Summary:

This paper introduces for the first time a new concept infuel/air handling technology that has been shown to deliverreductions in fuel consumption and CO₂ emissions in port-injectedgasoline engines. Whilst direct injection provides a route tosignificant improvements in gasoline engine efficiency there aredrawbacks in terms of cost, complexity, particulate emissions andNVH. The technology presented in this paper offers a route toimproving the efficiency of the conventional port injectedengine.The technology essentially consists of a system that mixes fueland air, promotes exceptional levels of swirl and provides a lowlevel supercharging effect. The system sits between the fuelinjector and the inlet port, with one system per cylinder.A simple prototype system has been fitted to a 1.6-liter FordFocus, with independent testing showing up to 9% reduction in CO₂emissions (and commensurate reductions in fuel consumption) and upto 40% reduction in NOx.Results of independent, vehicle level tests using the standardNew European Drive Cycle are presented to show how the technologyreduces key exhaust gas emissions through different phases of thetest
