The response of the piston internal combustion engine provides an important indicator to assess the engine ability to adapt to constantly varying load conditions in its operation. It is the main criterion by which engines powering automotive vehicles are evaluated. It also affects road safety. The engine response depends on the profile of the curve that shows changes in the engine torque as a function of the crankshaft rotational speed. The paper presents a comparison of CI engines representing different generations with respect to constructional level. The engines that underwent comparison were equipped with the fuel system with a rotary injection...

The paper presents results of investigations into the AD3.152 UR engine running on five fuels: commercial diesel oil DO, rapeseed oil fatty acid methyl esters FAME and their blends B10 (90% DO + 10% FAME), B20 (80% DO + 20% FAME), B30 (70% DO + 30% FAME). During the tests, the engine operated in accordance with the full load characteristics. Those characteristics were used to determine the engine response. The paper provides an assessment of the impact of the type of plant-derived fuel on the engine response.
Software Architecture of an Information System for Aviation Broker Center

Based on the London's airports example it is obvious that there are differences between 3rd level airports. If the same coordination system would be introduced within various coordinated airports it could lead to various results. The results of analysis of intra-EU route data indicate that larger aircraft have been used at the 3rd level airports and there is no strong evidence of inefficient slot hoarding at these airports, not only before but also after the EC's recognition of secondary slot trading. In contrast, the analysis of slot trading at Heathrow and Gatwick show that slot trading has taken place more likely within alliance and the chances...
Choosing the Suitable Method for Multimodal Logistics Object Location in the Slovak Republic and Setting up the Criteria Matrix
Ondrej Stopka, Ivana ©imková
Transport And Communications 2014, 2(1):16-20 | DOI: 10.26552/tac.C.2014.1.5
This paper deals with the choosing of a suitable method for multimodal logistics object location in the Slovak Republic. The paper also describes several methods concerning the multimodal logistics object location in particular area, determines the crucial method related to this issue and presents setting up the criteria matrix for the needs of this object location in the Slovak Republic.
