicles ARB will evaluate all fuels used for testing to ensure they meet CARB and SAE specifications SHED temperature data is collected and evaluated on a minute by minute basis

9. 9 Next Steps for Rule Development (Tentative) Evaluate Emissions from Onroad Motorcycles –Winter 2009 – Summer 2009 Control Technology Evaluation –Current – Summer 2009 Development of Staff Proposal –Fall 2009 Board Hearing –2010

10. 10 Onroad Motorcycle Test Plan Comments

11. 11 Onroad Motorcycles Models to Test Draft list of possible onroad motorcycles ARB will test ARB is soliciting industry feedback ARB welcomes manufacturer supplied models where possible

12. 12 ORVR ARB is evaluating ORVR for Onroad motorcycles and OHRVs ARB is requesting industry input regarding: –Technical issues with implementing ORVR –Timeline to be able to implement ORVR

13. 13 Control Technology Test Results UNCORRECTED Control Technology Test Results for an OHRV* –Running Loss – 0.21** grams/23 minutes –Hot Soak – 0.37** grams/1.5 hours –Diurnal – 0.84** grams/24 hours 65-105ºF –Tip Test Results – 0 grams/test Total of 1.42** grams for a test cycle * OHRV tested was a 2006 Polaris sportsman 500 EFI ATV with 4.1 gallon tank. Test fuel was E10. Control technology included low perm. fuel system, simulated actively purged CC, and fuel injection. ** Corrected values will be very slightly lower
