Causes of blocked oil circuits in automobiles:
Poor engine cooling system is the basic reason why the engine temperature is too high and the engine stalls due to "blockage of air".
According to the design and use requirements of the car, special coolant should be added to the car's cooling system and replaced every two years. The special coolant has the advantages of protecting the radiator, water pump and engine cylinder block from corrosion and having good heat dissipation effect. However, some users do not maintain their vehicle as required and use tap water or unspecified coolant to add it to the radiator. Since this water contains minerals, it is easy to form scale in the radiator and engine water jacket during use, as well as tartre. has thermal insulation properties, preventing the radiator and cylinder block from dissipating heat over time. Additionally, minerals in the water will undergo electrochemical reactions at high temperatures, causing corrosion of the engine's radiator, water pump, and cylinder block. Corrosion and scale can easily cause the radiator cooling hose to become blocked, causing the radiator and cylinder block to cool. Engine. The function is significantly reduced, resulting in the engine compartment temperature being too high and the “airlock” failing.
For vehicles with "air lock", the following measures can be taken: remove the air filter connection pipe above the carburetor, spray the inside of the carburetor with carburetor cleaner, and at the same time start the Engine and maintain the speed at 2000 rpm. Once the engine is running smoothlyIf stable, release the accelerator pedal if the speed is below 1000 rpm, adjust the carburetor and increase the speed. Use a special cleaning agent for aluminum radiators to clean the engine. the entire cooling system. Clean the system. Add special coolant to the cooling system and keep the fluid level at the upper limit. Clean and adjust the carburetor. Maintain engine idle speed at 850 rpm when the air conditioner is not operating and 1000 rpm. min when the air conditioner is working. If the vehicle condition is not good, the idle speed can be increased appropriately to ensure the fuel supply capacity of the fuel pump. Check the condition of the spark plug. There should be no carbon deposits on the spark plug. electrodes. The normal color is gray white or light red.
And the water tank of a generatordiesel Come release the water. Generator manufacturers believe that because the external ambient temperature is too low, the cooling water should be discharged after 15 minutes of shutdown when the water temperature has dropped, not immediately, otherwise the temperature difference between the fuselage and the external environment will be too important. , causing the diesel generator to fail. Some parts of the unit are deformed, which in turn affects the performance of the diesel engine (such as cylinder head deformation, etc.). When the cooling water stops flowing, it is best to shake the diesel generator several times. At that time, the remaining cooling water that does not flow easily will flow out due to the vibration of the diesel engine. can prevent the water on the cylinder head from freezing. If it falls, cooling water will flow into the engine oil pan. The operator should also note that if the vacuum switchwater switch is not removed, the water drain switch must be in the open state after water draining is completed to prevent the remaining cooling water from temporarily draining out for various reasons and it freezes. the corresponding parts of the diesel engine. Generator manufacturers remind users not to activate the water release switch and everything will be fine when releasing the water. They also need to pay attention to the specific water flow conditions to see if the water flow is steady and whether it is getting smaller. or faster and slower. If these occur, this indicates that the cooling water contains impurities that hinder the normal flow of water. At this point, it is best to remove the water drain switch and let the cooling water flow directly from the body. If the water flow is still not smooth, use hard and thin steel objectssuch as wire to dredge it until the water flow is steady.
