Diesel Engine IV emissions will be delayed until 2015


It has postponed the implementation time of the four diesel engines for the two countries and will be postponed again for one and a half years!

In the forthcoming implementation date of the National Fourth Plan, July 1, 2013, some vehicle manufacturers were notified that it was difficult to provide the full-scale national-four diesel emissions nationwide and it was difficult to supply urea for reprocessing. Satisfaction, therefore, the relevant national ministries and commissions will implement the four stages of diesel emissions from January 1, 2015. At the same time, starting from July 1 this year, the National III emissions model will no longer allow the announcement of the Ministry of Industry and Information Technology.

This is already the third time to postpone the implementation of diesel IV emissions. As early as December 21, 2010, the Ministry of Environmental Protection had for the first time postponed the implementation of the four standards for diesel vehicles. The Ministry of Environmental Protection said at the time that for vehicles with compression ignition engines and automobiles, the implementation of the Fourth National Standard was tentatively postponed for one year, and the National IV emissions originally scheduled for January 1, 2011 were postponed until January 1, 2012. Afterwards, by the end of 2011, the relevant ministries announced that diesel engine country 4 has been postponed again by one and a half years, starting from July 1, 2013.


At the end of last year, at the beginning of this year, severe haziness was encountered in Beijing and other places. Coupled with the fact that the country’s emissions had already been postponed twice, and faced with the central government's determination to deal with environmental pollution, the public generally speculated that the diesel engine’s National IV emissions would not be postponed. However, the "two barrels of oil" has always stated that it is not possible to provide the country's fourth-ranked diesel on a nationwide basis on time, and that the supply of urea is also difficult to meet. Eventually diesel emission upgrades are delayed for the third time and delayed for a year and a half. Three cumulative delays totaled 4 years.

However, the above news was received by the entire vehicle company. It has not yet been officially released to the public in an official form.

Although the country has been postponed for a year and a half, some cities have separately introduced local emission policies. For example, Shanghai and Chengdu announced the timing of the implementation of the National IV emissions: Shanghai will no longer be able to sell the three diesel vehicles from July 1 this year. Vehicles that were previously purchased but not on the cards can be sold before August 1st at the latest.

As the country's emission time changed several times, many engines and vehicle companies spent a lot of resources for this, matching the National IV engine with the entire vehicle and making announcements. Regardless of where the responsibility for postponing emissions is, where the implementation time is repeatedly announced, and where delays are announced before implementation, there has been a massive waste of resources.
