Purpose and Role in the Injection System

The Vent Hose Tube works with components in the injector nozzles category, responsible for controlled vapor discharge and pressure equalization within the fuel system. In BMW E87 116i and 118i models, proper venting is crucial for:

• stable fuel dosage supplied by the injectors,
• limiting pressure fluctuations in the supply lines,
• maintaining smooth engine operation across the entire RPM range.

Thanks to its correct geometry and fit within the BMW injection system, the vent tube helps reduce the risk of fuel supply disruptions, which is particularly important during dynamic driving and frequent load changes.

Compatibility with BMW E87 116i / 118i

The offered component has been designed with the fuel system architecture of the BMW 1 Series E87, specifically the 116i and 118i versions, in mind. This means:

• factory-fit for mounting points and hose routing in the engine bay,
• compatibility with the operating parameters of injectors used in these engine units,
• easier installation without the need for system modifications.

Selecting a vent hose that matches the BMW E87's design minimizes the risk of leaks, improper hose routing, and unintended stresses that could affect the durability of the entire system.

Characteristics of a Used Part

This product is categorized as used BMW parts, allowing for economical repair or replenishment of the injection system without compromising original geometry and purpose. For vent hoses, it is important that:

• the channel remains clear along the entire length of the tube,
• the connection ends allow for a sealed connection with other system components,
• the shape and length of the hose match the factory routing in the engine bay.

A properly selected, used vent hose allows for the restoration of correct injection system operating conditions without the need for costly modifications.

Significance for Injector Nozzle Operation

In BMW E87 116i and 118i vehicles, proper fuel system venting directly impacts the behavior of the injector nozzles. A functional vent hose contributes to:

• maintaining stable fuel pressure within the fuel rail and lines,
• reducing the formation of gas bubbles that can disrupt atomization,
• more predictable engine response to changes in load and throttle position.

For users who want to better understand the relationships between the condition of injection system components and engine symptoms, an article describing diesel injector faults – symptoms, consequences, and diagnostics may be helpful. Although it concerns diesel engines, many principles regarding diagnostics and the impact of the injection system on engine operation remain similar.
