3360127 - 1072D MODULAR INLET MANIFOLD (V.I.S.)
DESCRIPTION OF COMPONENTS
MODULAR INTAKE MANIFOLD
Specifications
TypeAn intake manifold of modular length controlled by the injection control unit. Allows volumetric efficiency to be increased and thus:
- optimise torque delivery at low/medium speeds;
- increase power at high speeds.
Composition
StructureThe modular intake manifold consists of:
- two nylon halves
- a vacuum accumulator formed inside the manifold
- a modular intake device control actuator with built-in two-way control solenoid.
Operation
The injection control unit controls a two-way solenoid (1) that puts vacuum accumulator (2) into communication with pneumatic actuator (3), which allows swinging duct (4) to move via two linkages.When the swinging duct rotates, the ducts can take up the following configurations:long ducts, torque with speed up to 4700 rpm
MODULAR INTAKE MANIFOLD SOLENOID
Specifications
TypeA two-way solenoid built into the pneumatic actuator controlling the modular intake manifold. Controlled by the injection control unit.Its function is to allow the vacuum present in the vacuum tank (inside the intake chamber) to act on the pneumatic actuator controlling the swinging duct.
