Validated methodology for rapid ash accumulation

An easy procedure was defined for rapid ash accumulation with the main objective to save expensive time on engine test-benches for investigations on ashes for R&D based on a dosage of additive in fuel and motor oil. A time-lapse factor of about 5 can be reached by adding ash-forming substances to fuel and oil compared to normal operation. The procedure is usable for small filters but not for large filters because it would need weeks to fill a filter with ashes.

To have a more effective ash accumulation method PUREM has purchased an ash generator outside the COMET-project. This ash generator is located between engine and filter and reaches a time-lapse factor of 30 - 100.
