Opis:
Both the light- and heavy-duty sectors of the automotive industry are currently under unprecedented pressure from a wide range of factors, particularly in terms of environmental performance and fuel consumption. Test procedures have undergone massive changes and continue to evolve, meaning that standards are becoming much harder to meet, especially in Europe but also in other continents. Such developments force changes in testing methodology, the development of powertrains themselves and their aftertreatment systems and strategies and calibrations. This paper reports and summarises the topics of the PTNSS Congress and attempts a synthesis on the current status of the field of LD ad HD IC engines, hybrid powertrains and electric vehicles, engine fuel and oil and what the coming years may hold for the automotive and fuel industries and other allied fields.

Opis:
Torsional vibration of crankshaft is a harmful phenomenon in every type of engine. It can easily cause a fatigue failure in engines with relatively long crankshafts and big bore diameters (usually above 90 mm). For these types of engines, the resonance caused by specific low order harmonic of gas force and inertia force of oscillating masses occurs in engine speed range, thus resonant torsional moment of big amplitude is generated. This moment, additionally acting on crankshaft, is harmful and can easily cause its fatigue failure. In order to reduce the resonance effects, the torsional vibration damper (TVD) has to be used. That is the reason why application of torsional vibration dampers is almost a rule in these types of engines. The viscose TVD is the most popular type of vibration damper in heavy duty diesel engine. Moment of inertia of its plunger is the main criterion of damper selection. It is the basic factor, which determines the amount of dissipation work, decreasing the additional torsional moment caused by resonance. Increasing plunger's moment of inertia induce the rise of dissipation work but simultaneously decrease natural frequencies of a crank train, what allows to resonate with low order harmonic of tangential force acting on crankpin. The paper concerns an analysis of influence of viscose TVD parameters on crankshaft's torsional vibration for six cylinder inline heavy duty diesel engine.
