TL;DR: Combined simulation and analytical analysis enables deep insight into the energy conversion phenomena in hybrid powertrains and reveals the advantages and disadvantages of both hybrid concepts running under different operating conditions.

TL;DR: In this paper, a combined analytical and simulation approach was applied to analyze energy conversion efficiency of different hybrid electric vehicles (HEVs) topologies, power ratios of their components and applied control strategy.

TL;DR: In this article, an asynchronous electric motor with a very thin rotor was applied to support the turbocharger during the transient operation of an automotive diesel engine, and the experimental work of matching an electric motor to an engine is rather expensive; it was therefore decided to determine general characteristic of the electric motor separately through experiments, whereas transient response of the turbocharged and intercooled diesel engine was simulated by a zero-dimensional filling and emptying computer simulation method.

TL;DR: In this paper, a new criterion for the determination of the start of combustion (SOC) from the diesel engine in-cylinder pressure diagram was developed, defined as the maximum of the third-order derivative of the cylinder pressure with respect to the crank angle.

TL;DR: In this paper, an analysis of the interaction between a turbocharged diesel engine operating under various load conditions and electric assisting systems, as well as the requirements for supporting electric motors suitable for the improvement of an engine's dynamic response is presented.
