CORE Concept

2010 CLC Most Innovative Technical Solution Winner

Core is a new combustion strategy for internal combustion engines designed to increase engine efficiency while simultaneously lowering health impacting pollutants. Core utilizes a patent pending process to inject fuels (either bio-derived or petroleum based) of different reactivity into the engine, to create a high efficiency low-temperature combustion event, as seen in Figure 2.

Core has been experimentally and computationally validated to increase engine efficiency 77% higher than conventional gasoline engines and 20% higher than conventional diesel engines, as shown in Figure 3.

If fully implemented, using a CORE engine fueled by biofuels combined with a hybrid powertrain can lower GHG emissions by up to 60% as compared to a conventional gasoline engine (see Figure 8).

By fully implementing the CORE system (otherwise known as RCCI, or Reactivity Controlled Compression Ignition) it is possible to decrease GHG emissions in the US by 4 billion lbs/yr. This correlates to saving 4.7 MBOD of oil from being imported (nearly the amount imported from Saudi Arabia) to the US, saving nearly 142 billion dollars a day.
