Variable Valve Timing (VVT) System: Working, Components and Benefits in Modern Engines
Variable Valve Timing VVT We know Internal Combustion (IC) Four-stroke Engine has two engine valves one is called Intake (inlet) and another one is called exhaust (outlet) per engine cylinder. How does the Engine Valve work? The engine valves are doors like devices for opening and closing, for the inhale, air-fuel mixture or air intake the engine cylinder through the intake valve and exhale burned gases exit through exhaust valves. Cam on the rotating camshaft operates the valve train or valve mechanism. Other words intake and exhaust for proper breathing in the smooth engine operation purposes. Before we should know to understand the Valve Timing of the four-stroke engine. The purpose of valve timing is the timing of the opening and closing to the valve about the engine piston position. It depends on the arrangement of valves and valve train or mechanism. There are several different arrangements of valves and valvetrain / mechanism • Location of the camshaft . (the locatio...
