Title:

EVAPORATED FUEL TREATMENT DEVICE FOR OUTBOARD ENGINE

Document Type and Number:

Japanese Patent JP2007120473

Kind Code:

A

Abstract:

To prevent deterioration of a function of a canister caused by flow-in of liquid fuel from a vapor separator.

A purge valve 74 for controlling delivery of evaporated fuel to an intake device is provided in a half way of a purge pipe 73 connecting the canister 51 and an intake manifold 31. An air vent valve 76 for controlling introduction of outside air into the canister 51 is provided in a half way of an air vent pipe 75 connected to the canister 51. A canister protecting valve 72 is arranged in a halfway of a fuel vapor hose 71 connecting the vapor separator 24 and the canister 51. The canister protecting valve 72 prevents flow-in of the liquid fuel from the vapor separator 24 to the canister 51 by being in a closed state. An ECU 63 controls opening and closing of the canister protecting valve 72 based on a tilt angle calculated based on a tilt angle signal θMOT from an outboard engine angle detection device 83 and a detection signal θB from an outboard engine angle detection device 90.
