ABSTRACT:
A primary low viscosity fuel and a secondary high viscosity fuel are fed to an injection pump including a plunger which reciprocates and rotates within a bore in a pump housing. The upper end of the plunger defines with the upper end of the bore a mixing chamber. The mixing chamber is connected through a check valve with a fuel injector for injecting mixed fuel into the combustion chamber of an engine. The plunger has a helical groove thereon which is in communication with the mixing chamber. Primary fuel is fed directly into the mixing chamber. The secondary fuel is fed into an annular groove which is in communication with the mixing chamber through a passage formed in the plunger. The high viscosity secondary fuel in the annular groove forms a seal between the plunger and the wall of the bore to prevent the low viscosity primary fuel from leaking past the seal.
