摘要： There is provided a start control apparatus for an internal combustion engine (1) which starts the engine with injecting fuel to each cylinder (2) of the internal combustion engine in an intake stroke. The apparatus comprises a stop position distinction device (20) which distinguishes a piston position at a time of a stop of the internal combustion engine, and a fuel injection amount control device (20) which specifies a cylinder in which a piston stops in the intake stroke based on a distinction result of the stop position distinction device and which increases a fuel injection amount at starting for the specified cylinder more than a fuel injection amount for other cylinders. The fuel injection amount can also be controlled as a function of position in which the piston stops in the intake stroke. The invention allows to restrain self ignition at starting.

摘要： PROBLEM TO BE SOLVED: To clarify the relationship between a heating value of a heater and the shape of a fuel adsorbing layer 4 to obtain the temperature regulating effect over the whole area of the fuel adsorbing layer 4. SOLUTION: The fuel adsorbing layer 4 formed inside of a canister is defined into an upper adsorbing layer 4A and a lower adsorbing layer 4b by a partitioning plate 13 in which a heater is buried. The relationship between the heating value of the heater and a thickness X of the upper adsorbing layer 4A and the lower adsorbing layer 4B is determined to satisfy that a temperature of a part nearest to a heating face of the heater, of the fuel adsorbing layer 4 is lower than an ignition point of the fuel, and a temperature of a part farthermost from the heating face of the heater is higher than a boiling point of the fuel. Whereby the desorbing performance of activated carbon C can be improved by heating the fuel adsorbing layer 4 by the heater in desorption, and the approximately full amount of the adsorbed fuel vapor can be desorbed. As a result, as the fuel vapor does not remain in the canister, the fuel vapor flowing in adsorption can be surely and completely adsorbed.
