Heat Generation Inside Turbocharger Without External Heat Source

Recently, many vehicle manufacturers started to invest in new technology reduce the emission produced by their engines. Due regulations that become more stringent and rising demand for highly efficient vehicles, technologies were introduced achieve demand. One of gain popularity modern vehicles is applying force induction systems such as turbocharging supercharging engine. By using turbocharger, two major advantages can be achieved which are increasing engine efficiency size reduction. However, turbocharger performance will affected amount heat generated due friction inside bearing, air compression process also transfer from exhaust gas has high temperature pressure. In this paper, generation unit without any external source was measured analysed. A Garrett Turbocharger where model GT2056 used experiment. The operating speed study recorded between 20 000 rpm until 70 at turbine inlet compressor room temperature. parameters difference side, bearing housing side. From results obtained, it concluded produces a higher compared side while experience loss.
