Core Viewpoint - The article highlights the rampant malpractice in vehicle emission testing in China, where some inspection stations are allowing non-compliant vehicles to pass while failing compliant ones, often for illegal profit [2][18]. Group 1: Emission Testing Malpractices - A significant number of vehicle inspection stations are engaging in fraudulent practices, including using OBD (On-Board Diagnostics) cheating devices to generate false data, allowing non-compliant vehicles to pass inspections [9][12]. - In a specific case in Shenyang, 13,000 identical OBD codes were detected, indicating the use of a cheating device that replaced actual vehicle data with fabricated information [5][9]. - The use of OBD cheating devices has led to the emergence of a gray market, where these devices are sold online, contributing to widespread corruption in the vehicle inspection industry [9][11]. Group 2: Regulatory Response and Industry Impact - In response to the growing issue, the Ministry of Ecology and Environment has initiated a nationwide crackdown on fraudulent vehicle emission testing, resulting in the revocation of testing qualifications for 580 inspection agencies and criminal charges against 110 entities by December 2024 [18][20]. - The article emphasizes the importance of vehicle emission testing in reducing air pollution, noting that nitrogen oxides from vehicles account for over 34% of national emissions, with heavy-duty trucks contributing 80% of that figure [20]. - New regulations are being proposed to enhance the functionality of OBD systems to prevent tampering and ensure compliance, aiming to restore integrity in the vehicle inspection process [20].
