Summary:External or integrated water-cooled exhaust manifolds are mentioned to be favourable for the overall engine behaviour on diesel and gasoline engines. To validate this potential, an analytical study has been conducted. A diesel and a gasoline engine model were built-up in GT-SUITE to assess the influence of water-cooled exhaust manifolds at full load. These engine models have been combined with VeLoDyn - a tool from IAV for vehicle simulation considering heat fluxes between engine and vehicle cooling system - to show the potential of the different designs in a driving cycle, including the catalyst heating up phase.
