CYLINDER ARRANGEMENT FOR OPPOSED PISTON TWO-STROKE ENGINE

摘要

An opposed-piston, two-stroke engine is provided and includes a first cylinder having a first longitudinal axis, a first inlet port, and a first exhaust port. First pistons are slidably disposed within the first cylinder and are movable toward one another and away from one another. The engine additionally includes a second cylinder having a second longitudinal axis, a second inlet port, and a second exhaust port. The second cylinder is disposed adjacent to the first cylinder with the second inlet port being aligned with the first exhaust port in a first direction extending substantially perpendicular to the first longitudinal axis and the second longitudinal axis, and the second exhaust port being aligned with the first inlet port in the first direction. Second pistons are slidably disposed within the second cylinder and are movable toward one and away from one another.

主权项

1. An opposed-piston, two-stroke engine comprising:
a first cylinder having a first longitudinal axis, a first inlet port, and a first exhaust port; a pair of first pistons slidably disposed within said first cylinder and movable along said first longitudinal axis toward one another in a first mode of operation and away from one another along said first longitudinal axis in a second mode of operation; a second cylinder having a second longitudinal axis, a second inlet port, and a second exhaust port, said second cylinder disposed adjacent to said first cylinder with said second inlet port being aligned with said first exhaust port in a first direction extending substantially perpendicular to said first longitudinal axis and said second longitudinal axis, and said second exhaust port being aligned with said first inlet port in said first direction; and a pair of second pistons slidably disposed within said second cylinder and movable along said second longitudinal axis toward one another in said first mode of operation and away from one another along said second longitudinal axis in said second mode of operation.
