“…The use of DTBP showed a slight increase in energy efficiency, but an increasing in NOx and CO emissions was noticed. Venkateswarlu et al [5] studied and tested a single cylinder four stroke naturally aspirated direct injection air cooled diesel engine with exhaust gas recirculation and cetane improver Di Tertiary Butyl Peroxide (DTBP) as an additive to diesel-biodiesel blends. The combined effect of EGR and DTBP on Brake Thermal Efficiency(BTE), Brake Specific Fuel Consumption (BSFC), cylinder pressure and exhaust emissions is studied.…”

This study is motivated by the fact that the vegetable oils are being considered as the fuel of the future for the internal combustion engines, especially the compression ignition engines which are working with diesel as fuel. Different approaches for using the vegetable oils in CI engines as fuel are either to modify the oils to match with that of diesel to run successfully with these oils. Fuel additives are compounds formulated to enhance the quality and efficiency of the fuels used in motor vehicles. There are several benefits associated with the use of fuel additives. Di-tert butyl peroxide (DTBP) is effective for enhance the quality and efficiency of the fuels used in CI engine. The investigation was to check the feasibility of di-tert butyl peroxide as an additive in different blends of diesel and jetropha bio-diesel on engine performance. The short-term tests on an unmodified diesel engine were conducted using the bio diesel and di-tert butyl peroxide blends (0, 10, 20, 30, 40, 50, and 100 per cent and 0, 0.5, 1.0, 1.5, 2.0, 2.5 per cent) with diesel. The engine performance and emission characteristics were measured during the short-term test. In all types of fuel, with increased percentage of load, brake specific energy consumption (BSEC) of the engine was observed to be decreased, on the other hand brake thermal efficiency, fuel consumption rate, sound level (db.), exhaust temperature, and the engine exhaust emissions like CO2, CO, HC and NOx was increased, respectively.

“…In the area of fuels, Biodiesel proved its significant role as it has similarities with diesel fuel. Dominant diligence owing to its non-toxicity, biodegradability, renewability, with high flash point and a better minimization of greenhouse emissions are gained [3][4][5]. It is produced from animal fat,vegetable oil or pumpkin seed oil in the process of transesterification.The ready availability of pumpkin seed oil is one of its advantages most of the companies dump their waste oil into aquatic resources and it causes very harmful environmental problems.…”

In the current study, the primary components used are pumpkin seed oil biodiesel with diesel was tested in diesel engine and its performance, exhaust emissions, and its effects were observed. The pumpkin seed oil that is used to produce biodiesel undergoes transesterification process along with ethanol, sulphuricacid ,andNaOH catalysts . With blends like B0,B20,B40,B60,B80,and B100, the test on engine performance is obtained, and the reports exposed that, B40 is overlying blend among the other biodiesel blends. In addition, to enhance the performance characteristics of B20,B60,B80 by volume was combined with B40 blend. Due to lower heating characteristics of biodiesel, the observations of BTE for B40 is 4.6% lower than diesel. But the observations of BSFC for B40 is 7.3% higher than diesel. The heat emission rate ofB20,B40,andB60 are almost identical to diesel fuel ,apace with ,at higher loads B40 emitted37.5%less CO and NOx emission was raised at the rate of 95% when correlated to diesel fuel. However, It is observed that there is no major difference not much difference in the emissions (HC, NO, andCO) and characteristics of the engine when using the diesel fuel and Pumpkin seed biodiesel fuel blends

Abstract. This research analyzes the influence of UREA SCR System's mixer. The simplified modeling was facilitated to interpret current exhaust system. ANSYS of commercial program was utilized to analyze the fluid effects. Parameters were set up of four variable at 1,000rpm from 1,000rpm to 4,000rpm and three models were used for the analysis. Low pressure was measured at the end-central part of the mixer since the pressure is distributed from the central axis and towards the outside. By assessing the degree of uniformity, the uniformity expanded faster at high RPM and in low RPM, the flux itself is low so the uniformity gradually increase as it reached the latter part.
