There are no valves, no timing gears, no con-rods, no pistons, no crankshaft and only three main moving parts compared to the myriad of parts involved in making a 'normal' engine work. My setup is as follow: S362sxe with 0. the other school of thought is that you want to time the injection on the valve opening to ensure the fuel makes it straight Only available when the Engine Type is set to Rotary. Rotary engines also have a greater mass coefficient, a stronger fuel-air mixture flow, and less maintenance required than piston engines. If say a DO is used to turn power on to the stage 3 injector supply, control them in parallel with stage 2 injectors then use the same enable condition to select a different map or equivalent for the combined injector set? Having Stage 3 support sound much simpler. 8-10. ) and the Kreiskolbenmotor (KKM, "circuitous piston engine"), designed by Hanns-Dieter Paschke [2] (see Figure 3.

As stated earlier, Mazda began equipping their rotary engines with "breakerless" ignitions in 1980. If it were me (the only person to crack a VG30 head that I know of), I would ramp it up from you minimum timing at a certain load point to the maximum timing at that same load point across the entire RPM range, for each load point. This should clear up some of the questions you may Jul 31, 2019 · There is very contradicting info about true tdc for rotarys, there are 2 timing marks on the pulley I have set the ecu lock on on 0 and set base timing to the first mark but then when you unlock timing and recheck with timing light (engine running)it is about 10-15 deg retarded even though the ecu is putting out 16 deg. Oct 23, 2021 · A rotary engine has four separate sections, and each one performs a specific job: intake, compression, combustion (or ignition), or exhaust. tional method of setting the timing - at idle, with the vacuum advance disconnected. Tighten the main dizzy bolt. How Tuning A Rotary Engine Is Different. The engine had a two-rotor design also, the same rotor radius. A Firing Angle of -5 would be used, with a 15 degree Trailing Split Angle. To set the trailing, undo the two adjuster screws on the trailing pot (the one with the slots on it). Additionally, timing just for inspection of parts may take up to two weeks. May 18, 2016 · A good starting point for the ignition timing map is around 30 to 35 degrees in the cruise cells, 15 to 20 degrees at atmospheric pressure and if boosted, 10 degrees at peak boost. If the graphs are tuned for more degrees, it will be limited by this value. com/collectionsInstagram: https://www. Each timing map is completely independent. Sep 28, 2015 · Knock is definitely an issue with a turbo rotary on pump fuel. The key to reliability from the tuner’s stand point however is understanding the tuning requirements are very different on a rotary engine.
