In this article, an experimental investigation, where the prototype of a new pneumatic vehicle is developed, analyzed, built and tested, is presented. The system consists of a novel compressed air system integrated with phase change materials for heat recovery purposes. The prototype is experimentally built and tested at the Ontario Tech. University in Oshawa. Three different phase change materials of polyethyleneglycol, paraffin and alkane mix are investigated for heat recovery purposes in the prototype where the paraffin option provides the best result. Furthermore, the maximum torque is found to vary between 21 and 44 Nm with changing shaft speed from 400 to 1300 rpm while the minimum torque fluctuates between 3 and 13 Nm with changing shaft speed in the same range. The supplementary battery power is 2.18 kW, and the turbine work output is found to be 1.25 kW with the recovered air which is provides 36% of the heat required to heat up the PCM heat exchanger. The total motor work consumed during operation is 18.36 kW, which can be defined as the acceptable capacity for the powertrain of a small-size city vehicle. The energetic efficiency for the compressed air vehicle is 59.5% while the exergetic efficiency becomes 51.0%, respectively.

“…AirPod, a green energy car, was invented by a French company of air-powered vehicles, in the 1990's, it was the successful application of a CAE [9]. The existing literatures showed that a great deal of investigations on kinds of CAE had been conducted by Chinese research scholars in the past 10 years [10][11][12][13][14]. Liu et al [10] reported that compressed air have similar energy density as Ni-H battery, the circulation efficiency of compressed air was 25-32.3% in practice and the characteristics of the CAE was suitable for driving a vehicle.…”

The purpose of this paper is to investigate working performance for a four-stroke compressed air engine via numerical studies. A mathematical model is developed to study the influence of several operative parameters on working performance. The mathematical model consists of thermodynamic model, each stroke model and dynamic model. In addition, a working principle and an experimental system of the compressed air engine are set up. The aims are: to introduce the novel four-stroke engine and to quantify the influence of rotational speed, supply pressure and supply temperature on working characteristics. The simulation and analysis show several meaningful results. The compressed air engine has higher cylinder pressure and work efficiency in lower speed stage, and the increase of the supply pressure can effectively improve indicated work and work efficiency. However, supply temperature has little effect on the performance of the compressed air engine. Therefore, the study of this work will provide a certain guidance function for further study on optimizing design of the compressed air engine.

“…Compressed air, as the second by importance energy medium in after electricity, is considered to drive a compressed air engine (CAE) because it is clean and inexhaustible [11]. Nowadays, in the field of the CAE, the relevant technologies have been researched by many domestic and foreign scholars [12][13][14][15], and there are many related literatures studying the CAE in the past several decades. These literatures focus on two main aspects: one is the feasibility analysis of the CAE and the other is the working process analysis of the CAE.…”

In order to reduce exergy loss and optimize exergy efficiency of a compressed air engine (CAE), a theoretical exergy analysis model of the CAE is proposed and a working principle of the CAE based on a conventional IC engine is described. In addition, exergy balance equations of the working process at different stages are setup. The effects of rotational speed, supply pressure and ambient temperature are revealed in the simulation analysis, which have important influences on the exergy efficiency of the CAE. All these analyses of this paper will provide a theoretical basis for further study on optimizing design of the CAE.
