Diesel Engines Converted To Hydrogen
Today there is a question whether the diesel engine can be changed to hydrogen drive. Everyone says that the structure of the diesel engine is different from the characteristics of hydrogen. Diesel combustion depends on pressure ignition, while hydrogen has a low ignition point and fast diffusion, and its combustion method is mostly ignition. To change the diesel engine to hydrogen drive, many key points need to be changed.
The first to bear the brunt is the fuel supply system. Diesel injection is precisely timed and pressurized to adapt to diesel viscosity and injection characteristics. Hydrogen has low density and strong fluidity. A new supply system is required to precisely control the amount of hydrogen and the injection time to ensure stable and efficient combustion.
Furthermore, the ignition system. Diesel engines have no spark plugs, and diesel spontaneously ignites by compression and heating up. After changing to hydrogen, due to the high spontaneous combustion temperature of hydrogen, a reliable ignition device needs to be installed, such as spark plugs or high-energy ignition systems, to ignite hydrogen in a timely manner to promote smooth combustion.
In addition, the engine compression ratio also needs to be determined. Diesel engines have high compression ratios and are suitable for diesel compression ignition. If the hydrogen compression ratio is too high, it is easy to cause early combustion, knock and other defects. It needs to be adjusted according to the combustion characteristics of hydrogen to ensure the smooth operation of the engine.
In addition, hydrogen is flammable and explosive, and safety protection cannot be ignored. From hydrogen storage, transportation to engine use, strict safety measures are required in all aspects, such as high-strength hydrogen storage containers, tight hydrogen pipelines and multiple safety monitoring and early warning devices.
In short, diesel engines to hydrogen drive, although facing many challenges, but the technology is advancing, if the above problems can be overcome, it is of great significance for energy transformation, environmental protection and emission reduction, or for the future development of power.
