“…Diesel engine has been widely used as power source in many devices or vehicles to help human life such as generator, ship, car, train, heavy duty vehicle, and etc [1,2]. It has excellent superiority in high thermal efficiency, low fuel consumption, good endurance and durability compared to gasoline engine, gas turbine, steam turbine, and stirling engine [3][4][5].…”

Modification of combustion system from indirect injection (IDI) to direct injection (DI) was carried out on the two cylinder diesel engine, followed with tests for performance and emission. The modification from IDI to DI was conducted on a two cylinder diesel engine by removing the pre-chamber from the inside of the cylinder head, replacing the injector and its position to the top of the combustion chamber directly and also replacing the original piston with a piston that has a bowl on the crown. Performance and emission tests were conducted on 1,500 rpm with loads that vary from 0, 10, 20, 30, 40, 50, to 60 Nm. The investigation results of the diesel engine modification from IDI to DI showed several interesting phenomena. Further research is needed in order to increase the engine performance and reduce its emission.

“…It is also illustrated that EGR and main injection timing have a contrary influence for soot emissions as compared to NO emissions. This effect is attributed to the introduced high level EGR in combustion chamber giving rise to the reduction in oxygen availability for fuel combustion, and the retarded main injection would weaken atomization and vaporization of the injected fuel; furthermore, those will lead to incomplete combustion and increase in soot emission [25]. Figure 8 shows plots of the / ratio of ISFC against EGR rate, pilot fuel quantity, and main injection timing.…”

Some previous research results have shown that EGR (exhaust gas recirculation) rate, pilot fuel quantity, and main injection timing closely associated with engine emissions and fuel consumption. In order to understand the combined effect of EGR rate, pilot fuel quantity, and main injection timing on theNOx(oxides of nitrogen), soot, and ISFC (indicated specific fuel consumption), in this study, CFD (computational fluid dynamics) simulation together with the Taguchi method and the ANOVA (analysis of variance) technique was applied as an effective research tool. At first, simulation model on combustion and emissions of a light duty diesel engine at original baseline condition was developed and the model was validated by test. At last, a confirmation experiment with the best combination of factors and levels was implemented. The study results indicated that EGR is the most influencing factor onNOx. In case of soot emission and ISFC, the greatest influence parameter is main injection timing. For all objectives, pilot fuel quantity is an insignificant factor. Furthermore, the engine with optimized combination reduces by at least 70% forNOx, 20% in soot formation, and 1% for ISFC, in contrast to original baseline engine.

“…(2011) and Gomaa et al . (2011) showed that factors such as environmental and political concerns and volatility in oil prices will lead to gradual substitution of renewable energy for fossil fuels. The growing environmental concerns motivate various governments and other related institutions to mitigate the climate change through lesser carbon emission while substituting renewable energy consumption for traditional fossil fuels (Parker and Blodgett, 2008; Ibeto et al ., 2011).…”

In the context of recent energy transition from hydrocarbon molecules to electrons, this research aims to examine the degree of substitution between renewable energy sources and fossil fuels through a dynamic framework of time‐varying parameters under state‐space model. For this purpose, this research selects four major oil‐importing countries and employs annual time series data for crude oil imports, gross domestic product, crude oil price, renewable energy consumption, population growth, real effective exchange rate and industrial production index for each country in the sample while covering the period 1991–2018. The estimates reveal positive and significant income, population and industrial production index elasticities for most of the countries in the sample. In addition, this research finds negative and statistically significant elasticity between renewable energy consumption and demand for imported crude oil for India, China and Japan, although magnitude is very small. However, there is insignificant and little substitution for US data. This research is unique as to our knowledge there is no such study available before and it provides insights for policymakers in oil‐exporting countries to develop sustainable long‐term diversification strategies to reduce reliance on oil revenues.
