    Opis:
    Power of any kind of a car engine is considered to be one of the basic factors in order to choose or assess vehicles equipment or its appropriateness. It influences several operation properties including car maximum velocity, car acceleration, etc. A car producer shall issue the data about an engine power of a car in a form of its technical attributes, nevertheless an engine power specification is also stated in a car registration certificate. Engine power may be defined as the maximum engine output at given revolutions of an engine, i.e. maximum engine power. In most of cases of cars operation, various situations may occur in order to specify the maximum engine power value. This study addresses the issue of determining individual factors affecting the engine power while a passenger car in operation, i.e. testing the engine power on the single roller bench and related particular analysis.

    Opis:
    The aim of the article is to present the environmental effects of changes in material composition in selected internal combustion engines used in passenger cars using LCA analysis. The levels of energy consumption and emissions of pollutants related to material inputs occurring at the stage of engine production have been determined. The simplified LCA model presented in the paper shows the energy consumption and total CO2 and SO2 emissions on the basis of the mass of materials from which the engine is made. The research results presented in the paper give a picture of a modern passenger car engine on the basis of wear and the degree of recovery of materials used for its construction.

    Opis:
    Jednym z największych niekorzystnych skutków rozwoju cywilizacji jest hałas. Można się z nim spotkać wszędzie, a szczególnie w mocno zurbanizowanych zakątkach świata. Do jednego z największych źródeł hałasu należy ruch drogowy. Chcąc chronić człowieka przed skutkami hałasu komunikacyjnego, opracowano szereg wytycznych jakie musi spełnić pojazd, aby móc się poruszać po drogach. W artykule sprawdzono jaki poziom hałasu we wnętrzu samochodu osobowego działa na kierowcę i pasażera na postoju przy uruchomionym silniku oraz w trakcie jazdy.
    One of the biggest negative impacts of a civilization is noise. It can be found everywhere, especially in highly urbanized parts of the world. One of the largest sources of noise is traffic. In order to protect human beings against the effects of traffic noise, it was developed a set of guidelines that must be met by the vehicle to be able to navigate the roads. In this article was checked how the noise level inside the car works on the driver and passenger at a standstill with the engine running and while driving.

    Opis:
    A significant reduction of CO2 emission in the road transport is a major challenge for next years. In the combination with efficient powertrain technologies, the potential of natural gas is excellent for comparably light and cost effective reduction of CO2 and toxic emission in the future [1-2]. As the CNG fuelling stations in Poland are not so far widespread enough to make a dedicated natural gas vehicle practical, it results necessary to start with proposing alternatively CNG powered engines. Such a bi-fuel automotive engines are necessary to bridge the gap between petrol and natural gas. As a sample of modern engine design an Opel 1.6 litre 4-cylinder engine has been selected as a base of powertrain for development of bi-fuelpassenger car engine. The influence of ignition timing on CNG combustion process has been presented in this paper. A 1.6 litre SI engine has been tested in the special program. For selected engine operating conditions, following data were acquired: in cylinder pressure, crank angle, fuel mass consumption and exhaust gases temperatures. For the settings of 6, 9, 12 and 15 deg crank angle timing advance correction, the internal temperature of combustion chamber has been estimated, as well as the charge combustion ratio and ratio of heat release were tested. With the help of the mathematical model, emissions of NO, CO and CO2 were additionally estimated. Obtained results made it possible to compare the influence of ignition timing advance on natural gas combustion in SI engine.

    Opis:
    The influence of hydrogen-methane blends application in SI engines on their CO2 emission is the main goal of this paper. The 1.6 litre engine alternatively fed with either petrol, CNG and with methane-hydrogen blends has been tested in the research program. The possibility of passenger car engine operation on H2-CH4 mixtures has been demonstrated in the paper, with the underlining of the potential of those mixtures in the increasing of the engine efficiency. Necessary changes in strategy of engine regulation, especially in air/fuel ratio, ignition advance and EGR rate, were noticed and prepared. The methane-hydrogen blends, which were used in the research programme featured ratios as follows: 5%, 10% and 15% of hydrogen. For selected engine operating points, following data has been acquired: in cylinder pressure variation, crank angle, manifold pressure and finally mass fuel consumption. On the basis of registered data for all fuels - burned temperature in cylinder has been estimated, as well as the charge combustion ratio, and the heat release rate. With help of mathematical model describing the exhaust gases formation it has been possible to estimate the NO, CO and CO2 emission level. Obtained results made it possible to compare the combustion process for all tested fuels and pointed on the significant influence of hydrogen percentage for the methane-hydrogen blends, on the CO2 emission reduction up to 20%. Negative aspects of chosen blends application have been also describe in the paper, especially of increasing engine thermal load.

    Opis:
    Transport is one of the most burdensome negative sources affecting the natural environment. Long-term exposure of the body to exhaust pollution can cause health problems and, in the worst case, even lead to death. In addition to exhaust emissions, traffic noise is another equally important issue. Due to its nature, variability over time or the design diversity of vehicles in the traffic flow, it is a phenomenon difficult to define. Like exhaust pollution, it affects people's health and quality of life. In addition to its direct impact on the human physical system, it can also cause psychosomatic disorders, which is why a detailed analysis of road noise taking into account the real operation of the vehicle is so important. The paper presents the basic concepts related to the problem of traffic noise in the world, determines the sources of noise in vehicles and the methodology of conducting acoustic road tests. At the final stage of the scientific paper, methods of reducing excessive noise levels in large urban agglomerations were also presented, and the effectiveness of using noise barriers on selected parts of the city road network using proprietary acoustic tests was assessed.
