The ARB has verified the Extengine Transport Systems Advanced Diesel Emission Control (ADEC) system for 1991 to 1995 model year off-road Cummins 5.9-liter diesel engines from 150 to 200 horsepower, which are used in excavators, dozers, and loaders, all with rubber tires, and utility tractor rigs operating on standard CARB or ultra low sulfur diesel fuel. The ADEC system employs a diesel oxidation catalyst, selective catalytic reduction catalyst, and ammonia slip catalyst to achieve a 25 percent reduction in particulate matter emissions, qualifying it for a Level 1 verification. The system also achieves an 80 percent reduction in NOx emissions. Specific conditions for which the ADEC system has been approved may be found in the Executive Order posted below.
