Abstract

PURPOSE:To stably start an engine, in an electronic fuel injection controller, by deciding a valve opening time in accordance with cooling water temperature under a starting condition on the basis of procedures different from the prescribed procedures at normal operation. CONSTITUTION:A start decision circuit 511 obtains an AND result from output of a starter switch 17 and output of a comparator circuit 519 of speed NE and prescribed value to decide a start condition. Under this start condition, a basic valve opening time calculation control circuit is closed with a logical circuit, and output of a start valve opening time Ti calculation circuit 512 is fed to an injector. This Ti valve is selected with output of a water temperature TW value register 508 to a corresponding adress value at each clock signal CP1 by adress registers 522, 525, and a main injector start Ti value from the first memory unit 523 and subinjector start Ti value from the second memory unit 526 are selected by said address, and output respectively through registers 524, 527.
