Comparison in engine performance Technology applied to the newly developed "EcoDiesel SAVETEN" 1 Staggered layout nozzle The use of the staggered layout nozzles provides sufficient area for nozzle holes despite of their smallness and improves available air rate. This enables both lower fuel consumption and reduced smoke generation. Staggered layout nozzle combustion system 2 Air flow motion Suction swirl Analysis result of swirl port   Promotion of mixing air and fuel 3 Increases in combustion work, suction and exhaust work Increases in combustion work due to constant pressure combustion Increases in suction and exhaust work due to improvement of pumping efficiency
