Opis:: The article characterizes state-of-the-art PEMS (Portable Emission Measurement System) equipment for exhaust emissions measurement under actual operating conditions. This equipment allows measurement of the exhaust emissions from all modes of transport. Besides, the article contains the results of exhaust emission research for engines of a variety of transport applications such as light duty vehicles and heavy-duty vehicles. Own exhaust emission research results performed under different traffic conditions of new motor vehicles fuelled with different fuels (gasoline, diesel fuel and natural gas) have been compared with the type approval values that define the vehicle emission indexes. The analysis has been performed in relation to a vehicle but the proposed measurement methodology is also knit to the engine operating conditions. The testing of heavy-duty vehicles described in the book was divided into several stages for which the results obtained for these vehicles were compared for loaded and unloaded vehicles. Ecological advantages of the city buses of different powertrain configurations have been determined (diesel, hybrid) on selected regular bus lines in city centre.

Opis:: Research work on the new assessment of environmental indicators using equipment from the PEMS group (Portable Emission Measurement Systems) with motor vehicles is being developed. Due to the miniaturization of equipment, there are new measurement possibilities for more and more numerous groups of vehicles, including two-wheelers. The article presents the research and a summary of the results of a moped equipped with a two-stroke engine, approved in accordance with the Euro 3 standard. The research object is mainly used for driving in urban traffic. Therefore, the research route was created as the first communication frame in the Poznań agglomeration. In the analysis of the results, the author’s M toxicity index was proposed, which is based on the assumption that CO2 emission is a measure of the correctness of the combustion process. The equipment from the PEMS-AxionR/S+ group, characterized by small dimensions and low weight, was used to determine the actual motion parameters and the emission of toxic compounds. In the analysis of the measurement results, dimensionless indicators of toxicity M of gaseous compounds were determined and a comparative analysis was made with the values of other objects obtained in the course of previous research (motorcycle, passenger car, off-road vehicle, hybrid bus and agricultural tractor). Due to the engine design (two-stroke type), the worst environmental indicators were obtained for CO and HC compared to other tested vehicles.

Opis:: The share of road transport accounts for more than 85% of the total structure of freight transportation. In this process, mainly motor vehicles are used to carry out the freight work. In addition to them, forklifts are also used, whose task is to load and unload goods. These vehicles are categorized as NRMM (Non-Road Mobile Machinery). Forklift trucks have internal combustion or electric drive. The paper presents an analysis of the emission of pollutants and fuel consumption from forklift trucks equipped with diesel and LPG power. The study uses the author's test taking into account the raising/lowering of a pallet, a loaded and unloaded run. The measurements were made in the warehouse and outside the warehouse using the Portable Emission Measurement System (PEMS) equipment. The aim was to show the influence of loading conditions on the emission of pollutants and fuel consumption.

Opis:: Artykuł przedstawia analizę wyników pomiarów emisji wybranych składników spalin w początkowym okresie pracy silnika spalinowego o zapłonie iskrowym wyposażonego w wielowtryskowy, pośredni system zasilania oraz w trójfunkcyjny konwerter katalityczny. Pomiary zostały wykonane dla dwóch stanów cieplnych silnika, tj. dla rozruchu zimnego, gdy silnik i wszystkie jego podzespoły oraz płyny eksploatacyjne posiadały jednakową temperaturę, równą temperaturze otoczenia, a także dla rozruchu gorącego, uzyskiwanego bezpośrednio po mającym miejsce wcześniej okresie pracy silnika w warunkach równowagi cieplnej. Odczyty wyników dokonywane były z krokiem jednosekundowym i mogą być przedstawiane w postaci przebiegów czasowych obrazujących charakter zmian emisji w obserwowanym okresie. Analiza emisji w aspekcie ekologicznym uwzględnia w szczególności porównanie oraz ocenę zimnego i gorącego rozruchu pod względem wielkości emisji szkodliwych składników spalin.
This article presents analysis of measurement results of combustion gases chosen components, obtained during initial phase of work of a spark ignition combustion engine, equipped with multi-point indirect injection system and three way catalytic converter, work. Measurements were conducted for two temperature states: for a cold start, when engine, all its components and exploitation liquids were of the same, equal to its surroundings, temperature, and for a hot start, which takes place right after proceeding it period of engine operation in conditions of thermal equilibrium. Readings were taken in one second intervals and can be presented as curves in function of time, showing character of emission changes in a given time. Analysis of emissions, with regard to its ecological aspects, embraces comparison and evaluation of the cold and hot start effect on amount of harmful substances emitted.

Opis:: The basic problem in terms of measuring exhaust emissions is the approval tests of traction vehicles, which are carried out on engine dynamometers. Therefore, it is impossible to obtain reliable results concerning their actual impact on the natural environment. It is therefore advisable to carry out the tests in real operation conditions, as is the case for road vehicles for which RDE (Real Driving Emissions) tests are carried out. The latest Stage V emission standards push for the introduction of this type of test, but no limit values for toxic exhaust gases have been established and no test guidelines have been defined for assessing actual emissions. This article describes the issues related to the legislative guidelines for non-road vehicles in force in Europe, as well as the measurement tools used, such as mobile equipment for measuring emissions of PEMS (Portable Emissions Measurement Systems) and newly developed emission gates. Additionally, the paper presents examples of locomotive exhaust emission tests in real operating conditions. The aim of the measurements was to assess the emission of toxic compounds against the relevant standards. The subject of the research was a diesel locomotive type T448.P equipped with a modernized internal combustion engine.
