Abstract
The article presents a pneumatic engine constructed by Angelo Di Pietro. 3D solid models of pneumatic engine components were presented therein. A directional valve is a key element of the control system. The valve functions as a camshaft distributing air to particular engine chambers. The construction designed by Angelo Di Pietro is modern and innovative. A pneumatic engine requires low pressure to start rotary movement. With the use of CFD software, the fields of velocity vectors’ distribution were determined. Moreover, the author determined the distribution of pressure values in engine inlet and outlet channels. CFD model studies on engine operation were conducted for chosen stages of operating cycles. On the basis of simulation tests that were conducted, the values of flow rates for the engine were determined. The distribution of pressure values made it possible to evaluate the torque value on the rotating shaft.

The air engine is used in industry and is a competition in relation to the electric motors
This article describes an innovative pneumatic engine designed by Angelo Di Pietro
In the chapter we will present the 3D project of pneumatic engine with air flow simulation and its model with numbers of actuators, valves, air distributors
Summary
The air engine is used in industry and is a competition in relation to the electric motors. This article describes an innovative pneumatic engine designed by Angelo Di Pietro. According to his assumptions, this engine has 94.5% efficiency, and constant high torque. In the chapter we will present the 3D project of pneumatic engine with air flow simulation and its model with numbers of actuators, valves, air distributors. This engine would be improved by using new numerical analyses described in papers [7-12]. This papers are good base of theoretical and industrial use
