The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaust emissions with conventional, low-cost aftertreatment. This—in addition to the opposed engine architecture—could increase fuel efficiency by 40-50% over the comparable spark-ignited gasoline engine, Achates said.
