The crankshaft run-up process is a critical transient phase in internal combustion engine operation, during which the engine transitions from rest or low rotational speed to a stable operating condition. This process is governed by the interaction between combustion-generated torque, mechanical resistance, and the inertia of the rotating system. Accurate modelling of this phase is important for improving engine design, reducing experimental effort, and better understanding transient engine dynamics. This paper pre...

This paper presents a theoretical analysis of the application of artificial neural networks for modeling the run-up time of combustion engines. Engine run-up time is defined as the period required for the crankshaft rotational speed to increase from an initial state to a specified operating level. The process is influenced by numerous nonlinear physical and chemical phenomena, including fuel properties, combustion dynamics, mechanical inertia, and operating conditions. Due to the complexity of these interactions, ...

In recent years, there has been observed an intensive development of consumer unmanned aerial vehicles (UAV). Their advantage is a relatively low cost compared to typical aircraft constructions. The UAV equipment in recording devices allows them to be used for surveying, volumetric measurements, vegetation index calculations (including the normalized difference vegetation index) and thermovision analyzes. Due to the high resolution, the materials obtained from UAV can be a source of information, among others for d...

Machine building is one of the basic branches of the economy of Ukraine, the level of development of which is directly related to the environmental burden on the territory of individual regions. Snizhnyansky machine-building plant (SMP) is located in the Donetsk region. The enterprise is a part of the joint-stock company "Motor Sich" of Zaporizhzhya. The enterprise specializes in the manufacture of assemblies and parts for complete sets of aviation engine products in the shops of the main enterprise located in the...

Background. Reducing fuel consumption in the engine, while achieving assumed power is important for both reasons: the economic and the environmental. In this work series of studies of diesel fuel combustion in cogeneration system with the participation of 1:4000 vol. CeO2 concentrate: diesel oil was prepared. CeO2 concentrate purifies combustion chamber and afterburns hydrocarbons which in turn affects lowering the fuel consumption. Purpose is assessment of the impact of the possibility of adding Bluediesiel as a ...

Currently, new solutions in the field of alternative fuels are being sought after, taking into account the economic and the ecological aspects of their production. Due to the depleting resources of conventional fuels, one of the currently considered new research directions is the production of fuels derived from unconventional sources. This is due to the constantly increasing number of vehicles and growing traffic. It is noted that the consumption of gas oil is larger than that of gasoline. Therefore, potential fu...
