State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—535—4 Relating to Exemptions under Section 27156 of the Vehicle Code Cleaire Advanced Emission Controls Longview System Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of the Vehicle Code; and Pursuant to the authority vestedin the undersigned by Sections 39515 and 39516 of the Healthand Safety Code and Executive Order G—02—003; IT IS ORDERED AND RESOLVED: That installation of the Longview System, manufactured by Cleaire Advanced Emission Controls of 14775 Wicks Boulevard, San Leandro, California 94577, has been found not to reduce the effectiveness of the applicable vehicle pollution control system, and therefore, the Longview System is exempt from the prohibitions in Section 27156 of the Vehicle Code for installation on heavy—duty on—road vehicles equipped with the following diesel engines: Model—Year Make Model 1994—1997 Cummins M11 1994—1997 International (formerly Navistar) DT466 This exemption is only valid provided the engines meet the following operating conditions: {1) the engine exhaust temperature is greater than 260 degrees Celsius for at least 25 percent of the typical duty cycle and (2) the engine is operated using either standard California diesel with a maximum sulfur content of 500 parts per million by weight (ppmw) or ultra low sulfur diesel with a maximum sulfur content of 15 ppmw. The Longview System consists of a lean NOx catalyst, secondary fuel injection system, electronic controller, control sensors, and a catalyzed passive diesel particulate filter. The fuel injection system includes a fue! pump, injector, injector block, static mixer, and a pressure regulator. The sensors include a manifold absolute pressure sensor, engine speed sensor, two exhaust temperature sensors, and an engine backpressure sensor. The fuel injection control algorithms for both standard California diesel and ultra low sulfur diesel are identical. The major components of the Longview System are identified in Attachment A. This exemption is based on emission testing and engineering evaluation conducted by Cleaire Advanced Emission Controls. It was determined that the Longview System would not have any adverse impact on exhaust emissions. This Executive Orderis valid provided that installation instructions for the Longview System — do not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer.
