Vashi, Navi Mumbai shri.jklr@gmail.com Abstract—The Split-Cycle Engine changes the heart of the conventional engine by dividing (or splitting) the four strokes of the Otto cycle over a paired combination of one compression cylinder and one power cylinder. Gas is compressed in the compression cylinder and transferred to the power cylinder through a gas passage. The gas passage includes a set of uniquely timed valves, which maintain a prechargedpressure through all four strokes of the cycle. Shortly after the piston in the power cylinder reaches its top dead center position, the gas is quickly transferred to the power cylinder and fired (or combusted) to produce the power stroke. Split-cycle internal combustion engine claims have the potential to double fuel efficiency for same size engine, while reducing the manufacturing price by up to 50% which includes a built in dedicated compressor. Rather than using batteries and electric motors/generators to harness braking energy, the engine uses the air compressor. A split cycle engine includes a novel compressor apparatus driven by the combustion engine, a closed-cycle refrigeration system in cooperation with the compressor apparatus, and a pneumatic motor driven by compressed air from the compressor apparatus. Refrigerant in the compressor absorbs thermal energy from compressed air and assists in compressing the air. High-pressure air from the compressor is stored in a storage tank and may be used to drive the pneumatic motor or other auxiliary equipment in addition to providing high-pressure combustion air for the internal combustion engine
