Injector Technical Characteristics

The presented injector belongs to the category of injector nozzles and is designed for Diesel engines. Its task is the precise atomization of fuel in the combustion chamber, which directly impacts performance, fuel consumption, and emission levels. The injector's design is adapted to the operating parameters of the OM651 unit, allowing for the maintenance of correct pressures and injection times specified by the manufacturer.

A properly selected injector in a diesel engine enables:

• stable idle operation without unwanted vibrations and RPM fluctuations,
• proper acceleration dynamics, without jerking or delayed response to the accelerator pedal,
• maintaining optimal mixture composition, which contributes to lower fuel consumption.

Application in Mercedes Vito W447 with OM651 Engine

The injector has been designed to work with the OM651 engine unit used in the Mercedes Vito W447 model. Thanks to this, the nozzle geometry, flow characteristics, and control method are matched to the injection maps of the factory engine control unit. The use of the correct injection element is crucial for:

• maintaining factory power and torque,
• reducing exhaust smoke under load,
• protecting the particulate filter through proper mixture combustion.

Selecting an injector compatible with the OM651 unit minimizes the risk of cold start problems, power drops, or errors being stored in the engine control unit.

Condition, Origin, and Benefits of Choosing a Used Injector

The offered component is used, which represents an attractive cost alternative to a new OEM part. For many fleet users and workshops specializing in commercial vehicle service, this is a reasonable compromise between price and maintaining the original manufacturer's design.

Choosing a used injector can be particularly beneficial when:

• a quick vehicle repair is necessary with a limited budget,
• the vehicle has high mileage and investing in a set of brand-new components would be disproportionately high,
• maintaining the original specification of the injection system without using aftermarket parts of uncertain origin is important.

If you want to better understand how to identify fuel system problems, it is worth reading the article describing diesel injector faults, their symptoms, and the consequences of neglect. This is a practical addition to your knowledge when planning repairs.

Importance of a Functional Injector in a Diesel Engine

In diesel engines like the OM651, a functional fuel injector is crucial for the durability of the entire powertrain. Incorrect diesel fuel metering can lead to:

• accelerated wear of pistons and cylinders due to improper combustion,
• increased load on the turbocharger from excessive exhaust smoke,
• problems with the exhaust gas treatment system, including the DPF filter.

Replacing a worn injector with a functional element from the same design family allows for the restoration of correct engine operating parameters, reduces the risk of costly secondary failures, and improves driving comfort.
