PSA B22 7110 Standard Specifications - Engine Air Intake Line - Air Supercharger

The “ PSA B22 7110 Standard technical specifications - Engine air intake line - Air supercharger” standard , developed by PSA, a French multinational automotive company that produces cars and motorcycles under brands such as Peugeot, Citroen, and Opel, describes the requirements that the pressurized air intake line, which consists of air intake ducts and parts downstream of the turbocharger in turbocharged engines, must meet. The pressurized air intake line is located in the product development tree structure: vehicle - engine - interface adaptation - engine and body air line. The geometry of the interfaces, which are joined with tangential screw clamps and have elastic reserve, is described in the “PSA B12 2120 Spigots and interfaces for pressurized lines” standard.

This standard applies to all air intake lines supplying air to PSA Peugeot Citroen series vehicles. If the part consists of an assembly consisting of several sub-parts (e.g., outlet turbo pipe + sleeve + inlet intercooler pipe), these standard specifications apply to the assembled part and the sub-assemblies.

The engine air intake duct is a crucial part of a vehicle's air intake system. The engine air intake duct is the duct or pipe that directs air from the outside air into the engine's air intake system and ultimately delivers it to the combustion chamber. Its primary function is to:

• Draws in air: Draws in fresh, filtered air from outside.
• Directs air: It moves air past components such as the air filter, mass air flow sensor, and sometimes a turbocharger or supercharger.
• It delivers air to the engine: It delivers air to the intake manifold where it mixes with fuel for combustion.

The engine air intake line is considered important for the following reasons:

• Performance: Ensures the engine receives sufficient oxygen for efficient combustion.
• Fuel efficiency: The correct air-fuel mixture improves fuel consumption.
• Emission control: Helps maintain clean emissions.
• Engine protection: Prevents dirt and debris from entering the engine.
