The Impact

The oils extracted from the waste plastic can be an admirable alternate for the compression ignition engines nevertheless they capitulate upper smoke emissions along with deprived performance when compared with diesel. The extraction of waste plastic oil (WPO) is attained through pyrolysis. The impact of accumulating a constituent hexanol (H), a biologically available biofuel is assessed. Three ternary mixtures, DE50-WPO40-H10, DE50-WPO30-H20 and DE50-WPO20-H30 has been deliberately primed for utilizing mutually a cast-off element (WPO maximum of 40 percent) along with a non-conventional part (hexanol maximum of 30 percent). The performance characteristics and emission factors of C.I engine fuelled with the above mix were assessed. The output specifies that hexanol inclusion makes significant reduction in smoke emission in addition to privileged HC emission in contrast to diesel. Inclusion of 10 percent hexanol in volume with WPO and diesel mixture retards the NOx emission considerably whilst match up to WPO as well as diesel individually. In spite of this, NOx emission is superior than the subsequent WPO with increased degree of hexanol converges. Brake thermal efficiency of the engine increases by way of escalating the hexanol portion in the blend while comparing with WPO. The fuel spending of concoction has been established to be reduced while compared to WPO. DE50-WPO40-H10 concoction showed a reduced amount of NOx as well as smoke emission.

Nozzle Opening

Experiments have been conducted to study the effect of nozzle opening pressure on the combustion process and exhaust emissions of a direct injection diesel engine fueled with orange skin powder diesel solution (OSPDS). Earlier investigation by the authors revealed that 30% OSPDS was optimum for better performance and reduced emissions. In the present investigation the nozzle opening pressure was varied with 30% OSPDS and the combustion, performance, and emissions characteristics were studied and compared with those of diesel fuel. The different nozzle opening pressures studied were 215 bar, 235 bar, and 255 bar. The results showed that the cylinder pressure with 30% OSPDS at 235 bar fuel nozzle opening pressure, was higher than that of diesel fuel as well as at other nozzle opening pressures. Similarly, the ignition delay was longer with shorter combustion duration in case of 30% OSPDS at 235 bar nozzle opening pressure. The brake thermal efficiency was higher at 235 bar than that of other fuel nozzle opening pressures with OSPDS and lower than that of diesel fuel. The NOx emission was higher and HC and CO emissions were lower with 30% OSPDS at 235 bar. The smoke emission was marginally lower at 235 bar and marginally higher at 215 bar than diesel fuel. The performance of the engine at 235 bar nozzle opening pressure was better with reduction in emissions except NOx than other nozzle opening pressures.

This paper presents the experimental work to investigate the effect of Re-entrant and Toroidal combustion chambers in a DICI Engine. The two combustion chambers namely Re-entrant combustion chamber (RCC) and Toroidal combustion chamber (TCC) were fitted in a 4.4 kW single cylinder Direct Injection Compression Ignition (DICI) engine and tests were conducted with diesel. The influences of the combustion chamber geometry characteristics on combustion, performance and emissions characteristics have been investigated. This investigation shows the peak pressure of re-entrant chamber is higher than that of toroidal chamber. The heat release rate and brake thermal efficiency for re-entrant chamber are slightly higher than that of toroidal chamber. Specific fuel consumption is lower for toroidal chamber than that of re-entrant chamber. The enhancement in reduction of carbon monoxide, hydrocarbon is observed for Re-entrant chamber compared to the Toroidal chamber. Oxides of nitrogen are reduced for toroidal chamber than that of re-entrant chamber.

Pyrolytic Oil

A growing interest in extracting oil from waste plastics has converged with rising demand for petro-fuels and issues in disposing of waste plastics. The characteristics of pyrolytic oil produced from plastic wastes were compared to diesel and found to be sufficiently similar to be used as an alternative fuel. In this paper, an attempt has been taken to enhance the combustion properties of waste plastic oil blended diesel following dispersion of nanographene particles. The performance and emissions of a single-cylinder direct injection compression ignition engine with compression ratios ranging from 16:1 to 18:1 was evaluated using 50, 70, and 100 ppm by using 50, 70, and 100 ppm by mass of nanographene dispersed in 20% waste plastic oil blended diesel without any engine modification. By supercharging the engine with nanographene at various compression ratios, the performance of a 20% plastic oil blended diesel is compared to that of a neat diesel. The brake thermal efficiency of 20% plastic oil blended 100 ppm graphene dispersed diesel fuel increased by 1.16% at a compression ratio of 17:1 when compared to diesel. The CO, HC, NOx emissions also dropped significantly by adding 100 ppm nanographene to WPO as compared to the other combinations of fuels.

The Impact

The performance and emissions characters of diesel engine behavior depend largely on several criteria, fuel injection nozzle plays a vital role in the proper combustion of diesel engines. This research analyzes the impact of a nozzle hole configuration on the features of a biodiesel-fuelled diesel engine. Therefore, the causes are dependent on the modification that the nozzle hole was selected from three-hole and five-hole nozzles, while the engine characteristics of the lemongrass biodiesel blend with diesel were examined. Lemongrass Biodiesel with 20 percent blend (LGB B20) has been investigated experimentally with different engine loads with respect to brake power, three hole, and five-hole nozzles. The experimental investigation showed an improvement in peak i.e. highest heat release rate of 12.5% for three and five-hole nozzle and brake specific fuel consumption of 15% is increased in single hole nozzle and it is observed it?s diminished in three and five holed nozzle. Further, the brake thermal efficiency is increased in the five-hole nozzle in comparison to the three hole nozzle at full load condition. Furthermore emission characteristics like HC, CO, and smoke are decreased with an increase in the number of nozzles, at the penalty of increase in NOx emissions has been observed.
