Abstract
A fuel injection apparatus which, when raising fuel of a low viscosity and a low lubricating ability such as gasoline or methanol to a high pressure by a fuel injection pump and injecting it into a combustion chamber of an internal combustion engine etc., prevents the lubricating oil for the fuel injection pump from being diluted by this fuel by pressurizing a separate working oil with a viscosity and lubricating ability higher than the fuel by the fuel injection pump and raising the pressure of the fuel by a diaphragm apparatus by the pressure of the high pressure working oil and thereby supplies the same to the fuel injector.
