Several R&D centres herein undertake the investigation of the reduction of the abnormal combustion phenomena of knock in internal combustion engines. Combustion knock limits the efficiency of the engine and deteriorates engine performance while simultaneously contributing to engine destruction, hence reduces engine reliability. Reducing or eliminating combustion knock increases durability and also engine efficiency, hence reducing CO2 emissions. The inter-sectoral research encompassed in this proposal concerns high-power stationary engines fuelled with gaseous fuels working in combined heat and power (CHP) systems. The proposal intends to apply a multidisciplinary approach to knock investigation encompassing fuel chemistry, combustible mixture preparation, ignition phenomena, flame propagation, knock detection and its prediction. Both modelling studies and experimentation in these fields will be performed. As result of the synergies and breadth of expertise, a resultant acceleration in research finding is expected with complementary investigation conducted within both the companies (Wartsila, AVL, Motortech) and universities involved that finally should result in solving the related challenges. Knowledge exchange will be done by research staff secondments, where experienced scientists will work both as advisors and active researchers in the ongoing projects. Engineers coming to universities will be familiar with original techniques for data acquisition as well as methods for signal processing and theoretical analysis of combustion process in the engine. Young research staff from companies will have opportunities to work with academic mentors. Further academic staff will become familiar with industrial approaches to research extending the knowledge. Knowledge transfer will be also done through regularly scheduled seminars and webinars. This collaboration and staff exchanges between the participants build lasting ties and continued after project termination.

HERCULES was conceived in 2002 as a long-term R&D Programme, to develop new technologies for marine engines. It is the outcome of a joint vision by the two major European engine manufacturer Groups MAN & WARTSILA, which together hold 90% of the worlds marine engine market. The present proposed HERCULES-C project is the Phase III of the HERCULES Programme. In order to take marine engine technology a step further towards improved sustainability in energy production and total energy economy, an extensive integration of the multitude of the new technologies developed in Phases I and II is required. HERCULES-C addresses this challenge by adopting a combinatory approach for engine thermal processes optimization, system integration, as well as engine reliability and lifetime. The first Objective of HERCULES-C is to achieve further substantial reductions in fuel consumption, while optimizing power production and usage. This will be achieved through advanced engine developments in combustion and fuel injection, as well as through the optimization of ship energy management and engine technologies supporting transport mission management. The second Objective of HERCULES-C is to achieve near-zero emissions by integrating the various technologies developed in the previous research Projects, in Phases I and II. The third Objective is to maintain the technical performance of engines throughout their operational lifetime. This requires advanced materials and tribology developments to improve efficiency and reliability, as well as sensors, monitoring and measurement technologies to improve the controllability and availability of marine power plants. The project HERCULES-C structure of RTD work comprises 47 Subprojects, grouped into 10 Work Packages and 5 Work Package Groups, spanning the complete spectrum of marine diesel engine technology. The HERCULES-C Project has duration of 36 months, a Consortium with 22 participants. and a total budget of EUR 17 million.

The specific challenge for waterborne transport call MG4.1 is, To support developments that make new and existing vesselsmore efficient and less polluting. A sound way to support developments is, to demonstrate solutions that are sufficiently close to market so that ship owners will consider these in their future investment plans. Following this reasoning LeanShips will execute 8 demonstration actions that combine technologies for efficient, less polluting new/retrofitted vessels with end users requirements. Demonstrators were selected for their end-user commitment (high realisation chance), impact on energy use/emissions, EU-relevance, innovativeness and targeted-TRL at the project end. Selected technologies (TRL3-4 and higher) address engines/fuels/drive trains, hull/propulsors, energy systems/emission abatement technologies. Technologies are demonstrated mostly at full-scale and evidence is provided on energy and emission performance in operational environments. The LeanShips partnership contains ship owners, shipyards and equipment suppliers, in total 48 partners from industry (81%) and other organisations. Industry has a leading role in each demonstrator. Target markets are the smaller-midsized ships for intra-European waterborne transport, vessels for offshore operations and the leisure/cruise market. First impact estimates show fuel saving of up to 25 %, CO2 at least up to 25%, and SOx/NOx/PM 10-100%. These estimates will be updated during the project. First market potential estimates for the LeanShips partnership and for markets beyond the partnership are promising. Project activities are structured into 3 layers: Basis layer with 8 focused demonstrators (WP 04-11), Integration layer with QA, Innovation Platform and Guide to Innovation (WP02), Dissemination and Market-uptake (WP03), and top Management layer (WP01), in total 11 Work Packages. The demonstrators represent an industry investment of ca. M 57, the required funding is M 17,25.

The main objectives of this proposal is to evaluate different process alternatives and find optimal process and mechanical solutions for the cathode and stack subsystems with the aim of having commercially feasible and technologically optimised subsystem solutions ready for future ~ 250 kWe atmospheric SOFC systems. The aspects taken into account in the development are mainly electrical efficiency, controllability, reliability, mass production and costs effectiveness of developed subsystems and individual components. This project is focused on the development of SOFC systems air side fluid and thermal management and mechanical solutions, i.e. cathode subsystem and individual components. In large SOFC systems the cathode subsystem is typically the largest source of auxiliary losses and a major factor decreasing electrical efficiency of the system. The reason for this is that almost all components are based on existing products developed for some other purposes and are not optimized for certain SOFC systems. By making cathode side components from the SOFC system point of view, i.e. optimizing the overall system solutions, significant improvements in terms of costs, reliability, performance and lifetime will be achieved. A parallel optimization of the anode subsystem is carried out in the EU funded ASSENT project. The project will further focus on the integration of SOFC stacks in large systems. If large SOFC systems would be realized by simple multiplication of smaller SOFC stacks, the cost of the so-called Balance of Stack components would be very large. The Balance of Stack components includes air- and gas manifolding, stack compression, thermal insulation, electrical insulation, wiring, lead-ins and sealing. Based on state-of-the-art SOFC stacks this project will develop scalable, cost-efficient Balance of Stack solutions suitable for ~ 250 kW SOFC systems.

Reducing emissions from shipping has increasingly become a challenge over the last years, both as a counter measure against global climate change and to protect local environments and population from waste, gas emissions and noise. This challenge has been documented both in policy papers, like the Europe 2020 initiative or the Transport White Paper, and in rules and regulations issued by IMO as well as by local authorities. Those legislations as well as emission taxes and an increasing public awareness on green shipping have led to the fact, that low emission ships and shipping has become a key competitive factor both for European shipbuilders (including equipment manufacturers and shipyards) and shipping companies. In response to topic SST.2013.1-2 of the Sustainable Transport Work Programme 2013 the JOULES proposal aims to significantly reduce the gas emissions of European built ships, including CO2, SOx, NOx and particulate matters. JOULES follows an integrated and holistic approach, not only limited to integrating the components of the simulation of the energy grid, but through the consideration of other viable options for emission reduction. The specific optimal solutions for emission reduction and energy efficiency highly depend on the transport or service task of ships, as well as on their operational profile. While a wide overview and holistic assessment of all available energy and emission saving technologies is necessary, industrial breakthrough can only be achieved if the available solutions are selected, adopted, integrated, assessed and finally demonstrated for realistic application cases. The binding element between technologies and applications are modelling and assessment methods and tools. Those are needed to predict the behaviour of complex energy grids, to manage the energy demand in operation and to assess the performance of optimized energy grids both in view of cost efficiency and environmental impact.

The method controls timing of a discharge event of a centrifugal separator, during which discharge event at least part of a heavier liquid and/or sludge or solids separated from a lighter liquid is discharged from the separator through at least one discharge opening. The discharge opening is opened and/or closed hydraulically. The method comprises the steps of waiting for a scheduled discharge time, measuring the pressure of the liquid used for opening and/or closing the discharge opening, comparing the measured pressure to a predetermined limit value, and, in the case the pressure is below the limit value, delaying the discharge event.
