ULPOWER Operating Manual UL260i UL260iF UL260iS UL260iSA Denomination of cylinders Description of systems Lubricant system The oil is drawn from the wet sump through a coarse filter on the oil pickup tube to the oil pump. From the pressure side of the pump, the oil passes the oil cooler (optional) and oil filter, after which it enters the main oil gallery to flow to various points of lubrication in the engine.
Electronic Engine Management system The UL260i is equipped with an electronic injection and ignition system. RPM and Throttle Position are the main inputs to the ECU (Engine Control Unit). The pre-programmed fuel map in the ECU regulates the amount of fuel that is injected through the injectors and the pre-programmed advance map decides on ignition timing.

ULPOWER Operating Manual UL260i UL260iF UL260iS UL260iSA Note: If temperatures are still at the high end of the limits, permit the engine to cool down by idling the engine for a few minutes before shut-down. Engine storage For long out of service periods we recommend the following to protect the engine against corrosion.
(as stated before) carefully to pinpoint the problem. Check fuel for eventual contamination. Rectify the problem if possible or send the engine for inspection/overhaul to a ULPower authorised service-centre. Any sudden engine stop should be entered into the logbook, stating the possible reason.
On the ground, verify that oil level is sufficient and air is free to flow through oil cooler. If problem remains, the engine should be sent for inspection/overhaul to a ULPower authorised service-centre. Oil pressure below minimum ...
Carry emergency/precautionary landing. If it is not a sensor malfunction, send the engine to a ULPower authorised service-centre for inspection/overhaul. Knocking Reduce engine power setting to the minimum necessary and keep engine temperatures well below the maximum.
