This diploma thesis "The effect of CNG fuel combustion on the technical and economic parameters of the vehicle" deals with the use of alternative fuel of compressed natural gas for road vehicles. The thesis is divided into 4 main parts. In the first part there is a literary review, which deals with the history of the use of gaseous fuels in the world and in the Czech lands, as well as the characteristics and construction part of the car modified for CNG operation. The second part is an experimental measurement of performance parameters of two Škoda Octavia Combi III vehicles with a CNG, diesel and petrol engine at dynamometer testing laboratory, which is also described in this chapter. In the third part the results of experimental measurement are processed and commented and both vehicles are compared from the technical and economical point of view. As is evident from the measurement results, in a vehicle that is already equipped with CNG system from manufacturer combustion CNG does not have a negative effect on the engine's performance parameters and even more constant engine operation can be observed. Vehicles with CNG system are also more economical and ecological than vehicles combusting conventional fuels. The last part of this thesis is devoted to a discussion, where the measured results are compared with the results in an expert article dealing with the same topic.
