Abstract: PURPOSE: A method for setting up an idle fuel amount by density of evaporation gas is provided to control an amount of fuel supplied in the case that an engine is idle. CONSTITUTION: A temperature of cooling water and the time elapsed after starting an engine are measured to judge whether the engine is in an idle state(S11). A pressure of a fuel tank is measured(S13). The density of evaporation gas generated from fuel is measured by the measured pressure of the fuel tank and the temperature of cooling water(S15). A compensation value for idle fuel amount is set up through the measured density of the evaporation gas(S17). An idle fuel amount is decided by applying the fuel amount compensation value to the idle fuel amount(S19).
