"Ace Power: Yuchai's Multi-Fuel Low-Carbon and Zero-carbon Intelligent Engine Goes Viral

With the proposal of the global carbon peaking and carbon neutrality goals, there is a more urgent demand for the research and application of green and low-carbon energy vehicles. More and more people are also concerned about where the development direction of fuel vehicles lies.

As the largest independent internal combustion engine manufacturing enterprise in China, Yuchai engines have a wide range of matching applications and serve as the "middle platform" and "back office" of power technology in China's automotive, construction machinery, agricultural machinery, shipbuilding and power generation sectors. In order to provide strong support for the "front stage", Yuchai, in addition to traditional diesel and low-carbon natural gas engines, also offers product and technical support to related industries in the flexible utilization of carbon-neutral fuel methanol and zero-carbon fuels such as hydrogen and ammonia.

In the technological exploration of green and low-carbon alternative fuels, Yuchai has always been at the forefront of the industry. Recently, major breakthroughs have been made successively in the application of ammonia fuel and methanol fuel, and the development and application of Yuchai's multi-fuel engine platform have taken new steps.

The multi-fuel engine technology platform has opened up a new realm for the development of internal combustion engines

Yuchai is the first multi-cylinder internal combustion engine manufacturer in China to exceed 10 million units in production and sales. Based on over 70 years of R&D, manufacturing experience and technological accumulation, Yuchai has launched a multi-fuel engine platform, which is also a key technical platform that supports and promotes the realization of zero-carbon and intelligent technologies.

In comparison, this platform can apply a variety of fuels, significantly lowering the technical threshold and application cost of low-carbon and zero-carbon fuels such as hydrogen. At the same time, as most structural components are universal, it can reduce the development and manufacturing costs of vehicle manufacturers. It is a technical solution for whether large-scale industrialization can be achieved in the short term under the current background of carbon peaking and carbon neutrality. This also opens up a new path for the internal combustion engine industry to meet challenges.

Embark on the path of ammonia-hydrogen engine development that carries the glory of internal combustion engines

In the current era, hydrogen energy, with its inherent advantage of zero carbon emissions, has become an important way to achieve "carbon peak" and gradually reach "carbon neutrality".

At present, there are still technical bottlenecks in the large-scale and low-cost application of hydrogen energy, but it is an inevitable trend for hydrogen energy to step onto the stage of the energy market. To address the related technical and cost bottlenecks, hydrogen-burning engines offer new zero-carbon solutions for application fields such as commercial vehicles and construction machinery.

In recent years, the R&D team of Yuchai has been constantly promoting the technological progress of hydrogen-burning engines by overcoming problems such as backfire, pre-ignition, knocking, hydrogen embrittlement, low exhaust temperature and high water content. In the next three to five years, Yuchai's hydrogen-burning engines will cross the product thresholds of durability and reliability, gradually achieve marketization, and the comprehensive performance indicators such as thermal efficiency will reach the international leading level.

In addition, for zero-carbon ammonia fuel engines, Yuchai has developed multi-fuel co-firing injection systems based on its years of engine development experience. These systems not only make up for the shortcomings of ammonia such as slow combustion speed and high ignition energy requirements, but also leverage the environmental protection advantages of ammonia fuel with zero carbon emissions, thus having broad market prospects.

The technologies of methanol single-fuel and methanol-diesel dual-fuel engines can be implemented relatively quickly

Methanol remains liquid at normal temperature, is safe to use and easy to transport. Meanwhile, green methanol is a carbon-neutral fuel and is currently the most advantageous green fuel. Methanol fuel, with its unique advantages, is regarded as one of the new alternative fuels that best suit China's current energy and resource conditions.

A large amount of basic research, experimental verification and operational data have proved that methanol, as an automotive fuel, has good safety, economy and environmental friendliness.

Recently, relevant methanol vehicle displacement applications have been made in our country. Compared with diesel vehicles, the fuel cost of this batch of methanol heavy-duty trucks can be reduced by 18%. Based on an annual driving distance of 150,000 kilometers, it can save 45,000 yuan in fuel costs each year. With its product advantages, the development of methanol heavy-duty trucks may usher in a new spring. In Xinjiang, Inner Mongolia and other places, methanol has a significant cost advantage. It can be foreseen that methanol mining trucks will be widely promoted in these areas.

According to relevant technical personnel, based on the existing technical reserves, Yuchai can quickly realize the technical implementation of the M100 methanol fuel for vehicles and the methanol-diesel dual-fuel engine.
