The new RENAULT Energy dCi 140kW 2,3l Diesel engine

Renault knows that radically curbing fuel consumption and CO2 emissions is vital in today's world. Renault will remain among the leading companies for CO2 emissions by combining a wide offer low-emission / zero-emissions vehicles with new technologies for conventional powertrains such as a new generation of twin-turbocharged engines, developed in synergy.
This paper will describe how the 2,3-liter Energy dCi engine is evolving in part of this trend, taking advantage of new CO2 technologies without giving up its core genetics : affordability and versatility.
This new generation covers a large range of applications in the Renault-Nissan Alliance (LCV including HDV and others).
The development was focused on CO2 and TCO (total cost of ownership) reduction, as well as preparing next regulation evolution. Its CO2 emission is 10%~15% lower than those of the previous generation and the engine is Euro6 / EuroVI ready.
Besides the introduction of state-of-the-art technologies such as high injection pressure, twin turbocharger, main challenge was to make a versatile engine to cover all applications with maximum commonality to keep it affordable and preserve existing facilities.
