“…At this stage, the charge mixture combusts suddenly, which can sometimes cause knocking [50]. ID is reduced for WCO biodiesel for its high cetane number as it improves the auto-ignition property and causes complete combustion of the fuel [51]. The shorter ID enhances the en-gine's fuel consumption characteristics due to higher oxygen content in WCO biodiesel [52].…”

As non-renewable conventional fossil fuel sources are depleting day by day, researchers are continually finding new ways of producing and utilizing alternative, renewable, and reliable fuels. Due to conventional technologies, the environment has been degraded seriously, which profoundly impacts life on earth. To reduce the emissions caused by running the compression ignition engines, waste cooking oil (WCO) biodiesel is one of the best alternative fuels locally available in all parts of the world. Different study results are reviewed with a clear focus on combustion, performance, and emission characteristics, and the impact on engine durability. Moreover, the environmental and economic impacts are also reviewed in this study. When determining the combustion characteristics of WCO biodiesel, the cylinder peak pressure value increases and the heat release rate and ignition delay period decreases. In performance characteristics, brake-specific fuel consumption increases while brake-specific energy consumption, brake power, and torque decrease. WCO biodiesel cuts down the emissions value by 85% due to decreased hydrocarbon, SO2, CO, and smoke emissions in the exhaust that will effectively save the environment. However, CO2 and NOx generally increase when compared to diesel. The overall economic impact of production on the utilization of this resource is also elaborated. The results show that the use of WCO biodiesel is technically, economically, environmentally, and tribologically appropriate for any diesel engine.

“…Compared to unheated WCME, preheating helps increase BTE by 3.8%, decrease BSFC, and reduce CO and HC emissions by 15.6% and 13.5%, respectively, but NOx emission increases by 12.3%. Nanthgopal et al [19] also studied using 30% EGR in diesel engines using 100% WCME.…”

The use of biodiesel in blended mode is holding a more significant potential in making diesel engines environment-friendly. Published work specifies an optimum blend of biodiesel with diesel oil as B20. Further, the literature indicates that preheating biodiesel in the temperature range between 60°C to 120°C helps to increase the blend percentage up to 50%.In this experiment an effort has been made to use 100% Waste cooking oil methyl ester (WCME) biodieselby employing two stage heating in the temperature range from 100°C to 250°C. In the first stage the heater is immersed in fuel tank that heats biodiesel up to 70oC that lowers the viscosity and eases pumping. In the second syage, an electric preheater is installed along the high-pressure fuel line for achieving higher temperatures. The performance and emission results are encouraging and indicates that Brake Specific Fuel Consumption decreases by 5.4%, Brake Thermal Efficiency increases by 6.15%, Carbon Monoxide (CO) and unburnt hydrocarbon (HC) emissions fall by 38% and 25.5%, respectively. NOx has increased marginally by 4-6%.

“…Figure 8 show the emission of hydro carbon (HC) at different loads from the test engine by using diesel and PJ biodiesel blend with additive. HC emission was observed with unburned fuels due to inadequate temperature formation at near the cylindrical walls in the engine [12,22]. The lesser HC release occurs due to lower heat rejection by high in-cylinder temperature.…”

Up-to-the-minute researches of different countries have used conformist seed oils such as jatropha oil, coconut oil for the synthesis of biodiesel. In the present investigation, (pumpkin) Cucurbita pepo. L along Prosopis juliflora seed oil was used for the synthesis of mixed biodiesel with 5 ml Elaeocarpus Ganitrus (Rudraksha) as additive. Performance tests were conducted using biodiesel blend in water cooled CI engine and the emissions were analyzed using a five-gas analyzer. Pumpkin and Juliflora biodiesels were blended in equal ratio to form mixed biodiesel denoted by PJB. It was observed that there was 51% amplify in Brake Thermal efficiency and 33% diminution in Brake Specific Fuel consumption at the maximum load when compared to diesel for PJB20 blend with 5 ml additive. It was also noted that emission of CO bargain by 75%. CO2 bargain by 16.95%, HC compact by 49.2% and NO compact by 34.2% for PJB20 blend with 5 ml Rudraksha additive than that of diesel. The smoke opacity with respect to diesel was also noted to be concentrated by 6% for PJB20 with additive used as fuel in CI engine without any engine modification.
