Hello Pat,

Eric ,

In my situation , injecting gaseous lpg at coolant temperature , that would mean I don't need any accel enrichement at all .
The gaseous lpg cannot stick to the walls and valves as it can only return to liquid stage by cooling it below freezing point , or pressurizing it above ...

Hello Werner,

Pierre

The L-jetronic also has acceleration enrichment. It uses the inertia of the air meter for enrichment and on some cars there is a sensor that turns on enrichment anytime the MAP changes downward. This is what the sensor looks like.

Hello,

I have a fascinating writeup on my thoughts about AE in this thread:

http://www.msefi.com/viewtopic.php?t=13851&highlight=

It outlines the only reason I can think of for AE, outside of user-imposed pneumatic limitations on the MAP sensor's reaction times (read: long, thin MAP sensor ...

Hello,

I am fighting right now with my accel enrich setting (can get the car running as smoothly as the stock L-Jet :evil: ).
But after a lot of thinking, I don't see why an efi needs that feature??

For a carburated engine I think that the reason is the bigger inertia of fuel vs the one of air ...

Also- timing comes before fuel, because advancing timing results in lower EGTs, meaning you can run leaner (but still rich), wich makes more power and saves gas. Too advanced timing results in reduced power, or engine-destroying knock.
While timing and fuel are definitely iterative, I must say the ...

I wish. I have only seen a hard copy of it at the library (the old way of doing research ;) ).

I'm sort of crappy at explaining myself, I'm sorry about that.

If you don't touch the ignition timing, then yes, AFR will have a big impact.

That was my case, MS is only controlling fuel. Maybe it ...

Hello

Pierre -
I suppose their might be specific circumstances where the AFR is doing some things in one specific engine it isn't doing in other engines like changing the way the air flows into the engine.


I don't understand your answer. I don't think that AFR change the way air flows into ...

Hello,

You might not believe this, but given correct ignition timing, let the AFR vary between 12.5 and 14.0 and you will see an almost indistinguishable difference in engine output! This is based on a paper published in the 1930s for NA engines that still holds true today. AFR is but a thermal ...
