LOL the eye that the nitromethane ? a molecule is obtained by mixing nitro-glycerine and methanol. Nitroglycerine as such ? very unstable, I figured if they put it in an engine
Apart from this pleasant digression, to explain is not ? simple, and I realize that to understand can? be equally as difficult. If we add to this the fact that to explain things are not good, we are ruined.
We feel differently:
Imagine our web portal allows you to a regime any hypothesis-4000 revolutions per minute.
Imagine now finish the injection exactly to the upper dead point.
Hypothesis 1: (random numbers) To burn perfectly the deal? of heating oil that you entered ? need a second 1s
Hypothesis 2: (random numbers) To open the drain valve to the scheme are required to 1.1 seconds (considering when is the end of the injection phase, which coincides with the top dead point)
Result: no problem. Everything is running smoothly.
Let's get in the second case, for example, the injection phase ends 15? ATDC
Hypothesis 1: (random numbers) To burn perfectly the deal? of heating oil that you have entered (the same as before) ? need a second 1s.
Hypothesis 2: (random numbers) To open the drain valve to that regime are still needed to be 1.1 seconds, but always from the upper dead point, that is not the same pi? with the phase of end of injection.
In practice and as if the valve is opened after only 0.9 seconds from the end of injection (random numbers)
Result: the diesel brucer? still for 0.1 seconds after that ? open the drain valve.
Really? the situation ? the worst of it as described because? complicated by a number of factors.
You can improve the thing by throwing air at the storm inside the cylinder, or still better by improving the quality? diesel, by adding molecules that are capable of burning quickly, and by improving the atomization of the fuel.
The motions of the swirl, in their turn, allow to improve the combustion allowing for a pi? effective mixing of air with fuel. Apart from this, c'? little to do
