Dinex Innovation Insights: Dinex Solutions for H 2 Engines All You Need From Turbo To Tailpipe Why Choose Dinex Solutions for H 2 Engines? Dinex H 2 engine aftertreatment solutions (ATS) to reach near-zero tailpipe emissions Benefits using Dinex hydrogen technology solutions  Near-zero tailpipe emissions  Innovated for heavy duty  Cost optimisation On-road: Euro 7, EPA27, BS 7 Off-road: Stage VI, Tier 5, Trem V, CEV V Also compatible with near-zero emission applications Benefits of a hydrogen engine  Long range  Fast refilling Hydrogen Combustion Engines (H 2 ICE) are pivotal for decarbonizing heavy-duty tasks due to hydrogen’s carbon-free nature and ICE’s reliability and cost-effectiveness. Addressing pollutant emissions, particularly NO X , presents technical hurdles requiring aftertreatment solutions. Therefore, Dinex ATS solutions are essential for advancing the Hydrogen economy. NO X Storage Catalyst (NSC): • Stores NOX in cold start (100 – 150 °C) and release 150 °C • Increases NO 2 /NO X ratio to enhance NO X reduction efficiency of the SCR • NO X buffering effect reduces high NOx peaks during engine operation window OR H 2 Oxicat: • Oxidation catalyst for H 2 with low N 2 O formation • Increases NO 2 /NO X ratio to enhance NO X reduction efficiency of the SCR • H 2 Light off < 110°C DEF dosing and mixing: • Proven technology from diesel ATS • H 2 -injection can be accommodated • Heated dosing possible Vanadate SCR: • High DeNOX in operation window 180 – 400°C • Tolerant to high H 2 O content of 20–30% in the exhaust gas • Very low secondary emissions Canning: • Material selection compatible with exhaust gas composition of a hydrogen engine ENGINE TEST RESULTS With a combination of NSC + SCR, overall tailpipe emissions below 10mg/kWh are possible including cold start conditions. SCR volume can be decreased up to 50 % compared to Diesel SCR catalysts. Our Expertise.Your Advantage
