new rotary engine trouble ?

Mar 25, 2006 134 Replies

I've driven a 300M - the FWD 'predecessor' (only the 3.5 V6 is shared), and by god, that thing could handle, especially for a big FWD beast. I also used to drive a W124, the car that I think really donated a lot of the underpinnings to the LX platform (Magnum/300-C/Charger), and it was relaxing, smooth and capable - and when pushed, it really handled very well, if the actual body control was poor. Mercedes and Chrysler aren't silly about chassis engineering.

What people expect of a car here is a bit different, but I drove the MG ZT260, and it was harsh at low speeds. Too harsh. Worse than the RX8. I don't want harsh, the roads around here are like a bloody warzone and the 2CV is worrying enough on them.

I want my V8 unstressed and lazy, keeping me going at relaxed, pretty legal speeds, unless I want to pass something right now. If I had 30K and wanted a sports car, I would buy an MX5 or Elise or VX220.

I had the hots for a Mazda vehicle with a rotary engine, but decided against it when the price / series of available cars exceeded my budget. Was never really serious tho.

But in searching for info on the rotary engine (very interesting / informative) I saw where there is an engine plant being constructed in China - just to manufacture - rotary engines for use - world-wide.

Heh. Last time I was in NYC I was waiting to cross the road when one pulled up at the lights. It's not often I've stood motionless, mouth open, thinking "what in the name of all that is holy is THAT?!?"

Actually, it happened twice that trip - Aztek and Cayenne....

I like the look of the 300C in a poor man's Flying Spur pastiche kinda way.

The message from Adrian contains these words:

Nice to see the AMC Pacer project is still leaving its mark!

And as for sweet dreams - I've just been woken up by a stray cat hammering on the catflap. Some visiting kid had locked it and the cat had got in but couldn't get out.

Its a beautiful car. That's the wonderful thing about opinions- you're entitled to hold a silly one :-)

One of the big car magazines was doing a "shootout" style road test and comparison of several of the high-end (~80,000 US dollar) 450+ horsepower luxury/performance cars recently. A BMW 7-series with a V10 and the Chris Bangle styling from hell, One of the new-style (looks like a turtle after an encounter with a semi truck) Benz's with the 5.4 Kompressor engine, one of the angry window-AC styled Cadillacs with a supercharged Northstar. At the end of the test, another group from their magazine showed up at the track with a Dodge Charger SRT-8 (same chassis as that 300 you're ragging on) and its normally-aspirated bone-stock

6.1L Hemi. So they added a sidebar to the comparison article titled "And for about $40,000 less..." in which they ran the Charger through the same tests (road course, 0-60, 1/4 mile, etc) that they had just done with the high-enders. It posted very similar numbers, in fact beating the Cadillac (by a LOT) on the road course and coming within a few 10ths of the others, and beating one of the others in the quarter mile. I'm sure Cadillac, BMW, and Benz were pretty pissed at the magazine for that one, because the immediate conclusion was "why would ANYONE buy one of these overpriced ugly-ass monsters when THIS is on the market?!?" Well actually what they SAID was "you could buy the Charger AND a Honda S-2000 instead."

You guys just need to slide behind the wheel of one of the Hemi powered Chrysler LX-chassis cars before you write them off so casually.... else you'll end up looking at its taillight

I understand a wankel type engine for aircraft use is under development by Mistral Geneva Switzerland as reported by Tribune de Gen=E8ve on 28 March 2006. RW Bonhoff retired Civil Aviation Consultant 15 April 2006

Speaking of 5W-20, the Mazda went blotto on the stuff. All rotaries supply oil to the combustion chambers to lubricate the rotor seals. The RX-8's new Renesis rotary has a computer-controlled injection pump that is supposed to meter out about one quart every 10,000 miles. For some reason our RX-8 guzzled one quart an average of every 3600 miles, demanding a total of 11 extra quarts and drinking its sump dry enough to flash the ominous low-oil warning on no fewer than five occasions.

Above is from part of that C&D article.

Therefore, since oil is injected into the cylinders along with the gas-air mix, that makes it essentially a 2-cycle engine with valves????????? :screwy:

Any car is unsafe; airbags etc. merely reduce the level of danger.

safe is not a word which should be used in the comparative mode - safe "kann nicht gesteigert werden"

wish I had a mazda 8 - low-ash motor oil by texaco / chevron is available.

seals seem to be the most mentioned problem with mazda, but they will overcome it.

I read that China is building an engine factory to produce nothing but rotary auto engines, to be sold - to the world market.

well, I'd settle for a new dodge magnum, they are so ugly - they're attractive.

Oil mixing with the fuel has NOTHING to do with whether an engine is "2-cycle" or not. Whether an engine is 2- or 4- cycle has to do with how many distinct phases of the combustion process exist, and whether they're cleanly divided into intake-compression-burn-exhaust, or whether they blur into exhaust/intake and compression/burn. There are plenty of

2-cycle engines that don't mix oil with the fuel (Detroit Diesel, EMD, Napier, and Fairbanks-Morse diesels for example.)

The Steve entity posted thusly:

4 cycle: Suck, Squeeze, Bang and Blow.
