Patent ID: 7503308

Claim:
A fuel injection and ignition control device of an engine that controls a fuel injection device that supplies fuel to the engine and an ignition device that ignites said engine, comprising: fuel cut control means for stopping fuel injection from said fuel injection device when it is detected that the engine is in a deceleration state; fuel cut stop time injection restart control means for controlling said fuel injection device so as to increase a fuel injection amount to be higher than a fuel injection amount in normal time by a fuel cut stop time injection amount correction value to restart said fuel injection when a predetermined fuel cut stop condition is met; acceleration time injection amount increase control means for controlling said fuel injection device so as to increase said fuel injection amount by a first acceleration time injection amount correction value when it is detected that an engine accelerating operation is performed; acceleration time injection restart control means for controlling said fuel injection device so as to increase said fuel injection amount to be higher than the fuel injection amount in normal time by a total injection amount correction value calculated by adding a second acceleration time injection amount correction value determined with respect to a fuel cut period and an engine operating state to said first acceleration time injection amount correction value to restart the fuel injection, when it is detected that said engine accelerating operation is performed during said fuel cut; and injection restart time ignition control means for controlling said ignition device so as to determine an injection restart time ignition timing delay amount with respect to said total injection amount correction value and a throttle valve opening degree and delay ignition timing from ignition timing in normal operation by said injection restart time ignition timing delay amount.
