NTK’s program approach focuses on high failure rate applications of VVT solenoids in vehicles that are 2004 model year and newer.
Ranging from 2007-2019, the kits and components are available for popular makes and models.
Steve Burke will be speaking about Schaeffler’s variable cam timing products that are custom designed for automotive OEM vehicle engines. More specifically, he will share some of his experience on the design and development that went into the VCT system found on the Ford 5.4L-3V V8 engine.
Variable Valve Timing (VVT) has been incorporated into many late model import and domestic engines, including single overhead cam (SOHC), dual overhead cam (DOHC) and even pushrod V8s such as GM’s GEN IV 5.3L and 6.0L engines. It is a technology that offers performance, emissions and fuel economy advantages for everyday driving, but it also creates some challenges for engine builders.
There’s no doubt that engine specialists will begin seeing more variable valve timing (VVT) designed engines in their shops, as the generation of vehicles equipped with this technology begins to make its way into the service industry. In fact, the current versions of VVT were popularly introduced into domestic production about 10 years ago. Operating
Variable Valve Timing (VVT) is a way to advance/retard valve timing, and change duration, overlap and even lift in some applications while the engine is running. VVT is computer-controlled and typically uses oil pressure to change the position of a phaser mechanism on the end of the camshaft to advance or retard cam timing. VVT
