ASSIST GAS FUEL INJECTION MECHANISM FOR 2-CYCLE INTERNAL COMBUSTION ENGINE |
摘要 |
In an assist gas fuel injection mechanism for 2-cycle internal combustion engine comprising a chamber communicated to a combustion chamber through a communicating passage, a rotary valve provided in the communicating passage for controlling the opening and closing of the communicating passage, and a fuel injection device provided in the communicating passage between the rotary valve and the chamber, such that a highly compressed gas from the chamber and a fuel from the fuel injection device are mixed with each other and a concentrated mixture gas is supplied to the combustion chamber through the communicating passage, to minimize the clearance between a valve body and a housing of the rotary valve, to reduce leakage of an assist gas for injection, and contrive a reduction in the size of the assist gas fuel injection mechanism. An assist gas fuel injection mechanism for 2-cycle internal combustion engine characterized in that a protective layer is provided on the outside surface of the valve body of the rotary valve by using a material which is softer than the valve body of the rotary valve and the housing of the rotary valve and which is susceptible to plastic deformation.
