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, ...
