The paper presents the results of an experimental study of the influence of a turbocharger turbine on the thermal and mechanical characteristics of gas flows in the exhaust system of a piston internal combustion engine (ICE). The experiments were carried out on a full-scale model of a single-cylinder engine under the conditions of gas-dynamic non-stationarity (pulsating flows). The article describes the laboratory setup and the methodology for conducting experiments. The analysis of the dependences of the instantaneous velocity and pressure of the pulsating flow, as well as the local heat transfer coefficient in time in the exhaust pipe of the piston engine with and without a turbocharger (TC), is presented. It is shown that the placement of the TC turbine in the gas-air path of the piston ICE significantly affects the gas-dynamic, flow and heat exchange characteristics of gas flows in the exhaust system. The installation of the turbocharger causes restructuring of the structure and flow regime in the exhaust system. |
