Taking into consideration the quality of air, it is necessary to ensure a continued reduction gaseous emissions that are produced by maritime transport. The most effective solution this serious worldwide problem application suitable fuel mixture, which contains bio-component, i.e. biofuel. presented scientific study focused on influence biofuels production in case diesel auxiliary engine, used ship There were created various mixtures with different content bio-component order investigate...

On the present, a considerable reduction of greenhouse gas emissions is one most important challenges in construction motorcars and their driving units.Application biofuels essentially contributes to air pollution caused by exhaust gases.However, application bioethanol as fuel spark ignition engines requires perform some constructional adjustments these order ensure proper functioning eliminate potential operational risks.The scientific publication focused on creation simulation model...

Large transoceanic ships use marine ancillary diesel engines for generating electricity, which, on the other hand, produce a remarkable amount of harmful emissions during combustion process. The International Maritime Organisation (IMO) establishes standards that limit produced engine cycle in maritime transport. Because this restriction, new alternative fuels entered market. Experiments had been performed with various testing created from biodiesel and ULSD-F (Ultra Low Sulphur Diesel-Fuel)...

Abstract The transport sector generates up to one quarter of greenhouse gas emissions. Transport is also the main polluters in urban agglomerations. This has an impact on quality environment and human health. Road traffic emissions constitute 70% total sector. automotive industry under growing pressure reduce significantly utilize alternative sources energy, among which bio‐renewable play a very important role. An task scientific publications analyze influence fuels with different...

Historical maps represent a unique and irreplaceable source of information about the history country, be it large (historical) regions, individual geomorphological units or specifically defined sites. Using methodologically correct, critical historical analysis, old provide both horizontal vertical analysis landscape its transformation in different time periods. These some oldest, but relatively easily accessible, pictorial documents (plausibly) depicting landscapes. This study provides...

Abstract The automotive industry is exposed to continued pressures, the goal of which decarbonisation together with application advanced technologies and fuels, as well utilization alternative vehicle drives. main task scientific publication was a complex emission analysis selected vehicles during various test cycles, comparison individual emissions when using different types fuel.

This study examines sustainability in tourism, with a particular focus on enhancing destination management through comprehensive visitor monitoring. Precise data volumes constitute an essential prerequisite for the sustainable planning and of tourism-related services infrastructure. research investigates correlation between attendance utilization centers, employing regression analysis Kolmogorov–Smirnov test to quantify these relationships. The specifically addresses distribution domestic...

Thanks to its carbon-free nature, it is possible say that hydrogen a potential fuel for future automotive systems. Its main favourable properties include high burning rate, wide range of flammability and low ignition energy. In combination with hybrid electric technology, the combustion engine has further development goal maximum efficiency in energy conversion. For more efficient combustion, dual injection system designed, where one injector designed direct into cylinder other supply...

The scientific contribution is focused on the analysis and optimization of combustion conditions concerning dual-fuel mixtures. greatest attention was paid to temperature intake air when a mixture ethanol gasoline created applied fuel. An experimental fuel added into pipe ultra-low sulphur diesel (ULSDF) directly engine cylinder using CR (common rail) injection system. article analysed medium- high-level operational load, whereby timing parameters originally corresponded conventional engine....

The most serious problems to overcome for a successful operation of the HCCI engine are control combustion phase, limited operational range, cold start and high noise level during operation. This study aims at describing power output characteristics emission engines under different testing conditions various challenges associated with these engines. Furthermore, this holds potential guide overcoming improvement as well characteristics. Thus, it is possible say, concerning performed...

The innovative system, which was developed for analysis and correction of motor management, is determined the solution practical problems concerning operation piston combustion engines. Programming ignition curves fuel maps without relevant feedback, namely, information obtained from engine operation, increases risk detonation combustion, can destroy engine. However, main application area this system development an algorithm, specified control process based on HCCI technology (Homogenous...

The presented scientific study deals with the environmental and energetic aspects concerning application of experimental fuels in high-powerful engines. This analyses most important results from tests realised on motorbike engine case two testing regimes: at first using a standardly produced combustion then adjusted configuration designed order to improve efficiency process. There were tested compared each other three different framework research work. fuel was top 4-SGP, which is...

Nowadays, the research and development activities performed in area of internal combustion engines are focused on LTC technologies, especially HCCI technology. It is so because these innovative technologies characterized by high operational efficiency as well low emissions nitrogen oxides (NOX) particulate matter (PM). The process able to utilize various fuels. kind fuel, together with its physical chemical properties have a major influence engine power output gaseous emissions. presented...

This article analyses the influence of various configurations concerning homogenisation system on output parameters an experimental engine.The results presented in this were obtained using dynamometric measurement.A modular approach to individual measurements consists a sequential formation configurations.The experimentally are matches with analytical relations, which described related literature.These can be for wide spectrum high-powerful engines because does not depend construction and...

Engine emissions can be reduced by performing suitable modifications to the oil filter. Biomass medium served as replacement for standard paper fibres, which are used in common filters. The experimental analysis of 4 emission elements showed a moderate increase case 2 characteristics, whereby 10% monoxide was present, and also, an 2.5% nitrogen oxides observed. Further, there significant reduction other elements, namely unburned hydrocarbons decreased 61%, amount particulate matter 18%....
