Recently, Haoyue Fully Automatic Gasoline Octane Rating Engine—independently developed by Shanghai Shenkai Petroleum & Chemical Equipment Co., Ltd. (hereinafter referred to as “Shenkai Equipment”), a wholly owned subsidiary of Shenkai—has successfully passed the acceptance testing of Sinopec Research Institute of Petroleum Processing (hereinafter referred to as “Sinopec RIPP”). In a direct comparison with CFR’s F1/F2 octane rating engines, on-site data results demonstrated full compliance with method standards, with highly stable measurements and convenient automated operation. This achievement signifies that Shenkai Instruments has successfully broken the long-standing import monopoly and realized domestic substitution of octane rating engines. With its solid technological capabilities earning authoritative recognition from Sinopec RIPP, this marks an important milestone in China’s independent development of core fuel-testing equipment.

| Deep Technical Expertise: Shenkai Equipment Breaks Through with Solid Capabilities

As the national institution responsible for formulating petroleum product standards, Sinopec RIPP imposes exceptionally stringent requirements on the precision and automation of testing instruments. For years, octane rating tests at RIPP as well as in most domestic research institutes and refining enterprises have relied heavily on U.S.-made CFR equipment, which presents challenges including low automation and high maintenance costs. To break the import monopoly, Shenkai Instruments has spent more than two decades cultivating deep industry expertise and insisting on independent innovation. With its outstanding performance, the Haoyue Fully Automatic Gasoline Octane Rating Engine successfully passed acceptance testing, marking a major breakthrough in domestically manufactured high-end testing equipment.

| Three Core Advantages of the Haoyue Fully Automatic Gasoline Octane Rating Engine

· Standards-driven quality and rigorous control: The equipment strictly adheres to both international and national standards, embedding quality-control principles throughout the entire R&D, manufacturing, and testing process. A full-chain quality-control system ensures the core commitment to precise measurement.

· Intelligent operation that overcomes operational complexity: The system features intuitive and user-friendly controls, with Shenkai’s proprietary automatic crankcase rotation system and one-click switching between Motor Method and Research Method. Combined with intelligent software, tests are completed fully automatically, removing the traditional barriers of complex operation and high learning curve associated with legacy instruments.

· Professional service for worry-free maintenance: The company has established a professional and comprehensive after-sales service system that provides technical support and maintenance throughout the entire lifecycle of the instrument. Its service scope covers not only its own devices but also maintenance solutions for imported octane and cetane engines. Key maintenance components have been domestically manufactured, resolving the long-standing industry pain points of imported devices being “too costly to repair” and “too slow to repair.”

Previously, two Shenkai CFR-A1 Gasoline Octane Rating Engines installed at Fushun RIPP were successfully put into service.After months of stable operation, they likewise earned user recognition for their reliability and ease of use, fully demonstrating Shenkai Instruments’ capability to support high-end research scenarios over the long term.

Since its launch, Shenkai Equipment’s octane rating engines have received extensive validation and recognition in both domestic and international markets. They have been widely adopted by CNPC, Sinopec’s key marketing subsidiaries, customs agencies, quality inspection institutions, and well-known third-party laboratories such as SGS, Saybolt, Intertek, Inspectorate, CTI, and CCIC. The products have also been successfully exported to Russia, South Korea, Singapore, Malaysia, and other countries, achieving dual expansion in domestic and overseas markets.

Shenkai Instruments firmly believes that as the technological sophistication of domestic equipment continues to advance, more industry users will choose and trust “Intelligent Manufacturing in China.” Looking ahead, Shenkai Instruments will continue to use technology as its pen and craftsmanship as its ink, writing new chapters in the development blueprint of domestic fuel-testing equipment. The company remains committed to contributing Shenkai’s strength to safeguarding national energy security and promoting high-quality development of the petrochemical industry.
