“…Therefore, it requires electrification development of the powertrain with an advanced combustion strategies and advanced engine architectures. This new competitive technologies, such as micro hybrids, full hybrids, electric vehicles and fuel cells are running under development in line with the traditional technology such as the BMW i3 range extender 30 , the Honda Accord Plug-In 31 chassis model validations obtained at Argonne's Advanced Powertrain Research Facility 32 and other of many ongoing range extender application developments to reduce the overall powertrain costs with a low cost automotive engine for electric vehicles 33 . The engine weight is to be taken into account when discussing the hybrid vehicle in order to allow the increasing of the battery size and controlling the total vehicle weight.…”

Comparatively, this review is meant to focus on possible developments studies of the rotary engine design. The controversial engine produces a direct rotational motion. Felix Wankel derived the triangular rotor shape from complex geometry of the Reuleaux triangle. The Wankel engine simulation and prediction of its performance is still limited. The current work reviews rotary engine's flow field inside the combustion chamber with different commercial software used. It studies different parameters effect on the performance of the engine, such as the effect of the recess sizes and the shape-factor. It is found that the engine chambers design is one of the aspects of improvement opportunities.

The combination of two drive sources: the internal combustion engine and the electric motor in the hybrid drive system requires an appropriate control system to manage their operation. It relies on many variables, and the greater the degree of drive hybridization the greater is the degree of interdependence of the parameters involved. The article presents solutions of electric drive control algorithms with an additional power source in the form of an internal combustion engine (Range Extender). The results of simulation analyzes in the AVL Cruise program are presented, taking into account three control algorithms and two driving cycles. The obtained results indicate the necessity to take various input quantities into account in order to optimize the use of the combustion engine

Data of plug‐in hybrid electric vehicles (PHEV), that includes both traditional hybrids electric vehicles (HEV) with the additional opportunity to recharge the battery by plugging into an electric outlet such as the Toyota Prius Prime, and battery electric vehicles (BEV) with range extender such as the BMW i3 REx, demonstrate the need of a less constrained research and development to optimize the design of electric vehicles with range extender for better energy economy and range. BEV with smaller, rather than larger, batteries, and onboard high‐efficiency electricity production, are superior economically and environmentally, until the times the electricity production will be overwhelming renewable, there will be a widespread recharging infrastructure, materials to produce the batteries will be abundant and ethically sourced, and the disposal of the batteries will be properly addressed. A hypothetical BMW i3 with a 30 Ah battery pack, and a high‐efficiency ICE, may have an MPGe (miles‐per‐gallon equivalent) working electric of 127 miles, a MPGe between 62 and 127 while sharing the energy supply, and a MPGe of 62 only using the gasoline energy supply.
