Versorgt schon jemand von Euch die Rotoren des Rx8 mit seperatem Öl?
Ich möchte hier eigendlich keinen neuen Öl-Thread anfangen, es sei jedem selber überlassen, welches Öl er wo und wie einfüllt.
Jedoch würde ich den Vorteil darin sehen, dass nur "sauberes Öl in die Rotoren kommt" und man ein Öl verwedenden könnte,
welches ideale Verbrennungseigenschaften hat.
Und hier der Benötigte Adappter, extra für den Rx 8: (der Text ist Rx7 lastig, der Addapter auf dem Foto ist aber eigens für den Rx8)
Oil Metering Pump Adaptor
Wankel engines such as the one used in the MAZDA RX7 sports car need oil in the combustion area for lubricating the metal seals.
Most stock engines use a metering pump pumping a small amount of engine oil from the oil pan into the intake manifold and/or directly into the combustion chamber. Engine oil is designed to lubricate sleeve bearings and carry heat from the engine interior to some cooling areas. In the RX7 the heat is removed from the oil in an oil cooler. When engine oil is getting into the combustion chamber, it only is burning partially, leaving some unburned deposits behind. These deposits can build up and reduce engine performance.
One obvious method of preventing this is to disconnect the metering pump altogether and mix two-stroke oil to the gasoline like some older two-stroke engines require. With this method it has been demonstrated that two-stroke oil is an effective lubricant and there is no build up of combustion residues.
The Metering Pump Adapter, as offered by PCV Technologies takes the solution one step further in allowing to still using the stock metering pump but supply it with two-stroke oil. This adaptor pump is installed in conjunction with the stock oil metering pump.
With the Adapter installed, all that is needed is a small oil tank with two-stroke oil (you supply the two stroke oil reservoir tank), connected to the Metering Pump Adapter. The oil level in the tank should never be less then 6 above metering pump.
Oil consumption is approximately 1/100 of fuel used.
Adjuster for 3rd Gen and Renesis Gen Rotary Engine OMP
The 3rd gen RX7 engine is popular for use in experimental aircraft Using the OMP for top lubrication is an open question, because most after market EMS do not provide an output for OMP (oil metering pump) control. In the RX7 car, the OMP oil flow is controlled by the engine RPM. The pump rate control is activated by the car computer. This pump rate control is used to increase oil flow where there is an increased power demand at LOW engine RPM. This condition generally does not occur in an airplane (as we run at higher RPMs all the time). When the engine is used with an EMS with no output for OMP, the only option is to mix some oil in the fuel for top lubrication. The preferred oil used for this method is two stroke oil, due to its ability to readily mix with gasoline and lower combustion residues (when compared to regular engine oil). To overcome this draw back in aircraft used, the OMP pump rate can be fixed to a certain position and the oil flow will only change with engine RPM.
The RX7 OMP is controlled using a position stepper motor. The stepper motor may be replaced with an ADJUSTER to set the control shaft to a fixed position. In this way, the OMP is fully functional, giving an oil amount comparable to mixing the oil in the fuel. If the use of two stroke oil is desired, the ADJUSTER with the PVC OMP ADAPTOR provides a completel two-stroke-oil conversion.
