2. When the engine idle speed is unstable, adjust the idle speed first.If the fault persists after the idling speed adjustment, check whether the idle speed measurement hole and the idle air volume hole are blocked. If the measuring hole is blocked, clean it with gasoline or acetone and blow it through with compressed air. If necessary, it should be overhauled and adjusted.
3. At this time, please check the nearby pipes first to see if there is breathing. If you inhale, it is equivalent to air leakage. There is too much carbon accumulation in the throttle valve and the surrounding intake duct, the cross-sectional area of the air channel changes, the adjustment unit may not be able to accurately adjust the idle intake, the mixture is too thick or too thin, and the idling speed of the car is unstable.
4. Solution; The best way is to clean the oil line, clean it regularly, and use the fuel additives of PNF original liquid to solve the above problems caused by carbon accumulation.
5. Solution: It is recommended to clean the engine carbon frequently.Empty air filter: If it is not replaced in time, it will cause insufficient air intake and lower engine idle speed, resulting in engine shaking. Solution: Replace the empty air filter.
6. Solution: Check whether the spark plug has too much carbon and replace the spark plug. The oil pressure is unstable. If the engine carbon has been removed, the throttle valve has been cleaned, the oil pad and spark plug have been replaced, and the car body is still shaking when idling, it is recommended to go to the 4S store to check whether the fuel supply pressure and intake pressure sensors are normal.
When the road roller starts, the crankshaft cannot rotate mechanical fault diagnosis and repair engine startWhen moving, under the condition that the start-up system is intact, press the start-up switch, the starter makes a noise and the crankshaft cannot rotate, which is a mechanical failure. The reasons why the engine crankshaft cannot rotate are as follows. 1 The starter and the flywheel teeth are not well mesheted.
Cooling system: mainly including water pump, radiator, phoenix fan, water pipe and cylinder block, and water sleeve in the cylinder head. Its function is to dissipate the heat of the high-heat machine parts into the atmosphere to ensure the normal operation of the engine.
The maintenance method of pulling the cylinder of Kubota engine is as follows: the gap between the piston and the cylinder is too small. The lubrication between the piston and the cylinder is poor, and the oil is improperly selected. The piston ring breaks, bites to death on the piston, or the piston spring breaks or falls off.
According to the above description: BMW grid road roller four configurationsWhen repairing the sleeve cylinder, there are precautions that must be mastered: 1. BMW grid road roller four supporting cylinder disassembly to check the cylinder pulling situation and do a good job of measurement to do the maintenance method and boring cylinder treatment.
Are the parts for the overhaul of the Kubota 688 engine cylinder domestic or the original? If it is a domestic part, its accuracy, size, material, hardness and flexibility cannot be compared with those of the original hard factory parts. 2. During the overhaul of the Kubota 688 engine cylinder, did the maintenance master carry out the maintenance according to the Kubota engine maintenance standards?
Engine (diesel engine) cylinder and piston top burning mostly occur at the top of the piston and the second piston ring groove. The main forms of damage include top burning, perforation, pit and keyway notches and collapse around the top.
1. Then the owner needs to drive the car to the 4s store and repair the vicinity of the valve rod or valve duct. After the repair is completed, this situation can disappear.
2. This is caused by the damage of the forced ventilation system of the crankcase. If this happens, the crankcase forced ventilation system must be replaced immediately. If it is not repaired immediately, it will cause more serious failures. When repairing, you must go to a professional maintenance agency. All car engines are equipped with crankcase forced ventilation systems.
3. If the oil leaks at the engine and exhaust junction, the sealing gasket needs to be replaced at the factory. If organic oil seeps out from the connection, it is very likely that your car has a serious oil burning phenomenon. You have to check the engine oil ruler to see if there is less oil. If there is less oil, it is burning oil.
4. The exhaust pipe injection oil is likely to be due to the failure of the piston, cylinder liner, piston pin and piston ring. At this time, it is necessary to find the damaged location and replace it. Don't wait until there is a breakdown to pay attention to it. The consequences can be said to be unimaginable.
5. Turn out of the trachea from the valve cover (because the oil tank is connected to it). In addition, the piston ring is opposite, the piston ring is broken, and the cylinder is pulled, which will cause air leakage. If the amount of oil is insufficient, the oil will become thinner, and the oil will deteriorate, which will make the cylinder seal worse and will also leak air. In the above situation, the engine power will seriously decrease and the fuel consumption will increase.
6. The cylinder pad is damaged. The valve is not tightly sealed. The gap between the valve and the duct is too large. The piston ring tension is insufficient or the piston ring is installed in reverse.The piston is surrounded, and the newly repaired engine is not well run-in. After a period of run-in, the oil drain phenomenon disappears naturally.
