The invention relates to a liquefied petroleum gas direct injection engine (100) comprising at least one cylinder comprising a combustion chamber (1) having a spark plug (2), one or more intake valve or valves (4) and one or more exhaust valve or valves (5). The LPG engine (100) further comprises at least one injector (6) for injecting liquefied petroleum gas in liquid state directly into the combustion chamber, the LPG being injected at a pre-established pressure value; a high pressure pump (9) for feeding pressurized liquefied petroleum gas to at least one injector (6); and an electronic control unit (13) configured to operate the at least one injector (6) for injecting the LPG during a specific injection time period or periods such that a predefined target mass of liquefied petroleum gas is injected, and between 360 BTDC and 60 BTDC of the engine cycle. The invention also refers to a control method of a liquefied petroleum gas direct injection engine (100).


The object of the invention is a method implemented in a computer for the numerical simulation of a porous medium that may comprise multiple interacting hydraulic fractures in continuous or naturally fractured medium. The method calculates numerically the propagation of a crack, or set of cracks, for instance under the fluid pressure imposed artificially through a well or perforation in a rock mass. This is accomplished by using the Finite Element Method and the special elements named zero-thickness interface or joint elements in the specialized literature, which are pre-inserted along all potential crack paths in the rock mass (pre-existing natural and artificial fractures plus main potential new fracture paths).


The present invention relates to a hierarchical composite structure comprising an open cell graphene foam or graphene-like foam, wherein the graphene foam or graphene-like foam is coated with a conductive nanoporous spongy structure and wherein at least 10% v/v of the hollow of the pores of the graphene foam or graphene-like foam is filled with the conductive nanoporous spongy structure. The invention also relates to a process for preparing a hierarchical composite structure wherein a conductive nanoporous spongy structure is electrodeposited so as to coat the open-cell graphene foam or graphene-like foam and to partially fill the hollow of the pores of the graphene foam or graphene-like foam.

Large quantities of waste heat are continuously rejected from industries. Most of this waste energy, however, is of low-quality and is not practical or economical to recover it with current technologies. The Indus3Es project will develop an innovative Absorption Heat Transformer (AHT) for this purpose, focused on low temperature waste heat recovery (below 130C). The Indus3Es System will effectively recover and revalorize about 50% of the low-temperature waste heat, increasing quality of the waste source to the required temperature and reusing it again in the industrial process. The main objective is to develop an economically viable solution for industry, appropriate for new but also for existing plants and adaptable to various industrial processes. The developed system will be demonstrated in real environment in Tupras, a petrochemical industry in Turkey, enabling to analyze besides integration aspects, operational and business issues of Indus3Es System. Indus3Es System will be defined and optimized for different specificities in different sectors and industrial processes, for which up-scaling of the demonstrated technology and replication studies will be performed. Market potential evaluation and business analysis will be performed by industrial partners in order to guarantee a successful exploitation of the system in a short future. Indus3Es system will have a relevant impact making possible an energy efficiency increase and primary energy consumption of most energetic intensive industries in Europe. The embodied energy, the environmental footprint of the products and the manufacturing costs of energy intensive industries will be reduced, increasing the competitiveness of European products. Moreover, it will allow a sustainable economic activity for local auxiliary companies, usually SMEs, in high added value services related to the energy efficiency measures for industry.

This project is the second in the series of EC-financed parts of the Graphene Flagship. The Graphene Flagship is a 10 year research and innovation endeavour with a total project cost of 1,000,000,000 euros, funded jointly by the European Commission and member states and associated countries. The first part of the Flagship was a 30-month Collaborative Project, Coordination and Support Action (CP-CSA) under the 7th framework program (2013-2016), while this and the following parts are implemented as Core Projects under the Horizon 2020 framework. The mission of the Graphene Flagship is to take graphene and related layered materials from a state of raw potential to a point where they can revolutionise multiple industries. This will bring a new dimension to future technology a faster, thinner, stronger, flexible, and broadband revolution. Our program will put Europe firmly at the heart of the process, with a manifold return on the EU investment, both in terms of technological innovation and economic growth. To realise this vision, we have brought together a larger European consortium with about 150 partners in 23 countries. The partners represent academia, research institutes and industries, which work closely together in 15 technical work packages and five supporting work packages covering the entire value chain from materials to components and systems. As time progresses, the centre of gravity of the Flagship moves towards applications, which is reflected in the increasing importance of the higher - system - levels of the value chain. In this first core project the main focus is on components and initial system level tasks. The first core project is divided into 4 divisions, which in turn comprise 3 to 5 work packages on related topics. A fifth, external division acts as a link to the parts of the Flagship that are funded by the member states and associated countries, or by other funding sources. This creates a collaborative framework for the entire Flagship.

This project aims to apply the new exascale HPC techniques to energy industry simulations, customizing them, and going beyond the state-of-the-art in the required HPC exascale simulations for different energy sources: wind energy production and design, efficient combustion systems for biomass-derived fuels (biogas), and exploration geophysics for hydrocarbon reservoirs. For wind energy industry HPC is a must. The competitiveness of wind farms can be guaranteed only with accurate wind resource assessment, farm design and short-term micro-scale wind simulations to forecast the daily power production. The use of CFD LES models to analyse atmospheric flow in a wind farm capturing turbine wakes and array effects requires exascale HPC systems. Biogas, i.e. biomass-derived fuels by anaerobic digestion of organic wastes, is attractive because of its wide availability, renewability and reduction of CO2 emissions, contribution to diversification of energy supply, rural development, and it does not compete with feed and food feedstock. However, its use in practical systems is still limited since the complex fuel composition might lead to unpredictable combustion performance and instabilities in industrial combustors. The next generation of exascale HPC systems will be able to run combustion simulations in parameter regimes relevant to industrial applications using alternative fuels, which is required to design efficient furnaces, engines, clean burning vehicles and power plants. One of the main HPC consumers is the oil & gas (O&G) industry. The computational requirements arising from full wave-form modelling and inversion of seismic and electromagnetic data is ensuring that the O&G industry will be an early adopter of exascale computing technologies. By taking into account the complete physics of waves in the subsurface, imaging tools are able to reveal information about the Earths interior with unprecedented quality.
