Exhaust gas recirculation device for motor vehicle, has recirculation conduit with injector injecting water spray, from reservoir recovering water from gas and by condensation, in conduit and injectors injecting water in combustion chambers

摘要

The device has an exhaust gas recirculation conduit (28) connected with a recirculation valve (28a), and having a heat exchanger (30) cooling an exhaust gas. The conduit has an injector (31) to inject water spray, from a storage reservoir (14) recovering water contained in the gas and obtained by condensation in a condenser of an engine, in the conduit. Injectors (25) inject water from the reservoir into combustion chambers (3). An independent claim is also included for a method of partial recirculation of exhaust gas in a combustion chamber of an internal combustion engine of a motor vehicle.
