Original Abstract

The right choice of power train layout is a key prerequisite for success in the chosen market. However, the operating conditions and driving modes of passenger vehicle power trains differ in different markets. The paper presents a study of the influence of the layout and other design modifications of the crank train of an in-line spark-ignition engine on the running smoothness at atypically low engine speeds and high engine load. Several design proposals of the crank train are assessed from this point of view and compared based on the results of dynamics simulations using a discrete torsional model with lumped masses which is solved in the frequency domain.
