Temperature regulation for engine intake air and recirculated exhaust gas, uses single unit housing two heat exchangers to exchange heat between exhaust gas, fluid and intake air, with control of fluid flow

摘要

The regulation has a first device (30A) for heat exchange between a fluid and the intake air, and a second device (30B) exchanging heat between the fluid and recirculated exhaust gas. These two devices are integrated into a principal heat exchanger (30). A fluid circulation path (32) common to both parts (30A,30B) of the principal heat exchanger is regulated (54) to control temperature.
