The video cassette recorder system can readjust the air compression proportion in the engine burning chamber to an ideal equilibrium according to engine power and also LNG gas buildings. This ideal modification will certainly enhance gas effectiveness throughout procedure by regarding 3% in LNG gas setting and also regarding 6% in diesel oil setting.
The system is additionally anticipated to play an essential function in decreasing GHG exhausts from existing ships and also boosting engine effectiveness when decarbonized gas are presented.
