EVALUATION OF EVAPORATIVE EMISSIONS FROM ONROAD MOTORCYCLES January 15, 2006
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
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
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
Inventory Development • Evaporative emissions testing will include the following tests: • Running loss test • Hot soak test • Diurnal test
Inventory Development (cont.) • Running loss tests will be conducted at 95°F with a radiant heat load of 931 W/m2 • 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
Control Technology Testing • Control technology testing for the purpose of setting a standard will be evaluated on OHRVs • Control technologies will include: • Low permeation fuel tank and fuel line • Carbon canister • Fuel injection
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
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
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
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
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
