[Abstract]

　The objective of the study is to clarify regeneration and conversion techniques for abandoned heat energy in exhaust gas from automotive diesel engines during road driving conditions for improving fuel consumption and consequent CO₂ reduction of vehicles. From an estimation based on a conventional turbocharger system equipped on a direct injection diesel engine with the displacement 8000cm³, an exhaust turbine generator system which is applicable to a turbo charged diesel engine was developed for trial.
　By the experimental result of the component test, 6kW was obtained as maximum generator out put with this system. Then this was combined with a heavy duty diesel engine and energy regeneration performances under various driving conditions were experimentally studied. As result, it is clarified that the energy regeneration with this method could be effective under high speed and heavy load operating regions of the engine.
