Ø In cylinder mixing technology (safety):
      Gas and air are mixed in the cylinder, and a set of gas timing injection devices is installed in each cylinder corresponding to the intake pipes on both sides. After the main exhaust valve is closed and the main inlet valve is opened, this device relies on the timing cam of the transmission to open the gas valve at a fixed time to inject gas into the cylinder, allowing the gas and air to mix in the cylinder (the gas intake volume of a single cylinder can be adjusted based on the exhaust temperature detection of each cylinder), solving the problem of backfire blasting in the intake pipe. In order to adapt to the fast combustion characteristics of hydrogen in gas, a dual valve device is adopted to shorten the intake time. At the same time, the dual valve injection can fully mix the refining gas and air, resulting in more complete combustion.
