car running cooler after cetane addatives?

[kevinm]

Does this stuff make the engine run that much more efficiently or has my gauge just started to read 1/8 less than usual on the same hill i pull every day. I added double the recommended as im trying to get rid of black smoke, which it definitely helped.

ive never noticed the gauge reading lower from adding something to the fuel..

[kevinm]

i think your right. but i have almost zero smoke now. it must have just been a cooler day.

If it turns out to not be a fluke of temperature, I'd suggest checking your injection timing. Boosting cetane shortens ignition delay, which has a similar effect as advancing the timing. Maybe you could use a little more advance.

Check your internal pressure.

I definitely notice a smoother tone, less smoke and less power on B100.

is that for smoother tone mean retard?

When I add wax to the diesel it gets smoother and quieter.  When I run BioDiesel I get a few more lbs of pressure in the pump.  When I run WVO I get a lot more pressure in the pump and that is with the oil heated to 160 F through two different heaters.

So I get a lot of different advances depending on the fuel type.  I was intreged by the questions of changing the timing on the fly as it "may affect" overall economy for some.  As of yet I haven't figured how to change timing under power at 65 mph.  Sitting behind the wheel for as many hours as I do I haven't been enlightened enough to try something just to see if it works.  I think the key is being able to see the advance under loaded conditions.  Then change the timing accordingly.

I`ll try that with ball valve,I just HAVE to,but now my engine is so OK and winter is coming,and of corse I must by valve,as I write on FAQ maybe on spring.Best in your WVO.

how are you going to adjust internal pump pressure with a ball valve?

the REGULATOR is the part of the pump that determines the internal pressure..

how are you goin to change the pressure with a ball valve? making a bleed of sorts?

[ORCoaster]

Yeah,  How are you doing this?  The change needs to be made at the PR to make a difference in the internal pump pressure.  That is my problem, how to vary the PR setting when switching to different fuels and monitoring the internal pump gauge inside the car to keep it the same. 

Maybe he intends to starve the inlet to control the pressure.  I experienced that problem and it controls the IP pressure to a lower end.  So I suppose you could in theory set the PR to be high and then back off from that by restricting flow on the inlet.  But I don't think simply cutting back volume with a ball valve will do it.  Maybe it will.  I was experiencing vacuum pull as the flow restrictor. 

A dirty filter = ball valve in function.  Let him try it and see.

starving the inlet does not allow te advance mechanism to operate properly tho..

and that came straight from Giles.. so i would not try to restrict the inlet, or the outlet for that matter..

the idea i had, was to JACK the pressure regulator WAY UP, and use the ball valve to be a variable size OUT bolt..

i dont think it works like that buddy..

[R.O.R-2.0]

Go ahead, try it tho.. i would LOVE to see you prove me wrong!

[ORCoaster]

Oh yeah, brain kicked in here.  Starving the inlet to reduce pressure does happen but then the amount of fuel is also reduced so guess what happens?  Stall or very slow mph. 

Not sure what you would be controlling with the ball valve even if the pressure was up.  Isn't the high pressure passed internally to the advance mechanism then to the overall pump body?  It has already advanced the timing before you get a read on it. 

Yeah, prove us wrong, we'd love it.
