Purpose and Role in the Injection System

The fuel injector nozzle in a diesel engine is responsible for forming a precise fuel stream under high pressure. In the 2.2 HDI units used in the Citroen Relay / Boxer 35L, a properly functioning nozzle is crucial for:

• maintaining smooth engine operation across the entire RPM range, even under heavy load,
• stable cold starts and reduced exhaust smoke,
• optimal mixture combustion, which helps keep fuel consumption at a predictable level,
• reducing vibrations and noise typical of diesel engines.

In commercial vehicles like the Citroen Relay / Boxer 35L, an efficient injection system is particularly important due to frequent driving with full loads and in urban cycles.

Technical Characteristics and Compatibility

The presented nozzle belongs to the Injector Nozzles category and is a component of the Diesel engine fuel system. It has been designed to work with the 2.2 HDI unit, where high fuel dose repeatability and the correct injection spray pattern are required.

Key functional features include:

• suitability for Diesel fuel,
• compatibility with the original Citroën injection system in Relay / Boxer 35L 2.2 HDI models,
• maintaining the spray parameters required by the combustion chamber design of this engine unit.

By preserving the original spray geometry, the nozzle allows for the maintenance of factory engine performance characteristics, which is important for both the performance and durability of the engine unit.

Condition, Verification, and Service Application

The offered Citroën fuel injector nozzle is a used part intended as a replacement component for the repair or refurbishment of the injection system. Such elements are most often chosen in situations where symptoms such as:

• uneven engine operation at idle or under load,
• increased exhaust smoke during acceleration,
• loss of power and flexibility of the engine unit,
• noticeable jerking within a specific RPM range.

Selecting the correct nozzle for a specific 2.2 HDI engine is crucial for the effectiveness of the repair. It is advisable to verify the part's compatibility with the vehicle based on catalog data and manufacturer specifications.

Benefits of Using the Correct Injector Nozzle

A correctly selected and functional injector nozzle in the Citroen Relay / Boxer 35L 2.2 HDI allows for:

• maintaining predictable fuel consumption in daily fleet and individual operation,
• reducing the risk of secondary damage (e.g., excessive load on pistons, valves, or the particulate filter),
• stable engine operation with high mileage, typical for commercial vehicles,
• easier diagnosis of the injection system by maintaining the part's factory parameters.

Replacing a worn nozzle is one of the basic service actions for problems with the injection system in diesel engines, especially in vehicles used intensively in transport.
