Abstract

A dual fuel system for a compression ignition internal combustion engine which is arranged to operate using a plant based fuel such as vegetate e oil. The system comprises a first fuel tank for a plant oil, a second fuel tank for a diesel fuel, an injector pump feeding at least one injector, a fuel selection valve, a heat exchanger for heating the plant oil after leaving the fuel tank and before being pumped to the injector and a re-circulating loop for feeding return fuel from the injector pump back to the injector pump. The fuel selection valve is arranged to select the fuel supplied into the recirculation loop on the basis of the viscosity or temperature of the fuel in the loop.
