The car actually runs cooler sir...
Because in my country the mixture its 95% propane that boils at -47C so all this cool it's going straight into the cooling system via converter...
All lambda its on 0.9 that is perfect for LPG even on boosted sir, checked via wideband...
In case of the lean...
Well thats nice to know thank you for your knowledge sir.
So the million question...the sound generated by petrol its the same as the lpg?
Did someone in this forum ever tune an ignition map based on knocks?
Old school guys tune the ignition by advancing until can ear the knock and after that...
I know that the system amplifies the received signal in order to make a better filtration.
And i know the system converts an signal that is generated by the knock sensor(voltage) into a factor, everything after that defined factor its considered an knock.
For example this factor its much...
This is what i love when share ideas,
Diferent opinions, and points of few give diferent ideas...i have never check when the ecu looks for knock until today.
Nice point of view
Thx for the advices.
Lookin around at my ecu maps i see that my ecu looks for knocks from 5 ATDC to 75ATDC.
Do you think checking for knocks before the TDC too will be a good thing?
On the groups from my car/engine there are a few with LPG but not optimized in terms of ignition/afr and etc.
But yeah thats what i need to know, if the lpg does knock or not.
"Furthermore, as I alluded, a modern knock sensing system surely "looks" for knock in only a very narrow crank angle...
''Wouldn't the knock signature be the same regardless of fuel, more or less? It is a function of the location of the sensor and the structural properties (resonances) of the head, and the cylinder size, isn't it?''
Thats the real question, can the LPG knock like Petrol if over-advanced? And...
''But then you really need to be recording and processing the raw data, so you can compare knock signatures on different fuels and make sure the time window for knock detection is actually capturing knock on specialty fuels such as E85 and LPG.''
The ECU will record all the data for the...
Hello all,
I'm here to take some knowledge about the LPG and ignition timing.
My car got 2 ignition maps...one named RON91 and another named RON98, RON98 its more advanced than 91 (that is very safe), in normal conditions RON98 its used, and if a knock its detected will happen an ignition...
