White smoke during start-up

[barako ba ma]

Correction lang po for everyone's knowledge on smoky exhaust. From the book
AUTOMOTIVE TUNEUP by William Crouse & Donald L. Anglin, chapter 34 page 365 ang reference.

SMOKEY EXHAUST : 1. Blue smoke - Excessive Oil Consumption
2. Black smoke - Excessively rich mixture. Meaning
more fuel.
3. White smoke - Steam in exhaust. Meaning there's
water.

hehehe please read the disclaimers on textbooks written by william h crouse and donald l anglin, books written by jack erjavec, by john remling. the texbooks, sorry to say have disclaimers and are broad, generalized and basic in coverage. if a diesel engine were burning oil it might show minimal bluish white smoke until the engine warms up to normal operating temperature.
3. White smoke-Steam in exhaust. meaning there's water; the by products of an efficiently burning engine are H2O and CO2. fuel (HC) combined with O2 typically yields H2O and CO2 and maybe if the combustion temperature exceeds 2500 degrees fahrenheit, will yield some NOx
