hi, i still got 3 months to my permit and 8 months to my license but i am very interested in learning about rotaries. please don't think, "oh great, another 15yo kid who's ignorant and wants a rx7 because of tftf." i'm not like that. i just want to learn more about rotaries since they are so much diffrent from piston engines. i have had good experience from learning in forums (nico, freshalloy, zilvia, nissanforums, etc) so i decided to learn from here.

i've been to howstuffworks and whatnot, reading on how rotary engines work. i understand the basics of how the rotary works and undersatnd somewhat how they are different from other internal combustion engines with pistons.

i have read that rotaries have a much more complicated vacuum/pressure system. i do not know much of how the vacuum/pressure system works on the rotary.

i have noticed that you guys use wods, "vacuum chamber, pressure chamber, all kinds of valves, actuators, solenoids, vacuum hoses, TCA, CCV, CRV" and what not. could somebody explain what those are and how they work? if not, give me a link that i could read up on?

i know it's a lot to ask but it'll be greatly appreciated. thanks a lot guys

 

bunch of emmisions and turbo control crap
thats all

most/all can be removed and simplified

 

This stuff was added, because a rotary chucks out a load more emmisions than a "normal" engine does, otherwise it's virtually the same to a piston engine.

the best advice I can give you is to buy a workshop manual, and try to learn as much as possible from that - it shows where everything goes, and explains (breifly) what some of the items do since they're not common on piston engines, and mechanics need to know what bits do what, and WHY.

After you've a had a good old read, then you'll know what to search for on this forum to gain more knowledge about these fantastic engines.

Well....

thats MY opinion anyway

 

The rotary is FAR superior to any reciprocating piston pumper. The smoothness, sound, and power delivery can't be beat. And the size/dimensions would put any boinger to shame.

 

There's only ONE thing that a piston engine can beat a rotary on.........



Sheer levels of torque!!

 

thats what a turbo is for

 

im new to rotaries also. How much does it cost a year to keep the 7 mainteninced (sorry about the misspelling)

 

depends on the generation

if its a fb,fc n/a
not much really
the turbo II generally cost a bit more

the fd is a maintaince hog

 

oil, sparkplugs, air filter, oil filter, fuel filter. much else needs replacing on a regular service (sounds like any other car really)

 

If you want to learn rotarys really well just stick around this forum and the others and read up. I've only been here a couple months and I already know the answers to the most commonly asked questions (that get asked over and over and over and over...) Also check out the archeives of all the forums, they are usualy the most information rich threads ever posted. It is a rumor that RX-7s break more often than piston engines, they are just more sensitive to poor care and with the exception of the FD most of our cars a getting old. old cars have parts that break more often, so you might have to fix it more often. thats all.

 

And the myth that they won`t go over 100,000 mi is a joke too, ours has 275,000 and going strong!! (proper care)

 

agreed
but 200,000 is where most tend to die

 

I've got a clasic mini with 165K on the clock, and it hasn't had an oil-change for almost a year now, yet I can STILL beat almost any car that want to race me.

Goddamn I love mini's!!


That was a hijack, but hey

 

cool cool thnx for the info

 

Yes, but stick a turbo on a piston and you have the same effect blah blah blah...

Just had to play devils advocate for a sec

 

yo dude im only fifteen two. do what i did stick around the forums for a while and you will learn a lot.

 

pfft
rotaries can spool GIANT turbos

 

just for the record, a rotary will last just as long as a piston, if maintained properly.. mine has 220K+ on the clock when i tore it down (christmas break)... it really didn't need an overhaul... (tore it down because the history of the car is unknown to me)

 

42

 

And big-displacement piston engines can spool FREAKING HUGE turbos.

OK, Ok, I'll stop.

Besides, the piston engine wouldn't be nearly as sexxy doing it
