Abstract

PURPOSE: To detect generation of vapor reliably by judging generation of vapor when a detection output of physically variable quantity concerning to pressure variation of fuel in delivery pipe deviates from specific range.
CONSTITUTION: Upon judgement of engine stall, a control unit 15 reads in a fuel temperature signal fed from a temperature sensor 19 and a fuel pressure signal fed from a pressure sensor 20. Then temperature rise rate of fuel is operated and compared with a setting level. (Minimum temperature rise rate obtainable upon generation of vapor in fuel in the delivery pipe 2). If the temperature rise rate is higher than the setting level, it is judged that vapor is generated in fuel, and if the temperature rise is not higher than the setting level and the fuel temperature is not starting to lower, it is judged that vapor is not produced. When the temperature rise rate is higher than the setting level and the fuel temperature is not higher than saturation temperature, it is judged that vapor has been eliminated. Consequently, erroneous or non-detection of vapor can be avoided.
