Why do we find every parking time, the exhaust pipe on the ground will have a pool of water, it is because the generated carbon dioxide and water, complete combustion of gasoline, water into steam at high temperature, but at temperatures below 100 degrees when the water vapor will condense into water, the ambient temperature is low, the exhaust white smoke is steam; if water droplets condensed water gathered becomes.

An exhaust pipe dripping is normal. Indicating that the engine is working properly. Full combustion and atomization effect is very good, generally seen in winter fog proof behind the exhaust pipe of the engine to exclude the state is very good.

It does not drip is not there a problem? First, the exhaust pipe dripping three conditions be met.

1, to correct the mixing ratio of oil, the oil supply system is normal, the fuel consumption in the normal range.

2, the engine cylinder pressure is normal, not damaged interior of the cylinder. Cylinder, Hey seals are a problem, if the internal engine wear occurs will lead cylinder pressure becomes low, the end result is incomplete combustion, that water come from?

3, the exhaust temperature is normal, the engine burst out of the heat in the cylinder, only a small amount of heat pump inside photographed, this indicating that the engine power output stable, if the exhaust pipe temperature is too high, the water vapor is unable to form droplets. However, too much water in the exhaust pipe is not good damage the oxygen sensor in the three-way catalyst, the oxygen sensor is primarily used to monitor the oxygen content in the exhaust gas, is formed an electric signal, determines ECY empty return electrical signal according to the oxygen sensor size fuel ratio, the fuel injection amount adjustment, to optimize engine state.

Below each row of tubes will have a small opening, and the main purpose is to prevent drainage when wading problem can not flow properly because of the angle. If someday rusted exhaust pipe, it is because the water a long time, small mouth causing congestion.
