2096647 9208888 PCTABS00013 A dual fuel injection arrangement for an internal combustion engine (1). Fuel is injected into the inlet manifold ducts to each engine cylinder via injectors (4, 5, 6, 7). An arrangement of valves allows selected supply of either a first fuel or a second fuel to the injectors (4, 5, 6, 7) via inlet fuel rail (8) and branch lines (9). Excess fuel is returned to each supply by way of return line (11). Electronic control units (31, 32) determine injection timing for the selected fuel dependent upon engine parameters for the first fuel and upon an adjusted timing for the second fuel where the adjustment takes account of the different characteristics of the second fuel compared with the first fuel. In particular there is disclosed an arrangement where the first fuel is gasoline and the second fuel is a liquified gas.
