What is the most painful thing about riding your beloved motorcycle? This means that the engine suddenly shuts off when you are on the road. If you go to and from work, it will delay your return from work; if you go out on a date, it will drag you down; to be punctual ; if you go out to have fun, it will spoil your mood for fun; If you're going on a motorcycle trip, I won't go into details...
When the car. suddenly stalls, there are usually two big problems, the oil line and the electrical circuit.
1. Be sure to check for oil! ! !
You must mean: don't make trouble. How could you not be aware of a problem as simple as low oil? Does it all depend on the instrument? No, no, no, I really didn't make a fuss. One time the meter showed I was almost out of gas. I forgotto stock up because I was busy. Then, while I was waiting for the fire. at the intersection it suddenly went out and the engine could not start. So I stupidly hit it several times at the intersection, the car behind kept honking and finally realized it was out of fuel and quickly opened the spare fuel tank. tank... The editor naively believed that there must be someone like me.
The engine speed will suddenly increase automatically before the fuel runs out and stalls at a high level (the throttle grip is not filled with oil), this phenomenon is easy to feel when driving at low speed and can be confirmed by stopping the car and checking whether there is oil in the fuel tank .
2. Fuel cannot be supplied normally.
In this case, the power will seem insufficient and will gradually decrease before parking, possiblyis it will gradually stop automatically. At this time, after confirming that there is oil in the fuel tank, check if there is oil in the carburetor. If there is no oil, it means the oil line from the fuel tank to the carburetor is blocked and needs to be cleaned. outlet. If there is oil in the carburetor and it still cannot start, you need to check whether the carburetor oil filter is clogged and whether there is dirt in the main measuring hole. If it can start you can't leave it at that, it means there is a fault in some part of the fuel system that has not been discovered and the fuel system line needs to be completely cleaned. Otherwise, the engine could stall automatically and the malfunction could recur.
3. Engine temperature is too high.
Excessive temperature and excessiveImproper lubrication can cause the piston and cylinder to seize, which can also lead to flameout. The signs before stalling are a gradual decrease in power at first then a sudden stop. After diagnosis, you must first check whether there is lubricating oil in the crankcase. If there is little or no lubricating oil, you need to check whether the oil pan or oil drain plug is leaking. Find the fault and correct it, then. add the specified amount of lubricating oil. If it is not an oil leak problem, check whether the lubricating oil is excessively consumed and add or replace the lubricating oil in time.
4. Circuit failure.
Automatic shutdown caused by a sudden power failure in the circuit. There will be no abnormality in the engine before the sudden stop. The causes of sudden motor power loss usually occur at the nlevel of wiring, such as loose connectors, wire breaks, short circuits, etc. For example, if the ignition coil is faulty, the ignition coil connector may be loose and misfiring. You need to check each connector, remove oil stains, increase the clamping force of connectors and seats, and increase contact. Force to ensure stable contact. The trigger coil is faulty, the trigger coil lead seal is loose, and misfires occur. The strength of lead soldering should be strengthened to completely eliminate the hidden danger of false soldering.
Then check the reasonThe troubleshooting steps are as follows: first check the battery wiring and low voltage wire ends, then check if the high voltage wires have fallen on the spark plug and the end of the ignition coil, and check them with an experienthis bypass. When the battery is exhausted or the connection wire is loose but not disconnected, the engine also stalls automatically, but the signs before stalling are different from the sudden circuit break. At first, the engine suddenly goes up and down, and the motorcycle suddenly rushes. Once the throttle is lowered and the speed becomes low, the engine will automatically stop. Indeed, when the engine speed is high, the generator provides energy for ignition and the engine continues to run. If the speed changes, the generator output current also changes, causing the ignition to cut and the motorcycle to race when the throttle is activated. is lowered, the speed decreases, the generator is not producing electricity or the current is low, the spark plug cannot ignite, causing the engine to stall. At this point, you should first carefully check the condition of each wire joint to ensure youmake sure there is no play, then measure the battery power and charge it according to regulations.
5. The clutch or other parts are blocked.
When the screws on the clutch support disc are not tightened and the safety riveting points are not properly flushed and the safety function cannot be achieved, the screws will loosen more and more as the engine runs, causing the screw heads to press against the transmission pair. The shaft bearing cover and clutch are stuck and cannot rotate, causing a sudden stop. In this case, first remove the transmission and check if the clutch is loose, then dispose of it. When the transmission gear is broken and its fragments get stuck in the transmission, or the transmission chain becomes loose and stuck on the main shaft sprocket, it will cause a sudden stop. Therefore,when the engine suddenly stalls, you must first find the problem and then eliminate it one by one.
