Gasoline generator filter replacement method:
The method of replacing the air filter of the generator is very simple. Some generators have filter clamps and some have a plastic screw at the bottom. To replace, unscrew the screw or clamp to see the filter.
Then a small piece of iron that is responsible for holding the filter is removed from the filter and the filter should be left in this part. The filter should never be washed, but only with the wind or in the absence of facilities, clean the filter with gentle blows.
To completely change the ventilator, the same steps must be done, then unscrew the 2 screws inside the ventilator and open another screw located behind the ventilator. At this time you can release the filter and close the replaced filter.
How to start and service a generator
To start, you must first pour the fuel into the tank and pour the oil into the oil "gauge" chamber. Care must be taken to do this so that the lowest thread is poured into the oil gauge.
The fuel valve of the tank should be opened and the throttle should be pulled out, then the device should be turned on. The button is on. Make sure that the start time is not under load.
After turning on the device, return the throttle to its original position and you have to wait a few minutes for the engine to warm up, and after the engine warms up, start loading the device.
To turn off the device, you must first take the engine out from under the load to cool the engine slowly, after a few minutes, turn the OFF / ON button to OFF, and finally after turning off, you must close the fuel valve.
A few important points
The standard conditions for using gasoline devices are 5 hours of operation and 2 hours of rest. In 4-stroke gasoline engines, the oil of the device must be changed every 50 hours.
To change the oil, 40 automatic oils are used. It should be noted that in devices that have oil filters, after changing the oil three times, the oil filter must also be changed.
Make sure that the oil and gasoline inside the machine and the gasoline inside the carburetor are empty when the machine is not working for a long time.
Types of filters and their function
All tools equipped with internal combustion engines need air and oil filters, and in various types of diesel burners, diesel filters should be added to this group. Of course, in previous years, with the increase of air pollution in cities, new cars have been equipped with special air conditioning filters inside the cabin.
Although each type of filter has its own specifications, in general it should be able to separate particles of 5 microns or larger and have the necessary resistance to the flow of refined materials and optimal efficiency in its expected useful life.
In addition, other features such as high heat resistance, constant filter size, insensitivity to air changes and humidity, ease of use are the characteristics of a good filter.
1. Air filters
The filter set with the chamber and its attachments are known as fans, which are made according to different climatic conditions and technical specifications of the engines, different fans to supply the air they need. Some of the different types of fans are wet, oily, dry and cyclonic.
In terms of pollution, air is divided into low-dust, medium-dust and high-dust environments. An oily combination is used with cyclones or pico cyclone aerators.
In wet fans, the air purifier and the filter chamber are mixed with oil, and their oil can be fixed or interchangeable, which in the second type, washes the filter and is almost non-existent today.
These fans are very diverse and depending on the expected technical conditions, the filter is made of plant fibers, sponges, metal woven nets or non-woven fabric.
The filter element of dry fans is a paper made of special fibers in the form of pleats. The sucked air passes through the inner filter, which is protected by a metal mesh protector, leaving dust particles on the outer surface of the filter and between the filters, and the clean air is directed from inside the central vent pipe to the diesel engine.
Replacement of the filter should be done according to the recommendation of the engine manufacturer and after a certain distance, in the meantime, the condition of the environment in terms of dust, humidity, etc. should also be considered.
Of course, in heavy vehicles, warning signs such as colored tape, warning horn, etc. are generally provided for the driver to be aware that the air filter is dirty.
Although the safest way in passenger cars is to change the air filter,
If there is no access to the filter, the air filter can be cleaned in the following three ways:
1. Hit the filter head a few times.
2. Blowing compressed air with a maximum of 5 atmospheres of pressure from inside to outside the filter.
3- Wash the filter with mild water and some detergent until it does not foam (20 grams of detergent in 10 liters of water). The air filter should be dried after washing and the paper should be safe.
The smallest hole or tear in the air filter will make it useless.
In this regard, the ventilator of some cars has a long pipe that draws air from the roof of the room into the engine so that the least dust, especially heavy vehicles used in mines, enter the car's propulsion.
Of course, in truck and desert vehicles equipped with waterproof propulsion, with this method, water does not enter the engine when crossing rivers and ponds.
2. Oil filters
To prevent the flow of oil in the engine from decreasing or interrupting, even when the filter vents are blocked, a safety valve is located in the filter or its base, which opens as soon as a pressure difference occurs between the inlet and outlet flows of the filter.
In this case, the oil is refined in the form of a sub-stream and the refining process is gradually reduced. To increase the desired properties in the oil, special substances are added to it, especially detergents and suspenders, so that the pollutants remain in the form of fine particles floating in the oil instead of settling.
A standard filter that is made in accordance with the principles and quality materials, will not prevent the passage of additives and will not reduce the quality of the oil, and except for the acidity produced in the oil due to combustion, other materials and particles from combustion largely refines.
Studies show that a proper filter significantly reduces oil contamination and thus increases oil life. In this way, a good filter increases the useful life of the engine while maintaining the properties of the engine oil and delaying erosion.
3. Micro top filters
Micro tops in oil filters show their delicacy and precision in purifying very fine particles. These filters, which are used to purify oils, fuels and air, are disposable and the used filter should only be replaced with a new filter according to the recommendations of the engine manufacturer along with its base.
In general, micro top filters are designed and manufactured in various conditions for 10,000 kilometers or about 300 hours of car engine operation, but in any case, their useful life depends entirely on the size and method of operation of the car and its working environment.
Micro top filters are produced and supplied in paper types, fiber sets and replaceable screw filters and MICRO TOP is written on their packaging. Also, the price of these filters is more expensive than similar models.
4. Fuel filters such as diesel, gasoline, fuel oil
Fine micro top, felt, or tubular filters are generally used to purify diesel and other organic fuels.
In plate or tube felt filters, the purifier is in the form of several sheets of felt on top of each other or in the form of a tube of felt that performs the task of refining the fuel.
Contaminants in the fuel remain on the outer surface of the felt when passing through the filter and the fuel is directed to the injector pump. For today's advanced engine fueling systems, fuel cleanliness is of particular importance.
Because the least pollution causes disruption in the operation of injecting fuel into the cylinder. Therefore, microcap filters are used in light cars and a combination of a micro top paper filter and a felt filter are used in heavy vehicles and diesel engines.
A few important and key points
Due to the long life of new oils, it is recommended to change the oil and filter at the same time of each service, because otherwise, the used oil remaining in the filter will cause the new oil to become dirty and contaminated. It reduces its efficiency quickly.
By performing the purification operation, the filter holes are closed and the purification speed is slowed down.
If the dirty filter is not replaced within the specified time, the oil flow will not be sufficient, so the safety valve of the filter is opened and the lack of oil required by the engine is provided in an unrefined form, which in the long run, shortens the engine life. Will have.
It is always necessary to ensure the health of the washer after selecting the filter for each engine, it is necessary for the washer to be in the right place. Defective gaskets should be replaced immediately because a good gasket means less oil, keeps the engine healthy and reduces maintenance costs.
The final point is that each filter is composed of many components and only by having equipped laboratories and after careful examination, the quality of a filter can be determined and determined. Therefore, using known and standard filters is the easiest, and most reliable way to ensure the use of a high quality filter.
Troubleshooting and generator repair training
Here are some suggestions on how to look or get an appointment for antique items.
1- The engine does not start
- This problem may be due to the non-adjustment of the regulator. At this stage, the regulator should be checked and adjusted.
- Checked the injector power.
The interval between refueling and injector spraying may not be set correctly. The device must be adjusted according to the instructions. Another problem is that it may have clogged the needles.
They should be looked at and cleaned or replaced if they are clogged. Also check that the needles are tight inside the injector body.
- Existence of air in the fuel supply route and fuel tank, in which case ventilation should be done.
2 - A lot of noise coming out of the generator motor
- There may be a problem with the engine load. If the engine load is more than the power; Or if the load on the cylinders is unevenly distributed, the device must be controlled and the engine must be adjusted.
Pistons and valves should not be loose or tight. If they need to be replaced, they must be replaced to repair the power generator.
- The generator motor should not be too hot. Overheating can be caused by a fault in the thermostat, a lack of coolant, and air inlet and outlet systems to the engine and radiator.
3. Smoke coming out of the generator is not normal in color
- If the smoke coming out of the generator is blue, the problem is due to the large size of the oil or the wear of the oil rims.
-If the exhaust fumes are gray, the injector should be inspected for contamination.
It is also necessary to check the size of the load and adjust it if necessary to repair the generator.
- The smoke coming out of the generator may be black. In this case, to repair the power generator, the inlet air filter must be checked and replaced. Look for injector needles that are not clogged.
Another reason could be related to fuel. If the generator fuel is not of good quality or there are impurities in it, black smoke may be emitted.
