Well that 125% could be part of the problem. That's a lot. 5% of that as fuel is a significant amount of extra fuel in the chamber, especially considering that fuel is all there ready to go boom when the diesel gets injected (which is a huge fire starter compared to a normal spark plug). Now as for...

In a gasoline engine water flow is supposed to be in proportion to fuel flow. Usually 25% or so is when the magic truly starts. Although that's probably too much for a diesel, you'd probably be served by using a load input for your system that scales as least partially with fuel. Boost is not a goo...

Thanks, but it's a Renault / Dacia K9K 898 motor, which is also used in Nissan, Merc and Volvo.

Luckily, it has Nikasil coated cylinder walls and piston rings and uses semi-synthetic oil.

More information please: Certainly - 89 cid is 1.458 litres – yes, 1.461 litres actually, 89 was rounded The 1.5 GPH is 94.64 ml/min flow rate currently. - how many cylinders - 4 - bore/stroke - 76 x 80.5mm - 2 or 4 valve per cylinder - 2 - OHC or cam in block - OHC - direct or indirect injection -...

Copying the following paragraph from this link https://s0.whitepages.com.au/0c6653ac-4571-418f-8d64-f0cbd8d95459/engine-australia-document.pdf and adding further description in parenthesis ... The injected liquid fuel droplets must reach distillation temperature and vaporise before ignition occurs....

This is because the combination of the large heat capacity of water and large heat of vaporization of methanol gives the mixture the benefit of each. Got it - thanks Is my set-up injecting too much? I'm potentially injecting 1.5 gallons per hour in an 89 CID motor. As at my maximum boost I should b...

The large heat absorption in evaporating the methanol is lowering the temperature at the end of the compression stroke where high temperature is necessary for diesel ignition. Diesel ignition is enhanced by higher temperature intake air and higher temperature at end of compression stroke and time o...

20% unburnt diesel seems like an incorrect figure for a cruise situation. How did you arrive at that figure? And also did you actually mean 5%? That also seems like an unusually low amount for symptoms to appear at given that LPG gets used as a substitute/power adder in diesels all the time and you...

At what point you start adding it ? WM is used to cool exhaust temp when it gets too high , nothing else. Straight water is better if freezing is not a problem. My settings are: 7 psi for minimum (start) and 50 psi for maximum Seven is one psi above my normal cruising boost pressure. My scan tool s...

Has anyone dialled in water-meth-injection (WMI) in a diesel motor?

I don't get any quench at 100% water, but if I add any alcohol at more than 5%, I start getting bucking (not running smoothly, diesel knock). If I increase the alcohol any more, I start getting blue-white smoke.

Still lots of investment decisions ahead for 45 year olds.

I wonder if private equity has longer time lines.

I'd have a problem being the CEO of a listed company due to the short attention span of bourse shareholders. Decisions about capital projects would be skewed.

Is that a sustainable business model - manufacturing inferior parts? Short-term gain - sure, but long-term?

Caveat: I believe in serendipity. I had just finished wrapping another exhaust section and had some exhaust wrap left over. So, I got about four wraps around this tinkling section in its mid-section. For the first in a long time, encouragingly, I heard the engine over the exhaust during a short run....
