Abstract. Currently, the generation of heat engines and their control systems are based on ecological indices such as the toxicity of the fulfilled gases. When designing motors, software packages are widely used. These software packages provide the ability to calculate the workflow of engine at steady-state conditions. The definition of indicators emissions is a difficult task. The distribution statistics of the modes shows that the engines of the transport units work on unsteady modes most of the time. The calculation of toxicity indicators is even less developed.
In this article experimental and numeric study of the diesel engine with turbocharger exhaust toxicity was considered.
As a result of the experimental study, which was conducted with single-cylinder diesel engine compartment simulated work on the transient state, working process characteristics of a diesel engine were obtained, including carbon and nitrogen oxides concentrations.
Functional dependencies of concentrations of toxic exhaust components, such as carbon and nitrogen oxides, on excess air ratio and exhaust temperature were obtained.
Diesel engine transient processes were simulated using developed mathematical dynamic model of combined engine in locomotive power plant with a change in control signal (position of locomotive driver’s controller) and external influence signal (resistance moment). The
analysis of exhaust gas toxicity was conducted.
Key words: diesel engine, toxicity of exhaust gases, concentration of toxic components, power plant diesel locomotive, mathematical model.
