A new concept of a super charger for diesel engines is proposed and its performance is examined by TVD numerical simulation. The structure of the super charger has a simple duct-valve system which allows the feeding of compressed inlet air to the engine cylinder by an exhaust-gas driven chock wave. The two-dimensional unsteady flow of this duct-valve system was simulated by TVD numerical scheme applied to the Euler equations. It was found that the present supercharger has a performance which is preferable to low engine speed. The complicated wave interactions are simulated in detail.
