Abstract: A compression-ignited, opposed-piston engine equipped for multi-fuel operation includes at least one cylinder, a pair of pistons slidably disposed in the cylinder for opposing movement between respective bottom and fop center locations, and spaced-apart intake and exhaust ports near respective ends of the cylinder. The pistons include end surfaces constructed to form a shaped combustion chamber when the pistons are near top center locations during a compression stroke of the engine. At least one gaseous fuel injector communicates with the bore of the cylinder through an injector site in the cylinder between the intake port and the exhaust port. At least one liquid fuel injector communicates with the bore through an injector site in the cylinder. A fuel injection system coupled to the at least one gaseous fuel injector and to the at least one liquid fuel injector is operable to cause the at least one gaseous fuel injector to inject a main charge of gaseous fuel when the pistons are between the bottom and top center locations and to cause the at least one liquid fuel injector to inject a pilot charge of liquid fuel.

Abstract: The present invention relates to a method for adjusting the power of a multiple-fuel internal combustion engine, wherein said method comprises modifying the gas distribution phases as well as the working volume of the cylinders. During idle or reduced-load operation modes of the engine, a signal from a control unit is used for performing a late closing of the inlet valves as well as an early closing of the outlet valves relative to standard values. During average-load operation modes, the fuel supply is increased together with the working volume of the cylinders while performing a late closing of the inlet valves as well as an early closing of the outlet valves relative to the idle and reduced-load operation modes. During nominal or close-to-nominal operation modes, the fuel supply is increased together with the working volume of the cylinders relative to average-load operation modes. The gas distribution phases of the outlet valves are also brought back to a standard value, while the gas distribution phases of the inlet valves are either brought back to a nominal value in the case of a spark-ignition engine or modified in order to obtain an incomplete introduction of a fresh load in the case of a compression-ignition engine.
