“…Thus, the BTE may increase [3]. Moreover, BTE increases by 8% and 20% for LGO25 and 4.1% and 20.8% for neat LGO compared with the retarded and normal fuel injection timings respectively.…”

“…In Figure 4, cylinder pressure increases during the advanced injection timing compared with other injection timings for all blends of LGO-diesel fuels. The reason may be that most of the fuels burn in the premixed combustion phase, which leads to high peak cylinder pressure because of greater accumulation of fuel in the engine cylinder during the ignition delay period [3]. For pure diesel, the maximum cylinder pressure is 76.692 bar at advanced injection timing, which is higher by 15.5% and 18.71% than the normal and retarded injection timings respectively.…”

“…Compression ignition engines are widely used for agricultural, automotive, transportation and industrial sectors because of their better fuel economy and higher thermal efficiency [2,3]. Because of increasing concern about environmental issues and more stringent government regulations, many researchers have focused on the reduction of exhaust emission levels and improving fuel economy of internal combustion (IC) engines [2,[4][5][6][7].…”

“…A lot of research related to engine emission reduction and higher performance has used three important engine parameters: different injection pressure, injection timing and compression ratio [8][9][10][11][12]. The fuel injection timing is an important parameter that affects combustion and emissions [3,13].When the start of injection timing is advanced, the initial air temperature and pressure are lower, leading to an increase in ignition delay. The increase in ignition delay periods is the reason for the higher cylinder gas temperature and NO x emissions [13].…”

“…During the direct injection diesel engine operation, NO x increased but smoke, CO and HC decreased with an early direct injection. Some researchers [3,21,22] investigated the combined effect of advanced injection timing and various injection pressures and found that BMEP and BTE increased, while BSFC and exhaust gas temperature reduced significantly. CO and HC emissions were reduced but NO x emissions were increased with advanced injection timings.…”

In this study, the effect of neat lemongrass oil [1]-diesel blends on the performance, combustion and emission characteristics of a direct injection diesel engine was investigated with different injection timings of 21° (retarded), 23° (normal) and 27° (advanced) bTDC positions by using four different fuel blends of diesel, LGO25, LGO50 and neat lemongrass oil. The experimental results show that maximum cylinder pressure and heat release rate increased with advanced fuel injection timing for all test fuels. There was a reduction in BSFC and significant improvement in the brake thermal efficiency (BTE) with advanced injection timing. Emissions from the diesel engine such as smoke and hydrocarbon (HC) were reduced but NO X emission was very high with advanced injection timing compared with other injection timings. When the injection timing is advanced, ignition delay increases, which leads to the more prominent initial phase of combustion in the premixed region. In the light of the experimental results, the optimal injection timing determined for LGO-diesel blends was found to be 27° bTDC.

Internal combustion (IC) engines continue to maintain their position as principle prime mover for energy transformation especially in transportation and power sectors. Research on IC engines has many frontiers: optimum engine design to get better fuel utilization and mitigate spefici emissions; development of alternate fuels to reduce the dependence on fast depleting fossil fuels; use of oxygenated hydrocarbons in conventional compression ignition (CI) and spark ignition (SI) engines; development of reaction kinetics and thermal databases for different hydrocarbons to simulate combustion process in IC engines. This study reviews the status of the current research on all of the above mentioned frontiers. It lays down various parameters and their mutual dependencies and how they affect engine' performance and emissions characteristics. Various strategies that are employed to control these performance and emissions characteristics have been discussed. The application of different liquid (Alcohols and biofuels) and gaseous (natural gas and hydrogen) fuels as alternatives to the fossil fuels has been detailed. It also provides an insight into the development of various surrogates for gasoline and diesel fuels. Numerical modelling of the internal combustion engines and the application of emulsified nano‐fuels have also been discussed in detail.

The use of biodiesel along with other alternative fuel sources is expected to address the twin problems of pollution and energy security. This study investigates the effect of injection pressure (IP) on the performance, combustion, and emission characteristics of a four-stroke single cylinder direct injection diesel engine fuelled with a biofuel, namely cardanol-methanol-diesel blend (B20M10). The results are compared with baseline diesel operations under standard operating conditions. The biofuel blend B20M10 (20% cardanol, 10% methanol, and 70% diesel) is used as fuel, and the combustion, performance, and emission characteristics are investigated at IP levels of 180, 200, and 220 bar. The test results show that the optimum fuel IP is 220 bar with B20M10. At this optimized pressure, a reduction in CO, HC, and smoke emissions with an increase in the oxides of nitrogen (NO x ) and brake thermal efficiency (BTE) are noticed compared with 180 and 200 bar B20M10 operations. When compared with diesel (180 bar IP), B20M10 blend at 220 bar IP gives marginally lower BTE and lower CO and HC emissions, but oxides of nitrogen and smoke are slightly more.
