ABSTRACT A compression ignition engine having a pilot fuel feed to the engine and a separate gaseous fuel feed characterized in that the separate gaseous fuel feed is controlled by means controlled by hydraulic pressure dependent on engine speed and/or engine load. A feature of importance is that for each engine speed when the engine is running the hydraulic pressure has a pre- determined maximum value, there being bleeding off circuitory or other means to enable reductions of hydraulic pressure below said maximum value for each speed. With such a means it is possible under low load conditions for engine speed governor means to cause the bleeding off circuitory or other means to cause a reduction in hydraulic pressure and hence gaseous fuel feed to engine at the particular engine speed. Such a compression engine retrofitted or otherwise to pro- vide the features of the present invention has application with both standing and mobile action.
