Types of VVT

The VVT produced by our company mainly include the following types:

VVT FOR Volvo
The principle of engine variable valve timing technology is to adjust the amount of intake (exhaust), valve opening and closing time, and angle based on the operation of the engine. Maximize the amount of air entering and improve combustion efficiency.

VVT FOR Renault
It is worth noting that the commonly used VVT systems in China are mostly driven by hydraulic pressure, which mainly consists of key components such as phase shifters, engine oil regulating valves, actuators, and regulators.

VVT FOR Fiat
VVT (Variable Valve Timing) is the technology for engine variable valve timing. The principle is to adjust the amount of intake (exhaust), valve opening and closing time, and angle based on the operation of the engine.

Advantages of VVT

Maximum power output

Which is essential in performance-focused applications

Smoother idling

That enhances the driver's experience, comfort, and noise in the vehicle

Reduced emissions

To keep up with today's focus on eco-friendly alternatives

Improved torque

When operating at low RPMs, VVT allows the engine to be more responsive

Fuel efficiency is enhanced

VVT offers better fuel efficiency without sacrificing power, which is optimal in many applications

Applications of VVT

01/

Automotive Industry
Passenger Vehicles: VVT technology is widely used in passenger vehicles to enhance fuel efficiency, improve engine performance, and reduce emissions. By adjusting the timing of the intake and exhaust valves, VVT systems can optimize the engine’s operation across different driving conditions. For instance, the use of VVT in gasoline engines can lead to a significant increase in torque and power output, as well as improved fuel economy and reduced exhaust emissions.
Motorcycles: VVT technology is also applied in motorcycle engines to achieve similar benefits. For example, the Jialing JH125 motorcycle engine has been studied for the application of VVT, resulting in optimized valve timing and improved engine performance.
High-Performance Sports Cars: High-performance vehicles, such as the Lamborghini V12 engine, utilize VVT systems to achieve better torque across all speed ranges, enhance fuel economy, and reduce emissions. The Power-Oriented Graph (POG) technique has been used to model and validate the effectiveness of VVT in such applications.

02/

Commercial Vehicles
Light-Duty Diesel Engines: VVT technology is increasingly adopted in light-duty diesel engines to meet stringent emission regulations. By employing strategies such as exhaust re-opening and late exhaust closing, VVT systems can increase the efficiency of diesel oxidation catalysts and reduce pollutants like CO, HC, and NOx emissions.

03/

Industrial Applications
Stationary Engines: VVT systems are also used in stationary engines for power generation and industrial applications. These systems help in optimizing the combustion process, leading to better fuel efficiency and reduced emissions.

04/

Emerging Applications
Hybrid and Electric Vehicles: While primarily used in internal combustion engines, VVT technology is being explored for hybrid and electric vehicles to optimize the performance of range extenders and improve overall vehicle efficiency.

Precautions for Using VVT

Regular oil changes

The VVT system relies on clean oil to function properly, so make sure to change your oil regularly.

Low oil levels can cause grave issues

These include damage to the VVT chain, solenoid, and gear drive, etc

Avoid/Stop sludge buildup

Dirty oil can clog internal passages and disrupt valve timing, so make sure to keep a lookout.

Use the correct oil grade and weight

Especially important for VVT systems controlled by the ECU.

Proper oil pressure

The system uses oil pressure to advance or retard valve timing, so make sure to keep it in check.

VVT systems are electronically controlled

Make sure your ECU is functioning correctly, otherwise it won’t be able to control it.

Manufacturer-recommended service intervals

Stick to these, especially for oil and filter changes.

Look for irregular engine noises

Rattling or ticking could point to worn VVT components, so keep a lookout for these as well.

Get diagnostics done if performance drops

Poor acceleration or fuel economy may sometimes trace back to VVT issues, so diagnose it if you can.

FAQ

Q: What Does VVT Stand For?

A: VVT stands for Variable Valve Timing, a modern engine technology that adjusts valve opening and closing for better performance and efficiency in all driving conditions.

Q: How Does VVT Improve Fuel Economy?

A: VVT optimizes intake camshaft valve timing regarding overall engine load and engine speed, improving fuel efficiency, reducing emissions, and enhancing combustion, all of which lowers the total MPG count.

Q: What is the Difference Between VVT and VTEC?

A: Variable camshaft valve timing adjusts timing continuously, while VTEC (Variable Valve Timing and Lift Electronic Control) switches between two cam profiles depending on whether the driver wants better performance or efficiency.

Q: Can You Upgrade a Non-VVT Engine to VVT?

A: Although technically possible, it requires a great deal of work, effort, and money: a new ECU, camshafts, camshaft sensors, and extensive software and hardware modification.

Q: What are the Symptoms of a Failing VVT System?

A: The most common symptoms of a failing variable valve timing system include rough idle, poor fuel economy, check engine light, engine knocking, and engine stalling.

Q: Does VVT increase horsepower?

A: Yes, variable valve timing (VVT) can increase horsepower, along with improving fuel efficiency and reducing emissions. By adjusting valve timing, VVT allows an engine to optimize its performance across a wider range of engine speeds and load conditions, leading to increased power output.
