This issue of this Marine Installation Manual (MIM) contains all data and information for Wrtsil 58RT-flex58T-D two-stroke marine diesel engines which were published in the MIM issue August 2010 and is amended with data for EO versions. This manual covers the Wrtsil RT-flex58T-D engines with the following MCR: Power per cylinder Speed Mean effective pressure at R1 2260 kW 105 rpm 20.2 bar 3075 bhp

All data are related to engines compliant with IMO-2000 regulations Tier II and refer to cost-optimised and/or efficiency-optimised versions. Cost-optimised engines (CO) are fitted either with ABB TPL-B or MHI MET MA turbochargers; Efficiency-optimised engines (EO) are fitted either with ABB A100-L or MHI MET MB turbochargers. Compared to the cost-optimised version, the efficiency-optimised version has no additional or particular requirements for the engine installation. The engine performance data (rating R1) refer to winGTD version 3.0. The engine performance data (BSFC, BSEF and tEaT) and other data can be obtained from the winGTD-program, which can be downloaded from our Licensee Portal. This Marine Installation Manual is complete within itself, no additional documentation is necessary.

Table A1 Primary engine data of Wrtsil RT-flex58T-D

All brake specific fuel consumptions (BSFC) are quoted for fuel of lower calorific value 42.7 MJ/kg (10200 kcal/kg). All other reference conditions refer to ISO standard (ISO 3046-1). The figures for BSFC are given with a tolerance of +5 %. The values of power in kilowatt (kW) and fuel con sumption in g/kWh are the standard figures, and discrepancies occur between these and the corre sponding brake horsepower (bhp) values owing to the rounding of numbers.

To determine the power and BSFC figures accu rately in bhp and g/bhph respectively, the standard kW-based figures have to be converted by factor 1.36.

Tuning options A2.2 Low-Load Tuning (LLT)

With the introduction of the Wrtsil RT-flex en gines, a major step in the development of marine 2-stroke engine was taken. After the successful in troduction of Delta Tuning, Wrtsil Switzerland Ltd is taking this development even further by intro ducing Low-Load Tuning.

A2.1

Delta Tuning

The complete flexibility in engine setting that is an integral feature of the RT-flex common-rail system, enables fuel injection pressures and timing to be freely set at all loads. It is employed in special tun ing regimes to optimize brake specific fuel con sumption (BSFC) at individual engine loads. This concept was first applied in Delta Tuning, which reduced BSFC for Wrtsil RT-flex engines in the operating range below 90 % engine load. The concept has now been extended to Low-Load Tuning, which provides the lowest possible BSFC in the operating range of 40 to 70 % engine load. With Low-Load Tuning, RT-flex engines can be op erated continuously and reliably at any load in the range of 30 to 100 %. The Low-Load Tuning concept is based on the combination of a specifically designed turbocharg ing system setup and appropriately adjusted en gine parameters related to fuel injection and ex haust valve control. The reduced part-load BSFC in Low-Load Tuning is achieved by optimizing the turbocharger match for part-load operation. This is done by increasing the combustion pressure at less than 75 % load through an increased scavenge air pressure and a higher air flow (waste gate closed), and by blowing off part of the exhaust gas flow (waste gate open) at engine loads above 85 %. The higher scavenge air pressure at part-load automatically results in lower thermal load and better combustion over the entire part-load range. Low-Load Tuning requires the fitting of an exhaust gas waste gate (a pneumatically-operated valve, see figure A2) on the exhaust gas receiver before the turbocharger turbine. Exhaust gas blown off through the waste gate is by-passed to the main exhaust uptake. The waste gate is opened at en gine loads above 85 % to protect the turbocharger and the engine from overload.

Delta Tuning makes it possible to further reduce the specific fuel oil consumption while still comply ing with all existing emission legislation. Moreover, this is achieved only by changing software para meters and without having to modify a single en gine part. Delta Tuning option needs to be speci fied at a very early stage in the project. In realising Delta Tuning, the flexibility of the RTflex system in terms of free s
