yup EGR

but classical EGR was used primarily for NOx reduction in gasoline engines

on the other hand, EGR equipped with turbocharger will not only reduce NOx emission, but also provide a boost for your engine without using more fuel

plus, additives in the fuels

open air = same oxygen levels
source of ignition = i think its the same (maybe lighter)

hmmm....still differ for 10 secs (petronas & caltex)

Agreed, if done at the same time at the same place, high chances are that the variables are pretty controlled. But I think a fellow forumer this now pointed out which one is for which kind of car. Just don't know how bullshit his statement is.

idk is it the camera's exposure settings + white balance or is it real that the fuel that burns faster has a whiter colour and its brighter, anyone noticed?

haha...

omg, tat means petronas's 1 is not pure de

for me...different is from the engine itself....
this test is not accurate

Different colour due to different chemical reaction by different additives and temperature of burning.

Yes temperate of burning. Directly affected by oxygen level.

i see

So Caltex > All ???

mari belajar ICE

you better watch this...



u better learn this from liang popo

Not necessary, for one, we do not know whether faster fuel combustion means a more efficient energy change (from chemical energy to heat). Also, it is very hard to say that whether faster fuel combustion has anything to do with the energy provided and whether it is cheaper. 1 litre of petronas and 1 litre of caltex may produce 2 different readings of energy provided and energy loss due to the different additives. Also, there will be an optimum condition for combustion too.

Without proper data and knowledge, basically this thread will go nowhere.

quickly burned, less carbon = caltex ron95

slow burning, lots of carbon = petronas ron95

check your muffler tip. after that, you know the best fuel for your car

Just read this article, save your trouble analyzing.
