Abstract
A fuel regulation apparatus of an engine for a model which is possible to regulate the flow rate of the fuel according to the rotational frequency of the engine is provided. A main body,of a fuel regulation apparatus,is provided with a fuel inlet,, a fuel outlet,, and an air inlet,to which air pressure from a crankcase is applied. The inlet,and the outlet,are connected therewith through a passage,having a seat face,. A regulating valve,is placed in the passage,to close the seat face,. A spring,pushes the regulating valve,in such a direction as to close the seat face. The other end of the regulating valve,is in contact with a piston,. A position of an air inlet,can be adjusted by a screw,. The spring pushes the piston,in such a direction as to open the seat face,. The outlet,is connected to a fuel injection apparatus. The fuel injection apparatus injects the fuel into a crankcase. The piston is pushed according to air pressure in the crankcase,corresponding to rotational frequency and the seat face is opened. The flow rate can be controlled according to the rotational frequency of the engine. The fuel which is apt to be insufficient at the time of high speed can be increased and the fuel which is apt to be dense at the time of low speed can be throttled.
