Dolcera Report: Variable Valve Timing (VVT)


Variable Valve Timing is an important phenomenon in all reciprocating internal combustion engines. Valves are used to control the amounts of intake air or charge, thereby operating the engine without any interruption. Earlier valves open and close at a particular engine rpm. The timing of these valves is independent of engine speed. This leads to reduced engine performance.

 

With the advent of improvements in this technology over the years VVT not only improves engine performance but also reduces harmful emissions, improves fuel economy. Hence in order to improve engine performance, auto giants came up with the concept of Valve timing.

 

FIAT first patented on this valve timing technology in 1960. But it took almost 20 years for this technology to transform into practicality. Alfa Romeo became the first car to use this technology in its cars in 1980.
