حساس الـ VVT .. علامات تلفه وطريقة فحصه "Variable Valve Timing"

🔴 The VVT sensor or oil control valve is one of the components of the variable valve timing system, which manages oil flow according to engine speed and load and works to improve performance and fuel efficiency. VVT is an abbreviation for Variable Valve Timing, which means variable valve timing, and what is meant is that the sensor makes changes in the valves at specific times. The VVT sensor is currently considered a major part in cars and its purpose is to adjust valve openings. Based on the speed of the car on the road. It also controls the level of air entering the engine and the exhaust leaving it, and when accelerating, the sensor opens the valves more to enter the engine. Larger air volume and therefore better acceleration. Nissan was considered the first to use VVT technology in the 1990s, and now it is a near-universal feature in cars, in order to follow emissions regulations. Car companies have worked to develop it significantly over the past years, such as Toyota, which provided us with an advanced system. Called VVT-i, it was also developed by BMW, Ford and others. VVT is a common technology, but many companies use different brand names and patents for the same system, and each car manufacturer has its own variable valve timing system, and no two systems are the same or alike. Exactly, there are many terms used to describe the VVT systems of different car manufacturers, and we can divide them into two categories, which are incremental and continuous. Progressive systems were mainly used in older cars, and VVT systems were limited to a few functions, usually having a special setting for low and high engine revs. As a result, we can classify most current VVT systems as continuous. Depending on the design, air and fire valves can be opened and the period for which they can remain open can be controlled. If the VVT sensor fails, you will have problems starting your car. In the phenomenon episode, we will learn about the VVT sensor. VVT, its location and how it works in the car... What are the signs or symptoms of damage to the VVT sensor, how to check it... and how to clean the sensor yourself.
