“…Figure 8 compares the CO emission of B5, B20, and B0 at different engine speeds. Figure 8 clearly shows that, over the entire range of speed, the macadamia biodiesel fuels provide lower CO emission than diesel fuel, which is supported by other studies [38]. Fuel sample B0 produces 1100 ppm and 2200 ppm CO emissions while B5 produces 1010 ppm and 1950 ppm and B20 produces 600 ppm and 1000 ppm at 800 rpm and 1400 rpm, respectively.…”

This paper investigated the prospects of biodiesel production from macadamia oil as an alternative fuel for diesel engine. The biodiesel was produced using conventional transesterification process using the base catalyst (KOH). A multi-cylinder diesel engine was used to evaluate the performance and emission of 5% (B5) and 20% (B20) macadamia biodiesel fuel at different engine speeds and full load condition. It was found that the characteristics of biodiesel are within the limit of specified standards American Society for Testing and Materials (ASTM D6751) and comparable to diesel fuel. This study also found that the blending of macadamia biodiesel-diesel fuel significantly improves the fuel properties including viscosity, density (D), heating value and oxidation stability (OS). Engine performance results indicated that macadamia biodiesel fuel sample reduces brake power (BP) and increases brake-specific fuel consumption (BSFC) while emission results indicated that it reduces the average carbon monoxide (CO), hydrocarbons (HC) and particulate matter (PM) emissions except nitrogen oxides (NO x ) than diesel fuel. Finally, it can be concluded that macadamia oil can be a possible source for biodiesel production and up to 20% macadamia biodiesel can be used as a fuel in diesel engines without modifications.

“…The reason for this is poor fuel utilization and incomplete combustion in the dual fuel engine. [37] The incomplete combustion of CNG causes white smoke emissions in the dual fuel engine. Improvement in gaseous fuel utilization at higher loads decreases the smoke emissions for the dual fuel engine.…”

The dual fuel engine shows significantly good results for brake thermal efficiency and brake specific energy consumption compared to the conventional diesel engine, at higher load. However, enhancements in NOx emissions were noticed. But it suffers with low thermal efficiency and high brake specific energy consumption, at low and intermediate loads. The application of exhaust gas recirculation (EGR) partially resolves the aforementioned problems of the dual fuel engine. In the present work, the dual fuel engine was operated with Jatropha oil methyl ester (JOME) as the pilot fuel for compressed natural gas (CNG). A comparative study has been done for various modes of operation: CNG-JOME dual fuel engine without EGR, CNG-JOME dual fuel engine with EGR, and conventional diesel engine at different operating loads. It was observed that the application of EGR improves the performance and emissions characteristics of the dual fuel engine compared to without EGR, particularly at low and intermediate loads. However, at higher loads, the use of EGR shows some adverse effect on performance and emissions characteristics, but decreased NOx emissions.

“…Also, it was concluded that the fuel blended with sal seed oil signiﬁcantly reduces the dependency of fuels derived from crude oil. Furthermore, environmental pollution was appreciably reduced . The performance and emissions of Jatropha curcas (JB10) and Moringa oleifera methyl ester (MB10) were assessed and compared with conventional diesel (B0).…”

“…Furthermore, environmental pollution was appreciably reduced. 4 The performance and emissions of Jatropha curcas (JB10) and Moringa oleifera methyl ester (MB10) were assessed and compared with conventional diesel (B0). Engine performance studies indicated that the BSFC significantly increases at brake power for JB10 and MB10 compared with B0 fuel.…”

The present study investigates the effect of Pithecellobium dulce biodiesel (PDBD) blends with diesel fuel on compression ignition (CI) engine emissions. Initially, PDBD was prepared by using a base transesteriﬁcation process. The GC‐MS, 1H NMR, and Fourier transform infrared characterization of PDBD was carried out, and fuel properties were determined. The experiments were conducted on a single cylinder, CI engine using three blended fuels: PDBD5 (5% biodiesel and 95% diesel), PDBD10 (10% biodiesel and 90% diesel), and PDBD20 (20% biodiesel and 80% diesel). The experimental outcomes revealed that 20% of PDBD reduces 19.64% carbon monoxide, 17.64% hydrocarbon, and 6.73% oxides of nitrogen emissions. Furthermore, from this study, it was inferred that the PDBD20 blend could be used as an alternative fuel for CI engines with no modiﬁcations in engine design.
