Analysis of Causes of Garbage Engine Black Smoke: Under normal circumstances, when the garbage truck engine is working, the fumes emitted from the exhaust pipe should be colorless and transparent gases. However, sometimes Hu appears to have black smoke in the exhaust pipe; usually this condition is due to the frequent changes in working conditions and environmental conditions with the vehicle conditions, resulting in changes in smoke color, so the engine will fail smoke color will follow change. Exhaust pipe black smoke, indicating that the mixture is too concentrated and incomplete combustion. Usually the following conditions will cause this to happen: 1, too late for oil; 2, excessive oil supply or poor atomization of fuel injection; 3, the engine is overloaded. 5, cylinder pressure is insufficient; 6, too late to supply oil; 6, excessive fuel supply or poor atomization of fuel injection; 7. The engine is overloaded. If black smoke occurs, you need to do the following to eliminate the above conditions: 1. Check whether the choke valve is fully opened, and if necessary, perform high-speed maintenance; 2, after the flameout from the carburetor mouth to see the main nozzle, if there is oil injection or drip, then the oil in the float chamber is too high, should be adjusted to the prescribed range, tighten or replace the main amount of hole; 3, check the air filter is blocked, the air filter should be often cleaned, dredged or replaced. Of course, the engine black smoke, in addition to the above factors, there are other factors, such as supercharger oil return pipe poor, brake system failure sensor failure and other factors, can also cause the engine black smoke phenomenon. In addition, Xiao Bian recommended the majority of owners, we must choose a quality, quality guaranteed oil, to ensure the safety of the car.

1. Description
In the drilling process, the drill bit is the main tool to break the rock and the wellbore is formed by the drill bit breaking the rock. How well a wellbore is formed and the length of time it takes are not only related to the characteristics of the rock in the drilled formation and the performance of the drill bit itself, but also to the degree of mutual matching between the drill bit and the formation. Reasonable selection of drill bits plays an important role in increasing the drilling speed and reducing the overall cost of drilling.
The drill bit is one of the important tools for oil drilling work. Whether the drill bit adapts to the rock properties and its quality plays a very important role in the selection of drilling technology, especially in terms of drilling quality, drilling speed and drilling cost.
2. Specifications we can offer
At present, there are many types of drill bits used in the petroleum industry and mining industry. The drill bits are classified according to different drilling methods. They can be divided into PDC drill bits, roller cone bits, scraper bits and mining diamond coring bits. These drill bits are the most basic drill bits and we all can provide.
