Domestic gas engines have persisted in independent research and development, focusing on key areas such as combustion efficiency, core components, electronic control systems, fuel compatibility, and intelligent low-carbon technologies.
Domestic gas engines have persisted in independent research and development, focusing on key areas such as combustion efficiency, core components, electronic control systems, fuel compatibility, and intelligent low-carbon technologies. Through systematic technological innovation, they have achieved performance improvements and self-control.
In terms of efficient combustion and heat efficiency enhancement, the company has focused on researching and developing technologies such as equivalent combustion, high-pressure injection, turbulent combustion chambers, and efficient ignition. It precisely controls the air-fuel ratio, significantly improving fuel utilization. Several main models have achieved international advanced levels in thermal efficiency, balancing power and economy while meeting the strict emission requirements of the sixth stage.
In terms of the autonomy of key core components, the industry has been striving to overcome "critical" components such as high-temperature alloy materials, high-performance turbochargers, high-strength cylinder blocks and covers, and long-life spark plugs, achieving a transition from reliance on imports to self-supply, effectively enhancing reliability and durability, and reducing the overall cost and maintenance difficulty.
Intelligent electronic control and system integration have become an important innovation direction. The company has independently developed engine ECU electronic control systems, achieving precise control in all operating conditions and adapting to complex conditions such as high altitudes, low temperatures, and heavy loads. At the same time, it promotes platform-based and modular design, quickly adapting to various scenarios such as heavy trucks, ships, power generation, and industrial mines, improving adaptability and production efficiency.
Facing multi-fuel and low-carbon/zero-carbon transformation, domestic gas engines are continuously expanding fuel adaptability, being able to stably use various fuels such as natural gas, coalbed methane, biogas, and industrial by-products. They are also conducting research and development on hydrogen blending combustion and pure hydrogen combustion, laying out the next-generation zero-carbon power, and helping to achieve the "dual carbon" goals.
In the fields of digitalization and intelligent operation and maintenance, through technologies such as big data, remote monitoring, fault warning, and predictive maintenance, the engine's entire life cycle management is realized, improving operational stability and service efficiency.
A series of innovative measures have enabled domestic gas engines to gradually break free from foreign technology monopolies, moving from lagging behind to parity and leading, providing solid support for the self-control and green development of high-end equipment.
