Document Type and Number:
Japanese Patent JP2884472
Kind Code:
B2
Abstract:
To detect the volatility of fuel accurately and speedily, a system for an internal combustion engine is arranged to gradually increase only the fuel supply quantity for a specified cylinder, while monitoring a variation of a combustion pressure in the specified cylinder, until the variation exceeds a predetermined level. The amount of fuel increase (such as AFR) obtained at the time the variation exceeds the predetermined level is used as a parameter representing the volatility of the fuel.
