Common Rail Injector LI3

Product catalog summary
Overview: The LI3 Injector is designed for large diesel systems in sectors such as mining, railway, maritime, and power generation. It is engineered for high reliability and robustness, especially in harsh conditions involving aggressive fuels and high-impact vibrations up to 10 g.
Design and Features: The injector features a double-walled housing, flat-seat control valve, and coated components to enhance durability. It includes a hydraulic design that resists internal deposits and ensures continuous leak-free operation with minimal control leakage (< 50 ml/min). An integrated high-volume pressure tank eliminates the need for a rail, reducing pressure loss. The injector offers flexibility with various housing geometries and nozzle variants, manufactured in-house for customer-specific adaptations.
Technical Specifications:
  • System pressure: 300 – 2,200 bar
  • Nozzle diameter: 13 mm
  • Nozzle flow: 1,600 – 4,000 ml/30 sec
  • Number of injections: Up to 4
  • Minimum injection separation: 400 µs
  • Maximum power per engine cylinder: 250 kW
  • Permanent leakage: 0
  • Control leakage: < 50 ml/min at 2,200 bar
  • Injector configuration: Single- or T-connector
  • Weight: ~ 4.4 kg
  • Service life off-highway: 15,000 hours
  • Number of holes: 6 – 10 in one row
  • K-factor: 0 – 3
  • HE factor: 10 – 30%
  • Ambient conditions: -40 °C to +125 °C
  • Vibration specification: VDI 3838 / ISO 10816-6
Compliance and Standards: The injector meets standards such as VDI 3838, ISO 10816-6, IP6K9K, TA Luft, US EPA Tier 4f, and IMO III, ensuring its suitability for the harshest environments.
Applications: The LI3 Injector is applicable in mining, marine, and power generation industries.

Common Rail Injector LI3-1

Short Description Common Rail Injector LI3 The LI3 Injector has been specially developed for large diesel system applications in the mining, railway, maritime and power generation segments. Extremely high reliability and robustness when faced with aggressive fuels and harsh conditions of use with regard to vibrations at impact loads of up to 10 g are vital for such kinds of applications. For this reason, the injector design is equipped with a double-walled housing, flat-seat control valve and coated components. The hydraulic design provides functional resistance against internal deposits (IDID). For maximum efficiency, the LI3 features a continuous leak-free operation and is configured to ensure minimum control leakage < 50 ml  min. Due to an /  internal, high-volume pressure tank with up to 43 cm³ no rail is required and the pressure loss is minimised. Different types of housing geometries and nozzle variants are possible. Supreme flexibility for customer-specific adaptation is achieved through the in-house manufacturing of the nozzles, control valves and other function-relevant micro-precision parts. Features • Continuous leak-free operation • Minimum control leakage (< 50 ml / min under full load) • Stable multiple injections, up to four injections possible • Pressure tank integrated in injector – no rail required • High flexibility thanks to individual in-house manufactured nozzle variants • Individual housing geometries possible • Variants with radial and axial high-pressure connector • Robust and reliable in the harshest environments according to VDI 3838, ISO 10816-6, IP6K9K • Double-walled injector housing for maximum security • TA
