Gasoline compression ignition
Compression ignition engines are among the most energy efficient internal combustion engines on the road today.
The issue, however, is that the diesel fuel that is used to power the engine produces soot and NOx emissions. This requires complex and costly after-treatment systems to reduce emissions of these pollutants into the environment.
This is common for many conventional diesel engines that use conventional diesel fuel.
An innovation that we are actively pursuing is the unconventional use of a gasoline fuel in a modern compression ignition engine. Gasoline Compression Ignition (GCI) can increase the efficiency of gasoline engines by harnessing the efficiency of the diesel compression ignition architecture. If coupled with modern after-treatment systems, it has the potential to reduce engine emissions substantially.
Our early prototypes demonstrate that GCI could reduce fuel consumption and CO2 emissions by up to 25% compared to conventional gasoline vehicles.
To realize this potential, we have partnered with global automakers and leading technology developers to accelerate fleet deployment opportunities, particularly in sectors and markets that are unlikely to be fully electrified soon.
We recently demonstrated with a leading engine manufacturer that a heavy-duty truck in China could potentially achieve lower pollutant emissions by optimizing the fuel, engine, and after-treatment systems. This collaboration resulted in NOx emissions that are 90% below the current US regulatory standard, when tested under the combined heavy-duty Federal Test Procedure (FTP) cycle.
