Evaluation of the Turbodyne (Trade Mark) II Self-Cleaning Air Filtration System on a Known Military Engine

摘要

The concept of a new type of self-cleaning air filtration system was demonstrated and evaluated. The system acquired significant advantages in volume, performance and logistics considerations by placement of the self-cleaning stainless steel barrier filter downstream of the turbocharger. The pressurized air within the barrier filter was used to blow back and clean the filter medium. Adequate protection of the turbocharger compressor wheel from dust erosion was accomplished by the highly efficient inertial precleaner alone. The precleaner was shown to be effective even at low airflow rates and high dust loads; the overall system completed 200 hours of operation on a Cummins VTA-903 using a modified SAE J726 test cycle at zero visibility without developing excessive restriction.
