Table A1 Primary engine data of Wrtsil RT-flex50-B

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 selection of injection and exhaust valve control parameters, specifically variable injection timing (VIT) and variable exhaust closing (VEC) is utilised for reducing the brake spe cific fuel consumption (BSFC) in the part load range below 90 % load. Due to the trade-off between BSFC and NOx emissions, the associated increase in NOx emissions at part load must then be compensated by a corresponding decrease in the full load NOx emissions. Hence, there is also a slight increase in full load BSFC, in order to maintain compliance of the engine with the IMO NOx regulations. The concept is based on tailoring the firing pres sure and firing ratio for maximum efficiency in the range up to 90 % load and then reducing them again towards full load. In this process, the same design-related limitations with respect to these two quantities are applied as in the specification of the Standard Tuning. The reliability of the engine is by no means im paired by the application of Delta Tuning since all existing limitations to mechanical stresses and thermal load are observed.

Introduction

A Wrtsil RT-flex engine with Low-Load Tuning complies with the IMO Tier II regulations for NOx emissions. The engine parameters controlling the fuel injec tion and exhaust valve operational characteristic have to be selected appropriately in order to allow realizing the full potential of the concept while en suring compliance with the applicable NOx limit value. On the one hand, these parameters have toWaste gate

be specified in such a way that the transition be tween the bypass-closed and bypass-opened op erating ranges can be realized as smooth as pos sible. On the other hand, higher scavenge air pressure trendwise increases NOx emissions hence, for achieving the same weightened aver age value over the test cycle, the parameters also need to be adjusted appropriately for compensat ing this increase.

Further aspects of engine tuning optionsProject specification for RT-flex engines: Although Delta Tuning is realised in such a way that it could almost be considered a pushbutton op tion, its selection as well as the selection of LLT have an effect on other aspects of engine and sys tem design as well. Therefore the tuning option to be applied to RT-flex engines needs to be specified at a very early stage in the project: The calculations of the torsional and axial vibrations of the installation have to be per formed using the correct data. The layout of the ancillary systems has to be based on the correct specifications. In order to prepare the software for the RT-flex system control, the parameters also have to be known in due time before commissioning of the engine.

Tuning for de-rated engines: For various reasons, the margin against the IMO NOx limit decreases for de-rated engines. Delta Tuning and Low-load Tuning thus holds the highest benefits for engines rated close to R1. With the de-rating, the effect diminishes and, in fact, Delta Tuning is not applicable in the entire field (see figure A3). Effect on engine dynamics: The application of Delta Tuning or Low-Load Tun ing have an influence on the harmonic gas excita tions and, as a consequence, the torsional and axial vibrations of the installation. Hence, the corresponding calculations have to be carried out with the correct data in order to be able to apply ap propriate countermeasures, if necessary.
