The results of experimental studies of the motor vehicle 6HCHN 13/14 (6 cylinder, gas, four-stroke, supercharged engine, with a cylinder diameter of 130 mm and a piston stroke of 140 mm) are presented with the supercharging and electronic distributed gas supply. The purpose of the study is to verify the adequacy of the declared characteristics of the control system with the distribution of gas directly to the control facility; estimation of the influence of the parameters of the operation of the control system with the distribution gas supply on the indicator indicators of the engine. Approval of the control system with distributed gas supply was carried out at the test bench to study the workflow of the 6GCHN 13/14 inflatable gas engine, which is equipped with a spark ignition system of high energy and gas turbine supercharging. The stand is equipped with a measuring complex. The efficiency of the distribution system for the distribution of gas in relation to the classical power system was evaluated by comparing the indicator indicators of the work process. In the operation of the engine with the distribution of gas, the increase in the indicator power was 17%, the average indicator pressure was 2.9%, and the indicator fuel consumption decreased by 6.75% at the crankshaft speed of n = 1054 min^-1 and the excess air ratio α = 1.8. Approbation of the control system with distribution gas supply has shown its ability to work in the gas engine 6HCHN 13/14 and adequate implementation of the functions assigned to the system. At the same time, the application of a distributed gas distribution system contributes to increasing the performance of the working process while ensuring the concept of "poor combustion".
