In Dalian, China delivers the 8G95 LNG marine engine with integrated EGR for ultra-large container ships and says it complies with IMO standards without needing external devices.
China delivered its first 8G95 liquefied natural gas (LNG) dual-fuel engine manufactured in Chinese territory in Dalian, Liaoning Province, in the country’s northeast. The delivery took place on April 21, 2026, marking an advance in the country’s capacity to produce dual-fuel marine engines in this power range.
The new marine engine was developed to be installed in ultra-large container ships, with capacities for 24,000 TEUs and 21,000 TEUs. Its size and power explain its prominence: it is a 16-meter-high piece of equipment, weighing over 1,600 tons, capable of generating up to 74,725 horsepower, and is described as the most powerful high-pressure natural gas dual-fuel engine currently manufactured in China.
What is the 8G95 marine engine and why is this delivery a milestone
The delivered engine is the 8G95ME-C10.5-GI-EcoEGR model. In practice, it represents a turning point because it consolidates Chinese national production in large-bore, high-quality marine engines, a segment considered critical for the shipbuilding industry.

Scientists have discovered that the sparse beard in many indigenous people may be linked to a 30,000-year-old genetic mutation, inherited from Asian ancestors and preserved in American peoples as a living mark of human evolution.
The fact that it is dual-fuel and operates with high-pressure liquefied natural gas places the model in a strategic category for large vessels, precisely those that concentrate cargo volume and require robust solutions for continuous operation.
The numbers that explain the “industrial scale” of the 8G95
The engine data helps visualize the project’s dimension:
- Height: 16 meters
- Weight: over 1,600 tons
- Maximum power: up to 74,725 horsepower
- Application: ultra-large container ships of 21,000 and 24,000 TEUs
- Type: LNG dual-fuel, with high-pressure natural gas
These numbers position the marine engine as a central component for ships operating on long routes and requiring high power to maintain performance even with maximum load.
How EGR allows compliance with IMO without external devices
One of the most relevant aspects of the model is the exhaust gas recirculation (EGR) system. According to the base, this feature allows the engine to comply with International Maritime Organization (IMO) emission standards without the need for external emission reduction devices.
In practice, this means that the marine engine comes with an integrated package to meet environmental requirements, without relying on additional equipment installed outside the engine to control emissions.
What changes in practice: safety, efficiency, and fewer emissions in operation
The developers stated that the model offers advantages in safety, reliability, energy efficiency, and lower emissions. The combination of dual fuel with exhaust gas control is presented as a way to maintain performance in giant ships while simultaneously reducing environmental impact.
This type of solution gains importance because ultra-large container ships account for a huge part of maritime trade and operate with intense energy demands, which makes any gain in efficiency and emissions a practical differentiator.
The technical challenges the team had to overcome to achieve the ready engine
The development of the 8G95 involved engineering obstacles that were described as decisive for the project’s success. The team overcame challenges such as:
- Direct injection of high-pressure natural gas into the cylinders
- High-pressure exhaust gas recirculation
- Dynamic cylinder control
These points indicate the complexity of the **marine engine** and explain why the delivery was treated as an important advance in the national production of large-bore engines.
Why this is gaining attention now: larger ships, more cargo, and tougher rules
The delivery in Dalian comes at a time when container ships continue to increase capacity and efficiency, while environmental standards are becoming more demanding. An engine of this class, with high power and integrated EGR, fits this dual pressure: scale and emissions.
With this, China marks a milestone by internally producing an LNG dual-fuel engine of this size, reinforcing its industrial capacity in a component considered key in the naval supply chain.
In your opinion, are LNG dual-fuel engines like this 8G95 the most realistic “middle ground” for reducing emissions in maritime transport, or will the industry need to make an even bigger leap in the coming years?
