ACDelco Presents New VVT Solenoids
ACDelco, the main supplier of original spare parts for GM, unveiled the release of aftermarkets’ VVT (variable valve timing) solenoids for cars produced by General Motors.
New VVT solenoids upgraded by GM specialists now can operate twice as long as other competitive products and will come in the market early in the 4-th quarter for cars produced during 2006-2017 with Ecotec engines having the capacity equal to 2, 2.2 and 2.4 liters. For the first time the VVT solution was used by General Motors in the early 2000s and later this technology gained an enormous popularity due to its positive impact on operational characteristics, fuel efficiency and level of emissions.
These
solenoids are intended for monitoring of the
camshaft mechanism parameters
depending on the engine operation mode. Application of the VVT solenoid also
increases parameters of the engine power and transmitted torque. When using
this type of solenoids it is critical to monitor the oil cleanness, because dirty
oil significantly speeds up the wear-out of these solenoids. GM experts
introduced changes in the construction of VVT solenoids that improved the
capacity of resistance to thermal expansion and resulted in longer period of
service.
