The main function of the oil-water separator of the truck is to filter the water in the fuel. After long-term use, the water separated from the fuel will accumulate into the water cup of the oil-water separator. When the water content of the water cup reaches the alarm line of the water level sensor, the vehicle will appear fuel water alarm.
The filter element in the fuel filtration system, in addition to filtering the mechanical impurities in diesel, has an important function is to filter water. The existence of water in diesel is very harmful to the engine: rust fuel system components, scale blocking the oil circuit, affecting the engine power output, and even damage the entire fuel system. Oil-water separator is a part of the fuel filtration system, the main function is to remove the water in diesel, reduce the failure rate of the fuel system, and extend the service life of the engine.
The principle of truck oil-water separator is mainly based on the density difference between water and fuel, the use of gravity sedimentation principle to remove impurities and water, and the interior of the separator has separation components such as diffusion cone and filter screen. The oil-water separator has other functions, such as pre-heating the fuel to prevent wax formation, filtering impurities and so on. Drain the water valve in the sedimentation chamber at the lower part of the oil-water separator, and open the valve when the water accumulates to a certain amount.
Because the high pressure injection nozzle needs to accurately control the injection pressure, injection time and injection amount, if there is water or impurities in the diesel oil is not filtered clean, it will cause wear and tear to the plunger couple in the fuel high pressure pump and the injection nozzle until the injector is stuck. The damage of the injector will cause the engine to accelerate unstable or weak, or emit black smoke and other faults, affecting the normal operation of the vehicle.
As the first stage of the multistage filter system, the oil-water separator has the function of filtering large particles of impurities and water. As early as the implementation of the national three emission standards, the requirements for fuel pressure, the water separation efficiency of the filter has been required to reach 95%, if you can not achieve such a filtration effect, a long time will cause damage to the fuel system.
The choice of the oil water separator of the truck is the same, if the fuel supply system of the diesel engine does not pay attention to maintenance, the quality of the selected filter is not up to standard, and the fuel carries impurities into the engine, which may lead to poor oil supply or the engine cannot start normally over a long time, and the symptoms such as power decline, fuel consumption increase, and black smoke. The selection of high-quality filter element and regular maintenance can effectively reduce the incidence of failure and extend the service life of the engine.
If the fuel water alarm is not eliminated for a long time, it will cause other fault codes, and even cause vehicle torque limit, affecting normal driving. Therefore, it is necessary to discharge water regularly to the oil-water separator, and the recommended frequency is once every half month or once a month.
In daily driving, truck friends have more or less encountered the problem of starting difficulties, there are many reasons for starting difficulties, low pressure pipeline gas is one of the main reasons. For the difficulty of starting non-leakage intake, the gas needs to be removed from the system, and the oil-water separator can play the role of pumping oil exhaust.
