Designed to ensure a’precise delivery of high-pressure fuel, this injector è is compatible with Euro 4 and Euro 5 engines, and è is used in light applications, mainly city cars and compact cars.

Technical specifications

The’injector 9663429280 è is a Siemens/VDO model. Its main features include:

• Common Rail technology with multiple management of’injection (pre-injection, main, post-injection);
• Operating pressure up to 1.600 bar, with direct electronic control by the engine control unit (ECU);
• High precision nozzle with calibrated diesel atomization;
• Specific coding of the’injector (IQA value) for recognition by the ECU;
• Connector with 2 pins for electrical connection;

DIPA canò intervene to revise these spare parts thanks to its experience and expertise.

Functionalityà

The task of the’injector è is to precisely dose the amountà of fuel to be injected into the combustion chamber, based on the parameters processed by the engine control unit. The correct functionalityà of the’injector è is essential for:

• ensuring a quick and smooth start;
• reducing consumption and pollutant emissions;
• avoiding vibrations and noise.à anomalies;
• ensure the engine's response during acceleration.

In case of malfunction, the’injector canò alter the’balance between the cylinders and compromise combustion, causing loss of power or complete failure.
