ABSTRACT:
A fuel supply system including an evaporated fuel gas purge system measuring a purge gas quantity in purging which comprises: evaporated fuel gas adsorption means having at least a suction port, an exhaust port, a purge port, a chamber in which an adsorption agent that adsorbs an evaporated fuel gas is filled, and detecting means for detecting a quantity of adsorption by the adsorption agent; purge means for purging an adsorbed gas; pressure detecting means for detecting a pressure at a purge gas exhaust part; and suction air temperature detecting means for detecting a temperature of suction air which flows in purging the adsorbed gas. By using the measured value of the purge gas quantity, a fuel injection quantity is corrected, which is determined by an air quantity for suction of the engine corresponding with the purge gas quantity.
