Full Disclosure of the Counterfeit Engine Case
Case Overview
Russian company ACM Resxxxxx LLC, a long term operator in the Russian machinery market, purchased a CHEXXX T 40 bulldozer with a contractual commitment to equip a CCEC manufactured QSK19-C series engine.

Key Facts of the Fraud
1. Nameplate Reveals the Truth
The engine nameplate clearly shows Manufactured by Chongqing San Chai Engine Company, not Chongqing Cummins. The engine serial number is 56192105, model QSK19, with manufacturing date August 18, 2023, and production order number 41868.

2. Forged Documents Attempt to Deceive
When ACM Resxxxxx questioned CHEXXX, the latter provided two sets of so called “CCEC official documents” to prove the engine was genuine:
• An “Engine Test Report” claiming to be issued by CCEC
• A “Certificate of Origin” claiming to confirm CCEC manufacturing

• A “Certificate of Origin” claiming to confirm CCEC manufacturing
3. Blatant Forgery Flaws Fully Exposed
These documents are crude fakes with obvious errors:
• The test report misspells ENGINE TEST DATA LOG as ENGINE TEST DATA L0G, replacing the letter O with the number 0, a low level mistake impossible for formal CCEC documents.
• The report lacks valid signatures, official seals, or legal certification from CCEC.
• The Certificate of Origin was issued by Chongqing xxxxonder Trading Co., Ltd., which has no connection with CCEC and no right to issue CCEC origin certificates.
• All documents are self fabricated by non authorized parties and have no legal validity or connection with Chongqing Cummins.

Conclusion: Typical Counterfeit Fraud
The engine with serial number 56192105 is not a Chongqing Cummins product. It is a Chongqing San Chai engine equipped with forged documents pretending to be CCEC QSK19-C. This is a typical case of using counterfeit and shoddy products to impersonate genuine branded engines.
Severe Consequences of Counterfeit Engines
This fraud has caused multi level harm:
- Direct economic losses for the end user, including equipment downtime, maintenance costs, and project delays.
- Irreversible damage to CHEXXX’s brand reputation, which took years to build.
- ACM Resxxxxx LLC has filed a lawsuit against CHEXXX in a local court, leading to legal risks and commercial disputes.
- Counterfeit engines disrupt the global supply chain, damage the image of legitimate Chinese manufacturing, and threaten the trust of international buyers.
Critical Industry Warning: Do Not Sacrifice Quality for Low Price
SinoMac solemnly reminds global equipment manufacturers, traders, and buyers:
When purchasing engines from China, never select suppliers based solely on price.
Low price traps often hide:
- Counterfeit cores and unqualified assembly
- Forged test reports and fake certificates
- No official warranty or after sales service
- Untraceable production history and legal risks
Genuine engines provide:
- Stable performance and long service life
- Complete formal documents and full traceability
- Official warranty and global after sales support
- Protection of your brand value and business reputation
Choose quality first, then negotiate price. This is the only way to achieve sustainable business.
