Title:
EVAPORATED FUEL TREATMENT DEVICE
Document Type and Number:
Japanese Patent JP2018013110
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology to determine a purge concentration while considering delay between timing when the purge concentration is specified and timing of arrival at an internal combustion engine.SOLUTION: An evaporated fuel treatment device includes a memory having 300 storage regions 104a from 1st to 300th, and a control portion. The control portion stores a purge concentration of purge gas positioned in a Kth section obtained by dividing a purge passage 24 in which the purge gas flows between a canister 14 and a control valve 34, into 300 sections from 1st to 300th successively from the canister 14 to the control valve 34, in the Kth storage region 104a among 300 storage regions 104a, the purge concentration stored in the storage regions 104a from Mth to 1st is moved from 300th to 300-M+1th according to flow of the purge gas, and the specified purge concentration is stored in the storage regions 104a from the 300-Mth to 1st.SELECTED DRAWING: Figure 2
