Exhaust valve opening and exhaust valve closing

[Blueprint]

Need to get this straight.

Example:

If I am closing the exhaust valve at let's say 8 degrees as an example for a reference point.


By going to an exhaust event of 13 degrees (later closing). I would be retarding the opening of the valve, which causes the later exhaust valve closing.

Correct?


Which also means by going to a closing event of 5 degrees. I have now advanced the opening and closing, when compared to the previous 8 degrees I started with. Which would equal and exhaust valve that now opens 3 degrees earlier but also closes 3 degrees sooner.


Essentially, all numbers after 8 would retard the opening and closing, all numbers before 8 would advance the opening and closing. That is all based off 8 degrees as my starting point.

Correct.

Event Advanced is earlier in the engines rotation. Event Retard is later in the rotation.

You get a pay advance you get money earlier. Your boss is a.... NVM.

Appreciate the help!

Sometimes I drive myself crazy looking at logs, then thinking of theory's applied to certain setups, etc
