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

Vehicle Testing — Selection

Vehicles selected for vehicle testing shall be representative of the said engine family; the principles of selecting test vehicles are as follows:

1. From the said engine family, the vehicle models expected to have the greatest quantity of pollutant emissions shall be selected for waste emissions testing. Of the vehicles selected, the vehicle with the greatest loaded vehicle weight shall be selected. When different vehicle models have an identical load weight, the vehicle model with the greatest road resistance (at 80 kph) using dynamometer testing data shall be selected. If road resistance is identical, the engine emitting the greatest volume of exhaust shall be selected for testing. If the quantity of exhaust is identical, the vehicle with the greatest total gear ratio for all gears (including the overdrive device) shall be selected; in the case of identical gear ratios, the greatest axle ratio shall apply.

   If the vehicle models in an engine family adhering to EU emission standards span over different classes of emission standards, Class-1 shall be taken as the standard.

2. If the central competent authority does not consider the test vehicle selected by the applicant to be representative of the said engine family, the central competent authority shall designate another vehicle model in the said engine family as the test vehicle.

3. From the said engine family, select one vehicle of the vehicle model expected to have the highest evaporative emission value. If unable to ascertain the vehicle model expected to have the highest evaporative emission value, select one vehicle from any of the vehicle models in the engine family.

4. All test vehicles selected for the testing application shall be finished products for normal use.

5. Vehicles in the same engine family that were manufactured in, or imported from, different countries shall be selected separately for testing.

   1. This testing shall be conducted according to Gasoline Vehicle Waste Emissions Testing Methods and Procedures and Gasoline Vehicle Evaporative Emission Testing Procedures.

   2. Testing for vehicles adhering to EU emissions standards shall be conducted pursuant to EU Directive 98/69/EC and relevant directives pertaining to types Ⅰ, Ⅱ, and Ⅴ and the testing regulations of Annex Ⅺ.

2. When more than one test is conducted on the same test vehicle, the test scores from the final test shall be taken as the emission test results.

3. The deterioration factor of the said engine family shall be multiplied or added to the scores from new vehicle testing, including new vehicle model certification, quality control testing, and random new vehicle testing. The multiplied or added value shall be the basis for determining whether or not the engine family complies with emissions standards. Before comparing with the emissions standards, the test values shall be calculated to one decimal place after that of the emission standard and then rounded. The evaporative emission test score shall be rounded to the first decimal place. The rounded value shall not exceed the emissions standard.

4. The applicant shall determine the minimum mileage needed to attain stability in emissions testing. However, the accumulated driving mileage for new vehicle waste emissions testing shall at most be fine-tuned to 6,400 kilometers.

6. Other air pollution control equipment or related systems or components — When a malfunction or deterioration occurs in any power system or component related to air pollution control, the OBD must diagnose the malfunction status before the resulting condition causes NMHC, CO, or NO_x pollutant emissions in excess of the OBD control threshold value. The OBD must also diagnose the malfunction status of a malfunction or deterioration that affects waste emissions but is not listed in Paragraph 3, Subparagraphs 2 through 5. This item shall include exhaust gas recirculation (EGR) system, secondary air system, fuel control system, etc.

7. Other components related to air pollution control — When a malfunction or deterioration occurs in sensors, actuators or components with electronic signal input/output that affect pollutant emissions but are not listed in Paragraph 3, Subparagraphs 2 through 5 of this Appendix, the OBD shall diagnose the malfunction status. This portion shall monitor the continuity and rationality of electronic circuits. The actuator for computer system control shall be able to accurately perform the actuation of computer commands.

An MIL shall be installed on the dashboard facing the driver’s seat; the indicator light shall comply with the following regulations:

1. The MIL must have sufficient brightness, but red or orange light may not be used, and it must be installed in a place that is clearly visible to the driver. Before engine startup the MIL shall light up when the key is placed to the On position, and display checkup functions such as engine inspection and engine maintenance. MIL messages shall be expressed as Check Engine, Service Engine Soon; as engine symbols that comply with ISO 2575, or as words or symbols approved by the central competent authority. Only one MIL may be installed in a single vehicle; however, other special purpose warning lights (for the brake system, seat belts, fuel tank, etc.) are not subject to this restriction.

2. After the OBD diagnoses and confirms a malfunction, the MIL must remain lighted. When the engine misfires or causes damage to the catalytic converter, the MIL must flash once per second. Should the occurrence of this type of misfire be diagnosed again during the driving cycle (the process for which at minimum shall include the engine startup and engine shutdown) or if a similar condition should occur during the following driving cycle, the MIL must remain lighted continuously.

3. The MIL shall light up when the key is placed to the On position; if no malfunction is detected the MIL shall turn off after the engine is running. In the case where the fuel system or engine misfire have been diagnosed previously, if in the following three consecutive driving cycles under similar conditions the MIL detects no new malfunctions, the indicator light shall be turned off. Similar conditions means the engine speed differential is within 375rpm, engine load differential is 20%, and the engine warm-up conditions are identical to those of the engine misfire that was initially detected.

4. After malfunctions other than the fuel system and engine misfire are detected, if no malfunctions similar to the said malfunction code are not detected in the following three consecutive driving cycles, the MIL light may be turned off. With the consent of the central competent authority, the applicant may use statistical data from other MIL protocols.

Computer coding for OBD memory and scanning shall comply with the following regulations:

1. The OBD must record all diagnosed malfunction codes; readiness codes for the air pollution control equipment and related components; and pollution control system status codes and save these codes in the OBD computer memory. The said computer codes must be able to be read via a standardized connector.

2. The OBD must save any and all malfunction codes for malfunctions that have been detected, confirmed, and then followed by a flashing indicator light. The malfunction code shall be configured in a way that allows each individual equipment unit, system or component that has malfunctioned to be identified separately. The light indicator status of the MIL shall be displayed after each individual computer code is saved.

3. For a misfire in a single cylinder, the malfunction code shall be configured in a way as to allow for the said cylinder to be identified, unless the applicant can provide data or an analysis that sufficiently proves the impossibility of accurately identifying which cylinder has misfired within a certain specified operating range. For a multi-cylinder misfire, the malfunction code must be configured in a way as to identify the malfunction as multi-cylinder. When the saved malfunction code is a multi-cylinder misfire, there is no need to configure the code in order to identify each cylinder that has misfired.

4. When the same malfunction code is not diagnosed for at least another 40 engine warm-up cycles, the diagnosis system may erase the said malfunction code and turn off the indicator light.

5. Individual status codes or readiness codes must be saved in the computer so as to judge whether or not the pollution control system functions are normal. These pollution control system functions must be monitored while operating in the driving cycle to complete an appropriate diagnostic analysis.

6. For those items that require continuous monitoring (such as engine misfire monitoring, fuel system monitoring, etc.) there is no need to save a readiness code. If abnormal operating conditions occur continuously during testing (such as an atmospheric temperature lower than 4.5℃ and/or at a location more than 2,438 meters above sea level), prompting the temporary suspension of monitoring for several driving cycles, the OBD may temporarily suspend the configuration and storage of relevant computer codes.

OBD storage and reading of diagnostic data shall comply with the following regulations:

1. The first time a malfunction is detected in a component or system, a freeze-frame of the engine status data at the time of the malfunction must be saved in the OBD computer memory. If a misfire or fuel system malfunction occurs thereafter, the previously saved engine status data shall be replaced with that of the engine shutdown or fuel system malfunction, whichever occurs first. The engine status data to be saved shall include the engine rotation speed, open and closed loop operations, fuel system control, cooling water temperature, calculated load weight, fuel pressure, vehicle speed, airflow rate, and air intake pressure.

2. The applicant shall select a set of effective freeze-frame data and offer this data for the servicing of future vehicles. After the malfunctioning component or system has been serviced and repaired, and the malfunction code is in compliance with all memory storage regulations, the said malfunction code may be erased.

3. Except for freeze-frame data, all other detection data may be captured through a standardized port. The aforesaid detection data includes the engine water-cooling temperature; fuel control system mode (open loop, closed loop or other mode); fuel trim; advance ignition timing; intake air temperature; air intake pressure; airflow rate; engine rotation speed; air control valve sensor output value; secondary air status; calculated load value; vehicle speed; and fuel pressure. These signals must be regulated pursuant to the standards of the Society of Automotive Engineers (herein referred to as SAE) or the International Organization for Standardization (herein referred to as ISO) and it must be apparent from the actual signal that they are default or limp-home mode.

The standardized interface for the OBD shall comply with the following regulations:

1. The communications protocol for OBD software shall comply with the SAE J1850 standard. The communications protocol standards ISO 9141-2, ISO 14230-4, and ISO 15765-4 may be used as a substitute.

2. The standard for OBD basic diagnostic data shall be SAE J1979 or ISO/DIS 15031-5.

3. The standard for OBD malfunction codes shall be SAE J2012 or ISO/DIS 15031-6.

Applicants for engine family vehicle compliance verification that are temporarily unable to comply with all OBD regulations will be handled according to the following principles:

1. After technical feasibility and the vehicle’s lead-time and replacement window during the mass production phase are taken into account, or when a computer program upgrade or other extenuating circumstance causes the OBD monitoring functions to become unreliable, the applicant must submit an application allowing for temporary non-compliance with OBD standards. Once the application is approved by the central competent authority, the applicant’s OBD can temporarily remain in partial non-compliance with OBD standards.

2. Insufficient monitoring shall not occur in primary OBD monitoring items such as catalytic converter, oxygen sensor, misfire, gasoline vapor control system, and EGR.

3. An applicant applying for temporary partial non-compliance with OBD standards shall apply for compliance verification the year after the engine family year when OBD improvement measures are implemented in order to ensure engine family compliance with all OBD standards. If, due to factors such as software modifications or additional lead time the applicant is unable to complete improvements in the vehicle model year, the applicant shall apply for the continued use of the OBD standards temporary partial non-compliance permit and append all relevant documents. Upon approval by the central competent authority the permit may be used until the following vehicle model year. Continued use shall not exceed three consecutive vehicle model years.

4. For an engine family applicant that is holding US or EU compliance verification and has acquired Taiwan compliance verification, if the applicant has already completed improvements for OBD standards temporary partial non-compliance, the applicant may not re-apply for OBD standards temporary partial non-compliance for the said engine family.

5. In the case of clean alternative fuel engine vehicles (such as natural gas fuel vehicles, liquefied petroleum gas vehicles, methanol fuel vehicles, and ethanol fuel vehicles), when there is a possibility that the use of clean alternative fuels may reduce the reliability of OBD monitoring functions, the applicant may ask the central competent authority for an exemption from the specified monitoring standard requirements. However, clean alternative fuel vehicles must still be equipped with an OBD and comply with OBD standards.

   8. If any adjustable variables have already been set in the compliance verification application or user’s manual tolerance range, these variables may not be reset.

4. Without examination and approval from the central competent authority, vehicles for random testing shall not be adjusted, maintained or tested by the applicant.

5. Special equipment required for testing shall be prepared by the applicant. Applicants may not use the inability to provide necessary equipment as an excuse for test invalidation.

6. Applicants whom have any objections or are unable to undergo testing should provide the central competent authority with an explanation prior to the test. The central competent authority may authorize adjustments and repairs to the vehicle which is to be tested in order to ensure a reasonable testing environment. Should the central competent authority deem a vehicle taken for random testing not an appropriate representative, the central competent authority may revoke the credentials of that vehicle from the sample quantity and choose another vehicle for replacement. The number of replacements is decided by the central competent authority.

Determining and handling of testing results

1. All vehicles that have undergone random testing and have been confirmed to comply with emissions standards shall be considered to be in compliance.

2. If a sample test vehicle is deemed non-compliant, the applicant may request another test, or may directly request determination of the preliminary test to be non-compliant.

   1. Requests for repeat testing may only be made prior to removal of the vehicle from the testing facility.

   2. No repairs, modifications or tests may be performed during the repeat test period.

   3. Results of the repeat test shall be considered final, and all vehicles found to be in compliance with emissions standards shall be considered in compliance.

3. When the preliminary determination is non-compliance, and if none of the vehicle exhaust pollutant emission values exceeds 50% of the emissions standards, the applicant may, within 15 days from the day of receipt of notification from the central competent authority, submit a written request for repeat testing to the central competent authority, or may accept the determination of new vehicle non-compliance and request rectification procedures for non-compliant vehicles from the central competent authority.

   1. The number of samples submitted for repeat testing may be determined by the Applicant, however, they may not be less than twice the number of test samples found to be non-compliant in the initial test.

   2. When choosing, preparing, adjusting and testing, vehicles must be identical to those from the preliminary test.

   3. For vehicles found in non-compliance during the repeat test, applicants may request one additional repeat test prior to removal of the vehicle from the testing facility. The results of the additional repeat test shall be considered final, and no repairs, modifications or tests may be conducted during the additional repeat test.

   4. If the average air pollutant values for vehicles determined non-compliant in initial testing and all repeat test vehicles are below emissions standards, and if none of the vehicles’ pollutant emissions values exceeds 50% of the emissions standards, the test samples shall be considered in compliance; otherwise, the test samples shall be considered non-compliant.

      For OBD testing pertaining to the foregoing paragraph, if the sum of the number of vehicles determined non-compliant in initial testing and the number of repeat test vehicles that failed testing divided by the sum of the number of vehicles determined non-compliant in initial testing and the number of all repeat test vehicles is less than 0.4, and the sum of the number of vehicles determined non-compliant in initial testing and the number of repeat test vehicles that failed testing is less than 4, the test samples shall be determined as in compliance. The methods of determination are as follows:

      Method 1→ $\frac{\mathrm{no.\; of\; vehicles\; determined\; non-compliant\; in\; initial\; testing}+\mathrm{no.\; of\; repeat\; test\; vehicles\; that\; failed\; testing}}{\mathrm{no.\; of\; vehicles\; determined\; non-compliant\; in\; initial\; testing}+\mathrm{no.\; of\; all\; repeat\; test\; vehicles}}< 0.4$^{[Formula description]}
      Method 2→ $\mathrm{no.\; of\; vehicles\; determined\; non-compliant\; in\; initial\; testing}+\mathrm{no.\; of\; repeat\; test\; vehicles\; that\; failed\; testing}< 4$^{[Formula description]}

   5. If vehicles have been determined compliant, but initial test or repeat test results returned non-compliance, the reasons for non-compliance and rectification measures must still be explained. Additionally, test results showing compliance for each vehicle after rectification should be submitted to the central competent authority for reference.

4. When new vehicle random testing shows an engine family to be non-compliant and the central competent authority cancels compliance verification, the applicant shall, within 30 days of the day of receipt of notification, submit a recall and correction plan for all unsold and sold vehicles of the said engine family.

   Once the central competent authority has reviewed and approved the plan, the applicant shall, within 90 days of the day the approval letter is delivered, complete the recall and corrections. Those that fail to complete corrections by the deadline shall, within 30 days of the day of receipt of the approval letter, submit a specific improvement plan and apply for an extension with the central competent authority. The central competent authority shall approve the improvement deadline based on actual conditions, and the maximum extension may not exceed one year. The central competent authority may immediately terminate the improvement deadline of those who, after examination and confirmation, demonstrate the failure to strictly carry out implementation in accordance with the improvement plan.
