Characteristic of turbocharger-intercooler-ejector system, an at diesel engine

Methods of calculating the characteristics of the system, consisting of a turbocharger, intercooler and ejector, which installed after the turbine. It allows to determine the parameters of the charge air before the valves at any operating mode of the diesel engine, as well as to find to find an ability to control of the ejector. Calculation allow one to relate the parameters listed devices and determine the parameters of the charge air, as well as other parameters, such as the power of the turbocharger and the pressure and temperature of the gases in the main sections of the compressor and turbine in any diesel engine operation. The initial data for this calculation are geometric dimensions of the turbine, compressor, ejector, intercooler, known in the design calculation and current values of the pressure and exhaust gas temperature. Shows the characteristics of such a system designed for diesel 4T series. On the full-load curve showing changes in temperature and exhaust gas pressure before the turbine and in front of the ejector, the pressure and temperature of the charge air downstream of the compressor and after cooling, the pressure and temperature of cooling air to the ejector, and changing the degree of pressure rise in the compressor, the degree of the exhaust gas pressure reduction in the turbine of the turbocharger power, cooling air flow through the cooler, the degree of cooling of the charge air.
