“…Using a substitute of biological origin (biodiesel) for conventional diesel allows for achieving significant pollution improvement benefits, manifesting in the reduced emissions of PM, CO and hydrocarbons (HCs) compared with diesel [12]. It should be noted that the level of pollution reduction may vary, depending on whether biodiesel or another type of biofuel is used and the percentage of its replaceability in the fuel mixture, disregarding engine operating modes [13].…”

This article presents a change in the indicators of a compression ignition (CI) engine by replacing conventional diesel fuel (D100) with pure chicken fat (F100) and mixtures of these fuels. Mixtures of diesel and fat with volume ratios of 70/30, 50/50 and 30/70 were used. Research of the fuel properties was conducted. In order to reduce the fuel viscosity, blends of fat and diesel were heated. The experimental research was conducted at different engine loads with exhaust gas recirculation (EGR) both off and on. The conducted analysis of the combustion process revealed a significant change in the rate of heat release (ROHR) when replacing diesel with chicken fat. Chicken fat was found to increase the CO2 and CO emissions, leaving hydrocarbon (HC) emissions nearly unchanged. Having replaced the D100 with diesel and chicken fat mixtures or F100, a significant reduction in smoke and nitrogen oxide (NOx) emissions was observed when EGR was off. When EGR was on, the smoke level increased, but the blends with chicken fat reduced it significantly, and the increased fat content in the fuel mixture reduced the NOx emissions. The engine’s brake specific fuel consumption (BSFC) increased while the brake thermal efficiency (BTE) decreased, having replaced conventional diesel with chicken fat due to differences in the fuel energy properties and the combustion process.

“…However, the uncertainty as to the demand and policies has given rise to hesitation and signs of stagnation in the development [18]. Growing environmental pollution and limited fossil fuel reserves have encouraged research of the use of alternative renewable fuels for internal combustion engines [19].…”

The Article presents the results of the experimental research and numerical analysis of a compression ignition (CI) engine adapted for running on dual fuels of different composition (diesel and natural gas, diesel and biogas, biodiesel and natural gas, and biodiesel and biogas). The main goal was to find out the impact of different dual fuels on energy performance and emissions depending on the start of injection (SOI) of diesel and the crank angle degree (CAD). Pure conventional diesel fuel and second generation hydrotreated vegetable oil (HVO) (Neste) was used in the research. Natural gas contained 97 vol. % of methane. Biogas (biomethane) was simulated using a methane and carbon dioxide blend consisting of 60 vol. % of methane and 40 vol. % of carbon dioxide. Dual (liquid and gaseous) fuels were used in the tests, with the energy share of liquid fuels accounting for 40% and gas for 60%. The research results have shown that having replaced conventional diesel fuel with dual fuel, engine’s BTE declined by 11.9–16.5%. The use of methane in the dual fuel blend reduced CO2 volumetric fraction in the exhaust gases by 17–20%, while biomethane increased CO2 volumetric fraction by 10–14%. Dual fuel significantly increased CO and HC emissions, but NOx volumetric fraction decreased by 67–82% and smoke by 23–39%. The numerical analysis of the combustion process revealed changes in the ROHR (Rate of Heat Release) that affected engine efficiency and exhaust emissions was done by AVL (Anstalt für Verbrennungskraftmaschinen List) BOOST program.

“…In the first stage, LPG and air were mixed and delivered to the cylinder like the Otto engine but in a lean mixture. At the end of the compression, a small amount of diesel is sprayed in a diffusion flame to start simultaneous combustion of a combination of premixed and diffusion flames [45]- [51].…”

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.
