The modern cars have all types of sensors and gadgets, and they also have a central computer system for the smooth operation.
There are so many things going on under the hood, and you don’t even need to know the functions of half of these parts.
However, if you are a car enthusiast, you should know about some important components, and the variable valve timing (VVT) is one of them.
Definition of Variable Valve Timing：
The variable valve timing systems are seen in the internal combustion chamber of an engine.
It does the job of changing the timing of a valve’s opening and closing and works together with the valve lift system.
This component is important because its proper use can enhance engine performance, increase fuel efficiency, and reduce emissions.
The two-stroke engines don’t have a VVT, but they use power valve systems to produce same type of performances.
Important Parts of VVT：
The entire VVT system and its components depend on the engine oil circulation. If there’s any problem with the oil flow, all the parts can fail permanently.
The two most important parts of this system are:
Each camshaft has a solenoid that works on the oil pressure to the camshaft. It can change the pressure based on the engine load and speed.
It also helps to induce the right performance of the engine by enhancing or blocking the cam position.
This component can fail because of two reasons – irregular oil changing in the filters and engine, and low level of oil in the engine.
Also known as cam phaser, this device does the job of maximizing torque curves and enhancing engine horsepower.
It ensures that your car is getting the best performance from the engine while releasing less carbon footprint.
