FORECASTING OF OPERATING PARAMETERS OF A MEDIUM-SPEED DIESEL ENGINE WITH TWO-STAGE TURBOCHARGING SYSTEM
Abstract
A comparative computational analysis of the partameters of the boosted D200 diesel engine having an average brake effective pressure of 2.7 MPa with one-stage and two-stage turbocharging systems has been carried out. Turbochargers for the first and second stages of the turbocharging system were selected. The calculations were performed using the model of the diesel engine 4-stroke cycle developed at MADI. The fuel efficiency results are similar with both turbocharging systems. For the two-stage turbocharging system, higher values of boost pressure, excess air ratio and lower boost air temperature were obtained. There were prospects for further power augmentation of the diesel engine with the two-stage turbocharging system, while the diesel engine with the one-stage system practically could not have any more power.
