1.Optimize power output：At low engine speeds, it can appropriately delay the closing of the intake valve, using the inertia of the intake airflow to allow more fresh air to enter the cylinder, making the air-fuel mixture more sufficient and the combustion more complete, thereby increasing low-speed torque and making the vehicle start more smoothly. At high engine speeds, it can advance the opening of the exhaust valve or accurately match the intake and exhaust phases, effectively expelling exhaust gas, optimizing intake efficiency, and enhancing power output at high speeds, making acceleration and overtaking more smooth.

2.Improve fuel economy：By accurately controlling the timing of valve opening and closing, it reduces pumping losses. At the same time, it makes the mixing of fuel and air more uniform and combustion more efficient. Under medium and low load conditions, the fuel-saving effect is significant, reducing fuel consumption and lowering usage costs.

3.Reduce exhaust emissions：Precise valve timing control can optimize the valve overlap angle, promote the mixing of oil and gas, and reduce harmful substances such as carbon monoxide and hydrocarbons generated by incomplete combustion. It can also effectively manage exhaust gas recirculation, lower the combustion temperature, and inhibit the formation of nitrogen oxides, making vehicle exhaust emissions more in line with environmental protection standards.
