FAQ
About CFR octane and cetane engine service
Short answers to common customer questions, written for clear citation.
What does Guangzhou Zhen’an do?
Guangzhou Zhen’an Technology Development Co., Ltd., based in Guangzhou, China, provides inspection, repair, used equipment support, laboratory relocation, parts and reference-fuel related service for CFR F1/F2 gasoline octane engines and F5 diesel cetane engines, mainly for refinery labs, quality centers and third-party testing labs.
How is inspection different from repair?
Inspection focuses on preventive checks and calibration review—temperatures, compression-ratio backlash, fuel system and instrument zero. Repair covers troubleshooting and overhaul such as top-end work, four-bowl carburetor, crankcase, and on F5 the cylinder head, injection handwheel and injector. Scope is set from on-site measurements.
Is this an OEM-authorized site?
No. We are an independent third-party service shop with no affiliation or authorization from CFR Engines Inc. or Waukesha. Work is performed under the customer’s inspection, repair or relocation contract; warranty terms follow that contract.
What does machine relocation include?
Relocation typically covers marking, transport, leveling, reconnecting cooling water and exhaust, power checks, and re-testing with reference fuels. Leveling and back-pressure are often underestimated compared with lifting.
How are reference fuels supplied?
The fuels page lists octane and cetane reference materials from brands such as NIM China, Chevron and American Hydrocarbons. Call for additional products or custom needs.
