Generally speaking, the exhaust pipe of motorcycles has the condition of spraying white smoke, which is caused by the fact that the motorcycle is old, or is usually neglected by maintenance. To put it simply, a four-stroke motorcycle will automatically open the choke valve during the hot motorcycle phase. When the engine is started, the idle speed will be higher than normal, so sometimes it will produce a faint white smoke or the exhaust gas will be converted into a catalytic converter. The motorcyclebon dioxide and water, this kind of normal condition, and the two-stroke motorcycle because the engine lubrication method is spray oil, that is, the oil and gas oil will be mixed and burned. The sprayed oil is a mixed oil and gas that atomizes gasoline and oil together. It first lubricates the cylinder bore and the crankcase, and then enters the combustor to burn into the combustion chamber. The oil is discharged after burning with gasoline, and similarly, it will produce a faint white. smoke.
However, if the cylinder or valve oil seal is damaged, the oil will leak into the cylinder, the oil pump will age and pressurize too much oil for the cylinder to burn, the ignition of the spark plug is not normal, resulting in incomplete combustion of the gasoline, and the throttle of the oil pump. The valve screw is adjusted too large, and the long-term short-distance riding, the engine does not reach the optimal working temperature, the flame is stopped, the waste particulate molecules generated by the incomplete combustion are adsorbed in the oil, or the burned oil is accumulated in the exhaust pipe. The probability that the exhaust pipe produces white smoke is even greater. At this moment, the best way to eliminate it is to send it as soon as possible, because there is such a situation, it is not formed in three or two days.
In order to prevent the white smoke of motorcycle exhaust pipes, in addition to the daily attention to the motorcycle conditions, regular maintenance and oil change are also very important. In addition, the details of the hot motorcycle before riding and the correct riding rule can not be ignored. Remember! If the motorcycle is aware of the difference, don't worry about solving the problem in a hurry. If you seek professional assistance, you won't be afraid of it!
