The company will be presenting
injection components for engines in the 1- to 2.7-litre per cylinder power
class. ”Our injection systems have already proven themselves in off-road
applications. The next step is now the heavy-duty on-highway sector”, explains
Maximilian Schaut, Managing Director Sales and Finance of Liebherr Components
Deggendorf GmbH. ”We have been cooperating for some time in this field with the
leading Russian engine manufacturer Kamaz. Today we would like to show the
industry that we’re also a reliable partner for on-road applications",
continues Richard Pirkl, Managing Director Engineering & Production for the
Common Rail Systems (CRS) business unit.
New LI1 injector platform for maximum freedom of application
A highlight at the exhibition stand will be
Liebherr’s new LI1 injector platform. The flexible common rail injectors are
specially designed for use in light-, medium- and heavy-duty engines. Their
slim, compact design and flexible connection dimensions allow for maximum
freedom in terms of engine installation space. There are currently four
different housing variants available. They range from a particularly short
design with maximum length of 90 mm to a consistent housing diameter of 21 mm
and thus provide additional space in the cylinder chamber of the engine. The
built-in Injection Timing Control (ITC) function can be activated via a
software module in the engine control unit. This means that no additional
sensors or connections are necessary, which also minimises application costs.
The ITC provides precise metering of the smallest fuel quantities and ensures
constant injection quantities for each injector over its entire service life.
Efficient LP7.2 high pressure pump
The LP7.2 common rail high
pressure pump will be presented as a further system component for engines in
the light-, medium- and heavy-duty sector. The oil-lubricated roller tappet
pump is particularly small, lightweight and compact in construction and,
therefore, easy to integrate into existing engine compartments. Digital inlet
valves control the fuel supply. The special design of the pump keeps energy
loss and dead volume to a minimum, with a corresponding increase in efficiency.
Flexible LI2 injector platform for demanding applications
In addition to the new
developments, Liebherr will also be presenting the LI2 injector platform, which
is already in use in demanding off-road and heavy-duty on-road applications.
Here, too, the application flexibility is convincing. For optimal integration
in a wide range of engines and applications, variable housing geometries and
nozzle variants are possible. In addition to the classic 7 mm nozzle, the
portfolio also includes a 9 mm version, which achieves particularly high flow
rates.
Microprecision parts for hydraulic components in mass production
The microprecision parts form
a link between the system components of Liebherr's common rail systems. The
Components Division manufactures most critical components in-house. This
expertise allows for a flexible response to individual customer requirements
and maintains the usual high Liebherr quality in mass production.
