“…Because it has been regulated electronically, LPG flow in the VPI can be further regulated based on vehicle dynamics, such as during deceleration and when driving down-way. LPG flow can be cut off or reduced for fuel savings under certain conditions [62], [63].…”

Article InfoThis article presents an overview of the technology status and market trends of LPG-fueled vehicles through the literature approach to re-evaluate their future. In the review, it is discovered that LPG vehicles are globally increasing, though with a concentration in some countries. Of the 25 countries included in the World LPG Association (WLPGA) annual report 2018, Turkey, Poland, India, Ukraine, and Mexico are the countries with the best LPG vehicle trends in average of 23%. with a long history of implementing LPG as an alternative fuel has experienced a decline in the 2013-2017 period by 17%. This was allegedly due to the penetration of diesel-fueled vehicles over the last ten years. Moreover, developed countries experiencing decline have succeeded in developing electric-based vehicles such as Hybrid Electric Vehicle (HEV), Plug-in hybrid electric vehicle (PHEV), Battery Electric Vehicles (BEV), and Fuel Cell Electric Vehicles (FCEV) due to stringent demands for emission standards. AbstrakArtikel ini menyajikan ulasan tentang status teknologi dan tren pasar kendaraan berbahan bakar LPG melalui pendekatan literatur untuk mengevaluasi kembali masa depan mereka. Dalam ulasan ini, ditemukan bahwa kendaraan LPG meningkat secara global, meskipun terkonsentrasi di beberapa negara. Dari 25 negara yang termasuk dalam laporan tahunan World LPG Association (WLPGA) tahun 2018, Turki, Polandia, India, Ukraina, dan Meksiko adalah negara-negara dengan tren kendaraan LPG terbaik dengan rata-rata 23%. Sementara itu, Australia, Jepang, Korea Selatan, Inggris, Belanda, Prancis, dan Jerman yang memiliki sejarah panjang menerapkan LPG sebagai bahan bakar alternatif telah mengalami penurunan 17% selama periode 2013-2017. Ini diduga karena penetrasi kendaraan berbahan bakar diesel selama sepuluh tahun terakhir. Selain itu, negara maju yang mengalami penurunan telah berhasil mengembangkan kendaraan berbasis listrik seperti Hybrid Electric Vehicle (HEV), Plug-In Hybrid Electric Vehicle (PHEV), Battery Electric Vehicle (BEV), dan Fuel Cell Electric Vehicle (FCEV) karena tuntutan ketat pada standar emisi.

“…The same indicator causes the replacement of diesel fuel during combustion. Because DME produces the least amount of NOx and CO, it acts as a clean fuel when burned in engines optimized for DME use [14]. Table 1 shows DME and other related fuels' physical properties and combustion characteristics.…”

Today, dimethyl ether (DME) is changing to ordinarily worn as a superb aerosol propellant and refrigerant for its eco-friendly characteristics. Lately, with the development of novel chemical energy in the coal industries, it has become a fascinating field of research as an alternative green fuel for diesel machines due to the high cetane number. The DME synthesis processes include catalytic dehydrating methanol in an adiabatic fixed-bed reactor. In this study, to investigate the chemical conditions of the methanol dehydration reaction, CFD simulations of the adiabatic reactor have been assessed. The advantage of the work is a sensitivity analysis was run to find the effect of pressure, kinetics, and velocity on the reactor performance. The results showed that using a γ-Al2O3 catalyst with selective mechanical properties and unique surface properties is a convenient choice for DME synthesis. The CFD simulation results also show that the laboratory data such as pressure, energy, and velocity in the adiabatic reactor meet the reaction requirements well, and deliberated a major vision of what happened in the reactor. Also, the graphs of the temperature profile with changes in physical properties pomp that methanol dehydration reaction strongly depends on environmental factors and gives different results under the influence of other conditions.
