Regulations Governing Issuance, Revocation, and Cancellation of Compliance Certification for Gasoline and Alternative Clean Fuel Engine Vehicle Emissions Inspections Article 2

Terms used in these provisions are defined as follows:2.1 For gasoline and clean alternative fuel engine vehicles (hereinafter referred to as the “gasoline vehicles”), vehicle configuration means automobiles that are identical in terms of the basic engine, exhaust system, transmission and inertia weight class, and are considered as the same vehicle model.2.2 Engine family: Vehicles with identical configurations in terms of combustion cycle (engine stroke); engine cooling mechanism (e.g., air cooled, liquid cooled); cylinder block configuration; number of cylinders; location of air intake valves; air supply method; fuel system type; catalytic converter type (oxidation catalyst, reduction catalyst or three-way catalyst); number of catalytic converters and their cubic measurement (variation of 15% or less in the actual reaction surface area) and composition; and electronic control modules are considered as the same engine family.2.3 In-use vehicles from overseas: Vehicles registered and licensed by the motor vehicle supervisory agencies of the country of importation must obtain an import and commodity tax payment (exemption) certificate issued by Customs at the time of importation as a documentary proof.2.4 Effective operation: normal operation of the vehicle’s emissions control equipment originally designed by the manufacturer.2.5 On Board Diagnostics System (hereinafter referred to as OBD): A computer system inside the vehicle that monitors vehicle emissions control equipment and can diagnose current operating status, detect and save malfunction codes, and display the signal indicator if malfunctions occurred.2.6 Hybrid Electric Vehicle (hereinafter referred to as HEV): A vehicle that has both internal combustion engine and electric motor dual power sources and its engine uses gasoline or other alternative clean fuels.2.7 Evaporative family: Vehicles with a fuel supply system that are based on the same principle or method (such as single-point fuel injection), with the same fuel vapor storage and purge devices, fuel measurement system, fuel vapor separator, fuel tank safety valve or other evaporative emission control devices, with similar shape, material, cross section, length, or capacity volume tanks, fuel and tubes and other fuel system devices may be categorized as the same Evaporative Family.2.8 Evolution coefficient: The exhaust emission ratio between the vehicle reaching its expected stable condition and before it is in use.2.9 Defeat devices: Through the measured or sensed vehicle’s operating parameters (such as: vehicle speed, engine rpm, transmission gear position, temperature, altitude, intake manifold vacuum, or other parameters) to trigger, adjust, delay or stop the emissions control functionality of certain devices when the vehicle is in normal operating conditions and hence reduce or with no effect on the emissions control.2.10 Inspection organization: An organization (institution) or school that has been designated by the central competent authority to issue the inspection report for a gasoline vehicle model’s emission Certificate of Conformity (hereinafter referred to as a Certificate of Conformity).2.11 On-board test family (PEMS test family): A specific vehicle model that is designed with similar exhaust and emission characteristics; or that can be classified as the same on-board test family according to the PEMS test family classification principles stipulated in No. 715/2007 and the subsequent directives established by the European Union (hereunder briefed as the EU).2.12 Regeneration factors (Ki factors): The pollution variation ratio observed during the equipment regeneration process for the vehicles being provided with the cyclic regenerative equipment.
