The Euro VI challenge
From 1st January 2014, all vehicles over 3.5t newly registered in Europe must comply with the Euro VI emissions standard which makes compulsory to reduce nitrous oxide emissions by 80% and particle emissions by 50 % compared to the Euro V stage.
Spectacular progress has been made in reducing pollutant emissions generated by HGV engines. Coming into force in 1990, the so-called ‘Euro’ European standards require manufacturers to bring in regular reductions in emission levels of 4 atmospheric pollutants:
- Nitrogen oxides – Monoxide and Dioxide (NOx)
- Solid particulates (PM)
- Unburnt residual hydrocarbons (HC)
- Carbon monoxide (CO)
As a result of these regulations, in little more than 20 years, NOx emissions will have been reduced by 98% and particle emissions by 97%.
Reliability and control of fuel consumption
Renault Trucks provides its customers with engines that comply with the EURO VI standard with fuel consumption, operation and reliability levels similar or superior to those of EURO V engines: DTI 5 (210 hp, 240 hp) and DTI 8 (250 hp, 280 hp, 320 hp) for medium duty trucks ; DTI 11 (380 hp, 430 hp, 460 hp) and DTI 13 (440 hp, 480 hp, 520 hp) for heavy duty trucks.
They use the technology best suited to the different vehicle uses. Each engine associated with an after-treatment system of exhaust gas operates at temperatures high enough to guarantee optimum performance.
The after-treatment system incorporates an oxidation catalyzer, a particulate filter that substantially reduces particulate emissions, including ultra-fine particulates, and a selective catalytic reduction system (SCR) of nitrogen oxydes.
The compactness of the system optimizes the maximum capacity of the fuel tank and the AdBlue urea solution reservoir as well as the practicability of vehicle body structures.
