Internal combustion engine oxidant gas feed procedure uses fresh air and recycled exhaust gas mixed in proportions to achieve required temperature

摘要

The oxidant gas feed procedure, in which a mixture of fresh air and recycled exhaust gas is delivered to the engine's inlet manifold (A) from a fresh air intake and a recycled exhaust gas inlet (11) through a pipe (21) via cooler (R) or a bypass loop (22), has the proportions of the gases in the mixture controlled to give the required temperature for the gases entering the engine (M) according to its operating mode. For example, the degree of cooling is increased when the engine is under load, and reduced when the load is low.
