What is VVT gear?
More & more vehicles are equipped with VVT cam gear to improve fuel economy performance. The electronic technology allows right amount of oil supply to get into engine via variable valve timing solenoid adjustment. Automakers have their own names to this technology. Ford calls it Variable Camshaft Timing, VCT.
What do adjustable cam gears do?
Adjustable camshaft gears allow you to tweak the conservative factory settings for increased power and driveability. Adjustable cam gears also give the user the ability to shift peak power throughout the rpm range, a big plus if you are a low-end city driver, mid-range autocrosser, or high-rpm drag racer.
Are adjustable cam gears necessary?
The OEM cam gears are made for a comfortable ride with a set amount of horsepower and torque (more like intake and exhaust timing) and don’t need to be adjusted. Aftermarket ones are made adjustable so you can get the most most horspower and torque out of your car as possible.
How does a VVT gear work?
Basically, it varies the valve timing by shifting the phase angle of camshafts. For example, at high speed, the inlet camshaft will be rotated in advance by 30° so to enable earlier intake. This movement is controlled by engine management system according to need, and actuated by hydraulic valve gears.
What does VVTi stand for?
Variable Valve Timing-intelligent
Tokyo―TOYOTA MOTOR CORPORATION announced today the development of its new “Variable Valve Timing-intelligent” (VVT-i) technology, which increases performance and fuel economy. Engine development today necessitates both better fuel economy and advanced vehicle performance.
At what RPM does VVT kick in?
When the engine is operating above 6000 rpm, the ECU activates an oil pressure switch which pushes a sliding pin under the slipper follower on each rocker arm. This in effect, switches to the high lobe causing high lift and longer duration.
What does a bad VVT sound like?
Rattling Noise From the Engine A faulty VVT solenoid can prevent the VVT actuator from getting the oil pressure it needs. When this happens, you may hear a rattling noise or ticking noise from the engine. A rattling noise from the engine may indicate a bad VVT solenoid.
Why do you need an adjustable camshaft gears?
Adjustable camshaft gears are the perfect combination for sports camshafts in engine tuning. Since high-lift cams have different control times due to a modified contour, adjustable camshaft gears are needed for this.
Can a camshaft be adjusted for rigid control?
While the adjustment of a conventional camshaft gear only permits rigid control times, the optimum control time of a sports camshaft is exactly in between. This value can be easily reached with an adjustable camshaft gear. In our shop, you get matching gears for many engines, e.g.: Im Lager. Im Lager. Im Lager. Im Lager. Im Lager. Im Lager.
