Eminox

Upgrading City Buses to Reduce Emissions

• Eminox was established in 1978

• We employ around 220 people in 6 countries

• We design and manufacture exhaust and emission control systems for heavy duty diesel engines

• We have supplied approx. 70,000 emission control systems to date

• Our systems are used across Europe and further afield forAir Quality clean up programmes

About Eminox

City Pollution

• Particulate Matter (PM) and Nitrogen Oxides (NOx) are damaging to health and the environment

• Many cities across Europe are failing to meet legal limits for PM and NO2

• There is no safe limit for exposure to PM (World Health Organisation)

• The link between black carbon (PM) and global warming is now internationally recognised

Retrofit

• New vehicles are now manufactured with technology that reduces their emissions of PM and NOx

• There are many older buses still in service – reducing pollution from these buses can have a major impact

• These can be retrofitted with emissions reduction systems at a fraction of the cost of new buses

• With SCRT technology 15 buses can be upgraded to Euro V for the cost of 1 new bus

Eminox SCRT has been used inEurope’s largest retrofit programmes

• Belgium - 247 buses upgraded for bus operator DeLijn

• Spain – More than 400 buses upgraded in Barcelona

• Sweden – around 300 systems fitted to meet local traffic emissions requirements for PM and NOx

• Edinburgh - 43 Lothian buses upgraded

• Oxford – 26 systems fitted

SCRT ® Retrofit

SCRT® System

• Combines two technologies:

CRT® (Continuously Regenerating Trap)

SCR (Selective Catalytic Reduction)

• Same technology as used for Euro V, EEV and Euro VI

• Advanced emissions technology reduces • particulate matter• nitrogen oxides• hydrocarbons• carbon monoxide

SCRT® System

Catalyst:Filter

SCR Catalyst Clean Up Catalyst

SCRT® System

• Vehicles as old as Euro II can be upgraded to the latest Euro V emissions standards

• This requires71% reduction in NOx86% reduction in PM

• In independent tests the Eminox SCRT achieved equivalent reductions

Real World NOx Reduction

Real World NOx Reduction

Retrofit is specifically calibrated for urban conditions with proven real world NOx reduction

DeLijn Belgium

• DeLijn public transport operator for Flanders region

• Trial of SCRT technology Nov 2006

• Consistent NOx reduction 75 – 80%

• 246 buses retrofitted including city buses in Antwerp and Limburg

SCRT® Developments

• New SCRT system used for pilot project

• New catalysts and software

• Test results from Dennis Dart

• 88% NOx Reduction

• 50% NO2 Reduction

• On urban operating cycle

• Up to 1000 buses will be upgraded

• Retrofit of SCRT Systems is a cost effective route to upgrading vehicles:- Euro II to Euro IV- Euro III to Euro V and EEV

• Upgrade 15 buses for the cost of 1 new bus

• Tailored for urban driving conditions – delivering reliable NOx reduction on city buses

• Proven in independent tests and real world application
