This Executive Order applies to 1991 through 2002 model—year 4—stroke heavy—duty diesel engines originally certified to meet a particulate matter emission standard of 0.10 grams per brake—horsepower—hour or lower. This Executive Order is only valid provided the engines meet the following operating conditions: (1) the engine exhaust temperature is greater than or equal to 260 degrees Celsius for 40 to 50 percent of the typical duty cycle, (2) the NOx to PM ratio is at least 8, and (3) the engine is operated using diesel with a maximum sulfur content of 50 parts per million by weight. This Executive Order is based on emission tests conducted by Johnson Matthey with the esns CRT Particulate Filter. Testing showed that the CRT Particulate Filter does not adversely affect the exhaust emissions of the test engines. The same emissions impact is expected when the CRT Particulate Filter is installed on heavy—duty vehicles equipped with any of the engines listed above. |

«27. This Executive Order is valid provided that installation instructions for the CRT Particulate Filter do not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer. Changes made to the design or operating conditions of the CRT Particulate Filter, as exempt by the ARB, which adversely affect the performance of the vehicle‘s pollution control system, shall invalidate this Executive Order.
