Title:
FAILURE DETERMINATION DEVICE AND SAFETY DEVICE FOR INTERNAL COMBUSTION ENGINE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/007720
Kind Code:
A1
Abstract:
A failure determination device for an internal combustion engine system (100A)
constructed from an internal combustion engine (50A) and a pulse charging valve
(15A) for performing pulse supercharging by opening and closing an air intake
path communicated with the internal combustion engine (50A). The failure determination
device has pulse-supercharging-failure determination means that is an ECU
(1A) for determining a failure relating to pulse supercharging and determining,
based on combustion conditions of each cylinder of the engine (50A), whether
there is a failure relating to pulse supercharging. Also, the ECU (1A) has means
for deciding, depending on conditions of the failure relating to pulse supercharging,
conditions for causing a vehicle to perform evacuation travel.
