Opis:: This paper discusses generally the possibility of reduction carbon dioxide and nitrogen oxides emissions from internal combustion engines of vehicles by using biomethane. The road transport in Europe almost fully depends on fossil fuels. Diversification of the road transport fuels will be a key attribute for road transport in the coming years. Purified biogas is one of alternative renewable fuels. Actually, in Poland biogas is used for generating electricity and heat. In some countries (for example in Sweden), upgraded biogas to natural gas quality (biomethane) is used as a vehicle fuel too. In this paper estimated biogas production potential in Baltic See Region countries: Poland and Sweden. It was one of the purposes of European Project Baltic Biogas Bus, and it is taken into account in European Project More Baltic Biogas Bus realized presently. Comparative studies of exhaust emissions of carbon dioxide and nitrogen oxides from city buses powered by diesel and CNG engine were carried out. The study was conducted under real traffic conditions in southern Polish city Rzeszow. Due to the lack in-service city buses with emission level Euro V in Rzeszow, comparative studies of this type of city buses powered by diesel and CNG engine was conducted in SORT I test. Determined mean values of road emissions of carbon dioxide and nitrogen oxides in g/km for the city buses operated in Rzeszow. Estimated value of the total road emissions in the case that would be replaced half the fleet of city buses (40 CNG buses and about 35% of the diesel engine powered buses, meet Euro III emission standard) by the CNG-powered (biomethane) city buses, complying with Euro V (EEV) emission standard.

Opis:: Depletion of fossil energy sources, and thus the prices increase of conventional fuels such as gasoline or diesel fuel, the energy security and dependence on imported fuels, as well as the deteriorating environment and global warming mean that there are more and more new technologies using renewable energy sources nowadays. In the medium- and long-term perspective a significant changes are needed regarding means of transport in ensuring "sustainable mobility", while the horizon of short-term solution is the implementation of biofuels, including biogas refined to form of biomethane, and renewable alternative fuels. Biomethane is produced from waste organic matter. Directive 2009/28/EC indicates the benefits of using waste for the production of transport fuels, to decarbonisation of the energy sector and requires Member States of UE to use renewable fuels. The paper presents possibilities for the biomethane production, as well as conditions to use it as fuel to power city buses. The level of current use of gaseous fuels in the national urban transport was specified, and also conducted an evaluation of benefits, especially ecological, to use these fuels for these applications.

Opis:: The development of societies building modern economies and production was and is associated with the continuous growth of energy consumption. Nowadays the world was forced to take a different look at the problem of energy consumption and fossil fuels. Because of cost of mining and production, unstable political situation in resource-rich countries and ecological perspective, many scientists seeks renewable energy sources, in quantity sufficient to meet the demand. Because of development of technologies obtaining many types of renewable energy sources that can be adapted to the needs of energy and the environment in which it will be received. Because of rich resources of ingredients that make production possible biogas, it is the most appropriate renewable fuel for agricultural infrastructure. The paper comprehensively describes factors influencing the development of renewable energy to their nature and technology in the application of renewable fuel gas with particular reference to methane gas and biomethane. There is general agreement on the Reed for sustainable biofuel industry, there is little understanding on how to avoid social and environmental degradation with global biofuel production. Results showed a variety of government policies, the most significant of which concerns agricultural production. In analyses the impact of government's policies on promotion of affordable, alternative energy sources capable of maintaining current energy consumption standards.

Opis:: The article presents the advantages of using biomethane to power city buses. Given the current possibilities for the production of biomethane in the country. They are very limited, but established the country's first mobile installation biogas purification to natural gas quality. Presented the results of comparative testing exhaust emissions and fuel consumption of city buses: CNG (biomethane) and diesel. The study was conducted in the national real traffic conditions. Reference was also the issue of eco - driving buses power CNG or biomethane. Presented used to test devices eco - driving Sagasystem company. The Sagasystem collects main information from the FMS gate in the vehicle: speed of the bus, fuel consumption, fuel consumption when in idle gear, work time when in idle gear, number of braking. Additional information from the FMS gate is the speed of vehicle (and individual wheels), speed of vehicle (according to the GPS), use of clutch (on/off) etc. Test results of emission standards and fuel consumption of CNG-powered bus (biomethane) in the national real traffic conditions were presented. Tests were carried out using and without the use of the above equipment.

Opis:: The article contains an analysis of the load of the engines that drive city vehicles for waste collection. These vehicles operate in specific conditions and perform unconventional tasks. For this reason, the engines run in conditions of part load at low speed. Access to places where biogas is produced and the specific engine load led the Authors to propose a new concept of fuelling of the engine, which is presented in the article. To drive a waste collection vehiclefor the Authors propose to use a spark ignition engine fuelled with dried biogas, which was purified from sulphur compounds and biomethane. In case of lack of biomethane, natur al gas could be used. The two fuels are supplied to the engine in proportions depending on the load, but because of the specificity of the analyzed vehicles tasks it is expected that a significant share of time the engine will be fuelled by biogas or biogas slightly mixed with biomethane or natural gas. A prototype engine fuelled with two fuels will be based on a diesel engine, which will be modified. Especially pistons andfuel system will be changed. The ignition system with high discharge energy will be also prepared. The proposed concept of the engine intended to be applied to the waste collection vehicle is a result of analysis of engine run conditions for this type ofoperation. In particular, the idea combines the running conditions of the engine and the access of the vehicle to the place where renewable fuel is produced.
