    Abstract: In split-cycle engines and air hybrid split-cycle engines, the sizing of the crossover passage is critical to engine efficiency. Efficiency can be improved by sizing the crossover passage volume to be small relative to the volume of the cylinders, and in particular relative to the volume of the compression cylinder. This allows for a higher pressure in the crossover passage, which extends the duration of sonic flow from the crossover passage into the expansion cylinder and increases combustion pressure. The methods, systems, and devices disclosed herein generally involve sizing the crossover passages, cylinders, or other components of a split-cycle engine or air hybrid split-cycle engine to improve efficiency.

    Abstract: In a two-stroke opposed-piston engine, a ported cylinder with a pair of opposed pistons is equipped with a decompression port including a valve and a passage with an opening through the cylinder wall.that is located between the cylinder's intake and exhaust ports. The decompression port enables the release of compressed air from the cylinder after the intake and exhaust ports are closed. The valve controls airflow through the passage, and is opened to permit compressed air to be released from the cylinder through the passage, and closed to retain compressed air in the cylinder. Engine braking is supported by release of compressed air through the decompression port into an exhaust channel when the pistons are at or near top dead center positions as the cycle transitions from the intake/compression stroke to the power/exhaust stroke. Compression release from the cylinder via the decompression port after intake and exhaust, port closure can also support other engine operations.
