<P>PROBLEM TO BE SOLVED: To realize good control characteristics in a high-pressure fuel pump of a direct injection engine. <P>SOLUTION: An engine ECU performs a program including a step of detecting an engine speed NE when recovering requirements for injection from an injector for cylinder injection are established (YES in S230), a step of detecting the pressure (fuel pressure) P of a fuel in a high-pressure delivery pipe, a step of detecting a requested discharge amount Q, and a step (S240) of immediately starting a feedback control including a step of calculating a crank angle indicating the timing of closing an electromagnetic spill valve which meets the requirement of the requested discharge amount Q. <P>COPYRIGHT: (C)2007,JPO&INPIT |
