Návrh měření provozních parametrů turbodmychadla na stávajícím experimentálním standu vybaveném vznětovým spalovacím motorem

Abstract

Diploma thesis is devided into two parts - theoretical and practical. The theoretical part is focused on a general description of the internal combustion engine, a more detailed description of the diesel internal combustion engine and an approach to the issue of supercharging. The practical part proposes a suitable system for measuring the required quantities, location and design of measuring points, method and procedure for determining the efficiency of the turbocharger and modification of the current system to measure the operating parameters of any type of turbocharger. From the measured values, the characteristics of specific work, blower power and efficiency, specific work, turbine power and efficiency were developed. A schematic of the experimental stand and instructions for laboratory measurements and determination of the turbocharger operating parameters are documented in the appendix of the thesis.
