For many decades to come, and in the foreseeable future, internal combustion engines – in many cases with electric motors – will be with us, just like the liquid fuels they require. The importance of crude oil will decline, as these fuels will be increasingly produced on a synthetic basis without CO2 emissions. The answers to the question ”Future Mobility without Internal Combustion Engines and Fuels?“ are “no” in both cases. Purely battery-electric mobility will be applied in the future only in specific areas. Fuel-cell vehicles will hardly be used because of the extreme infrastructure investment costs. In contrast, liquid fuels will ensure the future of mobility. In this scenario, energy such as solar or wind energy will be generated without CO2 emissions.

Natural Wind

The response of vehicles to the transient forces associated with gusting of the natural wind is assuming greater prominence. Total reliance upon natural gusts is unsatisfactory since these are unpredictable and unrepeatable. Major Continental manufacturers have for several years utilized gusts produced by multiple-fan installations, the power source being either electric motors or internal-combustion engines. The M.I.R.A. equipment is centred on a single Rolls-Royce Avon gas-turbine engine, the exhaust gases from which are directed across a roadway. Measurements have indicated that the gust profiles are similar to those encountered on motorways in respect of rise-time.

Ic Engines

The recent transport electrification trend is pushing governments to limit the future use of Internal Combustion Engines (ICEs). However, the rationale for this strong limitation is frequently not sufficiently addressed or justified. The problem does not seem to lie within the engines nor with the combustion by themselves but seemingly, rather with the rise in greenhouse gases (GHG), namely CO2, rejected to the atmosphere. However, it is frequent that the distinction between fossil CO2 and renewable CO2 production is not made, or even between CO2 emissions and pollutant emissions. The present revision paper discusses and introduces different alternative fuels that can be burned in IC Engines and would eliminate, or substantially reduce the emission of fossil CO2 into the atmosphere. These may be non-carbon fuels such as hydrogen or ammonia, or biofuels such as alcohols, ethers or esters, including synthetic fuels. There are also other types of fuels that may be used, such as those based on turpentine or even glycerin which could maintain ICEs as a valuable option for transportation.

To Come

Today, the problem of energy shortage and climate change has urgently motivated the development of research engaged in improving the fuel efficiency of internal combustion engines (ICEs). Although many constructive alternatives—including battery electric vehicles (BEVs) and low-carbon fuels such as biofuels or hydrogen—are being put forward, they are starting from a very low base, and still face significant barriers. Nevertheless, 85–90% of transport energy is still expected to come from combustion engines powered by conventional liquid fuels even by 2040. Therefore, intensive passion for the improvement of engine thermal efficiency and decreasing energy loss has driven the development of reliable approaches and modelling to fully understand the underlying mechanisms. In this paper, literature surveys are presented that investigate the relative advantages of technologies mainly focused on minimizing energy loss in engine assemblies, including pistons and rings, bearings and valves, water and oil pumps, and cooling systems. Implementations of energy loss reduction concepts in advanced engines are also evaluated against expectations of meeting greenhouse gas (GHG) emissions compliance in the years to come.
