UN ECE R24 — Diesel Engine Visible Pollutants · 03 / S11

Use 03 series · Supplement 11 for a new R24 application. Distinguish engine approval, installation of an approved engine and approval of the complete vehicle.

• Covers visible exhaust smoke from diesel engines used in L, M and N vehicles.
• R49 approval to the 06 or a later series, R83 approval to the 06 or a later series, or R154 approval is equivalent for visible emissions; R24’s additional requirements still apply.

Check your existing engine and vehicle approvals first. When using equivalence, include the R24 measurement and marking requirements.

The latest level is 03 series · Supplement 11, effective from 15 June 2024. This amendment does not impose a new expiry date on all existing approvals.

• It updates test fuels, smoke measurement in production checks and engine-power acceptance tolerances.
• It sets no universal sales or registration deadline for all vehicles because of this amendment.

Prepare new tests and applications to the updated fuel and measurement requirements.

Supplement 11 does not automatically invalidate your existing approval. Notify the granting authority if you modify the engine or vehicle; that authority decides whether further testing is needed.

• Engine, exhaust or transmission changes may affect the approved type and test results.
• A production engine is checked against the approval value plus 0.5 m⁻¹ and the stated test conditions.

Provide the changed-part information and existing test report. Use Supplement 11 fuel requirements if additional testing is requested.
