The expediency of using vehicles of liquefied petroleum gas as a motor fuel, as com-pared with traditional liquid motor fuels, in particular with diesel fuel, is shown. The advantages of converting diesel engines into gas ICEs with forced ignition with respect to conversion into gas diesel engines are substantiated. The analysis of methods for reducing the compression ratio in diesel engines when converting them into gas ICEs with forced ignition has been carried out. It is shown that for converting diesel engines into gas ICEs with forced ignition, it is advisable to use the Otto thermo-dynamic cycle with a decrease in the geometric degree of compression. The choice is grounded and an open combustion chamber in the form of an inverted axisymmetric “truncated cone” is developed. The proposed shape of the combustion chamber of a gas internal combustion engine for operation in the LPG reduces the geometric compression ratio of D-120 and D-144 diesel engines with an unseparated spherical combustion chamber, which reduces the geometric compression ratio from ε = 16,5 to ε = 9,4. The developed form of the combustion chamber allows the new diesel pistons or diesel pistons which are in operation to be in operation to be refined, instead of making special new gas pistons and to reduce the geometric compression ratio of diesel engines only by increasing the combustion chamber volume in the piston. This method of reducing the geometric degree of compression using conventional lathes is the most technologically advanced and cheap, as well as the least time consuming.

The automotive sector is one of the fastest growing sectors of economy. The increasing amount of cars both in Polish and world roads results in the immeasurable benefits associated with the goods and human transport. On the other hand, this phenomenon caused the contamination of the environment. During the fuel combustion in petrol or diesel engines, the harmful gases, for example CO2, NOx and SOx are emitted. Apart from the negative impact on the environment, the emission of the aforementioned gases results in the deterioration of human conditions, as well as, the development of civilization diseases. In order to minimalize the harmful influence of an automotive industry on the environment, new technologies which can reduce the consumption of fuel or limit the fumes emission are developed. The first part of paper presents new solutions in an automotive sector which influence on the decline of the negative impact of automobiles on the environment. Additionally, proposed solutions affect the development of a car industry, taking into consideration environmental aspects.
