AVL ConsysLube

OIL CONDITIONING

The oil conditioning unit conditions the engine or transmission oil temperature and supply pressure to a pre-definable set value and keeps it within a certain tolerance at steady state and dynamic operation of the unit under test (UUT).

AVL Approach

The main applications for AVL ConsysLube are engines up to 400 kW (customized solution for bigger engines available). Several connection modes and unit options allow different applications like oil pan conditioning, oil pressure control and pre-heating. For oil conditioning on gear boxes the AVL ConsysLube can also be used.


Benefits at a Glance

  • High control accuracy
  • Easy configuration, adjusted to the respective application due to modular design
  • Quick control response due to a primary controlled media circuit
  • Various integration possibilities into the engine oil circuit (sump conditioning, pressurized oil conditioning, etc.)

Control Principle

The PID control is carried out by an external system (e.g. PUMA OPEN). The temperature control is performed by a mixing valve (heat exchanger/electrical heating). The supply pressure control is handled by a control valve in the bypass between the supply and return lines to/from the unit.


Application

The AVL ConsysLube is installed at engine test cells, single cylinder research engines and gearbox test cells.
Beside the standard temperature range, AVL can also offer modified units for climatic test beds down to -40°C.
