Most motorists only know how to drive and use cars, but they don’t know how to taste and maintain cars. Observing Tanyue’s exhaust emissions is a big question! What is the reason for dripping water in the exhaust pipe? In winter, dripping or white smoke from the exhaust pipe is more obvious because the temperature is lower and the temperature difference is large. In winter in some northern areas, there is even ice at the exhaust pipes. Let’s take a look with me to see what the reason is.
If these three points are met, the exhaust pipe will drip, which is normal.
1. The mixture ratio of gasoline and air is correct, which means that the car’s fuel supply system is in normal condition.
2. The engine cylinder pressure is normal, there are no wear or component problems inside the engine cylinder block, and the gasoline is completely burned.
3. The temperature of the exhaust pipe is low. If the temperature of the exhaust pipe is too high, water vapor cannot form water droplets.
When these three conditions are met, the exhaust pipe will drip. So dripping water from the exhaust pipe proves that the vehicle is in good condition.
Tanyue’s exhaust pipe is hidden under the car body. We saw that this is a decorative fake exhaust pipe.
Real exhaust emissions do drop water into the ground through the exhaust pipe.
Here, if the exhaust pipe removes strong white smoke, it may be that the fuel is impure and more water vapor is mixed, or the air filter is blocked, resulting in insufficient intake air, and the coolant enters the cylinder. If the exhaust pipe removes black smoke, it is generally because the engine contains a lot of mixed gases when doing work, and the gasoline is not burned sufficiently. Specifically, it may be caused by blocked engine air filter, poor spark plug, air leakage in the intake system, and fuel injection nozzle. Due to reasons such as poor atomization status, professional inspection is required.
Impure fuel can also lead to carbon deposition in the engine, which will be very harmful to the vehicle.
If you have too much carbon deposition, you will first feel that your car is speeding up, lacking power when overtaking, and getting bored. The engine will shake with a muffled sound when driving, which is a manifestation of poor fuel supply; then fuel consumption will increase, which is also a problem that many drivers are worried about; more serious carbon deposition will lead to poor ignition or difficulty in starting, and excessive carbon deposition on the spark plug will cause.
Too much carbon deposition leads to weak speed increase and muffled noises.
Many motorists ‘clubs say that the problem of running at high speeds can be solved. Running at high speeds can only remove part of the carbon deposits that have not yet been solidified, and those solidified carbon deposits cannot be removed at all.
Too much carbon deposition will increase fuel consumption.
There is a feeling of frustration when changing gears, which proves that the oil circuit is not smooth.
So how to prevent and clean up carbon deposits? In fact, as long as it is a fuel-fueled vehicle, carbon deposits cannot be avoided. Therefore, the prevention of carbon deposits is very important.
1. When carbon deposition is serious, it is recommended to go to a 4S shop for professional carbon deposition cleaning and washing
2. Go to a regular gas station to refuel. The inferior fuel used in informal gas stations may contain a large amount of impurities, which will cause insufficient combustion and cause carbon deposits.
To develop good driving habits, you usually need to replace the spark plug within 20,000 – 30,000 kilometers. At the same time, you should always pay attention to the daily performance of the vehicle. When using additives, you should add them according to the tips of your own car maintenance manual.
It is necessary to replace the spark plug, and it will also avoid carbon deposition.
Finally, it is necessary to develop a good driving habit. Driving at idle speeds, driving in low gears, stepping on the brake and accelerator violently, etc. will cause insufficient burning of gasoline and thus deal with carbon deposits.
