Garbage truck: Causes & solutions to black smoke from engine
When the garbage truck engine is working normally, the smoke emitted from the exhaust pipe should be colorless and transparent gas; but sometimes black smoke from the exhaust pipe occurs. It is important to know that the black smoke from the exhaust pipe not only affects the power of the vehicle , Economical, it will also seriously pollute the atmosphere, affect air quality, and affect people's health. Therefore, we need to understand the reasons for the smoke from the garbage truck engine and solve them according to the reasons. The following are the reasons for the black smoke and the elimination methods:
The black smoke from the engine of a garbage truck is due to frequent changes in working conditions and environmental conditions with the vehicle conditions, resulting in changes in the color of the smoke, so the smoke color will also change when the engine fails. The exhaust pipe emits black smoke, indicating that the mixture is too rich and the combustion is incomplete. Usually the following conditions can cause this to happen:
1. The fuel supply time is too late;
2. Excessive fuel supply or poor fuel atomization;
3. The engine is overloaded;
4. The air filter or intake pipe is blocked;
5. Insufficient cylinder pressure.
If black smoke occurs, the above conditions need to be eliminated as follows:
1. Check whether the choke door is fully opened in time, and perform high-speed maintenance if necessary;
2. After the flame is turned off, look at the main nozzle from the carburetor port. If oil is injected or dripped, the oil level in the float chamber is too high. Adjust to the specified range and tighten or replace the main measuring hole;
3. Check whether the air filter is blocked, and the air filter should be cleaned, dredged or replaced frequently.
Of course, the engine emits black smoke. In addition to the above factors, there are other factors, such as poor oil return in the turbocharger oil return pipe, failure of the brake system sensor and other factors, which can also cause the engine to emit black smoke.

Otherwise, it will not only replace a certain part of the engine, but also may cause the engine to be overhauled. Therefore, drivers and friends must pay attention to the problem of black smoke from the engine. In the selection of engine oil, you must choose genuine engine oil, so as to reduce the phenomenon of black smoke.
