PURPOSE: A fuel supplying system for a compression natural gas engine is provided to form a strong turbulent flow and a fast filling velocity of fuel gas in a combustion chamber by employing a fuel gas induction injecting adaptor of a simple structure instead of changing the structure of an engine, thereby increasing the combustion efficiency and improving the vehicle performance. CONSTITUTION: A fuel supplying system for a compression natural gas engine includes a fuel cylinder for storing compression natural gas, a regulator for controlling pressure of fuel gas supplied from the fuel cylinder, a fuel rail for distributing the fuel gas supplied from the regulator to respective cylinders of an engine, an injector(16) for injecting the fuel gas distributed from the fuel rail to combustion chambers(R) in the cylinders, and a fuel gas induction injecting adaptor(30) having a mounting part(32) to be coupled with the injector, and a nozzle part(34) extended from the mounting part for introducing the fuel gas injected from the injector into the combustion chambers not to be mixed with air in an intake manifold(M) but maintain motion energy and positioned in the vicinity of a rear surface of an intake valve(V) at a front end with an injection angle for achieving a maximum heat efficiency.
