Research and Development Issues on Engineering Prototype of the Piston Hybrid Energy Converting Displacement Machines

The paper deals with the process of engineering prototype development of the piston hybrid energy machine. The whole development process is divided into three main stages: constructional design, design engineering, process engineering and manufacturing. In the first stage the design of piston hybrid displacement machines is proposed. A mathematical model of pump and compressor section working processes of the hybrid machine is developed. At the design stage a pneumohydraulic scheme and design documentation are developed. At the final stage, measures to improve manufacturability and reduce the cost of piston hybrid machines are considered.
