An auxiliary injector arrangement in a fuel supply system for an internal combustion engine. The auxiliary injector arrangement includes at least one injector mounted in the inlet manifold upstream or downstream of the throttle and adapted to supply fuel at times when the main fuel supply system cannot supply sufficient fuel. The main fuel supply system and the auxiliary injector may be operated on LPG, natural gas or petrol. The auxiliary injector may be a liquid fuel injector or gaseous fuel injector.

[ I claim:] [1.] An auxiliary injector arrangement in a dual fuel supply system for an internal combustion engine, the dual fuel supply system comprising a main fuel supply system to supply at least a first fuel using at least one main liquid fuel injector into at least an inlet manifold adjacent each engine cylinder of the engine, and an auxiliary fuel supply system, wherein:the inlet manifold includes a throttle body;the inlet manifold is divided downstream of the throttle body to supply air to each of the cylinders of the internal combustion engine;the auxiliary fuel supply system includes at least one injector for a second fuel, mounted in or adjacent the throttle body upstream or downstream of a throttle valve in the throttle body, and adapted to supply said second fuel at times when the at least one main injector cannot supply a sufficient amount of said first fuel; andthe second fuel, supplied by the auxiliary injector, is petrol.
