“…Studies point to the fact that emissions can also be affected by the method of measurement. Skrúcaný et al proved this in research, when he monitored the fuel consumption of a road vehicle [49]. It is clear from the research that fuel consumption, as well as emission production, were different when measured in the laboratory and in real driving.…”

The preparation of the fuel mixture of a conventional internal combustion engine is currently controlled exclusively electronically. In order for the electrical management of an internal combustion engine to function properly, it is necessary that all its electronic components work flawlessly and fulfill their role. Failure of these electronic components can cause incorrect fuel mixture preparation and also affect driving safety. Due to the effect of individual failures, it has a negative impact on road safety and also negatively affects other participants. The task of the research is to investigate the effect of the failure of electronic engine components on the selected operating characteristics of a vehicle. The purpose of this article is to specify the extent to which a failure of an electronic engine component may affect the operation of a road vehicle. Eight failures of electronic systems (sensors and actuators) were simulated on a specific vehicle, with a petrol internal combustion engine. Measurements were performed in laboratory conditions, the purpose of which was to quantify the change in the operating characteristics of the vehicle between the faulty and fault-free state. The vehicle performance parameters and the production of selected exhaust emission components were determined for selected vehicle operating characteristics. The results show that in the normal operation of vehicles, there are situations where a failure in the electronic system of the engine has a significant impact on its operating characteristics and, at the same time, some of these failures are not identifiable by the vehicle operator. The findings of the publication can be used in the drafting of legislation, in the field of production and operation of road vehicles, and also in the mathematical modeling of the production of gaseous emissions by road transport.

The automotive sector has recently undergone enormous transformations, mainly dictated by the requirements to reduce the negative impact of the automotive industry on the natural environment. Reducing emissions from this sector has become the main driver of change in modern motor vehicles. Unfortunately, due to economic differences in the world, this process is not the same in all countries. Despite these differences, however, even in less developed countries, efforts are made to reduce vehicle exhaust emissions. The work conducted road tests, bench, calculated comparative studies of fuel, economic, environmental and energy performance of a serial car with a standard carburetor power system and equipped with an electronic gasoline injection system and a three-component catalytic converter under operating conditions.

“…Motor oil is important for maintaining optimum engine performance [1,2], reducing fuel consumption [3][4][5] and emissions [6]. During its operation in the engine, it is exposed to considerable oxidation, high temperature, pressure and the penetration of unwanted contaminants from external environment.…”

Viscosity is considered to be a key factor in the quality of lubrication by oil and engine manufacturers and is therefore one of the most monitored parameters of lubricants. FTIR (Fourier-transform infrared) spectrometry in combination with Partial Least Squares (PLS) and Principal Component Regression (PCR) was therefore proposed and tested as an alternative to the standardized method for determining the kinematic viscosity at 100 °C with an Ubbelohde capillary viscometer (CSN EN ISO 3104) of worn-out motor oil grade SAE 15W-40. The FTIR-PLS model in the spectral region of 1750–650 cm−1 with modification of the spectra by the second derivative proved to be the most suitable. A significant dependence of R = 0.95 was achieved between the viscosity values of 190 samples of worn-out motor oils, which were determined by a standardized laboratory method, and the values predicted by the FTIR-PLS model. The Root Mean Square Error of Calibration (RMSEC) parameter reached 0.148 mm2s−1 and the Root Mean Square Error of Prediction (RMSEP) parameter reached 0.190 mm2s−1. The proposed method for determining the kinematic viscosity at 100 °C by the FTIR-PLS model is faster compared to the determination according to the CSN EN ISO 3104 standard, requires a smaller amount of oil sample for analysis and produces less waste chemicals.
