Apr 8, 2024 | China News | 0 comments

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

Dongfeng Cummins will continue to deepen the

“Green” concept and fulfill its social responsibilities

leading the “green” development of the commercial vehicle power industry!
