Call for applications: education and training program for research and development experts in marine and maritime industries

The National Research Council of Italy, Institute of Marine Engineering, organizes, as part of the Project TRIM – Technology and Industrial Research for Marine Mobility (CTN01_00176_163601), the “Education and training program for research and development experts in marine and maritime industries”. Thirty (30) attendees will be selected, based on qualifications and interview. The twenty-one (21) top ranked will be awarded a € 16,200.00 scholarship (gross of taxes and of the charges borne by the CNR), the other nine (9) will be auditors.

The program addresses three alternative objectives and aims at training experts in the areas:

  • lightweight structures and new materials;
  • design techniques development for efficiency improvement;
  • development of new propulsion systems, emission control and noise and vibration management.

The program includes education activities provided by university teachers, researchers, and/or experts in the sector (480 + 180 hours) and training internships at companies/organizations of the sector (540 hours) for a total of 1200 hours in 13 months, starting December 2020.

Candidates applying for the positions should not have/have had working relationships with the bodies involved in the project and should have the specific qualifications required by the call announcement (ID: INM-001-2020-RM-Prot 0064218, Gazzetta Ufficiale n. 81 del 16/10/2020, deadline: 16/11/2020).

Project Prometeo

PROMETEO – Production of electricity, heat and cooling with a micro-cogenerator powered by residual biomass. ♦ Contract for research activity financed by Costruzioni Motori Diesel S.p.A. within the project PROMETEO, D.M. Ministro dello Sviluppo Economico 1.6.2016 Grandi Progetti R&S – PON IC 2014/2020. ♦ Project details: In recent years, energy issues have in fact assumed increasing importance in the political, economic, social and environmental spheres, a situation that has led to greater attention to the rational use of energy as well as to the use of more efficient and alternative conversion technologies globally. This context fits perfectly with the objectives of the PROMETEO project, whose primary purpose is the adoption of a practical reduction in the consumption of primary energy through the use of residual biomass for energy purposes, with a consequent reduction of climate-altering emissions. The micro-polygeneration technical solution proposed in PROMETEO can in fact be a valid alternative to traditional and polluting technologies for the production of electricity and heat at municipal and local level.

PANACEA – Polygeneration fueled with biomass from waste In urban wastewater treatment plants. ♦ Finances by Ministero dello Sviluppo Economico, Ricerca di Sistema Elettrico Nazionale, Bando 2014. ♦ Project details: The purification of urban waste water has become a growing problem both in relation to the need to build new plants and adapt existing ones to respond to the increasingly stringent initiatives of the European Community, and to the energy and environmental costs associated with these systems. Another problem is that of high energy consumption, both electrical and thermal. The analysis of the management costs of different purification plants shows that around 25-30% of the total is connected to the electricity requirement, which is why biogas is used in plants that have an anaerobic digestion section. generated for the production of electricity. However, this production is not sufficient to cover the plant’s energy needs both for the modest amount of biogas that can be produced and for its relatively low calorific value. Further costs, in the measure of 20-25%, are related to the treatment and disposal of the sewage sludge in landfills, to reduce which thermal drying systems are spreading. Read more

Compression Ignition Engines

Engine Technology: toward “Near Zero Emissions” c.i. engines

Based on its better thermodynamic efficiency with respect to the spark-ignition (SI) engine, the compression ignition engine will be the most attractive powered solution for different classes of vehicles.

The key-word for the development of  the future CI engines is “flexibility”, in terms of performance, operating mode, hardware complexity and adopted fuel.

In Istituto Motori studies and experiments are performed on various aspects of the CI engine technology and in a wide range of engine applications as:

  • Low temperature combustion concepts to accomplish the in-cylinder NOx and particulate formation control;
  • Development of base combustion system technology like high-pressure injection systems, piston bowl design and compression ratio, intake port design in order to increase performances and reduce emission and NVH;
  • Advanced air, boosting and EGR management systems, like twin-stage turbo and low-pressure EGR, to obtain better performances and fuel economy;
  • Advanced after-treatment systems, like catalysts and filters for unburned gaseous, nitrous oxide and particulate matter emission control, to comply with the severe pollutant limitations without penalties in engine performance

Spark Ignition Engines

The antithetical goals of reducing fuel consumption and emission levels, improving torque and power is currently achieved through the so-called downsizing, consisting in engine displacement reduction connected to a higher compression ratio. This approach allows to reach a better global efficiency, thanks to supercharging with variable geometry turbine (VGT).  Knock  is controlled by means of Gasoline Direct Injection (GDI), cooled EGR and Variable Valve Actuation (VVA) systems, together with the use of advanced sensors for the diagnostic of the combustion process.

In Istituto Motori, due to a long experience both in modelling and in engine management, including electronic control and fluid-dynamic field, research activities on the following topics are in progress:

  • study of the formation process of the air/gasoline mixture (in relation to the choice of the position and of the type of injectors, to the air motion depending on the geometries of intake ducts and combustion chamber) through the use of three-dimensional proprietary and open source CFD codes;
  • study of the control strategies of injection (single or multiple), ignition and EGR;
  • study and realisation of prototypes for the measurement of the ionization current between the spark plug electrodes, for the purposes of combustion and knock diagnostics and ignition control;
  • study and realisation of electro-hydraulic and electro-magnetic VVA prototypes;
  • study of heavy duty engines fuelled with NG/H2 blends on European Transient Cycle (ETC);
  • dual fuel technology with homogeneous air/fuel charge ignited by a diesel pilot injection.
