I must of missed it..... where did you score the bike? I left my girlfriends apt one day and there was a 2007 Giant Rincon laying next to the dumpster with deflated and removed back wheel, crooked handle bars, locked up rear brakes and the shifters looked like they had been through it, but I picked it up anyway. So far I've put it back together, bought a $3.50 tube, straightened the handlebars (they weren't bent but out of alignment per say) and now I have a bike with three working front gears. Considering replacing the shifters so I can fix the rear brakes and shifting. Sweet!! Thats thinking with the right side of your brain! Lefties do think with the right side of their brain

Sounds interesting but pointless to me. 2 more strokes with little to no work is a HUGE waste of energy and increased wear on components. You want to keep heat in the combustion chamber to increase efficiency and promote exhaust velocity. I'm not too knowledgeable on diesels but combustion works the same way and I would think detonation and pre-ignition would both be injector or fuel issues on a diesel. Pre-ignition would come from a leaky injector or a bad (early) timing cycle. Detonation would present itself due to not enough fuel, again, bad injector cycle. Increasing compression will also increase the heat possibly causing pre-ignition or detonation. The only way to prevent that would be by adding fuel. It happens during the compression and power cycles so I don't see how cooling the cylinder after the fact will do anything, hence the reason you see water/methanol injection systems being mixed with combustion air. IT's like plugging someone's ass right after they fart. Good luck though Well its all theory and assuming all the steps to prevent pre-detonation have been taken. or to remove heat from the combustion chamber prior to compression like with a six stroke design You could consider it the first two strokes if you wanted as it really doesn't matter if it comes before or after as it will always come before another compression stroke. And yes, I think it wouldn't really work either. Who knows, it could work really well as a cruising operation point and when valves are able to be controlled with out a camshaft it may be a viable option.

It looks like water will be the best bet. We are looking into "designing" a six-stroke cycle engine for diesel engines. We wanted to add an additional injector and port to inject a liquid on the six stroke to absorb heat and expand to get a little bit of work out of the stroke. The additional port will be an exhaust for the liquid (now gaseous) that will go through a heat exchanger, condense back to liquid state to be re-injected later. The whole point of this design is to reduce heat in order to increase compression or some other design point to increase efficiency as well as get a bit of work from the extra strokes for more efficiency. From my research it looks like a water/glycol may be necessary to prevent oxidation of aluminum components in an engine. The glycol mixture will be kept to a minimum as it reduces water's effectiveness to dissipate heat. Not sure how small amounts of glycol would react being injected directly into an engine or if that would have some kind of consequences if the residual glycol was combusted in the chamber on the following power stroke

Doing a little research for a class project. Do any of you guys know a safe product (like water) that readily vaporizes and expands but does not combust under high temperatures? One that absorbs more heat and expands more than water is more advantageous.

Cheap shifters don't shift. Is it the derailleur or the actually shifter/brifter? Its really the line between the shifter and the derailleur that is messed up, but the shifters were bashed up pretty good so i figured they were cheap enough to totally replace. I really need new lines too
-
I also figured while I'm working on it I would replace the brake pads/ brakes.... any recommendations?
-
So I spent a little more time with the Giant Rincon that I found. I spent $3.50 on a tire tube and now I have a bike with 3 gears and a front brake. The rear gear shifter is fubared so the rear derailleur keeps it in the top gear (smallest sprocket) at all times. I also found out it is a 2007 model and while riding I found out the front shock actually does work. I was looking on the internet and I can get a new set of shifters for about $28. I was highly considering getting them and having a nice cheap bike to ride around.

I really am considering getting into the tablet market with a nook color. Its android powered so you can have an android/e-reader with the same processing power of a Droid 2 but with a 7" screen. I could use it to look at notes and stuff during class, and all kinds of other pointless activities
-
However, with my connection at the local auto parts store our parts are all dealer price and sometimes they are considered "returns" and are free.

I just looked at suspension mods for my Saturn... I should run.... fast

effffff you!!!!!!!!!!!

Just watched 127 hours...... whoa

Wondering if it would be worth it to get steel braided lines....
-
Just finished changing the brakes and rotors all the way around in my truck. Decided to do the back rotors too. The pedal is a lot more firm now. We will see how much better they perform in more extreme situations once I give them more time to break in.
-
Tire size, vehicle weight, aerodynamics (spell check?), or any other number of factors. How big is the difference? J 2 mpg's Just seems like with the 535 being the "bigger" car it would get a little worse gas mileage.
-
Why do the 335i and 535i make the same horsepower with the same engine, but the 535i gets better gas mileage?

what sort of camping stuff? Campmor normally has some pretty good deals, but if you want high end stuff there are better choices. My friends talked about there, sierratradingpost, rei outlet, and campsaver. Not sure what range I'm looking at for now. I know my friends back pack he got for 120 is on sale at camp more for 80 now

Was a chevy right? 02 silvy 6" lift
-
Anyone know where there is a good selection of camping stuff?
-
Yeah, I was going to go steel braided lines, with new pads and rotors. Still undecided on rotors though
-
So finding steel brake lines for my lifted truck and brake stuff is proving to be a bitch...
-
Didn't think they did squat. Why not a new mattress if you are having troubles? I was thinking along the same lines. To me, they are really only useful when the mattress can not be changed. (i.e. Dorm) or I guess if you were in a money pinch

For once I'm actually caught up at work and really don't have anything to do. Guess I'm going to leave.....
