Product catalog summary

Introduction
The document introduces the LI1 injector platform designed for heavy-duty on-highway engines, emphasizing its flexible design and versatile application across various engine types.

Specifications
The LI1 injectors are compact, with a maximum length of 90 mm and a housing diameter of 21 mm. They operate at system pressures between 250 and 2,500 bar, with a nozzle diameter of 7 mm and a hydraulic flow rate of 400 to 1,200 ml/30 sec. The injectors are designed for a service life of up to 1.6 million km for heavy-duty on-highway applications.

Design and Functionality
The injectors feature a slim design for easy adaptation to various engine configurations. The Injection Timing Control (ITC) function is software-controlled, eliminating the need for additional sensors or electrical connections, thus simplifying engine tuning and application.

Performance and Efficiency
The LI1 injectors maintain consistent performance throughout their service life by precisely dosing fuel quantities. The platform is resistant to demanding fuels and offers high mechanical protection, meeting IP6K9K standards for vibration resistance.

High-Pressure Pump LP7.2
The LP7.2 pump enhances hydraulic efficiency with digital inlet valves and a design that minimizes dead volumes, contributing to reduced energy losses and fuel consumption. It is compact and easy to integrate into existing engine compartments.

Manufacturing and Quality
Liebherr's competence in microprecision manufacturing ensures high-quality, stable mass-produced components with minimal tolerance differences. The use of advanced materials provides strength and durability.

Applications
The LI1 injectors are suitable for engines ranging from 1 to 2.7 liters per cylinder, covering a wide range of light, medium, and heavy-duty applications.
