DRIVING METHOD AND DRIVE MECHANISM OF DIRECT INJECTION TYPE INTERNAL COMBUSTION ENGINE, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To accurately adjust a fuel pressure within a fuel accumulator even when a pressure sensor indicates incorrectly. SOLUTION: The fuel pressure of the fuel accumulator is adjusted to a pressure target figure using control variables of air fuel mixture control unit of an internal combustion engine, including a difference between an air-fuel ratio that exists in an exhaust pipe and a target air-fuel ratio.
