Title: Accumulator fuel injection device
Inventor: INABA TAKAYOSHI
IPC: F02D41/38
Filed: 2002-04-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a common rail type fuel injection system that prevents overshoot or undershoot when a pump discharge amount, pump pressure-feed amount, or fuel pressure in a common rail reaches target fuel pressure (PFIN), by preventing excessive correction of integral item upon abrupt change in PFIN.  <P>SOLUTION: In a control logic, a feedback correction amount (IFB) as a correction item calculated from an IP control is added to a drive current value (IPMP) calculated based on an SCV drive current value calculation map by using such as a required discharge amount and actual fuel pressure to calculate final IPMP. When the PFIN is abruptly changed, the integral item is calculated from eccentricity of an actual fuel pressure from a second target fuel pressure excluding a target fuel pressure change amount, so that the integral item can be calculated only by a fuel pressure change component. Therefore, in the integral item, the target fuel pressure change component in never mistaken as a fuel pressure change component.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-04-15
Abstract: <P>PROBLEM TO BE SOLVED: To keep good air-fuel ratio accuracy regardless of response of an evaporation concentration sensor disposed on an intake side, with regard to a vaporized fuel treating device for an internal combustion engine.  <P>SOLUTION: Purge controlled variables are slightly increased while a feedback control of a fuel injection amount is performed based on an exhaust air- fuel ratio (step 102). A virtual air-fuel ratio that is implemented when the feedback control is not executed, is calculated (step 104). Allowable purge controlled variables in which the virtual air-fuel ratio reaches an allowable air-fuel ratio, is detected (steps 106, 108). The purge controlled variables are changed stepwise by the allowable purge controlled variables (step 110). Reducing correction of the fuel injection amount is performed based on the output from the evaporation concentration sensor (step 112). The response of the evaporation concentration sensor is estimated depending on the output behavior (an noninversion period) of an exhaust O<SB>2</SB>sensor (step 116). A guard is set to a change speed of the purge controlled variables based on the response (step 118).  <P>COPYRIGHT: (C)2004,JPO
