System Validation · ECOSAILCombining DPF, DOC and SCR on a Marine Diesel Test Bench
The 1,100 kW test bench treats particulates, hydrocarbons, carbon monoxide and nitrogen oxides through one coordinated aftertreatment chain.
Move From Single-pollutant Devices to a Chain
DPF captures particles, DOC oxidizes CO and HC, and SCR reduces NOx. Their order changes downstream temperature, composition and pressure loss.
Design Around Testing and Service
Temperature, differential-pressure and emissions points support repeated tests, while clear removal paths support filter cleaning, catalyst checks and sensor calibration.
Record Response Across 0–100% Load
Flow, temperature, pressure loss and pollutant composition change through the load range, so the complete chain must be validated at multiple operating points.
