Improving power and torque: VVT components can correctly open the valves in advance according to different operating conditions of the engine, such as when power is needed for high-speed driving, increase the intake volume, and fully
VVT components refer to the variable valve timing system of automotive engines, which have the following characteristics:
Significant performance improvement:
Improving power and torque: VVT components can correctly open the valves in advance according to different operating conditions of the engine, such as when power is needed for high-speed driving, increase the intake volume, and fully burn the fuel in the combustion chamber, thereby effectively improving the power and torque of the engine and providing stronger power output for the vehicle
Optimizing fuel economy: When driving at low speeds or idling in congested urban conditions, VVT components will appropriately delay the valve opening time, reduce the valve overlap angle, and control the engine's intake volume reasonably, thereby reducing fuel consumption, improving fuel economy, and helping car owners save fuel costs
Combustion process optimization: By adjusting the opening and closing time of the valves, VVT components can create a more ideal ratio and flow state of the mixture in the combustion chamber, making combustion more complete and stable. This not only improves the efficiency of the engine, but also reduces the emissions of harmful gases such as carbon monoxide and hydrocarbons produced by incomplete combustion, reducing environmental pollution and better meeting increasingly strict environmental emission standards
Idle stability enhancement: VVT components can adjust valve timing correctly according to the actual operating state of the engine, maintain stable combustion state at idle, effectively reduce engine vibration and noise, improve vehicle comfort, and reduce the vibration and noise interference felt by drivers and passengers inside the car
Wide adaptability: VVT components can automatically and quickly adjust valve timing according to various operating parameters such as engine speed, load, temperature, etc., ensuring that the engine can maintain good performance under various working conditions. Whether starting in cold winter, driving in hot summer, or at different altitudes and road conditions, they can adapt and optimize engine operation
High level of technological integration: The VVT system consists of multiple components such as sensors, control units (ECU), actuators, and related mechanical parts, which require highly accurate collaborative work and information exchange between these components. Through complex electronic control systems and precise mechanical structures, the correct control of valve timing is achieved, reflecting a high level of technological integration and an important manifestation of the continuous progress and development of automotive engine technology
The maintenance cost is relatively high: Due to the complex structure of VVT components, which include numerous electronic components and precision mechanical devices, once a fault occurs, its diagnosis and maintenance are relatively difficult, requiring professional technicians and equipment for inspection and repair. Moreover, the price of related components is relatively high, which will lead to an increase in the maintenance cost of the vehicle.
