    • Calculating method of heavy diesel engines emissions toxicity 

      Pikūnas, Alvydas; Bureika, Gintautas; Grabys, Juozapas (Journal of Kones. Internal Combustion Engines, 2005)
      The method to calculate harmful compounds of exhausts gases from Diesel engines is presented in this topic. It is believed that vehicles with internal combustion engines in European countries release about 89% of COx 52% ...
    • Increasing service life of major parts of internal combustion engines 

      Pikūnas, Alvydas; Garbinčius, Giedrius (Journal of Kones. Internal Combustion Engines, 2001)
    • Influence of composition of gasoline - ethanol blends on parameters of internal combustion engines 

      Pikūnas, Alvydas; Pukalskas, Saugirdas; Grabys, Juozapas (Journal of Kones. Internal Combustion Engines, 2003)
      The purpose of this study is to investigate experimentally and compare the engine performance and pollutant emission of a SI engine using ethanol-gasoline blended fuel and pure gasoline. The results showed that, when ethanol ...
    • Investigation of automobile active safety control systems efficiency and their impact on the driver's behaviour 

      Bureika, Gintautas; Kilikevičienė, Kristina (Journal of KONES. Powertrain and transport / Permanent Commitee of Kones, Institute of Aeronautics, Automotive Industry Institute, Polish Academy of Science, 2012)
      The paper deals with the influence of active car safety systems on driver's behavior in emergency situations, i.e. emergency braking, steering angle, etc. Several models of real vehicles have been tested in order to analyse ...
    • Investigation of effiency of consuming ethanol of diesel engine 

      Pikūnas, Alvydas; Pukalskas, Saugirdas; Bureika, Gintautas; Grabys, Juozas (Journal of KONES. Powertrain and transport / Permanent Commitee of Kones, Institute of Aeronautics, Automotive Industry Institute, Polish Academy of Science, 2006)
      Renewable resources, searching for alternative energy and its application in motor vehicles became particularly urgent now, when oilfields are approaching to their depletion and prices of hydrocarbon fuel are permanently ...
    • Research of operation of a diesel engine with supplementary ethanol feed 

      Pikūnas, Alvydas; Grabys, Juozapas; Pukalskas, Saugirdas; Pečeliūnas, Robertas (Journal of Kones. Internal Combustion Engines, 2002)
      The present paper describes tests carried out with diesel engine fed with ethanol (in addition to diesel oil) supplied by various systems.
    • Research of the car braking process 

      Mitunevičius, Valentinas; Pikūnas, Alvydas; Nagurnas, Saulius (Journal of Kones. Powertrain and transport / Permanent Committee of KONES, Institute of Aeronautics, Automotive Industry Institute, Polish Academy of Sciences, 2006)
      This paper describes analysis of a car braking process - the peculiarities of car wheel-to-road adhesion, the influence of distribution of braking forces on car stability between front and rear axles. Structural designs ...
    • Research on Hazardous effect of petrol-ethanol blend's emissions in spark ingnition engines 

      Bureika, Gintautas; Pikūnas, Alvydas; Grabys, Juozapas (Journal of Kones. Powertrain and transport / Permanent Committee of KONES, Institute of Aeronautics, Military University of Technology, Polish Academy of Sciences, 2008)
      This paper deals with ecological aspects of using alcohol fuels in spark ignition (SI) engines, determining ecological characteristics of SI engine for various fuels. The dependence of the emission of hazardous material-carbon ...
    • The influence of diesel engine's thermal condition on fuel consumption and smoke of exhaust gases 

      Pukalskas, Saugirdas; Pikūnas, Alvydas; Bureika, Gintautas (Journal of KONES. Powertrain and transport / Permanent Commitee of Kones, Institute of Aeronautics, Automotive Industry Institute, Polish Academy of Science, 2009)
      The number of vehicles in the world is growing rapidly. Therefore, the global consumption of crude oil is increasing and its natural resources are being depleted. It causes the rise of oil fuel cost. Constantly rising ...
    • The influence of methanol on ecological and energetic parameters of SI engines 

      Pikūnas, Alvydas; Pukalskas, Saugirdas; Grabys, Juozapas; Mikaliūnas, Šarūnas (Journal of Kones. Internal Combustion Engines, 2004)
      One of the most effective methods to reduce air pollution by SI engine exhaust emission is the use of alcohol though due to its hygroscopicity it makes unstable blends with gasoline. The present paper describes the impact ...
