“…Advantages of CI engines include no-knock limit, low cycle-by-cycle volatility at lean conditions, and reduced pumping losses owing to unthrottled operation, resulting in extremely high efficiency as compared to SI engines. Previous works [56][57][58] provide a thorough examination of how engine design and operational characteristics affect diesel engine efficiency.…”

The transport of people, as well as cargo, has evolved and grown tremendously over the recent years. Technological development had to be adapted to the different government measures for controlling polluting emissions. Since the Paris agreement in 2015 limits have also been imposed on the CO2 emissions from road vehicles to keep global temperature growth below 1.5 o C. For the heavy transport sector, fleet limits of 15% for 2025 and 30% for 2030 CO2 reduction have been introduced with respect to the limits of 2019. Therefore, the current restriction of very low levels of polluting emissions, as well as greenhouse gases, makes the transport sector face a great technological challenge. In 2021, 99% of freight transport was powered by an internal combustion engine with Diesel as fuel and without any type of electrical assistance in the propulsion system. Moreover, polluting emission limits such as the Euro 6 are achieved with complex post-treatment systems that also add to the consumption of Urea.

<div class="section abstract"><div class="htmlview paragraph">State of the art battery electric vehicles (BEVs) become increasingly attractive, thanks to their top performance and high energy efficiency. Nevertheless, despite improvements in electric motors efficiency and motive batteries technology, there is still space for improving BEVs’ autonomy. Among others, use of a multi-speed, instead of a single-speed transmission system has the potential to optimize BEV’s energy consumption and driving range. In this respect, the scope of this work is to demonstrate a novel model-based approach for evaluating the potential of multi-speed gear box technology. For this purpose, advanced vehicle modeling was combined with statistical analysis tools and an optimization algorithm, with an aim to optimize gear ratios and the respective gear shifting strategy, ultimately maximizing BEV’s autonomy and performance. Respective results allow for an in-depth analysis of the multi-speed transmission system, already at early stages of a BEV development, which can eventually minimize battery electric powertrain system design time and cost.</div></div>
