Exhaust Smoke Indicator, What does it mean?
JAKARTA, DECEMBER 2024, Daihatsu friends must understand about exhaust smoke. White smoke coming from the exhaust pipe of gasoline-powered cars can sometimes confuse the layman.
Is this a sign that the engine is in very good condition, or conversely, is there a problem with the components in the 4-stroke engine? Especially if the white smoke appears only when the engine is first started or even continuously.
Indeed, some mechanics explain that the appearance of white smoke from the exhaust can be a good or bad sign. This can be seen from the condition of the Daihatsu car when it is started. Here is a detailed explanation.

Morning White Smoke Sign of Condensation Process
A gasoline car emitting thin white smoke in the morning can be considered normal in some situations. This is usually caused by the condensation process in the exhaust.
Quoted from smartdriving.id, condensation in the morning or cold temperatures causes water vapor in the air to condense in the cold exhaust. When the engine is started, the exhaust temperature rises and the water vapor will evaporate. This water vapor is what causes the thin white smoke to come out.
This phenomenon is very normal. Because the thin white smoke will disappear after the engine heats up, or after the car engine reaches normal operating temperature. Therefore, there is no need to worry as it is just residual dew that evaporates.
Continuous White Smoke Sign of Damage
Conversely, if white smoke continues to come out even though the engine has reached the ideal temperature. Moreover, the thickness of the smoke increases as the engine RPM rises. There may be a problem with the car, such as oil leaks or coolant entering the combustion chamber.
Even damage to the valve seals, cylinder head gasket, or cracks in the engine block can also be sources of problems. As a result, both oil and coolant that are burned together with the fuel gas will produce white smoke as a result of the combustion process.
Now, if white smoke continues to come out accompanied by a strange smell, engine knocking, or radiator water quickly decreasing. Immediately check at the nearest official Daihatsu workshop.
