AI Technical Summary
In existing internal combustion engine hydrogen mixing and circulation systems, the amount and speed of hydrogen delivery cannot be properly controlled, leading to phenomena such as pre-ignition and affecting combustion efficiency.
By employing a hydrogen metering valve and hydrogen injectors, combined with a mixing device, the amount of hydrogen input is precisely controlled and the delivery is accelerated to form a stable combustible hydrogen mixture. The hydrogen is precisely controlled by the hydrogen metering valve and hydrogen injectors, and combined with the mixing burner, a stable combustible hydrogen mixture is formed.
It enables precise control of hydrogen delivery, improves combustion stability and safety, reduces resource waste, and enhances combustion efficiency.
