mixtures realizes the function of the combustion process activator. Thus, hydrogen addition improves energy conversion by about 3%. The second group of fuels is constituted by LPG and DME mixtures. DME mixes perfectly with LPG, and differently than other hydrocarbon fuels, consisting of oxygen as well, which makes the stoichiometric mixture less oxygen demanding. In the case of this fuel an improvement in engine volumetric and overall engine efficiency has been noticed compared with LPG. For the 11

ENERGY CONSUMPTION AND CARBON FOOTPRINT OF AN ELECTRIC VEHICLE AND A VEHICLE WITH AN INTERNAL COMBUSTION ENGINE

The use of electrically powered vehicles is becoming more and more established in practice and represents a promising solution in future ensuring quality mobility and reducing the pollution in the environment. Since these vehicles are high-priced, and there is still a low awareness among consumers in terms of energy consumption and pollution, vehicles with an internal combustion engine remain the norm. For this purpose, the study, here, provides an energy consumption estimate of an electric

Interaction of Gram-Positive and Gram-Negative Bacteria with Ceramic Nanomaterials Obtained by Combustion Synthesis – Adsorption and Cytotoxicity Studies

This paper presents the interactions of Gram-positive (Staphylococcus aureus) and Gram-negative (Pseudomonas putida) bacteria with ceramic materials obtained by combustion synthesis. These studies were conducted based on an analysis of the adsorption of bacteria onto aggregates of ceramic materials in an aqueous suspension. The materials used in the studies were of a nanostructured nature and consisted mainly of carbides: silicon carbide (SiC) in the form of nanofibers (NFs) and nanorods (NRs

NANOSTRUCTURED ZnCo2O4THICK FILM AS AN ETHANOL SENSOR

Semiconductive nanometer-size material ZnCo2O4 was synthesized by a solution combustion reaction of inorganic reagents of Zn(NO3)3. 6H2O, Co(NO3)3.6H2O and glycine as a fuel. The process was a convenient, environment friendly, inexpensive and efficient preparation method for the ZnCo2O4 nanomaterial. The synthesized materials were characterized by TG/DTA, XRD, EDX, SEM, and TEM. Conductance responses of the nanocrystalline ZnCo2O4 thick film were measured by exposing the film to reducing gases

COMPARATIVE LIFE CYCLE IMPACT ASSESSMENT OF CHOSEN PASSENGER CARS WITH INTERNAL COMBUSTION ENGINES

The purpose of this paper is to provide a comparative environmental life cycle assessment (LCA) of chosen internal combustion engine vehicles (ICEVs). It addresses an LCA of both petrol-fuelled and diesel-fuelled passenger cars. The analyses pertained to the carbon footprint and respiratory inorganics related to the cars in question, considered against the relevant system from cradle to grave. The comparative analysis has shown that the carbon footprint of a diesel-fuelled car is lower than

An attractive option in counteracting the effects of the emission of internal combustion engines is alternative gas fuels, including biogas, natural gas, dimethyl ether (DME), hydrogen (H2), and mixtures of them. This article focuses on mixtures that are easy to obtain: natural gas and hydrogen (HCNG) and petroleum gases with dimethyl ether (LPG and DME). Their impact on engine performance, combustion

Main conditions and effectiveness of gas fuel use for powering of dual fuel IC self-ignition engine

Internal combustion engines are fuelled mostly with liquid fuels (gasoline, diesel). Nowadays the gaseous fuels are applied as driving fuel of combustion engines. In case of spark ignition engines the liquid fuel (petrol) can be totally replaced by the gas fuels. This possibility in case of compression engines is essentially restricted through the higher self-ignition temperatures of the combustible gases in comparison to classical die-sel oil. Solution if this problem can be achieved by using

THE IMPACT OF CHANGING THE FUEL DOSE ON CHOSEN PARAMETERS OF THE DIESEL ENGINE START-UP PROCESS

For internal combustion engines, many faults relating to the combustion process can occur, which affect the engine technical condition, its electrical equipment, the natural environment, etc. This article presents the results of the influence of the regulatory factor, which was the fuel dose (3 dose values), on selected parameters of the start-up process at constant settings of other control parameters (fuel injection advance angle and injection pressure). The tests of the start-up process were

DYNAMIC REGULATION OF THE PERCENTAGE COMPOSITION OF THE MIX DIESEL AND BIODIESEL FUEL

The use of internal combustion engines increase environmental pollution and dependence on fossil fuels. The biodiesel fuel, which is renewable, more environment friendly, and cheaper, is a good alternative for diesel engines. The use of biodiesel fuel leads to a drop in diesel power and an increase in fuel consumption. To prevent these shortcomings, it is proposed to use dynamic regulation of the percentage composition of a mixture of diesel and biodiesel fuel. The modernization of diesel

The main issues due to the high concentrations of H2 S in biogas are its corrosive action, which damages engines and the production of sulfur oxides (SOx ) due to H2 S combustion. The best ways to remove H2 S from biogas are the biological methods with the use of biofilters, biotrickling filters, bioscrubbers and using of activated sludge.
