objective
Objective

Inform stakeholders of major changes to updated draft proposal

3/3/2010

updates to draft proposal
Updates to Draft Proposal
  • Implementation Dates
    • Harmonize with U.S. EPA rule for ≤40HP beginning in MY2012
    • Harmonize with U.S. EPA rule for >40HP in MY2012 and MY2013
    • Set more stringent standards for >40 HP beginning in MY2014
  • ORVR
    • ORVR has been removed from the proposal
    • However, ARB proposal will require Phase II compatible fill deck plates

Draft Proposal – Key ElementsSummary Table - ≤40HP Design Requirements

Harmonized Design Based Standards (≤ 40 HP)

  • ARB Certification begins in MY2012
  • Can only certify by design

3/3/2010

draft proposal key elements options for certification for 40hp
Draft Proposal – Key ElementsOptions for Certification For >40HP

Proposed Spark-Ignition Marine Engine regulation has two methods of certification:

  • Design-Based – Requires low permeation components and standards for venting and marine engine performance
    • low permeation fuel hose
    • low permeation fuel tank
    • venting performance test
    • meet fuel injection definition or perform fuel injection performance test
  • Performance-Based Alternative – One standard applied to the complete evaporative system
    • Based on a 24-Hour Diurnal Test (California Summer Profile)
    • The standard will be based on E10
      • 90% California Phase 3 Reformulated Gasoline with 10% by volume ethanol (Phase 3 CERT)

draft proposal key elements design requirements fuel hose
Draft Proposal – Key ElementsDesign Requirements – Fuel Hose
  • Fuel Hose Permeation Standard
    • 5.0 grams/m2/day
  • Test Procedure
    • 40 CFR 1060.515
    • High Accuracy Option – SAE J1737
    • Test temperature
      • 40°C
    • Test fuel
      • E10 or CE10

3/3/2010

draft proposal key elements design requirements fuel tank
Draft Proposal – Key ElementsDesign Requirements – Fuel Tank
  • Fuel Tank Permeation Standard
    • 0.70 grams/m2/day
  • Test Procedure
    • 40 CFR 1060.520
    • Test temperature
      • 28°C
    • Test fuel
      • E10 or CE10

draft proposal key elements design requirements diurnal
Draft Proposal – Key ElementsDesign Requirements – Diurnal
  • Diurnal Performance Standard
    • 0.25 grams/gallons/day
  • Test Procedure
    • 40 CFR 1060.525
    • Test fuel
      • E10
  • Diurnal standard can be met with any technology
    • However, if a pressure relief valve is used, durability must be demonstrated

draft proposal key elements design requirements fuel tank10
Draft Proposal – Key ElementsDesign Requirements – Fuel Tank
  • ARB performed 40 CFR 1060.520 on a 33 gallon tank with a 1.5L canister

3/3/2010

draft proposal key elements design requirements fuel injection
Draft Proposal – Key ElementsDesign Requirements – Fuel Injection
  • Meet Fuel Injection Definition
    • “Fuel Injection is defined as any mechanical or electrical fuel system in which pressurized fuel is sprayed or injected into the intake system of an internal combustion engine.”

or

  • Perform Fuel Injection Performance Test
    • Standard
      • 0.2 grams/hour
    • Test Procedure
      • TP-1502
        • 3-hour Hot Soak @ 105F
      • Test fuel
        • E10

Design Based Standards (> 40 HP)

*Using a test fuel of either Phase 3 CERT fuel or CE 10 fuel.

**Using Phase 3 CERT fuel.

***Using Phase 3 CERT fuel or CE 10 fuel with a test temperature of 40° C. As an option for high accuracy

testing, manufacturers may use SAE J1737.

****ARB certification begins in MY 2012.
