Last Amended: 2024-02-01
Terms used in these Standards are defined as follows: 1. Engine family: The diesel and alternative clean fuel engine (hereinafter referred to as diesel engine) with similar combustion cycle (strokes), cooling mechanism (e.g., air cooled, liquid cooled), cylinder block configuration, number of cylinders; location of air intake valves, air supply method (with or without turbo charge), emission control system, fuel supply system and intake air cooling methods (e.g., after cooler, inter cooler) are deemed as the identical engine family. 2. Vehicle configuration means light-duty diesel commercial or passenger vehicles that are identical in terms of the basic engine, emission control system, transmission and inertia weight class, and are deemed identical vehicle configuration. 3. In-use diesel and alternative clean fuel engine vehicle (hereinafter referred to as “in-use foreign diesel vehicle”) from abroad: the diesel vehicle which has been registered and licensed by the motor vehicle supervisory agencies of the country of importation, and an import and commodity tax payment (exemption) certificate issued by Customs must be obtained at the time of importation of such vehicle as documentary proof. 4. 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 occur. 5. Hybrid Electric Vehicle (hereinafter referred to as HEV): A vehicle which has an internal combustion engine and electric motor dual power sources and uses diesel or other alternative clean fuels. 6. Deterioration factors: Each engine family shall have separate emissions deterioration factors to present the durability performance of the specified vehicle or engine in real world operation if the user has conducted normal maintenance according to the owner’s manual provided by the manufacturer. The gaseous pollutant’s or particulate matter’s test results shall be multiplied or added by the applicable deterioration factors to represent the durability test results. 7. Ki factors: Ratio of non-regenerating driving cycle test results to regenerating driving cycle test results for vehicles with a periodically regenerating system. 8. Evolution coefficient: The exhaust emission ratio between the vehicle reaching its expected stable condition and before it is in use. 9. Defeat devices: Which, by measuring, sensing or affecting the vehicle’s operating parameters (such as speed, engine rpm, transmission gear position, temperature, altitude, intake manifold vacuum, or other parameters), may trigger, adjust, delay or stop the working or emissions control functionality of some part when the vehicle is in normal operating condition and hence reduce the effect posed to, or render no effect on, the emissions control. 10. Inspection organization: An organization (institution) or school that has been designated by the central competent authority to issue the inspection report for a diesel and alternative clean fuel engine vehicle (hereinafter referred to as the diesel vehicle) emission Certificate of Conformity (hereinafter referred to as the Certificate of Conformity) or heavy-duty diesel vehicle Letter of Conformity (hereinafter referred to the Letter of Conformity). 11. PEMS test family: A specific diesel 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).
