Developing the next generation of efficient lean gasoline engines with ultrafine particulate control

The Particle Reduced, Efficient Gasoline Engines (PaREGEn) project focuses on the twin challenges of improving the fuel efficiency of next-generation gasoline engines whilst controlling their emissions of particles.

Objective

The project has committed to demonstrate a 15% CO2 reduction in mid- to premium-sized passenger cars, along with real driving emissions target compliance including measurement of particles as small as 10nm in diameter.

Ricardo is coordinating the research initiative as part of a 17-partner consortium, representing all sectors of the European automotive industry.

Customer Benefit

The gasoline engine is likely to continue playing a significant role in passenger cars in the coming decade, particularly in mid- to premium-sized passenger cars used for long journeys.

Manufacturers of components and vehicles will need to continue to meet the demand for powertrain technology. The PaREGEn project will demonstrate both the technical and process development routes to support this need with the gasoline engine.

Technology

Using state-of-the-art development techniques, such as optically accessed single cylinder engines, a range of modelling and simulation tools, and the application of novel engine componentry, the optimal trade-offs between cleanliness and efficiency are being identified for such next-generation gasoline engines.

The overall concept and technical approach comprise of three major elements:

  1. Research for improved understanding
  2. Innovation and demonstration of new technology combinations where the developed know-how, software and control strategies are implemented in two novel optimised gasoline engine vehicles
  3. Independent assessment of their performance and impact to track the progress of the project towards reaching the targets.


Specifically, as well as coordinating the project, Ricardo and its work package partners are developing a homogeneous lean-burn, direct-injection engine matched with a lean gasoline aftertreatment system at up to TRL 7.

A full demonstrator vehicle has been built and is undergoing development testing.
