Carbon Monoxide Poisoning


Diesel Exhaust Gases:


Factors tending to increase CO:

  • Abrupt change in power setting / load changes
  • Less than ideal injection timing, fuel aerosolization, distribution, and combustion chamber shape
  • Low combustion temperature
  • Low operating rpm
  • Large, heavy-duty size as compared to light-duty engines
  • Engine not properly maintained
  • Blocked air intake



    Concentrations of 1,000 - 5,000 ppm CO in undiluted diesel exhaust gases are common, and levels up to 60,000 ppm or higher, are possible.
