ENGINE INTAKE SYSTEM
OVERVIEW AND OPERATION PROCESS
1. INTAKE SYSTEM LAYOUT
The intake system for the D27DTP (POWER UP) engine is equipped with the throttle body that
has a flap to block the air coming to the engine when the engine is switched off. Therefore, the
structure of the intake manifold has been changed.
Also, the improved HFM sensor (from HFM5.0 to HFM6.0) has been installed to control the
intake air precisely so that the NOx in the exhaust gas can be decreased.
