The most important effect of the implementation of the Euro III standard on the automotive industry is to force auto companies to upgrade key technologies such as engines. This will greatly promote the qualitative leap in the domestic automotive industry's technological level. Some automotive technologies that have fallen behind or even eliminated in foreign countries will be kept out of the domestic automobile market, and the interests of consumers will be further protected.
According to experts from the Pollution Control Department of the National Environmental Protection Agency, an iconic difference between the Euro III and Euro II standards is the installation of an OBD vehicle diagnostic system. This system will monitor the car's exhaust gas emissions at any time from its operating condition. Once it exceeds the limit, it will immediately issue a warning.
It is understood that in fact, some of the models introduced by the domestic joint-venture automobile factory in the past were originally equipped with OBD, and reached the Euro III or even Euro IV standard, but they are often subtracted from domestic ones. This is done on the one hand to save costs, and on the other to avoid other problems caused by OBD alarms when the oil quality is not up to standard.
A related person in a domestic joint venture stated that the upgrade of the engine from Euro II to Euro III is not an easy task. It requires a continuously variable valve technology with a high technological content and requires a variety of configurations, and all of this Need a lot of expenses to support. To meet the new emission standards, companies need to improve or add a three-way catalytic converter, and then adjust the engine. The upgrade of this technology requires a certain amount of money.
