“…The references [87][88][89] address fundamental aspects regarding the future of internal combustion engines, with similar evaluations to the present review. More specifically, Marin et al [87] highlight the evident offensive of the media to the ICE, especially after the Diesel-Gate, advocating the short-to the medium-term predominance of electric motors on the global fleet.…”

“…As transport contributes with only 10% of the world's total CO 2 emissions to the atmosphere, the use of the so-called CO 2 self-capturing cars has great potential to remove the above-mentioned 10% carbon dioxide, but also to reduce the other 90% emitted by industry, farming [88]. Strong and well-founded arguments are put forward by [88,89] regarding unilateral policies aimed at promoting electric vehicles over combustion ones. Consumers should have a free choice based only on technological competition between each solution, not on biased information about the future of mobility.…”

The sustainable future of mobility should not be viewed as the burial of the internal combustion engine (ICE), nowadays the main source of vehicular propulsion. Even with the increasing electrification of the transport means, the low global percentage of the electric fleet, around 0.2% of the total road vehicles, associated with an annual growth rate of less than 60%, indicates that they will not significantly change the market share in the short-and medium-term periods. This means that fuel demanded by ICEs and pollutant emissions generated by them will be very relevant in the years to come. Thus, the search for significant advances in technology associated with the use of renewable fuels is very important for environmental and economic sustainability. In this regard, the present work intends to demonstrate that the association between Brazilian ethanol and advanced technology in ICEs is a promising alternative for a more sustainable global mobility in the future. For this purpose, some ethanol properties are presented to justify its relevance as an ideal biofuel for highly boosted and efficient engines. Then, environmental, social, ethical and economic impacts arising from electric vehicles are investigated, demystifying the zero-emission vehicle terminology attributed to them and, finally, new technologies for ICEs are presented, proving that they are constantly evolving and improving, which is fundamental to the future of the world automotive fleet.

“…For the simulation of the liner deformation, the complex three-dimensional thermal effects, as well as the local stresses and strains, have to be regarded. This can be done with Finite Element Methods (FEM) [21]. The main challenge for FEM is the computational requirement and capacity, namely computational power, memory, and computational time.…”

Enhancing the Geometrical Performance Using Initially Conical Cylinder Liner in Internal Combustion Engines—A Numerical Study

Reducing friction is an important aspect to increase the efficiency of internal combustion engines (ICE). The majority of frictional losses in engines are related to both the piston skirt and piston ring–cylinder liner (PRCL) arrangement. We studied the enhancement of the conformation of the PRCL arrangement based on the assumption that a suitable conical liner in its cold state may deform into a liner with nearly straight parallel walls in the fired state due to the impact of mechanical and thermal stresses. Combining the initially conical shape with a noncircular cross section will bring the liner even closer to the perfect cylindrical shape in the fired state. Hence, a significant friction reduction can be expected. For the investigation, the numerical method was first developed to simulate the liner deformation with advanced finite element methods. This was validated with given experimental data of the deformation for a gasoline engine in its fired state. In the next step, initially conically and/or elliptically shaped liners were investigated for their deformation between the cold and fired state. It was found that, for liners being both conical and elliptical in their cold state, a significant increase of straightness, parallelism, and roundness was reached in the fired state. The combined elliptical-conical liner led to a reduced straightness error by more than 50% compared to the cylindrical liner. The parallelism error was reduced by 60% to 70% and the roundness error was reduced between 70% and 80% at different liner positions. These numerical results show interesting potential for the friction reduction in the piston-liner arrangement within internal combustion engines.

“…Reducing the consumption of hydrocarbon fuels within the transportation sector remains one of the most important challenges to reduce greenhouse gas emissions. Even if the development of electric vehicles is regarded as one of the preferred routes in coming years, most of the future projections agree that hybrid powertrains will continue to have a large market share in the next decades as underlined recently by Reitz et al [1]. Therefore, improvements in internal combustion engine efficiency are essential, in addition to the fact that internal combustion engine remains an effective and low risk technology pathway for energy transition.…”
