Undersökning av EGR-system i singelcylinder-provcell – med fokus på ökad tillgänglig EGR-mängd

, 2018
Dagens förbränningsmotorer ställs inför allt högre krav på att minimera de miljöfarliga restprodukter som förbränningen av luft och bränsle ger upphov till. Efterbehandlingssystem har utvecklats i olika former för detta ändamål, där en utav dessa är EGR:

Composite dilution effect of exhaust gas recirculation and lean-burn on combustion and emissions of oxyhydrogen/bio-isopropanol/gasoline ternary fuel engine

Frontiers in Energy Research
The complementary utilization of oxyhydrogen and bio-isopropanol in carbon-neutral fuel engines can effectively enhance power output and combustion stability. However, oxyhydrogen blended combustion results in an increase in NOx emissions.
