Pure conventional fuel second generation hydrotreated vegetable oil (HVO) (Neste) used in research. Natural gas contained 97 vol. % methane. Biogas...

Road transport is one of the most important factors for national economy due to its universality and comprehensive possibilities transporting people goods. Unfortunately, from energy point view, it also cost-intensive has a negative influence on natural environment. For these reasons, issues related limiting use conventional fuels are very important, which results in reducing emissions this sector, as well costs. This article presents currently used sources propulsion road vehicles,...

The reliability of internal combustion engines becomes an important aspect when traditional fuels with biofuels. Therefore, the development prognostic models very for evaluating and predicting replacement biofuels in engines. have been made to model AVL 5402 engine emission, vibration, sound pressure parameters using a three-stage statistical regression models. fifteen might be accurately predicted by single statistic presented here. Both fuel type (diesel HVO) that can adjusted were...

The increasing number of electric vehicles is forcing new solutions in the field charging infrastructure. One such solution photovoltaic carports, which have a double task. Firstly, they enable generation electricity to charge vehicles, and secondly, protect vehicle against excessive heating its interior. This article presents functioning small carport for an vehicle.

Noise pollution presents significant challenges for urban infrastructure management, highlighting the need practical assessment tools such as noise maps. These maps enable visualization and geo-referencing of levels, identifying areas requiring immediate intervention long-term strategic responses. Road sections with traffic exceeding 3 million vehicles per year were selected measurement. The findings are presented in detail, revealing that Long-term Day-Night Average Level (Lden) exceeds...

Corporate operations, especially in logistics, have been greatly affected by global instability caused events like the COVID-19 pandemic and Ukraine war. This study looks at how sustainable human resource management (HRM) strategies are used Lithuanian logistics industry during crises. It focuses on organizations stay strong, stress factors involved, employees adjust. We a method that understanding people’s experiences to find important challenges effective solutions, based input from...

Using the standardised SORT, article analyses instantaneous energy consumption and recuperation processes in an electric bus. The test includes three scenarios: SORT 1 (heavy urban traffic), 2 (mixed driving conditions), 3 (suburban routes), enabling precise assessment of efficiency vehicles while eliminating environmental variables. system significantly enhances efficiency, though its effectiveness varies based on scenario. Modelling methods were compared as follows: linear regression, KNN...

The formation of raster structures on stainless-steel tapes requires high-precision mechatronic systems to ensure accuracy and stability during the process. This article gives a thorough look at redesigned precise system that can make coded or linear scales using dynamic laser These are critical components in measuring systems, such as optical encoders, where reliability paramount. One challenge is maintaining tape dynamics mitigate errors caused by slippage tape-roller interface mechanical...

This paper investigates the emission characteristics of hydrogen-enriched gasoline (95G5H2) under dynamic driving situations in order to fulfill growing need for cleaner and more efficient automobile fuels. study aimed investigate impact hydrogen addition on pollutant-specific emissions, including CO, CO2, HC, NOx, using a Nissan Qashqai that ran both pure (100G) 95G5H2. Emission statistics were obtained by computer simulations Worldwide Harmonized Light Vehicles Test Cycle (WLTC) applied...
