This is handled by: - measurement of engine temperature ( cooling water temperature ) with sensors - control of water flow in cooling water circuits via pumps and valves - control of cooling of engine via fans and radiator shutters For each of the sensors/actuators diagnostics are provided. 2) Engine Lubrication ( ENLU ) The main objective of the AGGR ENLU is lubrication/cooling of the combustion engine and service interval calculation for engine oil. This is handled by: - measurement/modeling of oil temperature with sensor or by model - control of the oil pressure via oil pump - control of piston cooling via valve - calculation of time/distance until next oil change For each of the sensors/actuators diagnostics are provided.
