Improvement of Fuel Economy by VTI (Variable Turbine Inlet)

　Merit　

　Fuel efficiency improvement approx. 3% from conventional models.
    (In case of MET66MA)

　Applicable Type　

　MET-MBtype :flame size 48/53/60
　MET-MA type : flame size 53/60/66
　MET-SEII type: flame size 71

　Solution　

　nstallavariableturbineinlet(VTI) on theturbine side of the turbocharger.　
　*This modification also implies a change of turbocharger specification

　Feature　　

　Modification with butterfly valve/ special casing & nozzle enables to achieve turbine capacity
　that is suitable for partial-load operation,
    and optimize turbocharger efficiency at the operational point.

　Delivery Schedule　　

　Parts :Seven (7) Months
　Work period : about four (4) days
　*Piping of “control air for valve”, valve control sequence, etc. are the engine builder’s scope of service/ work.

　Quotation　　

　Please kindly requested to contact us for business inquiry.

　Current situation　　

　Many vessels are currently under slow speed operation, and main engine is also operating at partial load.
　Therefore, there is a room for improvement by applying VTI additional installation.

　Different parts　　

[ Remark ]Regulator /Signal converter/Distributor , Programing of software, or governor controller, etc.
　　　　 are scope of engine builder.
