Main features: good economy, improved combustion at low load due to use of “HALLO” technology (smooth fuel consumption curve, quite low consumption even at part |
|
load), good startability and speed-up performance, high reliability, low noise and long service life (first overhaul interval up to 24000h), convenient to service. Based on |
|
TBD604B diesel engines, TBD620 diesel engines are uprated, and the crankcase structure is more proper, more robust, less deformation and can bear high explosion |
|
pressure. The two types of engines have no special requirement on fuel and can meet the requirement of IMO Nox emission. |
