環境部｜v1.0
Last Amended: 2024-01-26
Terms used in these Standards are defined as follows: 1. Motorcycle model composition patterns (hereinafter referred to as Motorcycle configuration): Refers to when the power system of the motorcycle (such as internal combustion engine or hybrid power system with an electric motor, etc.), basic engine, fuel supply system, emission control system, transmission, and inertial mass are the same, then they are of the same model. 2. Engine family: Motorcycles have similar power system, combustion cycle (number of strokes), type of cooling system (air, seawater), cylinder block structure (i.e. parallel, V-type, opposite type, cylinder aperture center spacing distance, etc.), number of cylinders, air supply method, fuel supply (method, numbers and measuring systems, etc.), evaporated gas storage device, catalytic converters (oxidation catalyst, reduction catalyst or three-way catalytic), secondary air system, electronic control module vehicle can be summarized as the same engine family. 3. In-use motorcycles from overseas: Motorcycles 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 documentary proof. 4. On Board Diagnostics System (hereinafter referred to as OBD): A computer system inside the motorcycles that monitors motorcycle emissions control equipment and can diagnose current operating status, detect and save malfunction codes, and display the signal indicator if malfunctions occur. 5. Hybrid motorcycle: Refers to motorcycles with both internal combustion engines and electric motor-generator system. 6. Idle-stop or stop-start devices: Devices which while a moving motorcycle temporarily stops for traffic lights, etc., may maintain the motorcycle in an idle state for a while and then have the engine enter the off-state automatically, but can re-start the engine once the throttle is opened. 7. Defeat devices: Devices which, by measuring, sensing or affecting the motorcycle’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 operation or emissions control functionality of some part when the motorcycle is in normal operating condition and hence reduce the effect posed to, or render no effect on, the emissions control. 8. Inspection organization: An organization (institution) or school that has been designated by the central competent authority to issue the inspection report for a motorcycle configuration’s emission Certificate of Conformity (hereinafter referred to as a Certificate of Conformity). 9. Evolution coefficient: The exhaust emission ratios between the motorcycle reaching its expected stable condition and before the motorcycle is in use.
