摘要： 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.

摘要： An opposed-piston engine has a cylinder block with a plurality of cylinders arranged inline, with each cylinder including an intake port longitudinally separated from an exhaust port. The engine's air handling system includes open intake and exhaust chambers in the cylinder block. The open chamber constructions eliminate the need for multi-pipe manifolds and smooth the flow of charge air.

摘要： An opposed-piston engine has a cylinder block with a plurality of cylinders arranged inline, with each cylinder including an intake port longitudinally separated from an exhaust port. The engine is equipped with an air handling system that includes intake and exhaust chambers inside the cylinder block. All of the cylinder intake ports are contained in the intake chamber to receive charge air therein. The intake chamber includes elongated air inlets opening through opposing sides of the cylinder block. The exhaust chamber includes at least one exhaust outlet opening through a side of the cylinder block; all of the cylinder exhaust ports are contained in the exhaust chamber to discharge exhaust thereinto.
