直噴火花点火式エンジンの制御装置
Document Type and Number:
Japanese Patent JP4055425
Kind Code:
B2
Abstract:
To enable to realize initial proper combustion irrespective of accumulation of deposit to a tip part of an injector 7.
A divergent angle of fuel spray becomes large (θ1→θ2) by accumulation of the deposit to the tip part of the injector 7, and penetration force of spray decreases (L1→L2). Stratified charge combustion is enabled by estimating the amount of accumulation of the deposit, and leading an angle of fuel injection time according to this or lagging an angle of ignition time.
