The paper is focused on fuels, their users - engines and the end-user, the vehicles, from an environmental and economic point of view. The basic characteristics of potential fuels for internal combustion engines, as well as possible sources of electricity, are analysed. A comparative analysis of characteristics of vehicle propulsion with gasoline, diesel fuel, compressed natural gas, liquefied petroleum gas and electricity was performed. The research has shown that the application of vehicles with an electric motor is ecologically justified only in cases of obtaining electricity in an environmentally friendly way and that in other cases there is no profit in an ecological sense. From an economic point of view, if there were no subsidies to manufacturers and buyers of electric cars, they would not be competitive with internal combustion engines now. Within the research, potential solutions for reducing air pollution and improving the quality of life in cities have been proposed.

“…A different fueling strategy using these types of fuels is called direct dual-fuel stratification (DDFS)-the difference is the use of direct injection for both fuels used in the engine [37]. Direct injection of two fuels requires the use of several injectors or a special injector, such as the product offered by Westport corporation [38], which has been mentioned in all relevant publications covering dual-fuel engine solutions [39]. A schematic of DDFS is shown in Figure 7.…”

This article discusses the problems of exhaust gas emissions in the context of the possibility of their reduction through the use of fuels with hydrogen as an additive or hydrotreatment. These fuels, thanks to their properties, may be a suitable response to more and more demanding restrictions on exhaust emissions. The use of such fuels in reactivity controlled dual fuel engines (RCCI) is currently the most effective way of using them in internal combustion (IC) engines. Low-temperature combustion in this type of engine allows the use of all modern fuels intended for combustion engines with high thermal efficiency. Thermal efficiency higher than in classic engines allows for additional reduction of CO2 emissions. In this work, the research on this subject was compiled, and conclusions were drawn as to further possibilities of popularizing the use of these fuels in a wide spectrum of applications and the prospect of using them on a mass scale.

Nowadays, internal combustion engines are being developed in the directions that allow to maximize the efficiency of their work, in order to make the most economical use of fuels. The low-temperature method of burning fuels in HCCI engines - Homogenous Charge Compression Ignition - allows to improve the efficiency of the engine, thanks to the reduction of energy lost during cobustion process. For the further development of engines with this type of mixture auto-ignition, with increasing the range of fuels used for that king of engines, it is necessary to develop the RCCI engines. Reactivity-Controlled Compression Ignition - RCCI - is the way to control the air-fuel mixture auto-ignition by using the injection of second fuel injected into the combustion chamber before the combustion begins. The development of modern compression ignition engines is strongly dependent on engines with this type of ignition. Using two fuels with different physicochemical properties makes it possible to control the time of compression ignition and allows to use engine in full range of operation. RCCI is a special type of HCCI engine that allows to use many types of fuels with high combustion efficiency and low emission of harmful exhaust components. The paper analyzes the issues related to the adoption and development of engines with this method of ignition.
