The Four Stroke Engine...
« on: July 29, 2017, 10:23:02 AM »
Okay, so each of a four stroke engine's cycles is described by the significant action occurring in each, to wit:

Intake - fuel/air mixture is drawn into the cylinder as the piston goes down
Compression - the mixture is compressed as the piston goes up
Ignition - the spark plug sparks, exploding the compressed mixture and driving the piston down
Exhaust - the leftovers from the combustion process are expelled through the exhaust as the piston goes up...
...and the process repeats...

I'm thinking that more descriptive terms could be applied to each cycle...

Suck
Squeeze
Bang
Belch
Repeat

Ignition ("bang") isn't a stroke, although it's a significant action.  I've normally seen that referred to as the Power stroke.
Perhaps "shove"?

Hmmm..
I was clearly not prepared for a thorough assessment analysis...
So... Suck, (Intake), Squeeze (Compression) and Belch (Exhaust)" are okay..
(Crickets)
I'm thinkin' "Power Stroke" doesn't quite fit the overall intent...
Shove...
That would mean 3 of 4 strokes begin with an "S" resulting in the need for a significant counter-balancer...and too many SSSess for me...
Although "Rapid piston acceleration via expanding contained volume volatile fuel air combustion" is kinda catchy...

How about "Blam!" or "Boom", which also goes nicely with Belch.... well so does bang..

 :clap:

Any other suggestions for the 4 stroke Otto engine semi~simplified?

Intake, compression, power, exhaust...
Perhaps a cold brew would ease your mind...you seem wrapped pretty tight over this whole affair. whoohoo1

Well, Wankels still go through all of those stages. They just do it all in a single revolution and burn more oil in the process!  brno

Ah yes, now for a completely different topic.. the Wankel...
Actually, wasn't there a Suzuki MC made way back with a Wankel?
If I recall correctly, it looked like it belonged to George Jetson.. or his boy Elroy, maybe daughter Judy... But probably not Jane, his wife....

I have seen references to a Wankel MC, but haven't actually seen one. It seems about as far from American v-twin "potato potato potato" as you can get! :joker:

When I test drove a first gen RX7 years ago, the word that came to mind was "turbine", but I guess Leno already has that base covered.

Google just found it for me.
It was the 75/76 Suzuki RE5.

I remembered seeing one in a Suzuki Dealer's showroom, and it had the factory fairing on it which made it look even more bizarre...

IIRC, there's a bar in Myrtle Beach called "Suck Bang Blow".  Supposed to be quite popular during bike week.  Apparently they have a burnout pit inside, and burnout competitions.  Look on youtube, several guys burnout till the tire blows.

A bar with a burnout pit inside? 
With enough alcohol, concentrated burning rubber might be tolerable, but hopefully they have a way of getting rid of the exhaust too...
 whaaaat3
I guess I just can't understand why someone would want to do burn outs on a tire, blow it and then walk home...
....unless maybe an impressed unattached can be persuaded to give the guy a ride home (But I wrecked my bike for you!!!)
 haphap
Call me old fashioned, but I prefer rubber on my rim rather than on the ground.. and I always thought that burning rubber was an advertisement for "I'm proud of my lack of traction"...

Okay, sorry, I got carried away and rained on your post....
My bad.

I had a high school job selling ceramic tiles in a high-end shop.  There was a bike place across the street that I used to hang out in when business was slow.
One Saturday they had a big fair with all kinds of giveaways, and they also had a portable burnout pit.  I'd never seen that particular lunacy before so I wandered across to see what was going on and, since I had a passing familiarity with the guys who worked there, they told me a bit about it.  Riders had to pre-register, and their bikes were examined for safety as well as verifying that the rear tyre was approaching the end of its life.  The riders paid for a heavily-discounted new rear tyre that would replace the crowd-pleasing blowout one.
All well and good, until some random rides up after the event is over and, before anyone could stop him, proceeded to smoke his back end until it exploded.  Most of the crowd seem to have realised what was happening and that the owners weren't expecting him to be there, and didn't want him there.  He couldn't understand why the place wouldn't give him a new tyre for free.
So he was stuck with either walking home, or paying for a replacement.  Being a Saturday they charged him weekend labour rates on top of the cost of new rubber.

Not raining on my post DD, I've never been there myself.  My brother has, and I've seen the videos.  From what I see, it's "inside", but they have garage doors open so its more of a patio feel to it.  https://www.suckbangblow.com/
