Opis:: This article reports the results of a study into operating parameters of a system consisting of an SI engine and a powertrain in a Fiat Panda passenger car in the conditions of a variable load. The analysis was primarily concerned with the variability of fuel consumption resulting of the changing load applied to the driving wheels in the conditions of a test performed on chassis dynamometer for manual and automatic controlled transmission gear change The test bench included a dedicated driving cycle, which was developed as cycle with periodically changed constant linear speed of the car every 10 km/h. According to the vehicle set speed, the load on its wheels was determined by the basic resistance as rolling resistance, air resistance and resistance corresponding to road inclination. Each period of a drive cycle corresponding to steady state driving gave the average instantaneous values of drive system performance indicators. The waveforms of these indicators were recorded and then averaged and presented as representative points of the powertrain system that were analysed. The focus of the study involved the identification of the points characterized with the minimum specific fuel consumption and impact of type of powertrain control on emission of CO2 from passenger car SI engines.

Opis:: This article reports the results of experimental and numerical analysis of emissions of nitrogen oxides in exhaust gas to the environment from a turbocharged diesel engine of a tractor. The problem of identifying nitrogen oxides emissions from the exhaust gases was formulated and subsequently solved, based on data gained from measurements. The results of estimation of nitrogen oxides emissions were verified on the basis of research on a test object. The object of the study and a non-linear static model of nitrogen oxides emission were also described for two systems – with and without exhaust gas recirculation. The article demonstrates that the use of an adequately selected mathematical model can lead to the estimation of emissions of nitrogen oxides contained in the exhaust gas of diesel engines in an off-road vehicle. The created model can be used to control the valve of the exhaust gas of recirculation system and so reduce the emission of harmful substances to the environment. The presented research results show the comparison of estimated and measured nitrogen oxides concentration. The estimated value from the mathematical model concentration is about from 0.7 s to 1 s earlier than the value measured by the sensor, therefore the exhaust gas recirculation system could be controlled accordingly before nitrogen oxides are formed.

Opis:: This article describes the method of controlling an electric magnetic linear actuator that moves an inlet valve of an internal combustion engine. Thanks to the use of the electric control of the inlet valve of the internal combustion engine, it was possible to implement a variable effective compression ratio of the operating power unit, adapting it to the current needs and engine load. In this design, valvetrain was modified by introducing an autonomous intake valve operation with the use of a specially designed electromagnetic actuator. The introduction of this system necessitated an additional modification of the intake camshaft. The control was carried out with the use of a real-time controller with a built-in FPGA unit. The proposed design of a system with an electromagnetic actuator will allow obtaining an additional degree of freedom in the control unit. Particular attention should be paid to registered values or air pressure in the intake stroke for a closed or partially opened throttle, which generates significant pumping losses. The use of an electromagnetic actuator in the intake can help reduce said losses.

Opis:: An attempt has been made to clarify the effect of wide-ranging control of the exhaust gas recirculation system on the cylinder pressure and ecological engine performance. This publication contains the results of tests performed on the CI (compression ignition) engine of the off-road vehicle mounted on the test bench. The study was based on advanced EGR control with a proportional valve and a very efficient exhaust gases cooling system. Analysis of the test results is based on the cylinder pressure and the concentration of NOx and PM components at exhaust gases. The study included the influence of the exhaust gas recirculation system control on parameters such as differential pressure, MBF, and relative NOx and PM emissions. As demonstrated by the analysis conducted, the EGR valve control method and the exhaust gas cooling intensity significantly affect the cylinder pressure and its ecological performance.
