Motor torque!how to interpret it on ecm titanium?

[alfetta80]

guys I would like to open this discussion with you, then:the motor torque is expressed in kgm or in Nm it in a motor and the force exerted by the gas conbustione on the piston more thrust and strong more' ec couple, of course, the speech is long and there are so many factors to take into account,now I want to add this address to the factor mapping,on ecm titanium on a edc16c8 I am required torque during the acceleration and torque request during the standard terms and conditions how to interpret it??,on the chart I find the rpm,%,and Nm, but as you but he is thinking in this case??the example on the chart I find it to 3500 rpm 100% at 500Nm,raggionandoci the increase of the torque by means of the software can only be done through a greater filling of the combustion chamber and then using those maps, it does nothing but increase the amount of diesel fuel right??or a better combustion and then advance injected???guys thanks and excuse me, but are formed at the beginning I'm trying to understand something........

thanks munro of the resp, the speech is clear,as regards the other maps instead be used to increase only the single i.e. for example, if you increase the pressure diesel fuel, there are no other strategy by the ecu, right?another thing always on edc16c8 that would be the guinea pig that is my car hahaha....I find the map to the quantity of diesel injected increase in mm3, and the map pressure diesel increase in the bar but raggionando a moment, if, for example, increase the pressure, the strategy of the ecu what ?!according to me, knowing quite well the structure of the ecu via a signal in the pwm increases the command to the drv aumentanto so that the flow rate at the inlet of the high pressure pump we, therefore, have more pressure, the more the quantity of fuel injected right?then we say that two maps are equal, and it would be enough to mod a, or is this line of reasoning is wrong??thanks

Explanation the beautiful

[megamind]

But by moving only the objective and leaving the ori, I made the log and nothing changes.

hello munro excellent explanation, thanks!!
returning to the discourse in practice I find quantity of diesel iniettatto in mm3 then I am injection time (us) and' under the I phase iniezzione 1 base map up to four, it seems to me, the increase in e' (deg)what is this map??the degrees of advance??then I rail pressure...

*team electronics:thanks..but are the things you learn leĝera the forum.....
*megamind:I did not understand very well what you have done....the press unbiased ? the press of the map rail that just says the same word ? the goal that the ecu has to keep the high pressure pump....if you change it as you leave ori the press unbiased??
then press the actual does not come to that objective..this ? all another story.....

I changed the lens, but not the map. On the Rail I have 5 tables of rail limiter atmospheric and 3 single values x the objective

alfetta there st? understanding nothing...one thing at a time, please ? well explained....do not believe that I am an electronic engineer, however, eh....what s? I share it for the rest I try to think about for? if not I do understand precisely everything more complicated..
what mappastai talking about??

ok I'm sorry!!!
then on ecm titanium with the usual edc16c8 I'm on the injection system : the quantity of fuel injected f(rpm,trq) (1) then I find injection time (1), then, under I-injection phase - iniezzione main base map 1 (1) the maps are 5... my doubts are these the quantity of fuel injected and the injection time??? these maps are the degrees of advance?thanks munro of patience...

[megamind]

I don't follow megamind...the press objective ? the map are the same thing....and ? only na map the 5 tables which thou sayest I have not ever visteper a map, press the rail much less the limiter, air....
not ? that you confused the map with the turbo??

No No now I try to put the pictures only that I have a mess of things open and I can not...
I on the diagnosis, I can see the goal, whether in the tables rail exchange, the values I pass never the goal, but the arrival of the pi? or less than that value.
For example, if I have 1600 as a lens in addition I do not go, if the limiter rail up to 1660, the goal remains the same to 1600 and beyond, I don't go...if I change the one bit I can, instead, to attach the new lens to be changed and fixed on those individual bits.

hello munro!!!if you can put it the image will be useful to those who, like me, and' at the beginning!!for the rest, the quantity of fuel injected and clear the rest of the floor plan vediamo.una what I don't understand : if you split the nm for a given value ottienii the iq??!!thanks.............
