Opis:: Due to the ending stocks of fossil fuels, as well as instability of the political situation in the world, especially in countries that are major crude oil suppliers, governments of countries poor in the resources are forced to seek alternative sources of energy. Currently, the most common fuel for admission of internal combustion engines is oil. As a result of the continuous increasement of fuels prices and legislation imposing decrease of toxic exhaust gasses emissions tends to expansion the power base of the automotive industry through the introduction of alternative fuels. One of them is fuels derived from renewable energy sources. These include gaseous fuels like biogas, hydrogen, and its mixtures. The presented paper includes description of Brown gas generator and verification of the desirability of enrichment in hydrogen and oxygen gaseous fuels used to supply internal combustion engines. The connection scheme of Brown gas generator for the engine is also presented. Division of alternative fuels used to power internal combustion engines, diagram of connection generator to the engine when the gas is feed to inlet manifold, Diagram ofpower supply system of gas generator, are also presented in the paper.

Opis:: The development of human civilisation has always been related to an increase in energy demand. The growth of transportation and an increase in the number of automobile vehicles in service produce a rising demand for fuel. Before piston IC engine is replaced with a different effective power source, it is necessary to use gaseous fuels on a larger scale than ever before. The natural resources of gaseous fuels are estimated to be much higher than crude oil reserves. Additionally, engines can run on biogas, i.e. gaseous renewable fuel. The use of gaseous fuels means lowering the harmful effect engines produce on the natural environment. Multi-fuelling, i.e. switching from one fuel to another, could be an advantageous feature of automobile combustion engine, both from the user’s standpoint and with respect to environmental concerns. Gaseous fuels have desirable properties that are especially suitable for fuel of spark ignition engines. The paper presents the engine test bench constructed at the Laboratory of Heat Engines of the Kielce University of Technology. The test stand comprises modern spark ignition engine Fiat 0.9 MultiAir and the eddy-current brake. At the test stand, the engine was converted to fuelling with three fuels, namely petrol, LPG gas blends and compressed natural gas (CNG). The engine could run alternatively on the three fuels mentioned above. The stand is equipped with an external unit to control the engine work, which makes it possible to extend the range of the engine investigations.

Tematy:: transport

Opis:: The aim of the research is to test the fuel additives which decrease dimensions of atomised fuel drops, by applying changes to the specific parameters which impact the atomisation process. Those parameters include density, surface tension, viscosity and the viscosity index. Dimensions of drops of biofuels are much bigger compared to hydrocarbon fuels. By modifying the physical and chemical parameters of biofuels, dimensions of drops in an atomised fuel stream should become smaller. Those dimensions play a major role for the level of emissions of hydrocarbon and carbon monoxide, as well as mainly nitrogen oxides and particulates. The research on emissions of toxic components of fuel is relatively advanced today in the field of piston combustion engines, especially for use in car vehicles. However, the dynamic development of the air transport brings more pressure on the issue of toxic emissions in the case of aircraft engines. The level of toxic emissions from aircraft engines may be from ten up to even several thousand times greater than the level of emissions from piston engines. The issue of how biofuel additives can affect the process of fuel atomisation and thus enable the control over the atomisation to obtain the smallest possible drops leading to reduced nitrogen oxides emissions is a new and original issue. The reduced nitrogen oxides emissions in the case of biofuels is of utmost significance because, according to latest knowledge, those levels are increasing.

Opis:: There has been observed for several years a number of attempts to introduce for everyday use small power units which utilize turbine engine as propulsion unit (the U.S., Japan, and Europe). Efficiency increase of such devices is achieved by improving of turbine engine design as well as utilizing of exhaust gas thermal energy to heat the compressed air supplied to combustion chamber and, for example to heat usable water. Significant orientation of turbine engine improvements lead to the modernization of combustion processes by applying of gaseous fuels (such as compressed natural gas) or implementation of high-temperature catalytic combustion. The purpose of these changes reduction of hydrocarbons, carbon monoxide and nitrogen oxides emissions. In Propulsion Department of Aviation Institute a scientific project has been realized, in which the object of study was aircraft turbine engine powered by a liquid propane-butane mixture. The paper presents some results of engine tests carried out, especially concerning feeding system, special fuel system applied LPG pumping systems with the use of sliding-vane pump and by means of pressure reservoir and combustion process of LPG atomized with the use of original GTD-350 vortex injector, adapted for aviation kerosene Jet-A.

Opis:: The contemporary progress of automotive industry and transportation is determined to a large extent by the increasing environmental requirements, aimed at limiting the harmful impact of vehicles upon human life and people’s health. A crucial issue linked with operating vehicles is the exhaust gases generated by internal combustion engines. In order to reduce this hazardous impact upon the natural environment, the construction of the engines is continuously improved, electronic controlling is being developed for managing the course of working processes taking place in cylinders and auxiliary systems, exhaust gases cleaning systems are being developed, alternative fuels are being sought for and the possibilities of their optimal use are being examined. Natural gas is the fuel that is highly expected and hoped to be used more widely for powering internal combustion engines in vehicles. This article presents the values of selected ecological indicators of the Perkins 1104D-E44TA Diesel engine, powered by compressed natural gas and Diesel fuel (CNG + ON). For comparison reasons, the engine was powered with both fuels at the same time and then only by Diesel fuel (ON) in the same working conditions. Before the tests, the powering system control unit had been calibrated so as to enable obtaining similar values of torque while the engine was powered with the Diesel fuel only and with both CNG and ON while working with external speed characteristics; the calibration was also set up to allow for the maximum share of the natural gas in the total fuel amount supplied into the engine cylinders without engine knocking. When powering the engine with both CNG and Diesel fuel, the concentration levels of nitric oxides and carbon dioxide in exhaust gases were lower. However, the total content of hydrocarbons in the exhaust gases grew multiple times, and the content of the carbon monoxide was significantly increased. In addition, the obtained measurement results of the smokiness of the exhaust gases and the content of the soot with the engine powered with two fuels were not satisfactory.

Opis:: This publication presents the possibility of using gaseous alternative fuels, in particular based on methane, such as Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG) or agricultural biogas and hydrogen, which gain in popularity as fuels for engines used in the automotive industry, in the segment of both passenger cars and trucks. Increasing efforts to reduce emissions of carbon dioxide (CO2), carbon monoxide (CO), oxides of nitrogen (NOx) and particulate matter into the atmosphere have been supported by legal environment shaped both at European Union level and in international regulations and translate into the growing importance of alternative gaseous fuels. This publication will present, among other things, the essential elements of "Clean energy for Transport", and "type approval of motor vehicles with respect to emissions” directives and of the Kyoto 1997 Climate Change Conference. It also demonstrates potential economic benefits of replacing traditional fuels with alternatives gas fuels. Cities of Tychy and Gdynia, which implement environmentally friendly solutions for public transport services, will serve as an example. The publication also recognizes direct environmental benefits arising from the replacement of currently used fuels – gasoline and diesel – with natural gas and fuels derived from renewable energy sources. In particular, the following publication deals with the use of gases, which are a by-product of human activity – gases from animal breeding and coal, mine methane drainage.
