    • Analysis of the Combustion Process of a Compression Ignition Engine Running on Diesel and Natural Gas 

      Stravinskas, Saulius; Rimkus, Alfredas; Kriaučiūnas, Donatas (Proceedings of the International Conference TRANSBALTICA XI: Transportation Science and Technology. May 2–3, 2019, Vilnius, Lithuania, 2020)
      Compression ignition (CI) engines, although significantly contribute to environmental pollution, are still widely used in transport sector. In order to reduce usage of fossil fuels and environmental pollution, but at the ...

    • Comparative Analysis of Energy and Ecological Indicators of a Spark Ignition Engine Running on Different Amount of Petrol and Bioethanol 

      Mejeras, Gabrielius; Rimkus, Alfredas (Proceedings of the International Conference TRANSBALTICA XII: Transportation Science and Technology. September 16-17, 2021, Vilnius, Lithuania, 2022)
      Results presented in experimental study, which extends of numerical modeling studies of petrol mixed with 10% bioethanol (E10), bioethanol mixed with 15% petrol (E85). During the test AVL BOOST program with modeled HR16DE ...

    • Comprehensive Methodology for Comparative Environmental Assessment of Vehicles 

      Valiulis, Edvinas; Pukalskas, Saugirdas (Proceedings of the International Conference TRANSBALTICA XII: Transportation Science and Technology. September 16-17, 2021, Vilnius, Lithuania, 2022)
      The negative impact of transport on the environment and the ways of ecological mobility are analysed in this paper. It is also highlighted that publicly recognised ecological vehicles – electric cars – are not absolutely ...

    • Energy and Ecological CI Engine Indicators Having Replaced Diesel with Chicken Fat 

      Rimkus, Alfredas; Vipartas, Tadas; Matijošius, Jonas; Stravinskas, Saulius; Shepel, Oleksandra (Proceedings of the International Conference TRANSBALTICA XI: Transportation Science and Technology. May 2–3, 2019, Vilnius, Lithuania, 2020)
      Diesel-powered compression ignition (CI) engines use fossil fuels, which results in increasing greenhouse gas emissions and environmental pollution. Chicken fat, which is attributed to renewable fuels, is one of possible ...

    • Overview of Problematic Aspects of Passenger Car Hybrid Technologies 

      Vipartas, Tadas; Rimkus, Alfredas; Zöldy, Máté (Proceedings of the International Conference TRANSBALTICA XII: Transportation Science and Technology. September 16-17, 2021, Vilnius, Lithuania, 2022)
      Hybrid electric vehicles (HEV) with Atkinson cycle engines typically use variable valve timing (VVT) technology that reduces fuel consumption up to 30% due to the delay in closing intake valve. Engine thermal efficiency ...

    • Research of Automatic Rotational Frequency Control Systems of Automobile Diesel Engine 

      Lisoval, Anatolii; Rimkus, Alfredas (Proceedings of the International Conference TRANSBALTICA XII: Transportation Science and Technology. September 16-17, 2021, Vilnius, Lithuania, 2022)
      The purpose of the research is to compare the quality indicators of speed control of the automobile diesel engine with all-mode mechanical and microprocessor regulators in steady state conditions and in transient. Comparative ...

    • Research of Vehicle Airbag Non-deployment Cases 

      Pečeliūnas, Robertas; Pasaulis, Tomas (Proceedings of the International Conference TRANSBALTICA XII: Transportation Science and Technology. September 16-17, 2021, Vilnius, Lithuania, 2022)
      In this paper, the conditions, criteria and the algorithms controlling the deployment of vehicle airbags are analysed. The sequence of the algorithm and specific thresholds used in airbags control are analysed as well. The ...

    • Reviewing the Concept of Acoustic Agglomeration in Reducing the Particulate Matter Emissions 

      Rayapureddy, Sai Manoj; Matijošius, Jonas (Proceedings of the International Conference TRANSBALTICA XII: Transportation Science and Technology. September 16-17, 2021, Vilnius, Lithuania, 2022)
      Air pollution is one of the world’s major growing concern. Particulate Matter, which is a complex mixture of solid or liquid airborne particles, is one of the predominant emissions that shows a drastic impact on human ...

    • Side Impact Analysis of the Bus Frame Structure 

      Pravilonis, Tautvydas; Sokolovskij, Edgar (Proceedings of the International Conference TRANSBALTICA XII: Transportation Science and Technology. September 16-17, 2021, Vilnius, Lithuania, 2022)
      Vehicle bodies and structures should be designed to absorb and redistribute as much impact energy as possible, thus protecting the driver and passengers from injury. The deformation zone of the vehicle in the case of a ...
