Modern diesel building is developing in the direction of emissions with exhaust gases reduction and improvement of unit power, fuel efficiency, and engine lifetime. The achievement of high ecological, technical and economic indexes in diesel-fueled vehicles demands power efficient control and improvement of devices, which realized gas exchange processes. Exhaust gases energy is used in the gas exchange system of diesel-fueled vehicles. It is necessary for the improvement of diesel-fueled vehicles gas exchange efficiency to combine in one device the control of all of the following procedures: exhaust gases recirculation into the cylinder under small and no-load conditions for nitrogen oxide emission reduction; exhaust gases bypassing under turbocharger control on variable load operation for carbonic oxide, soot, and particulate matter emission reduction; exhaust gases use for air ejection in the process of circulation through charge air cooler under cooling conditions before air injection into the cylinder.
