INTERNAL COMBUSTION ENGINE WITH TURBOCHARGER

摘要

An internal combustion engine mounted on a vehicle has a turbocharger. When there is an acceleration request, response of the turbocharger is appropriately enhanced by effectively utilizing gas stored in a container. In the internal combustion engine (10) with the turbocharger (58), the pressure in the pressure storage container (78) can be supplied to a turbine wheel (48) when the vehicle is accelerated, and pressure supply from the pressure storage container (78) is suppressed until a predetermined time elapses after acceleration is requested. When the turbocharger (58) is a variable nozzle turbocharger, the timing of opening a control valve (80) provided between the pressure storage container (78) and the turbine wheel (48) is delayed so that pressure supply from the pressure storage container (78) is suppressed until the angle of a vane (62) is controlled to a predetermined angle on the closing side after acceleration is requested.
