Analysis and solution of pre-ignition problem of zero-carbon emission hydrogen fuel engine

At present, many automakers such as Toyota, FAW, Geely, and Dongfeng are developing hydrogen fuel engines. Among them, the thermal efficiency of hydrogen fuel engines developed in China is as high as 46.11%, ranking first in the world. However, the pre-ignition problem is the main obstacle to improving the performance of hydrogen fuel engines. United Electronics has been researching hydrogen fuel engines since 2017 and has provided technical support to many automakers.
