1. Two-stroke engine for hybrid cars
The numerical model was developed for a two-stroke spark ignition engine. One of the objectives of the study was to investigate the differences between a conventional engine and a linear motor. The thermodynamic cycle and the simulations were performed using the AVL Boost program. The simulation of engine operation was required to be carried out on a multidisciplinary basis because the dynamics of the piston movement of a linear motor is influenced by the quality of gas exchange, combustion quality and hydraulic system load.
The one-dimensional model of the free-piston engine was developed in AMESim, a programme created by Siemens Software.

2. System for reducing the carbon dioxide concentration from the exhaust gases of the thermal motors
The main objective of the project is to develop a system for reducing CO2 emissions, its testing on various internal combustion engines, its testing for more classic, alternative and blended fuels.
The system was tested on the AVL 5405 spark ignition engine on the single cylinder test stand in the L9 laboratory of the ICDT. Tests were carried out for different operating modes (variation of the speed in the range 1000 - 5000 rpm and load variation in the range 0 - 100%). Petrol and petrol blends with alcohols were tested in order to determine the behavior of the system for various fuels.
Endurance tests were conducted in order to determine the duration of efficiency and of utilization of the system.

3. Lost energy recovery system through exhaust gases of internal combustion engines
The research project proposes a solution that reduces CO2 emissions from road transport. The main objective of the research project is to recover a significant part of the exhaust gas energy. The proposed solution is that part of the exhaust gas energy is converted into electricity and used to power the vehicle's electrical equipment. The research project can slightly influence the advancement in the field of energy management of internal combustion engines. The originality of the project is given by the modality of dealing with the issue of efficiency of the equipment of mechanical energy conversion - electricity, in order to increase the reduction of fuel consumption and CO2 emissions.
In this respect, the project aims at using conventional technologies, already existing on motor vehicles, but used in an innovative way.

14. Study of road traffic for Cernavoda
Carrying out a study on the urban road network required undergoing some important steps in order to collect, analyze, process and interpret the necessary data. In the first stage of defining the road network, a first step was to identify the existing problems and to define their potential causes. For this purpose, the tasks involved activities targeted to: collecting information; defining problems and causes.
The data collection stage meant making up a history of traffic conditions referring to traffic volumes, geometric elements of the road network, road safety, etc.
These data were used both to identify operational and road safety issues and to identify their causes. The evaluation process was also based on notification of problems in certain areas and intersections. In general, local officials centralize certain categories of information that form the basis for formulating the need to conduct a study.
