<p><P>PROBLEM TO BE SOLVED: To provide a fuel injection control apparatus which realizes premix compression ignition combustion that is low HC and low fuel consumption. <P>SOLUTION: In a compression stroke, a fuel injection valve 2 injects a first portion of fuel immediately after -28°ATDC. Immediately after this injection, the fuel injection valve 2 injects a second portion of the fuel as close as possible to the first injection without overlapping. The amount of the fuel injected in the second injection is remainder obtained by subtracting the amount of the fuel injected in the first injection from the amount of the fuel required to obtain a required torque, and is more than the amount of the fuel injected in the first injection. Next, the fuel injection valve 2 injects a first portion of the fuel immediately after -18°ATDC. The amount of the fuel injected at this time is approximately double the amount of the fuel injected in the first injection at -28°ATDC timing and less than the amount of the fuel injected in the second injection. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
