Liquefied Petroleum Gas (LPG) is an alternative fuel that has all key properties for the Spark Ignition (SI) engine. However, because of its properties, ignition timing on an LPG SI engine needs to be advanced from the reference angle to get the optimum performance. Therefore, this article presents the torque and power characteristics of a single piston LPG engine on variations of ignition timing. Evaluation of engine performance is carried out at the ignition timing of 15O, 17O, and 19O BTDC. The results showed the highest torque for LPG fuel was 10.64 Nm which was achieved at 3500 rpm with ignition timing of 19O BTDC, while the highest power for LPG fuel was 6.9 hp which was achieved at 5936 rpm with ignition timing of 19O BTDC.

The Stability

Throughout the history of combustion engines, the Heavy Duty Gas Turbine stands out as the most fuel-flexible prime mover in the field. This gas turbine (GT) is suited for a rich portfolio of gaseous fuels that include: natural gas, liquefied petroleum gas, coal and biomass-derived syngases, and a great variety of process gases with diverse compositions (hydrogen, carbon monoxide, olefins, etc.). Process gas fuels provide a promising array of alternative fuel opportunities in the major sectors of the industry such as the Coal, Oil & Gas, Steel, Chemical and Petrochemical branches. In an increasingly uncertain fuel environment, this significant match between gas turbine capabilities and the energy schemes of industrial plants can lead to further business opportunities.

Abstract Research on alternative fuel development gains importance day by day with respect to environmental concerns and issues. Alternative fuel research can yield a revolution for spark ignition (SI) engines due to their being one of the widely used energy systems worldwide. However, most studies miss the environmental impact and economy of alternative fuels, while focusing on performance and emissions characteristics of different alternative fuels. The present paper aims to introduce a novel perspective to evaluate fuels environmentally and economically. For this purpose, exhaust emissions from an SI engine fueled with gasoline, liquefied petroleum gas (LPG), and hydrogen are evaluated at a constant engine speed of 1500 rpm and the same equivalence ratio of 1.0, using the emissions index, power emissions index, energy emissions index, environmental impact, environmental cost, and environmental and social impact cost. At the end of the study, hydrogen is found to be less harmful than other fuels based on its environmental and social impact cost. On the other hand, hydrogen has the highest environmental cost at each ignition timing compared to both LPG and gasoline, whereas gasoline has the best performance from the viewpoint of environmental costs. The current paper is expected to be beneficial in evaluating or comparing different fuels in different engine types to those interested in energy, thermal studies, and environmental sciences.

In this paper modelling of extended-range electric vehicle powertrain. The model consists of sub-models of the investigated vehicle with its resistance forces, traction electric motor, range extender supplied with alternative fuel, and Li-Ion battery. Working point parameters of the range extender engine were defined to achieve low liquefied petroleum gas consumption. The model allowed to study possible parameters of vehicle range extender and battery size. The results show the higher influence of range extender power than battery energy capacity on the vehicle range. The defined range extender and battery parameters allow to significantly extend the vehicle range with low fuel consumption. This research provided ground for the further investigation of range extender control strategies.

Auto LPG is considered as an environment friendly fuel. Auto LPG powered cars emit less pollutants compared to the other conventional fuels by 15-20% less carbon dioxide (CO2) than their petrol- and diesel-motivated counterparts and emit virtually no nitrogen oxides (NOX) or particulate matter (PM). LPG is legal to use as an automobile fuel by Government of India by Liquefied Petroleum Gas (Regulation of use in Motor Vehicles Order, 2001 dated 1st August 2001 under instruction from the Hon’ble Supreme Court to reduce automobile pollution in Indian cities. There are more than 27 million Auto LPG vehicles in use around the world. In India, there are about 2.32 million vehicles running on Auto LPG in 2018 with 1300 filling stations in 500 cities. In Assam there are four refineries. At present Guwahati is considered as one of the most polluted city in India. So, Government policies and regulations is very mush essential to popularize auto LPG as an alternative fuel in Assam for improving the air quality as well as to combat climate change. In 2007, four numbers of Auto LPG dispensing stations were set up in Assam which is now in non-functional mode. In this paper a survey was conducted to analyze the awareness and extent of adoption and perception of Auto LPG in Guwahati City.

<p>ABSTRACT<br />This research was to analyze the technical effect of LPG compared to the gasoline by<br />measuring the engine and exhaust temperature, to calculate the fuel saving (efficiency) for a single<br />trip by measuring the specific fuel consumption, and to explicate the cost benefit from the use of<br />LPG compared to the gasoline for fishing operation. During the experimental test, the engine speed<br />was maintained at idling conditions of 1600, 2000, and 2500rev/min. Technically, the engine and<br />exhaust temperature decrease when running on LPG. The use of LPG as an alternative fuel to<br />gasoline can save on fuel consumption up to 26,35% and LPG makes operational cost more<br />efficiently due to the lower value of FC than that of gasoline. For a single trip, the cost from LPG<br />specific fuel consumption (sfc) value resulted Rp 5.610 while the gasoline resulted higher value<br />which makes Rp 9.632. With the difference of Rp 4.022, LPG can save cost as much as 41,76%<br />where cost savings in fuel expenditure can be used to reimburse the purchasing cost of converter<br />kit for 41,5 months or 3,46 years.</p><p><br />Key words: efficiency, fuel consumption, Liquefied Peltroleum Gas (LPG), temperature</p><p>-------</p><p><br />ABSTRAK</p><p>Penelitian bertujuan untuk menentukan secara teknis pengaruh penggunaan LPG<br />dibandingkan bensin premium pada motor bensin 6,5 HP, menghitung penghematan (efisiensi)<br />yang dapat dicapai dari penggunaan LPG dibandingkan bensin premium dalam satu kali operasi<br />penangkapan ikan dan menghitung keuntungan dari penggunaan LPG secara biaya dibandingkan<br />dengan bensin premium untuk kegiatan operasional penangkapan ikan. Selama uji coba motor<br />dioperasikan menggunakan bahan bakar bensin dan LPG secara bergantian dengan putaran 1600,<br />2000 dan 2500 rpm. Hasil penelitian menunjukkan bahwa penggunaan LPG secara teknis dapat<br />mereduksi suhu permukaan mesin, suhu gas buang dan konsumsi bahan bakar dibandingkan<br />motor yang dioperasikan menggunakan bensin premium. Selain itu rata-rata konsumsi bahan<br />bakar menjadi lebih hemat sebanyak 26,35% sehingga biaya operasional menjadi lebih efisien.<br />Dalam satu kali operasi penangkapan ikan didapat nilai spesific fuel consumption (sfc) LPG<br />sebesar Rp. 5.610 sedangkan nilai sfc bensin adalah sebesar Rp. 9.632. Dengan selisih sebanyak<br />Rp. 4.022 maka LPG bisa menghemat biaya sebanyak 41,76% dimana penghematan biaya<br />belanja bahan bakar dapat digunakan untuk mengembalikan biaya pembelian converter kit selama<br />41,5 bulan atau 3,46 tahun.</p><p><br />Kata kunci: efisiensi, konsumsi bahan bakar, Liquefied Petroleum Gas (LPG), suhu</p>
