The engine is like the heart of a diesel generator set. The air filter is a key component to ensure the normal operation of the generator set. It is responsible for filtering the dust and moisture in the air and providing clean air for the generator set. There are many types of air filters on the market, and inferior products are also flooded with them. Once used, they can easily damage the generator. Moreover, the current generator components are very expensive, and the cost of repairing once is very high. Using inferior air filters can save about 100 yuan per 100 hours on average, but the cost of repairing the generator set is far more than 100 yuan.
The fatal cause of generator damage: The service life of generator is directly related to the speed at which the generator sucks in pollutants. Only 100 to 200 grams of dust is enough to destroy a diesel generator. The air filter on the generator protects it from The only way that pollutants in the air affect.
The first level of air entering the engine through the air filter is the turbocharger. After the compressed air enters the intercooler, it flows through the intake pipe (some engines are equipped with an intake preheating system) and then presses into it. The intake manifold is finally pressed into the cylinder by the manifold and mixed with diesel for combustion.
In fact, the filtration accuracy is not the only criterion for judging the quality of the filter element. The air intake resistance is a rigid indicator of the quality of the filter element.
So, if the air filter element's filtration accuracy is insufficient or the air intake resistance is not up to standard, what harm will be caused?
1. The intake resistance increases and the combustion efficiency decreases. Poor air filter will lead to excessive air inlet resistance, and insufficient air inlet will lead to low combustion efficiency of the generator. The generator is likely to have insufficient power. Due to insufficient fuel combustion, the carbon deposit will cause serious damage to the internal parts of the cylinder such as fuel injector, cylinder head valve and so on.
2. The intercooler is blocked, and the ventilation rate becomes poor. Dust and debris from poor-quality air leakage can easily block the intercooler, causing a decrease in ventilation and insufficient heat dissipation performance. The fault of intercooler blockage is not easy to be found under normal circumstances, and it often causes users to go to the doctor indiscriminately, causing unnecessary losses.
3. The dust filter is not clean, and the parts are severely worn. Once the dust enters the generator, it will cause serious wear of the valve sealing surface, cylinder liner, piston, piston ring and other components, resulting in a decrease in the cylinder sealing performance, directly leading to insufficient compression ratio and gas leakage. At this time, our trucks will show the phenomenon of insufficient power, high fuel consumption, large downward exhaust, and difficulty in starting.
4.The quality of the filter is poor, and the adhesive falls off. If the filter is broken, not only will the filtering accuracy become lower, the iron filings that fall off may be sucked into the turbocharger, or will cause fatal damage to the blades.
5.Exacerbate engine wear. Dust sucked into the air intake system will aggravate the wear of the cylinder block, pistons, piston rings and other components, resulting in reduced engine combustion efficiency and attenuation of service life. At the same time, this is also the cause of symptoms such as higher engine fuel consumption, weaker power, and difficulty in starting.
In fact, the seemingly insignificant air filter element is very important. You must polish your eyes when purchasing. It is recommended to choose Cummins air filter. The filtration efficiency of our filter paper is about 99.99%. You must not choose low-quality air filter for a moment, otherwise the saved price difference will definitely outweigh your losses.
