Abstract. The internal combustion engine is a highly intellectual product of civilization. Having reached the highest level of its perfection it, however, caused considerable ecological problems. Thus, its alternative has been the subject of active researches. The aim of this article is to define the objectivity and plausibility of these claims concerning the internal combustion engines and the perspectives of its employment in the gear of mobile machinery. The attention is focused both on the characteristics of the engine itself and on the characteristics of exploited energy sources. Ecological problems are usually related to the existence of carbon in the traditional fuel. But simultaneous operating of the notions of mass and capacity or higher and lower heat of fuel combustion as well as the notions of heat producing capacity of the fuel proved that there is no unconditional alternative to the common petrol. It is strongly believed that the substantial effectiveness can be expected from advancing the technology of volumetric ignition by compression of ideal homogenized working mixture, the technology known as Homogeneous Charge Compression Ignition. This technology enables the extreme increase in effectiveness of the internal combustion process distinctive of the Otto-engine. Thus, the objectives of Otto-engine improvement are considered to be absolutely achievable, which opens vast perspectives of its exploitation in the gear of machinery with the high level of autonomy.
