METHOD FOR OPERATING A DIRECT-INJECTION SPARK-ASSISTED COMPRESSION-IGNITION ENGINE |
摘要 |
A compression-ignition internal combustion engine includes a plurality of combustion chambers operating in a four-stroke combustion cycle and is configured to operate at a geometric compression ratio greater than 10:1. A method for operating a the engine includes forming a fuel/air charge by injecting fuel into each combustion chamber during a compression stroke, wherein the injection is completed prior to any combustion within the combustion chamber. The method further includes operating the engine to manage temperature of the fuel/air charge in the combustion chamber below an auto-ignition point of the fuel/air charge, and providing a spark discharge in the combustion chamber subsequent to injecting the fuel and in advance of the fuel/air charge achieving an auto-ignition temperature.
