Hello All,
No need to share views on the value of an accumulator, this post is for those who desire to operate one.
In the pursuit to make an automotive oil accumulator safer (they are not safe out of the box) I have made an interesting discovery.
My previous method of operation was to pressurize the oil gallery prior to start then re-pressurize the accumulator shortly thereafter.
One of my safety mods was to eliminate the air pressure gauge and its tiny tiny leaks, and install a oil pressure transducer feeding a signal to the engine monitoring system. This allows for me to track pressure rise as the engine compartment heats up. (which it turns out is rather nominal)
What I discovered is that the oil lines prior to the oil regulator get some serious pressure while the oil is cold. Between 120-140 psi has been seen with moderate temperatures outside. (60 degrees F)
So while my engine oil pressure was 60 ish that is not what I was charging my accumulator with. Now I am able to monitor recharge and stop at the pressure desired which for me is 55 psi.
If there is any interest in the other safety features I am glad to share.
