Opis:
Climate change, environmental degradation and the introduction of increasingly restrictive legal regulations mean that the automotive industry is facing tremendous challenges. The paper presents a computer tool that uses the results of tests carried out on a chassis dynamometer for a Fiat Panda 1.3 Multijet, to simulate driving tests. As a result of the work of a computer tool, the impact on CO2 emissions was analysed in the context of CADC - Artemis (Common Artemis Driving Cycles) road tests for the following fuels: diesel oil, FAME (Fatty Acid Methyl Esters), rapeseed oil and butanol. Mass consumption of fuels and CO2 emissions were analysed in driving tests for the vehicle in question. The highest mass consumption of fuel and carbon dioxide emissions occurred in the case of FAME (respectively 2.283 kg and 6.524 kg).

Opis:
Fossil fuel is the main source for CO2 emissions that causes global warming. This fact is the starting point for this paper, that consider on three different sources of data: crude oil used to calculate CO2 emissions for Iraq for the period from 1980 to 2018; annual data of total CO2 emissions available from the Carbon Dioxide Information Analysis Center (CDIAC) for Iraq and the world for the period from 1980 to 2014; and CO2 concentrations for Iraq for the period from 2002 to 2006 and for the world for the period from 1980 to 2018. The result is a multifaceted according to the dataset sources. Carbon dioxide emissions calculated from Iraqi crude oil was increased from 1.29 Mt in 2012 to 1.97 Mt in 2018. The world and Iraq CO2 emissions with different slop of average line that was 0.5 for world, 0.003 for Iraq, while increased exponential function from 2008 to 2014 to reach 36 and 0.17 Mt, respectively. The highest value of Iraqi CO2 concentration was 403 ppm in 2016, while the global CO2 concentrations slowly increased with slop line equal to 1.75 ppm per year, from minimum value of 338.6 ppm was in 1980, while maximum value of 407.05 ppm was in 2018, that’s mean no decreased in CO2 concentration unless emissions addressed.

Opis:
This paper describes the analysis and conclusions regarding the use of butanol/biobutanol as a component of conventional mineral fuels employed in different areas of transportation. Butanol from biomass - biobutanol is interesting as biocomponent of gasoline, diesel fuel as well as aviation fuels. This is especially important in case of air transport, which is the carbon dioxide emission source of the fastest growth. Biobutanol is tested as biocomponent of gasoline, including aviation ones, but there are no information about biobutanol added to mineral Jet fuel as well as diesel fuel. Direction of research conducted by leading aviation companies indicates that hydrocarbon biocomponent will be main biofuel used as aviation turbine fuel. One of reported technology is focused on use of butane-1-ol as semi-finished products for isoparaffinic hydrocarbons generation that then would be used for aviation turbine fuels production. In order to do such analysis the preliminary lab testing of blends of butanol isomers with aviation fuel Jet A-1 and diesel fuel were performed. The paper contains the results of standard tests for blends of mineral fuels with butane-1-ol and butane-2-ol added in concentration of 0-20 %(V/V). Both the advantages and disadvantages regarding the use of such component of mineral fuels are presented. Butanol decreases value of flash point and significantly influence on conductivity of Jet fuel. In case of aviation fuel for turbine engines, and diesel fuel, the restrictions regarding direct use of butanol are important. However, butanol can be treated as semi-finished material for synthesizing of biohydrocarbons used in above applications.

Opis:
The automotive market is developing very dynamically. In recent years, we can observe activities of automotive concerns in the production of new models of electric, hybrid and hydrogen vehicles, and conventional cars are supplied with increasingly economical and low-emission engines. There are also increasingly stringent standards related to exhaust emissions from the exhaust system. From September 1, 2018, passenger cars have to comply with the Euro 6d-Temp emission standard and be homologated according to the WLTP test procedure including the WLTC driving cycle and emission measurements in road traffic conditions. The exhaust components measured during the test, such as carbon oxides, nitrogen oxides or hydrocarbons, are toxic to living organisms. However, it seems that the most important issue in the long term may be the value of carbon dioxide emissions, the excess of which poses an ecological threat to the entire planet. The production of new vehicles equipped with modern complicated combustion engines, batteries, fuel cells and electronic devices is associated with a very high emission of this greenhouse gas The authors of the following article, based on their own research, sought to estimate the ecological profitability of replacing a used passenger car meeting the Euro-4 emissions standard for a new vehicle bearing in mind the value of carbon dioxide emissions during vehicle production. The analysis was to indicate how intensive the annual operation of the vehicle should be to make it profitable to recycle and replace it with a modern car with lower emissions considering the global sum of carbon dioxide emissions.

This paper presents a comparison of two approval tests for a passenger car, both the current procedure and its predecessor. The car that was the subject of the study received a roadworthiness certificate based on the NEDC test, however, the emission results were compared with the new test procedure. The analysis showed the significance of the "start-stop" system in the conducted tests, however, assuming the original equipment of the car (active "start-stop" system), the WLTP test showed higher CO2 emissions, which did not exceed the permissible emission standard for this model specified in the relevant regulation.
Niniejsza praca przedstawia porównanie dwóch testów homologacyjnych dla samochodu osobowego, zarówno aktualnie obowiązującą procedurę jak i jej poprzednika. Samochód, który był obiektem badań, świadectwo dopuszczenia do ruchu otrzymał na podstawie testu NEDC, jednakże porównano wyniki emisji z nową procedurą testową. Dokonana analiza wykazała istotność systemu „start-stop” w przeprowadzonych badaniach, zakładając jednak oryginalne wyposażenie auta (aktywny układ start-stop) test WLTP wykazał wyższą emisję CO2, jednakże nie przekroczyła ona dopuszczalnej dla tego modelu normy emisyjności określonej w stosownych przepisach.

Opis:
Electric or hybrid vehicles are becoming increasingly common on roads. While electric vehicles are still more or less intended for city traffic, hybrid vehicles allow normal use due to wider driving range. The use of internal combustion engines in hybrid drives is still an inspiration to find the way to reduce the production of emissions. Numbers of alternative energy resources were studied as a substitution of conventional fuels for hybrid vehicles drives worldwide. The paper deals with the possibility of using alternative fuels as CNG, LPG and LNG in combination with hybrid drive of a midibus with the capacity of 20 passengers. Various aspects and techniques of hybrid vehicles from energy management system, propulsion system and using of various alternative fuels are explored in this paper. Other related fields of hybrid vehicles such as changes of vehicle weight or influence of electric energy sources on the total vehicle emission production are also included.

Occupants protection during vehicle crash is one of the major problems considered at vehicle designing stage. The increasing safety as well as comfort requirements results in the total vehicle weight increase. On the other hand, higher mass influence on the fuel economy of vehicle. Thus, it is very important to maintain or even reduce vehicle weight. One of the solutions of this problem is application of a new materials having good strength-to-weight ratio i.e. high strength steels (HSS). They are often used in protective and energy absorbing structures in automotive industry. One of HSS so-called austenitic steels are characterized by excellent mechanical properties such as: high strength, strong strain, and strain rate hardening. Those mechanical effects are consequence of microstructural evolution during strong deformations i.e. twinning and phase transformation. As a consequence those steels are very good material for the purposes of energy absorbing and protective structures. This article presents the results of mechanical properties tests of VP159 austenitic steel. On the basis of experimental data, the JC constitutive model has been calibrated. The obtained results were used for the computer simulations of energy absorbing of square profiles made of analysed material. The results were compared with other types of steel.

Opis:
A lot of attention is nowadays devoted to the problem of generally defined ecology. It is absolutely essential in case of systems and sources generating heat due to their direct influence on the environment through emitting post-process products to the atmosphere which are, most frequently a result of combustion. Therefore, constant searchers are made to optimize the operation of heat sources and to acquire energy from sources for which the general balance of carbon dioxide emission is zero or close to zero. This work compares the emissions of equivalent CO2 from selected systems with the following heat sources: coal, gas furnace, heat pump, and refers results of the analysis to aspects connected with regulations concerning environmental protection. The systems generating thermal energy in the gas furnaces, coal, biomass, as well as the compression heat pumps with the lower heat source as ambient air or ground were taken under consideration, as well as centralized systems for the production of heat based on the combustion of coal, gas, oil, and biomass. the Emission of carbon dioxide for the installation of cogeneration and absorption heat pump were also calculated. Similarly obtained amount of extra emission necessary for the proper operation maintenance of heating devices via the supplied electricity from external source, the mostly fuel-fired power plants for fuels as previously mentioned. The results of the calculations were presented in tables and graphs.

In terms of climate forecasting, the Mediterranean region is among the most difficult. It is correlated with the five significant subtropical high pressure belts of the oceans and is symbolized by dry and hot summer and cold and rainy winter. Due to its location in the area, Albania is particularly susceptible to climatic changes. It has been noted that summertime sees the greatest temperature increases. More intense heat waves that stay longer and occur more frequently are anticipated in the eastern Mediterranean. The seasonal patterns of precipitation have not changed, but the amount of rain has become more intense. The effects of climate change have drawn attention to various renewable energy sources, including solar and wind power. In this study, the changes and prospective in average temperature, rainfall, humidity, CO2 emission and their impact in energy production were investigated. Several different models such as Auto Regressive Integrated Moving Average method; Prophet algorithm; Elastic-Net Regularized Generalized Linear Model; Random Forest Regression models; Prophet Boost algorithm; have been built for the study and prediction of each variable. The appropriate models are used to determine the anticipated values of the indicators for a period of four years. The prediction shows an increase in CO2 emission which leads to a decrease in energy production by hydropower. These findings suggest the use of other renewable sources for energy production in the country and the Mediterranean region.

Opis:
This study offers an overview of how changing habits in consuming a cup of tea can contribute to make better environment. As the initial existing scenario, survey for picturing Indonesian consumers in preparing their cup of tea from dried leaves was conducted to urban and suburban citizens. According to the survey, both respondent groups were using LPG as the first choice in boiling water for preparing tea, followed by using an electric dispenser as the second choice. This habit causes CO2 emission from processing a cup of tea by Indonesian consumer was 24 g CO2-eq per cup of tea, excluding the tea organic waste. The portion of CO2 emission from boiling water in tea preparation was 41.93% of whole CO2 emission from plantation to served cup. The emission can be significantly reduced by converting dried tea (initial scenario) into the ready-to-drink product, in the form of powdered tea (second scenario) and boxed tea (third scenario). This study simulated an integrated system of tea product manufacturing system with biogas utilization produced from tea organic waste. Simulation conducted based on daily manufacturing process at the Gamboeng green tea factory. Additional required energies were simulated from the wood pellet, which is the best practice in the Gamboeng Tea factory. By shifting tea consuming habit from dried tea to powdered tea and/or boxed tea, the emission from a cup of tea can be reduced, with range of reduction varied from 8.87 g to 22.13 g CO2-eq per cup of tea. If the Gamboeng green tea daily production capacity of the factory is fully converted into powdered tea, the potency of CO2 emission reduction reaches 26.92 metric ton CO2. However, the factory should pay attention to providing the water for the manufacturing process. The required water was 45.23 m3 of drinking water if all dried tea converted to powdered tea. Moreover, 11.53 m3 of water is required as irrigation for the biogas process in converting all tea organic waste into biogas.

Within the framework of quests of supplementary and „healthier” binders to the production of concrete followed the development of geopolymers in construction. However the practical application of these materials is still very limited. The production of each ton of cement introduces one ton of CO2 into the atmosphere. According to various estimations, the synthesis of geopolymers absorbs 2-3 times less energy than the Portland cement and causes a generation of 4-8 times less of CO2 a very high fire resistance and also a high resistance to UV radiation.
W ramach poszukiwania zastępczych i „zdrowszych” spoiw do produkcji betonu nastąpił rozwój geopolimerów w budownictwie. Jednakże praktyczne zastosowanie tych materiałów jest jeszcze nadal bardzo ograniczone. Produkcja każdej tony cementu wprowadza do atmosfery tonę CO2. Według różnych szacunków, synteza geopolimerów pochłania 2-3 razy mniej energii, niż cementu portlandzkiego oraz powoduje wydzielenie 4-8 razy mniejszej ilości CO2. Do tego betony geopolimerowe posiadają wysoką wytrzymałość na ściskanie, bardzo mały skurcz i małe pełzanie oraz dają wysoką odporność na korozję kwasową i siarczanową. Betony te są także odporne na korozję węglanową i posiadają bardzo wysoką odporność ogniową, a także wysoką odporność na promieniowanie UV.

Opis:
Vehicle operating fuel consumption estimation has a measurable significance for both individual users as well as transport and Communications companies. Complex analysis of the results may cause reduction of power (fuel) consumption, CO2 and toxic compounds emissions in exhaust gases. Operating fuel consumption estimation carried out by drivers' encounters basic difficulties connected with the lach of reliable reference standard for comparison of measured fuel consumption during car usage. Therefore it is necessary to identify vehicle operating conditions and ascribe them reference fuel consumption according to the accepted reference standard. A method of description ofreal vehicle operating conditions has been presented in this paper. Presented examples show that vehicle operating conditions may be unambiguously described with the use of proposed indicators. They can be also used to forecast the fuel consumption with high accuracy. Exclusive use of certification tests as model of operating conditions for this purpose does not allow keeping high conformity of assumptions with usage practice. Creation ofan individual map of operating conditions for a chosen agglomeration would enable to optimize choice of vehicle or fleet for an intended place of operation. Utilization of such operating conditions map may be: to determine reference fuel consumption for assumed operation area or optimal route of drive from the point of view of minimizing fuel consumption, energy or CO2 emission to the atmosphere. Selected examples of Utilization of such operating conditions map have been presented.
