INTAKE-AIR SYSTEM [SKYACTIV-D 2.2]

id0113z7003300


Purpose, Outline

•  A vacuum pump has been adopted which supplies stable vacuum to the power brake unit.
•  With the adoption of the two-stage air charging system, efficient, high air-charging is obtained in all driving ranges. As a result, low emissions, low fuel consumption, high torque, and high response are realized.
