Injection test bench

Key data:

• Common rail diesel injection
• Digital image capture (individual high-resolution images and high-speed recording)
• Optically accessible chambers
• Various types of injector can be used (magnetic/piezo injector)
• Variation of ambient medium (injection into air/oil)
• Fully variable injection parameters (pressure, duration, control cycle, etc.)

Measurement data:

• Control parameters of injector
• Camera parameters
• Rail pressure
• Spray pattern
• Temperature (injector, chamber, surroundings, etc.)
• Time stamp of recording (trigger settings)

Aspects and analysis:

• Free configuration of the injector’s control parameters
• Infinite variation of rail pressure
• Testing the reproducibility of injection
• Analysis of various environmental conditions
• Analysis of various homogenization strategies
