Land Rover Discovery 2 L359 Fuel Injector Nozzle Jet 2.2 CRDI 9687454480

The Land Rover Discovery 2 L359 2.2 CRDI Injector is an original component of the high-pressure fuel system, designed for 2.2 CRDI diesel engines in Land Rover vehicles. Precise fuel metering and proper diesel spray pattern are crucial for engine running smoothness, performance, and fuel consumption. This item from the Injector Nozzles group helps restore correct engine operating parameters after wear of the factory injector.

Purpose and Function in the Injection System

The presented injector is a component of the common rail system in the 2.2 CRDI engine, responsible for precisely delivering fuel to the combustion chamber under very high pressure. A properly functioning injector nozzle influences:

• stable engine operation across the entire RPM range,
• even mixture combustion and reduced smoke,
• maintenance of factory power and torque parameters,
• reduced fuel consumption and less strain on other injection system components.

By maintaining the original spray pattern characteristics, the injector helps preserve proper engine running smoothness, which is particularly important in heavier off-road vehicles and SUVs.

Benefits of Using an Original Injector Nozzle

Using an original injector in a Land Rover allows for the preservation of factory fuel dose control parameters, facilitating diagnostics and calibration in the workshop. The main advantages include:

• Compatibility with the Factory Engine Control Unit – no need for software modifications or installations.
• Proper fit for the cylinder head bore and high-pressure lines.
• Ability to use existing adaptation procedures and tests with standard diagnostic tools.
• Consistency with other common rail system components, reducing the risk of additional faults.

Choosing an original injector nozzle is particularly important for vehicles operated under variable load conditions, where stable injection parameters contribute to engine durability.

Product Characteristics and Condition

The offered injector belongs to the Injector Nozzles group and is a used part, allowing for an economical repair of the fuel system while maintaining original construction. The used condition means the part has been previously operated but can still be used as a replacement part after appropriate verification and potential adaptation in the vehicle.

Before installation, professional testing on a test bench and checks for leaks and spray pattern are recommended to match the injector to the current engine condition and other fuel system components.

Installation and Operational Tips

To fully utilize the potential of the offered injector, it is worth paying attention to several technical aspects:

• thorough cleaning of the cylinder head bore before installation,
• use of new sealing washers according to manufacturer's recommendations,
• checking the condition of high-pressure lines and for leaks after engine start-up,
• performing injector adaptation/coding if required by the engine control unit.

This approach minimizes the risk of leaks, uneven engine operation, and accelerated wear of other common rail system components.

Injection System Diagnostics and Prevention

If your Land Rover exhibits symptoms such as starting difficulties, rough idling, power loss, or increased smoke, it is worth familiarizing yourself with practical tips for identifying injection system problems.
