3 grey smoke emissions and the reasons for the exclusion method

Engine exhaust from the gray, some of the fuel for low-temperature, gas atomization bad, there was no time to burn fuel from the exhaust pipe in the discharge. The reasons for this phenomenon are:

(1) injection late and injector leakage when fuel injection, injection pressure is too low, fogging performing well, the low-temperature combustion, and there was not enough time to form white smoke to be discharged. Approach, the correction injection time to check the status of the injector.

(2) a low pressure within the cylinder. The cylinder, piston ring wear components, as well as bad valve seal caused the engine running when in the recently launched grey smoke, and then with the rise of temperature, smoke or into desalination smoke. Approach is the replacement of the cylinder liner wear, the piston ring or repaired valve, valve seat ring.

(3) diesel fuel in the water. If the engine after launch out gray smoke, along with machine-rise, gray smoke still exist, and will very likely be a diesel mixed with too much water. Solution is to boot a day before the fuel tank drainage valve will be open, bottom sediments and water emissions swap.

To sum up, the engine exhaust anomaly is a comprehensive reflection of the internal fault. Therefore, the exhaust is not normal working conditions good or bad judgement engine one of the important symbols, if timely treatment can guarantee that the ideal use of diesel engines, to avoid unnecessary economic losses.
