Title: Fuel property determination device for internal combustion engine
Inventor: MAJIMA YOSHIHIRO
IPC: F02D41/06
Filed: 2000-05-24
Abstract: PROBLEM TO BE SOLVED: To precisely determine fuel property. SOLUTION: An intake air amount integrated value TAF and a fuel injection amount integrated value TTAU are calculated by the time when an air-fuel ratio sensor is activated from start and an air-fuel ratio detected by the sensor reaches a stoichiometric air fuel ratio 14.7, and a fuel property determination value TNEN is found from a following equation: TNEN=TTAU×14.7-TAF.  Here, a value (TTAU×14.7) found by multiplying the fuel injection amount integrated value TTAU and the stoichiometric air fuel ratio 14.7 together corresponds to an air amount necessary for carrying out a complete combustion of the fuel injection amount integrated value TTAU, and a difference TNEN between the multiplied value (TTAU×14.7) and the actual intake air amount integrated value TAF is generated in accordance with a fuel amount contributed to combustion (mainly corresponding to a wet value) and a degree of decrease of fuel evaporativity due to heavy gravity property of the fuel. Accordingly, the difference TNEN serves as a parameter quantitatively indicating the fuel property.
