Fully equipped gas engines
Liebherr gas engines are distinguished by a high degree of efficiency and availability. To safeguard these attributes in the long-term, the engines are supplied fully equipped. This equipment has been optimally adapted to the engines and offers a “plug & play” solution. All components have been validated for the engines and extensively tested. Straightforward integration in the system saves time and money.
Gas engines by Liebherr: Basic equipment at a glance
Wiring harness with sensor technology
Liebherr gas engines are supplied fully wired. All of the seonsors are already integrated in the wiring harness and therefore in the engine. This increases product safety as well as service-friendliness.
This compact unit with integrated actuators controls the speed and output of the engine by regulating the volume of the gas mixture. The valve is adapted optimally to the engine and offers an ideal mixture for operation.
The modern ignition system is integrated optimally in the engine concept and contributes towards steady ignition and thereby a high degree of efficiency. The air-gas mixture in the cylinder is ignited externally by a spark plug. The ignition timing and ignition energy are freely adjustable for ideal combustion. This means safe operation of the engine is assured without misfiring and knocking.
Two-stage stainless steel intercooler
The stainless steel, two-stage intercooler is designed for natural gas and biogas. It ensures maximum energy recovery as well as a long life cycle, therefore reducing maintenance intervalls and costs of service.
The turbocharger was especially designed for gas operation and ensures that the engines run steadily and highly efficient. All Liebherr-engines feature one-stage turbocharging.
Compact design, with integrated actuator valve and venturi, enables high resolution lambda settings. Flexible means of application are enabled by the modular venturi structure.
The basic engines impress with their sturdy design. They are tried and tested under tough conditions.
Efficiency based system integration
With a mechanical efficiency rating of over 43%, gas engines from Liebherr offer the best efficiency values of their performance category. This value is the result of many years of application experience, careful selection of components, intensive development work and also a high degree of system integration in the area of hard and software.
All components have been carefully selected and optimally adapted, tested and validated for the engines. Fine calibration for adapation to the specific applications is very straightforward.
In addition to starter, turbocharger and two-stage charge air cooler, a variety of other options is also available.
Reaching from coolant temperature sensors to ignition signal sender, Liebherr gas engines include a variety of electronic sensors. All sensors installed in the engine are supplied wired. For installation in the system, they just have to be connected to the control unit.
Software and engine programming
The supplied engine software already contains all of the requisite parameters. With the carefully validated and adapted values, the performance values of Liebherr engines can be achieved reliably. At the same time there is enough scope for fine tuning in the field.
