yes it is. and which reminds me, better apply for 24h computer lab access, need to do dat matlab assignments.

unfortunately i'm actually doing something. assignments, they're all due tomorrow! =(

so. meteor shower tonight, 22nd april. true or false? technically tmr night?

i had a black car before, never again.

looks good.

i'll be graduating this year, so i might be there, but still up in the air mang. i'll be there if i can find a jerb. get my TR/PR application approved and shit.

well, burning both fuels at atmospheric would be very different to burning both fuels under cylinder conditions, cylinders have pressure between 160 to 200ish psi? that's from 10 to 15x atmospheric pressure. mr aero engineer, any input?

Nah Adam, ethanol does burn slower than petrol. It also burns cooler due to the hydrogen bonds in etOH, which requires a lot more energy to vapourise than petrol. Explains the lower EGTs when running etOH huh? Fact in point is bubble point of etOH which is only C2 is 70degrees, it is a trend that the more the carbons, the higher the bubble pt (high school chem i assume). Petrol is basically C8, with various isomers and aromatics added in to increase octane rating, but they all have roundabout 6 to 8 carbons, and no oxygen in the molecule itself. Petrol itself boils at 90degrees, but the components are largely C8. We can look at vapour pressure and heat of vapourisation to understand volatility. 896kJ of energy is required to vapourise 1kg of EtOH vs 298 for octane, which is the closes to petrol. This, is why it burns cooler and slower. Or at least why i understand it burns cooler and slower. I'll have to look up activation energies to further explain why etOH burns slower but i cbf now. And that is why, it is probably better to go a hotter plug when you're using etOH as a fuel.

where?

more like, the hotter and bigger spark is due to the larger gap, thus larger arc and ionisation of gases. but i would assume a bigger voltage is needed to be able to form the arc across the gap, thus when coilpacks are worn, or ignition system is bad, bigger gapped plugs would show moar misfire.

stretching the distance means a hotter higher spark. increased ionisation of the gases means also a more complete burn, a smaller gap will mean a smaller spark, and thus, less complete burns?

well, try not to lead the other girl on too. unless she's hot, then, you know, by all means, carry on.

feeling better nao borci?

WHY SO MANY YELLOW 34S NOW????

and bronze always look good. most versatile color imo. black too.

lol vego.

b16 yo, do it. vtec will kick in.

you got a silver car? YOU NEED GOLD/BRONZE WHEELS.

went from a 32R to a soarer. REGRET. should have gotten another 32R.

use a big one.

yes.

you should get into a gt-r next mate.

he didn't turn up to be belted.

i dont even lift. dat 69kg dere.

hmm
