In the process of use, Excavator engine will produce carbon deposition, then what are the carbon deposition and the hazards?
1. Rise in Carbon disposition, fuel oil is not pure
In fact, it is impossible to achieve 100% purity, the filter will have a filter limit, so some small impurities remain in the fuel after carbonization deposition in the cylinder.
2. Intake is not pure
Two filter (coarse filter, fine filter) can not guarantee 100% filter out the air in the dross. These tiny dusts enter the combustion chamber with the gas, which is deposited in the cylinder after being carbonized by combustion.
3. Sports parts wear
Cylinders, cylinders, valves, pistons, pistons, etc. in the process of high-speed movement will produce wear debris, the debris through the heat will be deposited in the cylinder.

The danger of carbon deposition
Said the carbon hazards, first of all to know the deposition of carbon deposition. After the combustion of carbon deposition, after the explosion of shock, and ultimately will be deposited to the piston ring groove, injector fuel injection port, valve Department.
 
  1. Deposited in the piston ring groove
Combustion of carbonated deposits accumulated in the piston ring groove, will accumulate more, stick the piston ring, and ultimately the piston ring deformation, highlight, scratch cylinder liner, resulting in cylinder, biting cylinder. Causing the cylinder piston piston ring all scrapped.
2. Deposition on the injector injector
The end result is to plug the fuel injection port, and now the basic technology can not repair the EFI fuel injection port, can only replace the injector.
3. Deposited at the valve
The accumulation of more will cause the valve force uneven, valve stem break, the valve chassis broken situation. The result will cause the valve, lock, seat, piston, all damaged.
Through the above can be learned  that the engine carbon deposition can cause very serious consequences, so be careful to understand the situation of the machine, especially the year long, the number of hours of the machine. Concerned about whether the momentum is stable, there is no decline. Once a problem occurs, to timely repair and find another replacement.
