For the problem of global warming, air pollution and drying up of the fossil fuel, a automotive engine has been demanded with the technological development which can be high efficiency combustion and reduce the emissions of toxic substance(CO 2 , NO x , CO, HC, SO x , PM). In recent years, gasoline direct injection that injects fuel directly in a cylinder have attracted attention as the fuel supply method of automotive gasoline engine, it enables high efficiency combustion and low CO 2 emissions. However it occurs unburned emissions because of the fuel attach for direct injection, furthermore, stratified-charge operation is prone to combustion instabilities because fuel is injected late during the compression stroke. This study has been carried out to examine the effect of multi-point ignitions on combustion characteristics for heterogeneous combustion field by using impinging injection in a constant volume chamber. The main conclusions are as follows; 1) Under the heterogeneous combustion field, the maximum burning pressure increases and the total burning time decreases by using the ignition timing difference than the three-point simultaneous ignitions at same overall equivalence ratio. 2) The maximum heat release rate increases by using the ignition timing difference than the three-point simultaneous ignitions at same overall equivalence ratio. 3) It is possible to control the combustion behavior by using the ignition timing difference under the increasing the initial pressure. Key Words : Heterogeneous combustion, Multi-point ignition,
