Temperature Distribution Analysis of an Insulated Turbocharger Manifold

Abstract

In the past years, many research efforts have been made on the temperature distribution of the turbocharger. In this study, the effect of thermal heat management on manifold surfaces at turbocharged engine performance is experimentally investigated. In this test, the insulation of the manifold on the turbocharger is aimed at reducing the heat losses and thus increasing the indicated efficiency. Thermal heat management was used to simulate the engines. The insulation of the exhaust manifold with the coating, which is silicone resin based, and the thermal wrap influences the heat transfer process and hence the performance and exhaust emissions characteristics of the engines. The purpose of this paper is to analyse the temperature distribution of the turbocharger’s manifold and consider the engine performance by using a thermal imaging camera and dynamometer. The experimental research was conducted on one-cylinder, two-stroke with Lifan engine 160 cc equipped with the turbocharger. The turbocharger used is the non-standard Turbo RHB31 VZ21 for this engine as it is usually used for car engine applications.
