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


Small spark ignited engines ssie

Small Spark-Ignited Engines (SSIE)

  • Typical Applications:

    • Chainsaws

    • Backpack Blowers

    • Pressure Washers

    • Lawnmowers


Large spark ignited engines lsie

Large Spark-Ignited Engines (LSIE)

  • Typical Applications:

    • Turf Care

    • Forklifts

    • Generators

    • Tractors


Spark ignited marine engines sime

Spark-Ignited Marine Engines (SIME)

  • Typical Applications:

    • Personal Watercraft

    • Jet Boats

    • Sterndrive/Inboard

    • Outboards


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


Engine tampering

Engine Tampering


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

Adjustable ParametersTRM Evaluation

  • 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

OFSEC SectionResponsibilities

  • New Off-Road Spark-Ignited Engines/Equipment

    • Certification

    • Audit


Audit program

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
