The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaust emissions with conventional, low-cost 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.
