Rapid advances in science and technology require the invention of high-quality fuel that could ensure proper functioning of new mechanisms. Surprisingly enough, the use of biofuels in cars has been proposed since the beginning of automotive history [1]. At first biofuels that were widely applied by well-known inventors and industrialists seemed to be highly promising; however, low oil prices have driven it out from the market. Steady growth of the rolling stock of motor transport, especially automobile transport, has resulted in the increase of fuel consumption [2, 3]. Since oil reserves are exhaustible, transportation sector has generated an interest in replacing petroleum-based fuels with renewable or alternative fuels, biofuel being one of them. In fact, researchers have developed various methods of reducing fuel consumption and atmosphere contamination with emissions from automobile engines. The world automotive industry faces the problem of developing and producing new economical and environmentally friendly fuels [4, 5].

The importance of the problem of effective use of traditional energy sources and the search for alternative resources is beyond doubt. However, nowadays Ukraine does not fully use the potential of low-calorie gases, in particular, biogas, produced by agriculture and industry in large quantities. The number of available domestic installations for the disposal of this gas is negligible although a great number of developed countries have thousands of such facilities. One of the most advantageous sources of energy is biogas produced out of biological waste from communal and agricultural dumps - landfill sites for waste disposal. It is meanwhile burnt in flares or emitted into the atmosphere contaminating it heavily. The level of biogas used as a fuel in automotive internal combustion engines is very low. However, replacing gasoline with biogas results in engine power reduction and fuel consumption increase. This should be taken into account when operating cars in mountainous areas where atmospheric pressure and temperature are lower.
