“…Currently, owing to the high cost of He, most developments in inert gas cycle internal combustion engines are based on Ar. Existing research 32 has shown that hydrogen can achieve stable combustion in an Ar atmosphere, significantly improving engine thermal efficiency. Additionally, because N 2 was replaced, there was no NO x present in the combustion products, achieving truly clean combustion.…”

Review Future High-Efficiency and Zero-Emission Argon Power Cycle Engines: A Review Chenxu Wang , Shaoye Jin , Jun Deng , Weiqi Ding , Yongjian Tang , and Liguang Li ,* School of Automotive Studies, Tongji University, Shanghai 200092, China * Correspondence: liguang@tongji.edu.cn Received: 27 February 2023 Accepted: 23 May 2023 Published: 13 June 2023 Abstract: This paper reviews the theoretical and experimental researches on Argon Power Cycle (APC) engines. Hydrogen-fueled APC is an innovative power system for a high efficiency and zero emissions, which employs argon rather than nitrogen as a diluent. Due to the large specific heat ratio of argon, the thermodynamic efficiency of APC engines is significantly higher compared to conventional internal combustion engines. However, APC engines face the challenge of knock inhibition, especially when using hydrogen as a fuel. Therefore, this paper summarizes the strategies and technologies to suppress the knock of hydrogen-fueled APC engines, including using alternative fuels with greater anti-knock capacity, lean combustion, and water injection. Furthermore, some guidance opinions are also provided for reference about the development and industrialization of APC engines, such as ultra-lean combustion, which uses pistons with thermal insulation coatings, employing low-friction lubricants, and developing efficient multi-component membrane separation system for argon separation.

“…The automobile power source is the key point of the continuous development of the automobile industry [4]. Good alternative fuels, such as biodiesel, alcohols and compressed natural gas (CNG), have solved some environmental problems, as well as some energy problems [5][6][7]. However, since the beginning of 2013, many places in China had hazy weather, which slowly spread to the surrounding areas from Beijing, Tianjin as well as Hebei.…”

Emissions from motor vehicles have gained the attention of government agencies. To alleviate air pollution and reduce the petroleum demand from vehicles in China, the policy of “oil to gas” was vigorously carried out. Qingdao began to promote the use of natural gas vehicles (NGVs) in 2003. By the end of 2016, there were 9460 natural gas (NG) taxis in Qingdao, which accounted for 80% of the total taxis. An understanding of policy implementation for emission reductions is required. Experiments to obtain the taxi driving conditions and local parameters were investigated and an international vehicle emissions (IVE) localization model was established. Combined with vehicle mass analysis system (VMAS) experiments, the IVE localization model was amended and included the taxi pollutant emission factors. The result indicates that annual total carbon monoxide (CO) emissions from actual taxis are 6411.87 t, carbureted hydrogen (HC) emissions are 124.85 t, nitrogen oxide (NOx) emissions are 1397.44 t and particulate matter (PM) emissions are 8.9 t. When the taxis are running on pure natural gas, the annual emissions of CO, HC, NOx and PM are 4942.3 t, 48.15 t, 1496.01 t and 5.13 t, respectively. Unregulated emissions of annual total formaldehydes, benzene, acetaldehyde, 1,3-butadience emissions from an actual taxi are 65.99 t, 4.68 t, 1.04 t and 8.83 t. When the taxi is running on pure natural gas, the above unregulated emissions are 12.11 t, 1.27 t, 1.5 t and 0.02 t, respectively.
