In the low-temperature combustion concept called gasoline direct compression ignition, fuel is ignited by compression rather than by spark, similar to GDi homogeneous charge compression ignition (HCCI). The novel concept offers the potential for diesel-like efficiency while maintaining very low emissions.

This engine will also be more efficient than conventional diesel engines, but without the additional cost incurred by diesel fuel injection and complex exhaust aftertreatment. Although Achates’s work to date has been with diesel, its fundamental approach is suited for advanced combustion regimes using other fuels as well.

The company is working on a net-generation configuration combining VCR with stoichiometric charges and cooled EGR to improve part-load efficiency by means of both a reduction in heat and pumping losses. When running at part loads, the engine operates at high compression ratios to minimized BSFC and maximize the sweet spot on the map.
