1. Faults such as unstable engine acceleration or weak acceleration and black smoke emissions
The high-pressure fuel injector in the high-pressure common rail system needs to accurately control the injection pressure, injection time and fuel injection volume, and the workmanship of the fuel injector is relatively fine. If there is a problem with the oil-water separator, the water and impurities in the diesel will have a negative impact on the fuel injection system. The plunger couple in the fuel injector wears and causes strain until the fuel injector gets stuck.
1.1. The engine emits black smoke
Damage to the fuel injector will cause unstable or weak engine acceleration, or cause black smoke and other malfunctions. In severe cases, it will directly damage the engine. Since the workmanship of the fuel injector is relatively fine, its price is also relatively high. Based on the above reasons, when there is a problem with the oil-water separator, it must be replaced in time.
2. Carbon deposits
If the oil-water separator is damaged, the water and impurities in the diesel will pass through the filter device and then accumulate in the intake valve, intake passage, and cylinder. Over time, hard carbon deposits will form, which will affect the operation of the engine. In severe cases, it will cause the engine to malfunction. destruction. Damage to the oil-water separator will cause valve carbon deposits, and valve carbon deposits will cause difficulty in starting the engine, unstable idling, poor acceleration, backfire during emergency refueling, excessive exhaust gas, increased fuel consumption and other abnormal phenomena. In severe cases, it may cause engine damage.
3. The engine emits white smoke
A damaged oil-water separator will cause the engine to emit white smoke, because the moisture in the fuel will turn into water vapor when burned, resulting in white smoke. The water vapor in the white smoke will damage the high-pressure fuel injector, causing insufficient engine power, causing sudden stops, and in serious cases, directly damaging the engine.
