Апстракт:
Internal combustion engine, as a cyclical energy machine, produces a variable effective torque as well as crankshaft speed consequently. Various factors have a major role on instantaneous value of effective engine torque, such as speed and load regime, number of cylinders and the cylinder arrangement (in-line engine, V engine etc.). Given these facts, as well as variable external engine loads, the crankshaft speed is variable even in the case of steady state operation regime. A higher coefficient of crankshaft speed non-uniformity causes, as a side effect, instability in the engine control system and increase vibrations transmitted to the vehicle and the passengers themselves. Therefore, in order to avoid these side effects, flywheel is used, leading to reduction of speed non-uniformity to reasonable and acceptable level. In this paper, an analysis of non-uniformity of engine speed without flywheel being attached on crankshaft is carried out. On the basis of the obtained results and recommendations for coefficient of speed non-uniformity, selection of appropriate characteristics of flywheel is carried out
