In modern transport, environmental control plays a key role in shaping the strategy for managing the technical condition of nodes and systems. The first step in reducing the toxicity of exhaust gas emissions was the introduction of EURO standards, successively from EURO-0 to EURO-6. Accompanying the appearance of EURO standards, exhaust systems were supplemented with catalytic converters, which deactivated most of the harmful emissions. Oxygen sensors also began to play a key role, the installation of which resulted in the appearance of feedback. Thus, the global automotive industry is closer to the controllability of the engine output parameters. However, there are not enough parameters, operating modes, and additional controls available for this purpose. The presented studies used a new method of selective control of exhaust gases in each cylinder. The following parameters were used for monitoring: the crankshaft speed, complete and partial (cycle-by-cycle) disconnection of cylinders, O2, CO, CO2, and CH. The mode was provided by the number of the engine’s disconnected operated cycles and the crankshaft speed. The control was performed by the internal adjustment of the fuel supply under the influence on the injection duration of the electromagnetic nozzle. During the research, we established the minimum values of the exhaust toxicity parameters during the test effects. This method with a combination of modes and parameters allows us to reduce the toxicity of exhaust gases and to improve the efficiency and effectiveness of vehicles.
