What is Hyundai CVVT?

What is Hyundai CVVT?

Continuous Variable Valve Timing (CVVT) is a valve-timing technology that controls the timing of a valve lift event and is often used to improve performance, fuel economy or emissions. early intake valve closing during the intake stroke increases the volume of air-fuel mixture, engine output increases.

What does a VVT controller do?

Exhaust camshaft is driven by the timing belt and intake camshaft is driven by gear on the end of exhaust camshaft. Intake camshaft drive gear is integrated with the variable valve timing controller to vary intake camshaft valve timing.

What is the difference between CVVT and VVT?

VVT: it is a variable valve timing; CVVT: continuous variable valve timing; The translation into Chinese is a continuous variable valve timing mechanism. It is one of the many variable valve timing technologies that have been gradually applied to modern cars in recent years.

How does a CVVT engine work?

CVVT engine system adjusts the intake valve timing longer at higher rpm. With the advanced intake valve and longer delayed exhaust, it allows more air entering the engine at higher rpm. It delivers optimum air-fuel mixture fully filled the combustion chamber and the oil efficiency improves.

How does the CVVT work in a Hyundai Sonata?

The CVVT has the mechanism rotating the rotor vane with hydraulic force generated by the engine oil supplied to the advance or retard chamber in accordance with the CVVT oil control valve control. Catalytic Converter. Description and Operation Description The catalytic converter of the gasoline engine is a three way catalyst.

How does CVVT work on a Hyundai Veloster?

Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load.

How does a Hyundai CVVT oil control valve work?

Spacing between the OCV power and signal terminals is very narrow. Use suitable connections to prevent shorting of the test power supply. 3. When 12V power is provided to the OCV, the OCV must move forward as shown in the following photo. 4.

How does the cvvd system work in a Hyundai?

The CVVD system consists of a variable control unit and a drive motor on the camshaft. While ECU turns the CVVD drive motor up to 6000rpm, the variable rotating adjuster moves up and down in 0.5 seconds, and shifts the contact point of the cam lobe, determining how long a valve is open.
