ofsec section what do we certify
OFSEC SectionWhat do we Certify?
  • Off-Road Spark-Ignited Engines/Equipment
    • Small Engines (≤ 19 kW)
    • Large Engines (> 19 kW)
    • Recreational Marine
  • Exhaust Emissions(g/kW-hr)
    • HC+NOx, CO, PM
  • Evaporative Emissions
    • Diurnal, Running Loss, Fuel Cap

spark ignited engine certification
Spark-Ignited Engine Certification
  • How do you know if new engines/equipment will meet California’s emission standards?
  • CERTIFY THEM!
    • Does it meet emissions standards?
      • Label
      • Warranty
      • Tamper-resistance
    • Will it be durable?
  • Certification is required before products can be legally sold in California

Engine Tampering:

How Certification

Addresses this Problem

engine tampering how certification addresses this problem
Engine TamperingHow Certification addresses this problem
  • Tampering with engines prevalent
  • Consumers tend to tamper with engines because:
    • Simple to adjust with ordinary tools
    • Perceived performance benefits
    • Human nature!
  • Emission impacts of tampering significant
  • To remedy this problem, California regulations require adjustable parameters to be tamper-resistant
adjustable parameters
Adjustable Parameters
  • Definition: any device, system, or element of design which is physically capable of being adjusted, and which, if adjusted, may affect emissions or engine performance
  • Example: carburetor air/fuel mixture screws (idle & WOT)
  • Two design types:
    • Limited Range of Adjustment
    • Tamper Resistance Method (TRM)
adjustable parameters equipped with range of adjustment
Adjustable ParametersEquipped with Range of Adjustment

L-screw limited to 315o

  • Example: carburetor air/fuel mixture screw (rich to lean setting)
  • Engine must meet emission standards at any setting
  • Manufacturer may be required to test at any point in the range of adjustment (rich/lean)

H-screw

limited to 270o

adjustable parameters equipped with tamper resistance method
Adjustable ParametersEquipped with Tamper Resistance Method
  • Tamper resistant, not tamper proof

(Common sense approach)

  • 40 CFR 90.112b: Not considered adjustable if:
    • permanently sealed by manufacturer
    • not normally accessible using ordinary tools
  • Examples of tamper resistance methods:
    • Limiter Caps
    • Breakoff Screws
    • Metal Plugs
    • Adjustable using special tools
    • Inaccessible due to parameter recessed in engine housing

  • Staff tests tamper resistance as a part of certification
    • Commonly available tools,

e.g. pliers, screwdrivers, hammer

    • Testing done in less than 30 minutes
    • No damage to carburetor or engine
    • At least two staff participate

Audit Program
  • How do you make sure that the manufacturers produce engines/equipment like the ones they certified?
  • AUDIT THEM!
    • New Engine (Title 13) Audit testing at ARB or manufacturer’s facilities
    • Production line reports
    • Assembly-line inspections
title 13 audit new engine compliance testing
Title 13 AuditNew Engine Compliance Testing
  • Staff visits manufacturer facilities to verify compliance with emission standards and regulations.
    • On-site emission testing
    • Assembly-line inspection
    • Verify part numbers, label, warranty, and tamper resistance method
