Purpose and Role in the Fuel System

The injector nozzle in an N43 gasoline engine is responsible for the precise atomization of fuel in the combustion chamber, which directly impacts the smoothness of operation, performance, and fuel consumption. In BMW units employing advanced mixture control, a correctly selected injector is crucial for:

• maintaining stable idle speed and reducing engine vibrations,
• proper throttle response across the full load range,
• maintaining compliance with emission standards and the correct operation of lambda sensors and the catalytic converter.

Benefits of Using an Original BMW Injector Nozzle

Using a factory injector nozzle in an N43 engine allows for the preservation of manufacturer-specified parameters. In practice, this means:

• precise gasoline metering according to the engine control unit's maps,
• compatibility with factory ECU software without the need for software modifications,
• proper cooperation with other fuel injection system components, such as the fuel rail, pressure sensors, or high-pressure pump.

For the user, this translates into predictable vehicle behavior, easier diagnostics, and a reduced risk of fuel-air mixture related errors.

Technical Characteristics and Compatibility

The offered nozzle belongs to the category of injector nozzles and is designed for gasoline engine fuel systems. The component's design is adapted to the specifics of BMW N43 units, which require very precise fuel metering control under varying operating conditions.

Thanks to the use of an original BMW solution, the following are maintained:

• appropriate fuel flow characteristics across the entire working pressure range,
• correct spray pattern ensuring uniform filling of the combustion chamber,
• compatibility with factory electrical connectors and mechanical mounting in the cylinder head.

Component Condition and Service Application

The injector nozzle is offered as a used part, which is a sensible service solution for repairing or replacing a single injector in an N43 engine. These types of components are often chosen for:

• resolving issues with uneven engine idle,
• diagnosing misfires on a specific cylinder,
• fuel system repairs after identifying improper fuel atomization.

Replacing the injector nozzle with an original BMW part allows for the restoration of correct engine operating parameters without altering the engine's construction.
