“…Transesterification process has been reported to be an effective method of viscosity reduction through the conversion of the waste cooking oil (WCO) to waste cooking oil methyl ester (WCOME) [10,11]. However, application of the resulting biodiesel in diesel engine leads to higher oxides of nitrogen (NO x ) emissions [12]. Experimental investigations by García-martín et al [13] and Abu-Jrai et al [14] reported notable increase in NO x emission with increasing quantities of waste cooking oil biodiesel in fuel blends with mineral diesel.…”

The effect of iron-doped cerium oxide (FeCeO2) nanoparticles as a fuel additive was experimentally investigated with waste cooking oil methyl ester (WCOME) in a four-stroke, single cylinder, direct injection diesel engine. The study aimed at the reduction of harmful emissions of diesel engines including oxides of nitrogen (NOx) and soot. Two types of nanoparticles were used: cerium oxide doped with 10% iron and cerium oxide doped with 20% iron, to further investigate the influence of the doping level on the nanoparticle activity. The nanoparticles were dispersed in the tested fuels at a dosage of 90 ppm with the aid of an ultrasonic homogenizer. Tests were conducted at a constant engine speed of 2000 rpm and varying loads (from 0 to 12 N.m) with neat diesel (D100) and biodiesel–diesel blends of 30% WCOME and 70% diesel by volume (B30). The engine combustion, performance, and emission characteristics for the fuel blends with nanoparticles were compared with neat diesel as the base fuel. The test results showed improvement in the peak cylinder pressure by approximately 3.5% with addition of nanoparticles to the fuel. A reduction in NOx emissions by up to 15.7% were recorded, while there was no noticeable change in unburned hydrocarbon (HC) emissions. Carbon monoxide (CO) emission was reduced by up to 24.6% for B30 and 15.4% for B30 with nano-additives. Better engine performance was recorded for B30 with 20% FeCeO2 as compared to 10% FeCeO2, in regard to cylinder pressure and emissions. The brake specific fuel consumption was lower for the fuel blend of B30 with 10% FeCeO2 nanoparticles, in low-to-medium loads and comparable to D100 at high loads. Hence, a higher brake thermal efficiency was recorded for the blend in low-to-medium loads compared to D100.

“…Increase in industrialization, transportation, and population are the prime causes of higher energy consumption. India has become the second‐biggest energy consumer in Asia since 2008, had already overtaken Japan in 2015 . In India, the transport sector consumes the largest share of energy demand and around 95% of transport energy is delivered by crude oil .…”

This study presents the comparative performance analysis of WCO15 and NEEM15 fuelled diesel engine using the experimental record data. Investigations are carried out with a natural aspirated, single-cylinder diesel engine at different load conditions. Exergetic and energetic parameters are determined by using the experimental data for both biodiesel blends at constant speeds. Exergy parameters namely exergy destruction, exhaust-exergy, cooling water-exergy, energy, and exergy distributions are compared. It is observed that the exergy variation follows a similar trend of their corresponding energy. At 100% load, brake thermal efficiency for NEEM15 and WCO15 is 30.88 and 32.35%, respectively. At 100% load, the exergetic efficiency for NEEM15 and WCO15 is 28.95 and 30.48%, respectively. NEEM15 gives higher exergy destruction as compared to WCO15, which is validated with the sustainability index for NEEM15. Evaluation of engine performance based on exergy is a better option instead of energy analysis only.

“…Some researchers have tested WCO and its blends as fuel in diesel engines (Ozsezen et al, 2009;Abu-Jrai et al, 2011;Kalam et al, 2011;Kumar & Jaikumar, 2014), while some have also used WCOME and its blends (Rao et al, 2008;Muralidharan & Vasudevan, 2011;An et al, 2013;Can, 2014;Kathirvel et al, 2016;). Generally, these WCO and WCOME products were blended with commercial diesel fuel.…”

The use of Waste Cooking Oil (WCO) as feedstock, and microwave heating technology are favored to reduce the cost of biodiesel. In order to identify the effect of using biodiesel from WCO Methyl Ester (WCOME) blends on diesel engine emissions and performance, WCOME blends were tested in a single-cylinder Direct Injection (DI) diesel engine at a constant speed of 2500 rpm and with five loads. For comparison, commercial diesel fuel, Petron Diesel Max (PDM), and biodiesel mixture from palm oil (POME) were also used. The performance and emission test results of the five test fuels: PDM, BP10, BP20, BW10, and BW20 were then compared with simulation results created by using GT-Power software. The experimental results indicated that using POME and WCOME blends led to increments in Brake Specific Fuel Consumption (BSFC) of up to 5.9% and reduction in Brake Thermal Efficiency (BTE) of up to 29.3% compare to PDM. These biodiesel blends also increased nitrogen oxide emissions and decreased carbon dioxide, carbon monoxide and hydrocarbon emissions for all engine loads at a constant speed of 2500 rpm. The experimental testing of the cylinder peak pressure demonstrates significant increase with the increase of engine load for the four test fuels. All the simulation graphs show similar trends.
