• 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

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
Inventory Development

• Evaporative emissions testing will include the
  following tests
• Running loss test
• Hot soak test
• Diurnal test

6
Inventory Development (cont.)

• Running loss tests will be conducted at 95F with
  a radiant heat load of 931 W/m2
• The load profile will be a modified UDDS profile
• Hot soak will be conducted at 95F
• Diurnal emissions test will be conducted on the
  EPA 72F-96F diurnal temperature profile

7
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

8
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
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 Motorcycle Test Plan Comments
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
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
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
