Opis:
Nowadays, the desire and the emphasis, which are put on continuous development, drive the innovative ideas all over the word. As an effect, the concept of Smart City was created. This term refers to the cities where logistics and public means of transport are crucial. One of the pioneering ideas implemented in Smart City is the possibility of renting a vehicle for minutes. This solution is proposed mainly in the big metropolises, and thanks to the development of Internet of Things, it has recently gained huge popularity. Among the offered vehicles, there are not only classic, ordinary passenger cars, but also the alternative means of transport such as: electric scooters, bicycles and delivery vehicles. In the context of the implementation of Smart City, Katowice decided to allow the transport-sharing companies to introduce their services within Silesia Province. The following project studies the competitiveness of transport-sharing enterprises’ services. The final conclusion shows that the variety of different transport-sharing companies’ proposals give customers the opportunity to choose the most appropriate and economical option for them in a particular moment.

Opis:
Reaching of high parameters of a drive unit and low pollution of the natural environment is considered to be the most desired effect of motorization. The use of the additive in the form of fatty acid methyl esters to the diesel oil, assumes lowering of harmful fuel gases’ emission and reaching high operating parameters of an engine, such as power and turning moment. Studies on the power output and the turning moment of an engine with self-ignition are presented in the study. The subject matter of the studies was a combustion engine with self-ignition of the power of 80 kW with the direct common rail system and turbo-compressor’s supercharging and with electromagnetic injectors. The tested engine was powered with diesel oil and the mixture of fatty acid methyl esters and the diesel fuel, in proportions 10%, 30% and 50% with an improver, at the standard settings of the fuel injection controllers. The vehicle used for the testing purposes, has been singled out with respect to the specific features, such as: universality of its use as a means of transportation and the opportunity of modification of the injection parameters, resistance to possible unfavourable consequences resulting from the use of the fuel mixture. The studies were conducted on a chassis test house, at full engine’s loading. The vehicle placed on the test house’s rollers, was strapped with belts to the foundation, and then accelerated up to the specific speed and subjected to loading standing in place. In such a manner, the road conditions were simulated. The obtained results of the tests were subject to the statistical analysis. From their analysis it results, that application of the mixture lowers the engine’s parameters to a degree unnoticeable at the time of its operation.
