Standard throttle 60 or more valve opening percentage. In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. The continuously variable valve timing VVT system was de-veloped in the early 1990s 1. The benets of using VVT for internal combustion engines include improved fuel economy with reduced emissions In the 1990s, Carrier invented the first variable volume/variable temperature ( VVT) zoning system for heating, ventilation, and air conditioning. Balancing the system. Most VVT system airflow designs are based on cooling requirements which require a greater CFM flow than heating requirements.
