Diesel Engine System Optimization Strategy
Compression ratio (≈16) optimized (Trade-off: CRS 2200-2500 bar, in future up to 3000 bar for
Fuel consumption/HC,CO) CO2 highest spec. power (PC Top) or part load BSFC
optimization (with reduced HFR) CO2
Air system and turbocharger transient CO2
optimized improved TC efficiency @ part load
optimized, Digital Rate shaping (DRS) for NVH and Fuel
Consumption reduction CO2
HP- and LP-EGR system (flexible fraction) CO2
+ efficient EGR cooling Reduced HC critical nozzle volume
SCR based NOx Aftertreatment to
achieve Euro 6 + RDE depending on EU
RDE and US Requirements CO2
Additional heat up measures (if required)
HP-/LP-EGR: High/low pressure exhaust gas recirculation; TC: Turbo charger; CRS: Common rail system; HFR: Hydraulic flow rate; NSC: NOx storage catalyst; SCR: Selective
catalytic reduction
Holistic system optimization approach required to fulfill future norms
