The Application of Conical and HL Spray System in the Research of Homogenous Premixed combustion

摘要

In homogeneous premixed combustion, low impingement and good atomization injector should be applied if the early injection premixture preparation is adopted. With the application of the low-penetration injectors-conical spray injector and HL spray injector, the homogeneous premixture in diesel engine is well prepared. The characteristics of the premixed combustion of the conical spray premixture are studied. With the purpose of testing the HL spray injector's capability in dual mode diesel/homogeneous premixed engine, the comparison experiments of HL spray and hole type spray combustion were carried out. The experiments prove the competence of HL spray injector in dual mode diesel engine.
