Diesel Engine Exhaust Gases

[Marsupial]

What many are missing is not what is in exhaust gas but whats NOT in it - oxygen! its a lack of breathable air that will kill you.

Some interesting reading:

CO poisoning on Targa 28 (petrol engines / diesel heater)

Carbon Monoxide Advice (don't be put off by it being of US origin).

From which, I have taken the following (note the bit in bold which was something I didn't previously know - although the CO in diesel exhast is << that in petrol):



CO alarm sounds like a good idea, but plenty of other stuff to get right first.


Edit to add: That second link also includes tests of CO exposure when wake surfing (OK) and "teak surfing"(not OK) behind a petrol boat (I'd never heard of "teak surfing" - it's body dragging off the bathing platform...)

The numbers you gave is quite hi! A normal otto engine ops! you are right!
6% CO is optimum for a lambda one engine at full load! 60 000ppm!

Im glad im working with big engines! I have seen up to 1000ppm on diesel

Normal is much lower! At full load far below 100ppm!

Think I made a measurement on my old diesel BMW ideling. CO and HC 2-400ppm? 2.5 prechamber diesel! Long time ago!
