Our main pages on this subject:

1.R&D Resources
 Powertrain engineering teams are responsible for ensuring that powertrains meet two requirements : conventional criteria : acceleration, fuel consumption, gearshift smoothness, response, etc. ; regulatory criteria and society's growing demands for better air quality, lower pollutant emissions, and prevention of global warming....
 
2.NOx Trap
 NOx TrapTo reduce pollutant emissions in compliance with European regulations (such as Euro5 standard, due to come in September 2009), Renault's engineers have also been working on the reduction of emissions at-source through improved burning of exhaust gases and post-combustion systems.. The NOx Trap which will be fitted to the 2.0 dCi engine is the best example..
 
3.F4R RS - 200 hp 2.0 16V
 Combustion quality is improved for high standards of efficiency and limited pollutant emissions....
 
4.Innovation at Renault
 Thanks to consistent efforts by automotive industry research teams, pollutant emissions are constantly falling (by around 50 % every five years)....
 
5.2.0 dCi (M9R)
 Maximum torque is reached rapidly, providing smooth dynamic performance from the lowest engine speeds through to the highest, thanks to : a water-cooled variable-nozzle turbocharger, for greater efficiency at high speeds and dynamic acceleration at low speeds (in overtaking, for example), particularly well designed internal aerodynamics to improve engine efficiency, a new-generation common-rail system (1,600 bars) to improve combustion quality, piezo-electric injectors that optimize fuel use and reduce pollutant emissions....
 
6.Preserve air quality
 Thanks to the automotive industry's research efforts, pollutant gas emissions from vehicles are halved every five years.... To reduce pollutant emissions and engine noise, diesel fuel is injected into the combustion chamber in several successive squirts instead of all at once....
 
7.Build for the future
 Hybrid vehicles combine an electric motor with an internal combustion engine to minimize fuel consumption and pollutant emissions.... Renault keeps one step ahead of increasingly tough regulations on pollutant gas emissions, with developments like the NOx trap, which further improves on the catalytic converter's function of cutting down NOx emissions....
