Title:
FUEL CONTROL DEVICE OF ENGINE
Document Type and Number:
Japanese Patent JP3536310
Kind Code:
B2
Abstract:
PURPOSE: To provide a means capable of preventing occurrence of slippage of an air fuel ratio at the time of introduction of an EGR for an engine devised to set a fuel injection amount in accordance with a direct entrance rate (adhesion rate) and a take-away rate.
CONSTITUTION: In an engine CE, a direct entrance rate and a take-away rate of fuel are set by a control unit C, and a fuel injection amount is decided in accordance with them. At the time when an EGR valve 17 is opened and an EGR is introduced into an air intake system, the direct entrance rate and the take-away rate are corrected in the increasing direction, influence of air intake port wall temperature rise by EGR introduction is compensated, the fuel injection amount is properly set regardless of existence of the EGR introduction, and occurrence of slippage of an air fuel ratio is prevented.
