Project Details


An international European consortium of 17 large industry and research organisations on various automotive fields of expertise, the “PaREGEn” consortium will demonstrate, at up to TRL 7, a new generation of gasoline direct injection engined vehicles achieving a 15% reduction in CO2 emissions through the optimal combination of advanced engine and robust aftertreatment technologies.Modelling and simulation software will be verified and used to improve the design and the capability of the engines. Two demonstration vehicles, one Mercedes E180 and one Jaguar XE, will comply with upcoming Euro 6 RDE limits with particle number emissions measured to a 10 nm dia. size threshold.The overall concept and technical approach comprises three major elements:
> Research for improved understanding> Innovation and demonstration of new technologies combinations, where the developed know-how, software and controlstrategies are implemented in two novel optimised gasoline engined vehicles> Independent assessment of their impact element to track the progress of the project towards reaching the targets.

Key findings

In spite of increasingly stringent emission standards, growing road traffic in Europe results in detrimental effects on the environment and public health to a level that is becoming unsustainable.

The challenge is to develop a new generation of engine technologies that are truly and significantly more fuel efficient than the best 2015 equivalents under real driving conditions, and to demonstrate pollutant emission levels from these technologies can meet with the upcoming Euro 6 RDE limits and particle number emissions measured with a 10 nm size threshold.

The PaREGEn project will take the lead in demonstrating at up to TRL 7 a new generation of gasoline direct injection engines achieving a ≥ 15% reduction in CO2 emissions through the optimal combination of advanced engine and robust aftertreatment technologies.

PaREGEn will result in the capability for designing and creating future gasoline engines, powertrains and vehicles complying with EU6 RDE legislation with PN emissions down to 10 nm in size. Market entry and technology roll out of the methods for development of optimal GDI engines are foreseen for 2020 and onwards.
