Influence of Turbocharger Characteristics on Supply of Air for High Speed Diesel Engines 660133

Development of turbochargers with more favorable basis characteristics has significantly improved turbocharging at part speed and part load. Consequently, the engine air flow requirements for these operations can be met with less over-supercharging at rated power.
As engine bmep ratings are increased, the engine as well as the turbocharger and controls must be made more compatible, to limit excessive boost pressure in non-aftercooled engines and to avoid negative pressure differentials in after-cooled engines.
