Subject-matter. Research in the field of monitoring the environmental parameters of the car when simulating various modes of loading the engine.

Purpose. The study of the development of resource parameters of catalysts and oxygen sensors exhaust system.

Methodology. Carrying out a full-scale experiment using the developed instrument, the “engine-loader” of the engine, which allows for the complete and partial disconnection of the cylinders for their loading and studying the changes in the toxicity norms.

Results. The conducted research set showed high efficiency in monitoring the technical condition of the cylinder-piston group, the fuel injection system, the ignition system and other systems due to monitoring of toxic emissions parameters.

Findings. A decrease in toxicity is observed in all experimental modes, however, the lowest levels of carbon oxides (CO) and hydrocarbon (CH) are observed in the mode with one operating cylinder at a crankshaft rotation speed of 3500 min-1. The greatest fuel savings are achieved at engine speeds of 3000 min-1.

Keywords: engine, diagnostics, rotational speed, toxicity, fuel efficiency, exhaust (exhaust) gases.
