VariabelVentilzeiten
VariabelVentilzeiten, often abbreviated as VVT, refers to a technology used in internal combustion engines that allows for the adjustment of the timing of the intake and exhaust valves. This adjustment is not fixed but can be altered dynamically based on engine operating conditions, such as engine speed and load. The primary goal of VVT is to optimize engine performance, fuel efficiency, and emissions across a wider range of operating scenarios than a fixed valve timing system.
Traditional engines operate with a fixed valve timing, meaning the valves open and close at the same
There are several types of VVT systems, including hydraulic, electric, and mechanical. Hydraulic systems, the most
