Suction tubes, charge air cooler, suction tube module, motor system and method for dimensioning same

The output suction tube (108) comprises a volume portion which is changed in response to the displacement of motor (102), for determining the number of exhaust gas recirculation sprayers of the engine injection nozzles. The volume portion of the output suction tube is determined depending on the displacement of motor, depending on the number of exhaust gas recirculation sprayers of the engine injection nozzles, and the feedback parameters. Independent claims are included for the following: (1) a method for dimensioning output suction tube; (2) an input suction tube; (3) a method for dimensioning input suction tube; (4) an intercooler; and (5) a method for dimensioning intercooler.
