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 a 2-stage turbocharger, high torque at low engine speeds, high response, and high output at high engine speeds have been achieved as well as suppression of NOx and PM emissions.
