“…It is a widely held view that a heat exchanger is an efficient and easy device to measure heat losses. This approach has been implemented by recent researchers by considering external water to cool the main water from the engine [60,61,69]. The heat exchanger basically involves no work, kinetic or potential energy.…”

“…Some researchers have regarded heat losses to be due to the lubrication oil [62,70]; however, in this present study, the heat contributed by the lubrication oil will be neglected because it consumes only very small energy losses [59][60][61].…”

“…Once the assumptions have been made, the thermal balance of a particular engine can be made. Among the recent investigations of thermal balance of internal combustion engines is the perspective of Magno et al [60]. They investigated the energy balance of a three-cylinder CI engine operating on diesel (baseline fuel) and blended with 20% rapeseed methyl ester (B20).…”

“…Many researchers have done experiments on the performance and emissions of a DI diesel engine operating with different biodiesel blends. They found biodiesel fuels produced lower harmful pollutant emissions such as CO, HC and PM emissions, and slightly higher NO2 and NOx emissions [13][14][15][16][17]. The oxides of nitrogen are the most harmful parameter that affect the environment through acid rain, human diseases, etc.,.…”

In this study, the performance, emission and combustion characteristics of two different biodiesel blends produced from Mahua and pongamia methyl esters were compared with conventional diesel fuel. Methyl esters for experiment were produced by using a catalytic transesterification process and, compared the properties with ASTM standard values of biodiesel fuel and diesel fuel. The experiments were performed in a four stroke, single cylinder, common rail direct injection (CRDI) system assisted diesel engine at a constant speed of 1500rpm with varying injection pressure. During the tests, the specific fuel consumption, brake thermal efficiency, combustion and exhaust emissions of the CRDI diesel engine were measured. From the results it is clear that the HC, CO and smoke levels are drastically reduced when using the methyl ester blends. Especially in the case of MME20, NOx emissions was minimum when compared with other blends and it also found less amount of other harmful emissions like HC, CO and smoke.

“…Biodiesel is predominantly produced by a transesterification reaction; a process which is relatively simple and generates a fuel with properties similar to diesel. [12,13] Transesterification consists of a reaction between vegetable oil, or animal fat, and a primary alcohol in the presence of a catalyst, resulting in a mixture of alkyl esters of fatty acids (biodiesel) and glycerol. Excess alcohol in the reaction is necessary in order to increase the yield of esters.…”

Transesterification of waste cotton cooking oil (WCCO) is reported here. The GC-MS analysis of WCCO oil was studied and the major fatty acids were found to be Palmitic acid (28.26%) and Linoleic acid (43.14%). The molecular weight of the oil was 872.049 g/mol (GC-MS). The results showed maximum biodiesel yield of 96% when the reaction temperature, time, methanol/oil ratio and catalyst loading were fixed at 65 C, 45 min, 6:1 and 2% (wt.%) respectively. Partial purification of the biodiesel was performed for better engine performance and improved emission characteristics. The flash point and fire point of WCCO biodiesel were found to be 158 C and 165 C respectively. The brake thermal efficiency of WCCO10 biodiesel was 26.64% for maximum load and the specific fuel consumption for diesel was 0.3479 kg/kWh at maximum load. The use of biodiesel blends showed a reduction of carbon monoxide and hydrocarbon emissions and a marginal increase in nitrogen oxide emissions.
