Turbocharger Intake System - Volvo B5254T3 Manual

TURBOCHARGER INTAKE SYSTEM

Intake Manifold Lower Section
The intake system is divided into upper and lower sections.
The injectors are located on the lower manifold to mix the fuel with the turbulent air as efficiently as
possible.
The position of the injectors is optimized to minimize fuel film formation and improve emissions.
The lower intake manifold is aluminum to protect the fuel injection nozzles in the event of an accident.
There are individual ducts to each intake port to distribute the crankcase gases evenly between the
cylinders.
