Common Rail injector LI1

Thanks to its slim and compact design, the leakproof LI1 common-rail injector offers maximum flexibility in the motor space. The LI1 injector platform was specially designed for use in light, medium and heavy duty engines. The special injector design ensures that the mechanical nozzle holders can be easily exchanged and the latest emission standards can be met. The software-controlled Injection Timing Control (ITC) function can individually dose even the smallest amounts of fuel for each injector, thus ensuring a constant injection quantity per injector over the entire service life.

Maximal installation space within the engine

The particularly compact design of the injectors free up additional space within the cylinder chamber of your engine. Optimised clamping pad supports provide additional flexibility in the area of the valve train.

Constant performance throughout the service life

The software-controlled Injection Timing Control function (ITC) can dose the smallest fuel quantities for each injector individually, guaranteeing a continuous output over the entire service life.

Minimal application effort

Due to the ITC, no additional sensors or electrical connections are required. Efforts during the initial application and the tuning of the engine are simplified. The ITC function can be activated via the ECU.

Wide range of applications

Thanks to a particularly narrow injector concept as well as its flexibility in design and connections, the LI1 can be easily installed in existing engine compartments. Featuring a large flow range, the injector is designed for engines with a displacement between 1 and 2.7 litres per cylinder.

Long service life

State-of-the-art material technologies, special material combinations and proven mass-produced materials guarantee outstanding resistance of the LI1 to dirty fuels.

High insulation protection

Compliance with the IP6K9K insulation class is guaranteed by the combination of an electrical interface and a special cap. The connector housing is moulded directly to the injector. Further electrical connectors are not necessary.

Precision and stability in mass production

The microprecision parts are identically designed and manufactured across the entire injector platform. Tolerance differences are reduced to a minimum.
