The paper includes a brief description of the methodology of obtaining dynamic characteristics of four basic exhaust gas emissions: CO2, CO, HC and NOx based on combined data from road tests on the engine test beds NEDC and FTP-75. The characteristics developed through tests on a class C motor-car have been presented. The possible advantages thanks to the application of the dynamic characteristics developed have been indicated. The significant values of emission during engine braking have been pointed out. For a wider recognition of this area of dynamic characteristics, special chassis tests were carried out on the engine test bed, recording the emissions of the exhaust gas components listed in the modal system with 0.4 s rate in the test of full engine braking on III, IV and V gear. The results were summarized and assessed.

One of the basic purposes of passenger vehicle engine tests on a chassis dynamometer is to verify the results of the tests carried out on engine test beds in terms of the ECU parameters. The paper presents the analysis of the engine load distribution in driving cycles both European and American. The issue of the influence of selected calibrations of a 1.3 Multijet engine on its operating parameters and the exhaust emissions has been presented. The realization of the project consisted in performing a series of tests on a chassis dynamometer for selected ECU calibrations determined during the engine test bed phase.

Abstract The aim of the paper is to analyze and evaluate the basic parameters of the combustion process in a modern Fiat 1.3 Multijet diesel engine, fuelled esters (FAME) and diesel oil. During the tests on an engine test bed, the pressure waveforms in the cylinder were measured, on the basis of which the averaged actual indicator graphs were established in the determined engine operating conditions. On their basis, the pressure increase rates were determined and heat release characteristics were prepared based on the equation of the first principle of thermodynamics. The characteristics of the relative amount of heat released and the characteristics of the relative heat release rate were determined. The use of rapeseed methyl esters to supply the engine had an impact on the parameters of the combustion process as compared to its supply with diesel oil. Differences in the waveforms of heat release characteristics of the engine powered by the tested fuels are significantly greater at low loads. At the lowest engine loads, esters burn much faster than diesel oil. With the increase in engine load, the differences in the waveform of heat release characteristics during combustion of these fuels were significantly smaller.

Thermal analysis of a DC motor cooling system and description of measurement system applied to an engine test stand are the main topics of the paper. The motor that is being tested comes from the electric vehicle of Silesian Greenpower project whose aim is to design and build energy efficient bolids in order to participate in international races in Great Britain. During the designing process of the car, minimizing energy losses and maximizing powertrain efficiency are the main aspects taken into consideration. One of the crucial issues to accomplish these goals is to maintain optimal performance of the motor by applying effective cooling. The engine test stand used in this research was designed especially for Silesian Greenpower vehicles. Thanks to its modular construction and versatility, it enables measuring many different parameters of the motor and powertrain. In this paper the thermal analysis is described as well as how the measuring system of the engine stand works. The thermal analysis described in the article occurred to be very helpful in improving the cooling system and motor performance in the same time. The advanced measuring and control system of the test stand enables conducting versatile analysis of the DC motor and the powertrain.

This paper addresses the issue of metrological accuracy of instantaneous in-cylinder pressure measurement in a diesel engine test bed. In studies, the central unit has been the single-cylinder AVL 5402 engine. The pressure measurement was performed with a sensor designed for thermodynamic analysis, and the results were related to the crank angle, where two rotations corresponding to the four-stroke working cycle were denoted as angles between −360° and +360°. The novelty of this paper is the proposition of how to perform a type A uncertainty estimation of the in-cylinder pressure measurement and to assess its repeatability. It was demonstrated that repeatability of the measurement during the ignition process was difficult to estimate because of the phenomena that cannot ensure the repeatability conditions. To solve the problem, two methods were proposed. In one method, the pressure was measured in the subsequent cycles immediately after the ignition was turned off, and in another method, the engine was driven by a starter. The latter method provided maximal pressure values much lower than during usual tests. The obtained repeatability of measured pressure was %EV = 0.4%, which proved high capability of the evaluated measurement system.
