In addition, out of the 11 sub-indexes this month, only the finished goods inventory index increased by 52.2% month-on-month, which was 2.7 percentage points higher than last month and rose above the critical point. Some enterprises have reported that due to the lack of market demand and poor product sales, the inventory of finished products has been overstocked, the return of funds has been difficult, and production and business activities have been affected.
Variable Valve Timing Solenoid
Variable valve timing (VVT) solenoid or oil control valve controls the oil flow according to the engine speed and load. VVT solenoid is a vital part of the variable valve timing system.
The Oil Control Valve (OCV) is a a critical part used in every engine that is fitted with variable valve technology (VVT). A single control valve will regulate the supply of oil to a designated VVT hub, to advance or retard the timing by altering the camshaft angle position. Controlled by the ECU, the OCV receives electrical signals, instructing it to adjust the oil flow as required, in accordance to current driving conditions.
