Accompanied by the accelerated progress of the dual-carbon goal, major vehicle manufacturers and OEMs in the field of commercial vehicles have actively responded to explore the path of sustainable development and increase the protection of the ecological environment.
Dongfeng Cummins has always been fully committed to exploring green development and practicing environmental protection, inheriting more than 100 years of global engine development experience from Cummins.
Cummins has been making efforts in energy-saving and environment-friendly production, green manufacturing technology, etc., and continues to launch new products with high efficiency, environmental protection and energy saving, and is committed to creating greater value for customers.
During the more than 20 years from National 1 to National 6 emission upgrading, Dongfeng Cummins has gone through many changes and upgrades in the emission technology route.
In 1996
Dongfeng Cummins started to implement Euro I standard engines at the very beginning of its establishment.
At that time, the emission standard of domestic engines was still unformed.
In 2000
Cummins was the first to introduce diesel engines meeting Euro II emission standards into the Chinese market.
Dongfeng Cummins synchronized its efforts to promote engine products with higher emission standards.
In 2002
Dongfeng Cummins formed the “Green Diesel Engine” promotion program
Through rolling technology introduction and self-development strategy
Continuously upgrading the technical level
Reduced engine emissions of pollutant gases
July 1, 2004
National II emission standard was implemented in China
Dongfeng Cummins passed the national certification in January 2004
April 2005
Dongfeng Cummins launched series of engines meeting Euro IV emission standard
Selective Catalytic Reduction (SCR) technology was adopted.
In 2006
Cummins has realized the batch matching of Euro IV vehicles in China.
Dongfeng Cummins ISBE150 30 engine was the first one to pass the verification of National III.
In 2008
Dongfeng Cummins passed the verification of the engine by German Rheinland Company in the engine laboratory of National Quality Inspection Center
Passed the Euro IV certification of ISDe electronically controlled engine by German Rheinland Company
OBD verification of ISDe electronically controlled engines for Euro IV export products.
The certification covers the three major Euro IV emission engine models of Dongfeng Cummins, including ISDe, ISLe and ISZ.
three major Euro IV emission engine models
Widely recognized in EU member countries
In order to promote environmental protection and revitalize old machinery and equipment
rejuvenate the life of old mechanical equipment, the NDRC organized
production enterprises and automotive parts remanufacturing enterprises
to carry out automotive parts remanufacturing pilot projects
Dongfeng Cummins took the lead in responding
Carrying out research and development of “remanufacturing” technology
Committed to utilizing renewable resources in advanced forms
In 2009
Dongfeng Cummins took the lead in the production of 13L fully electronically controlled heavy-duty diesel engine.
In addition to meeting the National III emission standard
can also meet Euro III, Euro IV
and the U.S. EPA 2007 emission standards
and has further upgrading capability
It is the development platform for new generation diesel engines
At the same time, Dongfeng Cummins has also taken the lead in upgrading its production line
which can meet the requirements of producing National IV standard engines.
In 2010
Cummins officially started the research and development of the Euro VI standard
At this time, except for Beijing, the National IV standard
National III emission standard was still in force
On July 1, 2013
National IV standard was officially implemented for commercial vehicles nationwide
While taking the lead in introducing advanced emission standards
Dongfeng Cummins also emphasizes on the improvement of environmental protection manufacturing technology.
The realization of National IV emission mainly adopts two technical routes.
The first is through the use of selective catalytic reduction (SCR) technology
Utilizing urea solution to treat the nitrogen oxides in the exhaust gas.
The second is through the particulate trap (DPF)
or Particulate Oxidation Catalytic Converter (DOC)
for particles generated by combustion
Exhaust gas recirculation (EGR) technology that treats particles from combustion
From National III to National IV
30% reduction in NOx value from 5.0 to 3.5
80% reduction in particulate matter from 0.1 to 0.02
Helping the commercial vehicle industry develop in a low-carbon manner
January 1, 2017
The National V emission standard was fully implemented
Dongfeng Cummins has long been involved in the development and production of National V products.
Relevant products cover engines from 140 hp to 375 hp
Meanwhile, it meets the demand of orders from both domestic and overseas markets.
As early as in 2013, Changzhou Public Transportation launched 51 buses
Super Eco Buses” equipped with Dongfeng Cummins National 5 products.
October 18, 2018
Dongfeng Cummins National VI Engine Environmental Type Certification Tests
was officially launched at the Xiangyang Automobile Testing Center.
This is also the first batch of National VI engines in China to be fully certified in accordance with the regulations approved by the Ministry of Ecology and Environment.
Ministry of Ecology and Environment’s approval requirements to start the type certification test for the whole project.
National VI engines are marching toward the market.
January 2019
D-series engines produced by Dongfeng Cummins
4.0, 4.5 and 6.7 engines are announced into the inventory
Among them, the announcements of 4.0 displacement and 6.7 displacement
They are also the first engines of the same class in China to realize the National VI certification.
As a platform developed by Cummins and Dongfeng, the D series engine has been rooted in China for many years.
Rooted in China for many years, from National III, National IV to National V engines
It has won a good reputation among customers.

In the pursuit of green and clean power
Dongfeng Cummins has never stopped
For more than 30 years, Dongfeng Cummins has strictly followed the requirements of
national emission standards
Committed to creating green and environmentally friendly clean power
The concept of “green environmental protection” is molded into the brand.
In the future, facing the challenges brought by the environment, regulations and technological upgrading
and technological upgrades, Dongfeng Cummins will continue to
