Ducati IWP 048 Injector Flow Rate and Spray Type

The IWP048 injector is used on some Ducati motorcycles and various cars such as Peugeot Fiat and is an essential component for the correct functioning of internal combustion engines, especially those of Ducati motorcycles. This type of injector is known for its efficiency and precision, which contribute significantly to performance. Let's take a closer look at the technical characteristics, flow rate, spray pattern and the impact of these factors on engine performance.

Technical Features of the IWP 048 Marelli Injector

The IWP069 injector is designed to ensure precise fuel dosing in the engine. Among the main technical features that they must have are:

• Operating pressure : IWP 048 injectors operate at a typical operating pressure of 3 bar, which is adequate to ensure efficient fuel injection.
• Structure : The multipoint injection configuration allows for homogeneous fuel distribution, improving combustion and reducing emissions.
• Connector: EV1
• Collar: Red
• Injector type: Pico
• Injector length: 47mm

Injector Flow Rate

The flow rate of an injector refers to the amount of fuel it can spray per unit of time. The IWP 069 injector is calibrated for an optimized flow rate for the injector datasheet specification of exactly 220cc/min. On our test bench, exactly cleaned as new injectors measure 234cc / minute at 3bar.

Spray Type

The spray pattern of an injector is crucial to the efficiency of fuel combustion. The IWP 048 uses a spray pattern that promotes fuel atomization through 5 holes.

Impact on Engine Performance

Thanks to its precision and reliability, the IWP 048 injector has a positive effect on the overall performance of the engine and a well-calibrated fuel injection optimizes the power output. This is especially important for pilots who want both exceptional performance and stable, smooth idling and fair consumption.

Maintenance and Care

To keep IWP 048 injectors at peak performance, regular maintenance is essential. This includes cleaning the injectors regularly to prevent carbon deposits and using high-quality fuels to minimize the build-up of impurities. Periodically, it is advisable to perform checks to ensure that the flow rate and spray remain within the parameters specified by the manufacturer and overhaul them with specific cleaning fluids and equipment such as ours that are difficult to find, even with ultrasonic technology.

As you can see below in the photo, it is easy to find that the same injectors get dirty or damaged during their life, and so below you can observe the difference in spray, on the left an uneven spray while on the right, a fine jet spray with a consequent reduction in flow rate and consequently in the performance and reliability of the engine itself.

Along with cleaning, it is essential to replace the filters that these Marelli type injectors have, inserted in the upper part of the injector.

You must also always be careful when handling them as a simple accidental fall of the injector on the ground could necessarily lead to its replacement.

In conclusion, the Marelli IWP 048 injector used as standard on the Ducati motorcycle but can also be used on many engines of cars subject to preparation and is a key element that determines the efficiency and performance capacity of the engines to which it is associated. Understanding its function and its maintenance can help extend the life of the engine and optimize its performance.
