Launch x431 share information
When the engine idling normal oil pressure, medium and high speed operation, the oil pressure fluctuates significantly (oil pressure gauge pointer swing back and forth between 0-0.6Mpa), the main reasons are: 1. The oil pump draws air. When the launch X431 V engine in the high-speed operation, the oil oil suction increases, the air from the oil pipeline seal lax to take advantage of, due to the air is compressible, resulting in oil pressure fluctuations (severe air intake when the pressure). 2. Pressure regulator or Launch X431 v 8 inch return valve spring by foreign body stuck, or spring bending and seat hole rub, so that the spring movement blocked, the ball valve opening and closing are more difficult. When the main oil in the xtool x100 pad2 pressure increases, the ball valve is open, the main oil back pressure, but the spring block effect until the oil pressure is very low or even close to zero when the ball valve was closed, then the main oil pressure , The ball valve and ...
