Diesel Engine Hydrogen Conversion
Diesel engines change to burning hydrogen
In today's world, the change of energy is imperative. Diesel engines have strong power, but high energy consumption and heavy pollution. Hydrogen energy is clean and efficient, and it is the choice of future energy. Therefore, diesel engines change to burning hydrogen, which has attracted much attention.
The structure and principle of diesel engines use diesel as fuel, compress and spontaneous combustion, and use biomass to drive machinery. Its structure is precise, and all components work together to form a complex power system. Hydrogen fuels are different. Hydrogen has a low ignition point, fast flame propagation speed, and is easy to ignite and explode when mixed with air. To change diesel engines to burn hydrogen, it is necessary to study the differences between the two and find a feasible way.
Diesel engines burn hydrogen, there are many problems to be solved. First, the fuel supply system. Diesel is a liquid, and it is precisely injected through the fuel injector. Hydrogen is a gas with low density, which is difficult to store and transport. New methods must be innovated to ensure that hydrogen is stable and accurate into the cylinder. Second, the ignition system. Diesel spontaneously ignites, while hydrogen needs external ignition. Ignition devices must be added, such as spark plugs or high-energy ignition systems, to ensure that hydrogen explodes in a timely manner to provide stable power. Third, engine materials. Hydrogen burns at high temperatures and pressures, and some components are prone to corrosion and damage. Corrosion-resistant and heat-resistant materials must be selected, or the structure of components must be optimized to increase the durability of the engine.
Although there are many problems, researchers have made progress in their unremitting exploration. We have developed a dual-fuel system that uses both diesel and hydrogen. At low loads, hydrogen is the main one to reduce emissions; at high loads, diesel is supplemented to supplement power. This system takes into account engine performance and emissions, and is a transition plan. There are also improved engines that burn all hydrogen. After optimizing the intake and compression ratio, the hydrogen combustion efficiency is improved and the engine power is increased.
Looking to the future, if the diesel engine changes to burning hydrogen, there will be many benefits. In terms of the environment, it will greatly reduce pollutant emissions, such as particulate matter, nitrogen oxides, etc., slow down air pollution and protect the ecological environment. In terms of energy structure, reduce dependence on traditional fossil energy, expand energy sources, and promote energy diversification. In the economic field, with the maturity of technology, costs may decrease, increasing product competitiveness and promoting the development of related industries.
In short, diesel engines are converted to burning hydrogen, which is an important direction for energy transformation. Although the road is long, adhering to the scientific spirit and continuous innovation will surely be able to solve problems, achieve the vision of clean and efficient power, and seek well-being for the development of human society.
