The world's first high-power hydrogen engine has been created in China
China's Weichai Power company has officially certified the world's first hydrogen internal combustion engine for heavy-duty vehicles that meets high environmental standards. This was reported by Zamin.uz.
This new development is expected to be an environmentally friendly and efficient alternative to traditional diesel units. The new technology aims not only to reduce harmful emissions but also to take the use of hydrogen energy in the trucking industry to a completely new level.
This achievement is being widely covered by leading information sources in the field. The new power unit has a volume of 14.6 liters, providing 600 horsepower and a maximum torque of 2800 Newton-meters.
During tests conducted by the China Automotive Research Center, the engine's thermal efficiency was 46.8 percent. This figure is very close to the results of modern high-efficiency diesel engines and is recorded as one of the highest results in the world among hydrogen internal combustion engines.
The main technical feature of the engine is that it is equipped with a direct hydrogen injection system into the cylinders. Supplying the fuel directly into the cylinder rather than through the intake tract allows for precise control of the combustion process.
This method completely eliminates the risk of premature ignition and backfire, which have been among the biggest problems of hydrogen engines. Additionally, this technology contributes to the efficient use of the fuel mixture and reduces energy losses.
In creating the new model, the company's engineers paid special attention to maximum compatibility with existing diesel technologies. According to reports, more than 90 percent of the new engine's components are identical to the company's traditional diesel units.
This allows for minimal modifications to the vehicle structure and significant savings in production costs when converting heavy machinery to hydrogen fuel. Another important aspect is that this engine is not overly demanding regarding fuel quality.
Unlike hydrogen fuel cells, this engine can operate stably even with hydrogen of varying purity levels. This significantly simplifies the process of establishing hydrogen storage and refueling stations, as excessive spending on ideal fuel purification is not required.
Weichai Power plans to use this engine primarily in the industrial and heavy transport sectors. According to experts, the new device is very convenient for trucks operating on highways, dump trucks working in quarries, port equipment, and metallurgical transport.
Furthermore, it can be effectively used in large hydrogen electric generator units. It is worth noting that the hydrogen internal combustion engine should not be confused with hydrogen fuel cells, as it is closer to traditional engines in its operating principle and is more cost-effective.
