“…The SFC is affected by engine speed, engine load, and injection pressure. Because at low load and low injection pressure the combustion process in the combustion chamber is poor [21]. Figure 4 which shows the 190 and 210 bar injection pressure the SFC has decreased in all loads, from 650-2600 Watt and at the same speed (1500 rpm).…”

Article InfoOn a single-cylinder diesel engine, injection pressure can be adjusted by changing the thickness of the injector shim. In this study, the injection pressure of 180 bar (standard), 190 bar (+1mm shim), and 210 bar (+2mm shim) was examined on a typical single-cylinder diesel engine with pure diesel fuel. The tests carried out at a constant engine speed of 1500 rpm with load variations of 650, 1300, 1950, and 3600 Watts to investigate the effect of injection pressure on output power, brake thermal efficiency (BTE), specific fuel consumption (SFC) and opacity. The results showed that increasing injection pressure could increase the output power by 19.3% and 17.4% by adding 1 mm and 2 mm shims, respectively. SFC decreased 1.97% and 12.3% compared to standard conditions and opacity with 2 mm shim was lower than 1 mm shim. In conclusion, increasing the injection pressure from 180 to 210 bar by adding 2 mm shim can improve the performance of a single cylinder diesel engine, which includes output power, brake thermal efficiency (BTE), specific fuel consumption (SFC) and opacity. AbstrakPada mesin diesel satu silinder, tekanan injeksi dapat diatur dengan mengubah ketebalan shim injektor. Dalam penelitian ini, tekanan injeksi 180 bar (standar), 190 bar (+1mm shim), dan 210 bar (+2mm shim) diperiksa pada mesin diesel satu silinder dengan bahan bakar diesel murni. Pengujian dilakukan pada putaran mesin konstan 1500 rpm dengan variasi beban 650, 1300, 1950, dan 3600 watt untuk menyelidiki pengaruh tekanan injeksi terhadap daya output, efisiensi termal rem (BTE), konsumsi bahan bakar spesifik (SFC) dan opasitas. Hasil penelitian menunjukkan bahwa peningkatan tekanan injeksi dapat meningkatkan daya output sebesar 19,3% dan 17,4% dengan menambahkanmasing-masing shim 1 mm dan 2 mm. SFC menurun 1,97% dan 12,3% dibandingkan dengan kondisi standar dan opasitas dengan shim 2 mm lebih rendah dari shim 1 mm. Kesimpulannya, meningkatkan tekanan injeksi dari 180 ke 210 bar dengan menambahkan shim 2 mm dapat meningkatkan kinerja mesin diesel satu silinder, yang meliputi daya output, efisiensi termal rem (BTE), konsumsi bahan bakar spesifik (SFC) dan opasitas.

“…Moreover, an interesting phenomenon in brake thermal efficiency in dual‐fuel mode diesel engine has been reported by Ambarita and Nathan et al Increasing the biogas energy ratio in diesel gradually does not increase the brake thermal efficiency gradually. As a result, it will have a maximum condition of operation and fuel composition.…”

Biodiesel fuel and biogas fuel as promising alternative energy sources for dual‐fuel‐mode diesel engine attract more researchers. Therefore, this study highlights the dual‐fuel mode (DFM) operation of diesel engine using biodiesel fuel from used cooking oil and simulated biogas fuel with different methane contents (M40, M60, M80, and M100) on the combustion, rate of heat release, combustion stability, and performance. The observation of diesel engine was conducted by varying the torques from 3.5 Nm, 10.5 Nm, 17.6 Nm, and 24.6 Nm and by varying the engine speeds from 1800 rpm, 2000 rpm, 2200 rpm, 2400 rpm, and 2600 rpm, respectively. It was found that in DFM at a low torque the thermal efficiency decreased, but biogas replacement, biogas energy, and sfc values increased. The relation of the results of biodiesel replacement, biogas energy ratio, and brake thermal efficiency with methane content ratio in DFM show that the methane content ratio has the maximum effect in DFM. In addition, the carbon dioxide content in the biogas can enrich the brake thermal efficiency. The combustion stability of all conditions (1.7%‐4.89%) is still acceptable.

“…Gad et al utilized palm oil biodiesel with diesel in a single cylinder diesel engine of power 5.775 kW and determined that with B20 (20% palm oil with 80% diesel blend), better reduction in HC (39ppm) and CO (0.062%) with a slight increase in NOx (194ppm) can be obtained than pure diesel [11]. Himsar Ambarita tested a small diesel engine with diesel-biogas dual fuel mode and found out that with raw biogas (60% methane concentration) and diesel, maximum brake thermal efficiency of 20% and reduced CO content in exhaust was obtained when compared to enriched biogas (70% methane concentration)-diesel mixture [12].K. Prashant and S. Srihari investigated the characteristics of cotton seed based biodiesel and diesel mixture at different proportions in a GL-400 diesel engine and observed an optimum engine performance with reduced NOx (600ppm), HC (38pppm) and CO (0.01%) concentration over the given range of increasing load with 20% biodiesel-diesel blend in a PCCI condition [13].…”

Emissions have become an important parameter, playing an extensive role in the selection of engines. To find out the alternatives for petroleum based fuels owing to their continuous depletion and the increase in emission rates, research works are being carried out continuously. The prime objective of this work is to study the effects butanol additive to the diesel-gasoline mixture fuelled to a CI engine. The operation is carried out by mixing butanol with diesel-4% gasoline mixture at different proportions and the mixtures are used to run a single cylinder APEX 240PE kirloskar make engine at constant speed under a series of load conditions. The performance characteristics of the fuel mixture used is obtained and the concentration of emissions present in the exhaust has been determined using an Emission Analyzer. The mixture can be used as an alternative fuel in diesel engines, thereby producing reduced emission rates.
