How is the variable valve timing VVT camshaft actuator controlled?
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.
Can I disable VVT?
Eliminating the VVT system is required when swapping to a non-VVT camshaft. These cams offer higher valve lift and longer duration for more performance. A VVT delete kit removes the VVT components and replaces them with standard parts.
Should I delete VVT?
As for keeping or deleting VVT, the benefit of keeping VVT is that you gain low end torque. The drawback is that you lose high end hp compared to a LS3 cam. Many people swear up and down that a VVT cam is the way to go, while others swear up and down to delete VVT and do a LS3 conversion.
What does a VVT delete do?
A VVT Delete Kit removes the VVT components and replaces them with standard parts. A new, 4X, non-VVT upper timing gear, A new harmonic balancer bolt, and. New camshaft bolts.
What kind of exhaust cam gear does a Volvo 5 cylinder have?
Volvo 5 cylinder Cars With VVT… Exhaust Cam Gear V40 and S40 (2004+) owners rejoice! Help and advice is here for you while you’re working on your Volvo’s timing belt. This is also applicable to 2000s Volvo 5-cylinder cars with VVT… variable valve timing.
Can a non-VVTi cam gear be replaced?
The same process can be followed on the non-vvti, the VVTi has only the exhaust side cam gear that can be replaced, the non-vvti can have the exhaust and intake cam gear swapped out.
What does variable valve timing ( VVT ) do?
Variable Valve Timing (VVT) is used to vary engine performance and enhancements. On dual cam systems, the PCM controls the amount of variance on both cams separately. There are two actuators in the system; one for the exhaust cam and one for the intake cam.
How do you set the CVVT on a Volvo?
Lock the cams in place and make sure the crank shaft marks are correct. Line up the intake cam to the timing cover, then rotate the CVVT hub clockwise to see where your current timing marks align. This will tell you how far forward/back you need to adjust the hub. Remove the center bolt and rotate the hub as necessary.
