Renault Plans to Further Curb Diesel Emissions

Even though it was German rival Volkswagen making headlines over the recent diesel emissions scandal, French carmaker Renault was also caught with its pants down when it comes to diesel emissions. To its credit, Renault responded to cheating claims with an immediate recall of 15,800 vehicles. More recently, however, Renault announced a plan to introduce a new technology to its diesel lineup that it says will help reduce- if not remove- the kind of conditions that lead to discrepancies between testing and real-world environments.

 

Renault’s New EGR Diesel Emissions Tech

Renault’s new system will increase the amount of exhaust gas recirculation (EGR) compared to their current system. The EGR gasses are added into the intake mix ahead of the turbo and intercooler. The second “phase” will focus on improved catalytic converter technology and revised ECU mapping to take advantage of the new hardware.

It remains to be seen what kind of impact, exactly, these changes will make on Renault emissions- but with more and more manufacturers failing to meet emissions standards in real-world driving conditions, you can expect more and more similar emissions technologies to be announced in the coming months.

What do you guys think? Will technological advancements save diesel from extinction? Has the “clean diesel” ship sailed away on the winds of Tesla hype? Let us know what you think in the comments section at the bottom of the page.
