A FUEL INJECTOR FOR MULTI-FUEL INJECTION WITH PRESSURE INTENSIFICATION AND A VARIABLE ORIFICE

摘要

A multi-fuel injector has an internal pressure intensifier which has means to intensify fuels with different viscosities, cetane or octane numbers, with high viscosity fuel being used to intensify both itself and low viscosity fuels to high pressure for direct injection into combustion chamber. A combustion method using such a method of fuel injection is also disclosed. A multi-fuel injector with variable orifice nozzle and variable spray patterns is also disclosed.
