Ignition control of homogeneous-charge compression ignition (HCCI) combustion through adaptation of the fuel molecular structure by reaction with ozone

摘要: The present paper describes a method of controlling the time ignition in homogeneous-charge compression (HCCI) combustion. In described experiments some control timing HCCI combustion is achieved through alteration fuel molecular structure using chemical reaction with ozone, prior to introduction into chamber. Controlling essential, achieving high thermal efficiency and low pollutant emission engine operation. To this end, should occur vicinity piston top-dead-centre (TDC), point maximum fuel–air charge. proposes charge by adapting ignitability ozone. Ozone can be readily produced air conjunction corona discharge ozoniser may brought contact chamber before its injection engine. It was shown that an acetal which has undergone treatment ignites earlier during cycle combustion, than not as result changes observed consisted primarily formation peroxides within fuel. This used operate mode over varying proportions previously treated ozone showed could controlled, whilst keeping other parameters such load speed engine, pressure temperature intake fuel, constant.
