They refused it because they saw the original design and saw that it could be improved by making it less complicated, which just wouldn't do at all.

For reference, I may be remembering this wrong, but I believe Felix Wankel's first running prototype had the rotor spinning in place, and what we know today as the housing spin with it, inside of a larger, circular housing.

Fake edit: Yup, behold the Drehkolbenmotor 54. Looks like it works more like an oil pump, with rotor and inner housing spinning on offset axes to drive the eccentric shaft:



When wankel saw the revised design he said 'You've turned my thoroughbred into a pack mule!' or something to that effect.

It wasn't just that fan, there were also giant oil coolers and something like 20 liters of oil in the sump.

Even the air cooled 911s had relatively stupid amounts of oil coursing around them- a 993 needs like 10 quarts for an oil change.

If anything 10 quarts isn't enough - my M3's V8 (displacing 4.0L) with its twin pump oiling system required 9 liters of oil. The Viper's V10 displacing 8.4L only requires 11L of oil. This bothers me.

My 6.4L V8 only requires 4.5L of oil and hasn't blown up yet.

The BMW took nearly as much oil because it has overhead cams which requires pumping more oil to the heads. The viper only has one cam and half the valves and rockers to lubricate per cylinder.

What I'm really getting at is a wet sump is not an adequate lubrication solution for that motor in my opinion.

Speaking of BMWs and inadequate oiling. I knew a guy with an E36 that swore up and down that his dealer had a special oil that only needed to be changed once a year despite him driving it regularly. Meanwhile huge clouds of blue smoke came out whenever this thing started up.

I didn't realize and am somewhat shocked that the Viper motor is wet sump. Was/is dry sump an option/standard, perhaps on one of the hotted up varieties, like the TA?

The viper isn't OHC so there isn't really much point. DOHC engines tend to have inflated oil capacities because so much of it is tied up in the heads lubing the cams and lifters and timing chain (if present). I was amazed at how little oil a 3.8 GM v6 takes compared to a toyota 2GR-FE or nissan VQ35.

Corvette is dry sump, but I suspect it's for packaging reasons.

Either way, referring to displacement numbers for comparison is rather odd. The volume of combustion chamber has no relevance to the amount of fluids elsewhere.

That's, uh, kind of the point of having a smart car, this is extremely common in european cities. There was probably a different car parked where the black opel or whatever is in front there when the smart car arrived.

Yeah. I was making my comparison on the basis of them all being large v6 engines in comparable vehicles (commodore, aurion, maxima). From what I can tell, you need more oil for SOHC than OHV, then more still for DOHC, then even more for DOHC with chain driven cams and VVTI. On a pushrod engine the oil is all concentrated down the bottom where the important bits are; the rocker arms seem to be able to live with splash lubrication and not much else. In OHC engines there are spinning bearing surfaces and sliding, close-fitting parts in the cylinder head so oil needs to be forced up there in substantial quantities to keep everything kosher. This seems to be backed up by early OHC engines having head oiling issues regardless of make. M10/M30 BMW springs to mind.

The only issues I see are that they should have backed it in, and I'm used to streets/parking spaces where you're pushing your luck on the available width to do that. They may be short, but they're a lot longer than the average car is wide. Maybe in the states it'd work ok, but around here, a truck's going to take out whichever end is facing the road in short order.
