Cummins ISG has successfully obtained the US Patent Office's "Internal Combustion Engine Wet Cylinder Liner Patent" certificate

Recently, Steven M Chapman, Vice President of Cummins Group, officially received the "Internal Combustion Engine Wet Cylinder Liner Patent" (No. 8978620) certificate from the United States Patent and Trademark Office. This patent was jointly obtained by Cao Side and the Cummins ISG engine development team. Cao Side is currently the Vice President of the Group responsible for China and Russia business, leading the development of multiple innovative technologies. This patent reflects Cummins' innovation not only reflected in the engineering team, but also the "craftsman spirit" pursued by the entire company from top to bottom.

Steven M Chapman, Vice President of Cummins Group

Innovation has always been the main theme in the nearly century long history of Cummins Corporation. Cummins has always been committed to research and development investment, with annual R&D investment exceeding $700 million for many consecutive years. Cummins is the most innovative company in the field of diesel engines, with over 1500 valid patents. This makes Cummins a world leading engine design and manufacturer, continuously driving technological innovation across the industry.

The acquisition of this patent is inseparable from the joint efforts of Cummins R&D team. At present, the patent has been successfully applied to Cummins' latest ISG heavy-duty engine platform.

Cummins ISG Heavy Engine Platform

The G in ISG, symbolizing "revolution" in Chinese, demonstrates its technological innovation. This model takes customer needs as input and drives engine design. More than 100 R&D personnel from countries such as China, the United States, Europe, India, and Mexico have worked together for 5 years of development, over 60000 hours of bench testing, and over 6 million kilometers of actual road testing. Once launched, it gained market recognition and became a new generation of Cummins classic engines.

At present, the ISG engine combines multiple Cummins patents and 29 key component patent technologies, making it the true "king of patents" for engines. Below, we will introduce several main core patented technologies of ISG:

Innovative patented technology for wet cylinder liners

This is the patent obtained by the Vice President of Cummins Group, as mentioned earlier. The replaceable wet cylinder liner effectively improves the reliability of the engine and reduces maintenance frequency. The lightest in weight and compact in appearance, significantly improving load-bearing capacity and transportation efficiency. The modular integrated design significantly reduces the frequency of faults and achieves excellent reliability.

Simplified and efficient whole machine patent design

ISG adopts a leading modular design concept, which reduces the number of parts by nearly 50% compared to traditional diesel engines, improves reliability, and facilitates maintenance. The reduction in the number of parts improves the reliability of the product while saving 50% of maintenance time. 792 kilograms of self weight, compared to other competitors, reduces self weight by 30%, but can achieve 490 horsepower power output, and the ISG engine creates the highest specific power. Customers can take it lightly
