First, through surveying and collecting of international vehicle CO2 emissions data and analyze the emission factors to comprehend the current status of domestic CO2 emissions from vehicles, global technology level on CO2 reduction, and to establish an information inquiry platform for the Public. This project also surveyed current domestic and abroad CO2 control strategies with consideration of domestic conditions to propose initial preparation tasks for CO2 emissions control from heavy duty vehicles; this project also aggregated future viable control strategies for emissions from vehicles in Taiwan.
To avoid inconsistent test results caused by implementing dual available test procedures after the stage 5 emission standards enter into force, a conversion factor is proposed for these two different procedures’ test results to avoid additional test cost burden for manufacturers. Twenty stage 5 compliance vehicles were selected to perform both the EU and the US test procedures to study the conversion factor for these two procedures’ test results. The study showed that the conversion factor will not be varied by different vehicle type (passenger car and light duty truck), different engine displacements, whether engine is equipped with GDI or not, and in the end a single conversion factor was proposed for these two test procedures. Consider the increasing number of Hybrid Electric Vehicles (HEV) being sold in Taiwan, 40 HEV were selected and performed emissions tests to establish domestic regulatory test laboratories’ inspection and test capability correspond to the US SAE J1711 and the EU ECE R101 test procedures and also to establish basic HEV emissions data in Taiwan.
Since the initial promotion of the “Voluntary Carbon Dioxide Emissions Reduction Agreement” in 2009, there are 13 manufacturers and importers already signed the agreements and 8 of them were projected to achieve their reduction targets in advance by the end of 2013. The effect of CO2 reduction from light duty passenger vehicles through voluntary agreements is significant, estimated 50,188 tons of CO2 emissions were reduced in 4 years.
Through holding 8 sessions of energy saving and carbon reduction training courses to introduce the concept of eco-driving and providing the latest energy saving trends and tips to improve the Public's driving habits. Meanwhile the Environmental Protection Administration and 6 local Environmental Protection Departments have co-signed agreements with enterprise and corporate representatives to perform eco-driving, leading by Public sector to reduce CO2 emissions from vehicles through eco-driving.
In recent years, regulations implemented in Taiwan were harmonized with international regulations step by step, and it is urgent to revise the training materials for mobile source emissions inspection personnel. Through revision and integration of training materials could save national resources and enhance the domestic inspectors’ expertise. Finally, through submit papers to international conferences and to be published on the topics of describing the implemented motorcycle emissions control strategies in Taiwan, our international visibility could be increased and also declare our determination to continuous promoting vehicle emissions control strategies.
