The engine oil filter on the 09 is of extremely high quality fine filtration type in order to prevent problems in systems like this. It should not be substituted for anything questionable for the task. An engineer at Mazda told me that and I think I remember it correctly.

Paul.

 

yea i actually think thats in the '09 owner's manual too, altho it might be some other manual.

i have a cutaway pic and info on the filter somewhere too, post it after work.

kevin.

 

Cool. I have the new filters here but didn't want to sarifice one for curiosity sake at this time.

Thanks Kevin.

Paul.

 

They don't have any Micron filtering specs for them do they Paul. Compared to the prior years filters? Are the new filters interchangable with prior years. I know the mount location is different, but is the filter mount?

 

when speaking of the OMP you need to realize its a positive displacement pump. It will deliver the same amount of oil with zero back pressure or 300 pounds of backpressure. Therefore clogging is less of a concern, and changing oil weights has no effect.

 

So you mean the new filter has higher than 99.99% filtration rate ? (cuz some filter claim to have 99.98%)

hmm. maybe I should use it ? ( I still have some filters left, OE and aftermarket)

 

Sorry, coming in late here...as usual

On Paul's pic....

Well it really is just a manufacturing parts super-session done by Mazda, so they cast ALL the RENESIS 13B housings to the latest series II set up with 3 nozzles per housing, but do not drill the 3rd hole for Series I Engines....no big deal, Mazda do this all the time, it makes sense a they only have to 'cast' or make one rotor housing.

From a selling/retailing point Mazda obviously still has 2 different types of housings, one for Series I and one for II. N3H1-10-B10C and N3R1-10-B10.

Yes you could drill the 3rd injector into this housing "pictured", but WHY would you do it, you might as well just buy the Series II N3R1-10-B10 Housings as the job is already done for you.

As far as drilling the hole on an "assembled engine"?, how are you going to guarantee that no debris will fall into the rotor chamber?

Then there is also the issue that the Series I Stepper MOP won't handle 2 more extra Nozzles, it does not have the capacity to deliver.

Forget trying to add the two Series II Electromagnetic MOP's, you have issues of wiring, PCM , OCV (oil control Valve) ,Oil Pump, and the critical one OIL PRESSURE, the Series I does not have the 50% extra oil pressure needed to operate this new system.

Mazda have completely overhauled the MOP system on S2's.

Rough cost to buy all the parts about $2K , that does not include PCM (1K) and Wiring looms, new oil pump, that is if you can get it to work.

Good find Paul..

 

If someone wanted the 3 rd nozzle housings (don't ask me why), why not just sell the S2 housing?

N3R1-10-B10

 

The new system on the Series II does have an oil pressure sensor on one of the two EMOPS for monitoring oil pressure to the EMOP's, but not as far as I know on the Stepper MOP on S1.

 

The new system has a self cleaning mode that shoots the crap back down to the sump, but yes, I don't know how they clean the filter in the injector...I cant see it is possible there at all to clean at this point..

 

Yeah, I have been saying for ages to not use any other type or larger filter, perhaps that is why Mazda put that semi-circle type alloy flange around the oil filter to stop anyone from changing to a larger diameter filter and to protect the filter body.

I can see no reason why a S1 owner could not use the S2 oil filter.
Remember that the S2 does run a 50% (approx) higher pressure oil pump.

ALL 6 Oil Nozzles are the exact same type and are new and unique to the new EMOP System.

 

NEW OIL PUMP DETAILS

 

LMFAO, i was gonna post the '09 service highlights pages too as there's so much info on it. But there's a good cutaway, outline cutaway at least, with decent specs on the filter. I think i have another paper on it too

kevin.

 

Good info...looks like a much different system

Good thing I suspect

 

?..


As I see it the new EMOP set up is somewhat incorrect (in description) as the two EMOP's are not really Pumps but Electromagnetic Actuators, the actual "Pumping" of oil is done by the engines main and only New "OIL PUMP" with the Oil Control Valve maintaining supply to the two "Actuators", when they receive an electric current via the MOP Driver the Electromagnetic Solenoids main centre Plunger Opens allowing oil to flow through to the Injector Nozzles.
When current is turned off the Plunger closes oil supply.

So the EMOP's are not actually Pumping anything they are just a gateway or controlling chamber Opening and Closing Plungers to allow oil flow.

Does this sound correct?

Ash

 

Hmm ... self cleaning .... hmm

 

Good luck "self cleaning" those filters.......

 

Ash,

I was wondering where you were. You probably would have given Zoom a run for his money in how quickly you could have figured out the oddity of this housing. By the way, I didn't buy them in order to provide the 3rd nozzle option; that was a pleasant surprise to me. I can't as yet guarantee that the N3R1 (09) will work the older parts though and it retail in the US at almost $1000 (Although I can do better ).

Paul.

 

my oven is self-cleaning too....and its dirty as hell. food for thought.

ASH8: As far as specific wording, the Service Highlights line of mazda books has a tendency to have grammatical errors, phrasing errors, and some "old" pics in it. These eventually are amended before the release of the next service highlights book. The manuals are pretty constantly updated, updates just are only released at specific times and their is no notification of print/image changes.

glad to see everyone getting some use out of that file someone else posted.

kevin.

 

That's the way i see it.
Engine oil pump creates flow. OCV regulates flow rate. EMOP is just a valve to turn on flow to the side and center oil injection nozzles during engine operation.

By the way this is some great info.

 

got to watch Zoom

 

I agree with you guys that it make more sense they way you describe it, but if you read the section below carefully, it would seem not to be so.

The way it describes it then there is no power applied to the oil metering pump, the oil pressure in the oil tube is greater than the oil pressure in the oil metering pump, the sub plungers are retracted, and oil fills the space between the sub plungers and the oil tube check valves.

When power is applied to the Oil metering pump the the main oil plunger pushes the sub plungers towards the oil tube check valves, forcing the trapped oil in front of the plunger through the check valve and into the oil tube.

The Oil metering pump driver must pulse the power to the oil metering pumps, so when there is no power to the oil metering pump the plungers reset and oil fills the space between the sub plungers and the oil tube check valves, and when the next power pulse the plungers force the oil through the check valve into the oil tubes.

Thus increasing the oil pressure in the oil tube to the point where the oil nozzle check valve is forced open and oil is discharge into the engine.

At least that's how it's discribed in the section below, which means the oil metering pumps, are actually pumps, and are rapidly and constantly cycling.

I would have thought the way you guy described it made more sense, where the oil metering pumps and oil nozzle are acting almost like fuel injectors, no power oil is blocked from entering oil tubes, power applied pressurized oil is allowed to flow into oil tubes and exit oil nozzles. (or even the oppisite where when no power is applied oil is allowed to flow to the oil nozzle, and when power is applied it is blocked the flow of oil, which would make the oil meter pump fail state to feed oil in the nozzles constantly).

It's all a little confusing trying to understand the way they describe they did it.
