Abstract
An opposed-piston internal combustion engine with one or more ported cylinders and uniflow scavenging includes fuel injectors supported at compound angles with respect to the cylinders in order to directly inject spray patterns of fuel in opposing directions through the side walls of the cylinders.
Claims14
An internal combustion engine including a plurality of cylinders, each cylinder including longitudinally separated exhaust and intake ports and a pair of pistons disposed in opposition to one another in a bore of the cylinder, in which, for each cylinder, a first fuel injector with an injector nozzle positioned near the longitudinal center of the cylinder is supported at a first compound angle with its nozzle at a first injection location, a second fuel injector with an injector nozzle positioned near the longitudinal center of the cylinder is supported at a second compound angle with its nozzle at a second injection location diametrically opposite the first injection location.
An opposed-piston engine including a plurality of row-aligned cylinders with longitudinally-separated exhaust and intake ports, two crankshafts, one disposed at each end of the cylinders, and a pair of pistons disposed in opposition to one another in a bore of each cylinder, wherein the pistons in exhaust ends of the cylinders are coupled to a first crankshaft and the pistons in intake ends of the cylinders are coupled to a second crankshaft, and in which for each cylinder:
- a first fuel injector with a nozzle is supported at a position near the longitudinal center of the cylinder at a first compound angle with its nozzle at a first injection location;
- and
- a second fuel injector with nozzle is supported near the longitudinal center of the cylinder at a second compound angle with its nozzle at a second injection location.
An opposed-piston engine, comprising:
- a support member supporting a plurality of row-aligned cylinders with longitudinally-separated exhaust and intake ports;
- a pair of pistons disposed in opposition to one another in a bore of each cylinder;
- at least one a first fuel injector supported at a position near the longitudinal center of a first cylinder at a first compound angle with its nozzle at a first injection location;
- and
- a second fuel injector supported near the longitudinal center of the first cylinder at a second compound angle with its nozzle at a second injection location.
