E4 emission control in Korea

2017. 7. 26.


HC (Hydrocarbons) Main constituent of petroleum

Unburned in combustion chamber of ICE

Gasoline engine - 3,000 ppm , Deisel – 300 ppm

CO (Carbon Monoxide)

Caused from partial oxidation in combustion chamber of ICE

NOx (Nitric Oxides) Produced during combustion, especially at high temperature ( >1700℃)

Main precursor for tropospheric ozone

Harmful to human health

PM (Particulate Matter) Generated from unburned carbon during burning of fossil fuel in ICE

1991 The effectivation of a clean air conservation act

1996 Phase-in mode of weight (US regulation, CVS-75 mode)

Oct, 2000 Submit proposal of tighten up regulation (Propose phased milestone analogous to Viet Nam Decision No. 49)

Apply EU standards(EURO specification) Apply American standards

2001 ~ 2002 EURO 2 regulation

2003 EURO 3 regulation Introduction of US Califonia LEV program (similar with EURO 3)

Jan, 2006 EURO 4 regulation (ULSD spreading nationwide) Introduction of US Califonia ULEV program (similar with EURO 4)

The emission standards in Vietnam are way behind the neighboring countries.

Vietnam plans to jump to Euro-4(cars) and Euro-3(MCs) from Euro-2 in 2017.

EGR ( with DOC + POC ) deprives the combustion event of some of its oxygen by introducing cooled exhaust gas, which is lower in oxygen,

into the intake system, thereby reducing the combustion temperature and lowering NOx production

Strategy SCR EGR + DOC + POC

Pros

• Permits more optimized combustion

• Can enable better fuel efficiency/power

• No concerns about engine durability/oil degradation

• End product is nitrogen, water and carbon dioxide

• Urea not classified as hazardous to health

• Does not require additional onboard hardware

• Does not require the use of an additional fluid

• No loss of payload

• No impact on service intervals

• No driver intervention necessary for compliance

Cons

• System adds weight

• Adequate urea supply infrastructure is mandatory

• Purchasing urea is additional cost

• System, including sensors and other compliance-related

devices, must be maintained

• Require heated storage because of urea freezing

• Most effective at constant speeds and high loads; least

in stop/start

• Urea (also in some fertilizers) is a water

pollutant/harmful to fish

• Increases heat rejection, creating need for greater

cooling capacity

• Decreases power density, fuel efficiency

• Potential engine durability and oil degradation issues

• Less combustion efficiency produces increased

particulate matter, hydrocarbon, carbon monoxide

Target of JV Eco&Dream & VEAM Co. signed MOU for making JV in Vietnam

Provide the catalyst system to Car and Motorcycle manufacturers for EURO 4 regulation.

Establish catalyst coating and canning plant in Vietnam and produce “made in Vietnam”

catalyst system.

Marketing to Vietnam domestic market and export to neighboring countries.

Technical issue Provide cost effective emission control system to meet EURO 4 regulation.

Offer various solution to clients based on E&D’s extensive experience both OEMs and Retrofit

markets


Regulations Regulations have been growing stringent worldwide to reduce pollutants from the automotive.

Vietnam is going to implement new emission standards(Euro4 for cars and Euro3 for MCs) in 2017.

Catalyst technologies for Euro-4 E&D has developed all kinds of catalysts to meet the Euro-4 emission regulation, such as DOC,

POC, DPF, SCR, LNT & TWC.

Since 2004, E&D has supplied various catalysts and after-treatment systems for OEM & retrofit

market in Korea. Based on these references, we have accumulated a lot of experience to design

and apply our products to meet emission regulations Euro-4 or more.

E&D can provide all the technical solutions for OEM makers in Vietnam which has their own

strategy for Euro-4 regulation.

To achieve our goal in Vietnam, E&D will do its best to launch JV venture with VEAM and supply

product made in Vietnam.
