This paper presents the emission analysis of a 1.6L turbocharged CamPro engine installed with an electric turbocompounding (ETC) unit. The computational model was accomplished by using a validated 1D engine simulation GT Power. Initially the 1D engine simulation was run with the baseline engine, a 1.6L turbocharged CamPro engine. Then, the ETC unit was located downstream of the main turbocharger. The exhaust energy was recovered by a bespoke high speed Low Pressure Turbine (LPT) which drove the electric generator using a common shaft. The electric energy produced by the high speed electric generator was recorded from the engine simulation that was run from 1000 RPM to 6500 RPM with the increment of 500 RPM. The brake-specific emission, bsGasi, was used to analyse the effect of the ETC on the NOx, CO2, CO and HC. This paper found that the application of the ETC reduced the bsGasi. The maximum reduction of the bsGasNOx and bsGasHC was found at a higher RPM: NOX = 28.8% at 6500 RPM and HC = 9.9 % at 4500 RPM respectively. Additionally, the highest reductions for the bsGasco2 and bsGasco were found at 3500 RPM where the CO2 = 6.9% and the CO=7.2%.
