Abstract
In a fuel supply system for internal combustion engines, a fuel delivery pipe to which fuel injectors are mounted through respective connectors is connected to a fuel tank through a fuel piping without return piping. At least one of the connectors of the injectors is extended upwardly to open at an upper portion in the delivery pipe. In the event that air or fuel vapor is generated in the fuel supply system, it is gradually introduced into the delivery pipe and rapidly purged with fuel through the extended connectors and the injectors when the injectors inject fuel into an engine. In order to improve engine cranking operation at high temperature condition, fuel injection period is extended so that vapor or air in the fuel is purged through the injectors. The extension of fuel injection period is terminated as soon as the initial explosion in the engine is detected.
