Gas and air are mixed in the cylinder, and a set of gas timing injection device is installed in each cylinder corresponding to the intake pipe on both sides. After the main exhaust valve is closed and the main intake valve is opened, the device relies on the timing CAM of the transmission to periodically open the gas valve and spray the gas into the cylinder, so that the gas and air can be mixed in the cylinder (the gas intake volume of a single cylinder can be adjusted according to the exhaust temperature detection of each cylinder), which solves the problem of tempering and firing of the intake pipe. In order to adapt to the characteristics of fast combustion of hydrogen in gas, the double gas valve device is used to shorten the intake time. At the same time, the double gas valve injection can make the refining gas and air fully mixed, and the combustion is more full.
Constant pressure exhaust system
The constant pressure exhaust system is adopted to solve the problem of uneven operation of each cylinder in the pulse exhaust system.
Dual control air-fuel ratio mixing technology
The dual-control air-fuel ratio hybrid technology, which is controlled by air and gas separately, can realize real-time control of spatiotemporal fuel ratio in engine operation. The technology is suitable for the air fuel ratio of most gas
