A REVIEW ON THE EFFECT OF SUPERCHARGING ON THE DIESEL ENGINE WITH COTTON SEED OIL

Abstract

Diesel engines are the prime movers used in the transport and agricultural sectors for heavy duty vehicles. Diesel engines fulfill their requirements for energy from stored oils, i.e. petroleum products. The Twin Issues of both scarce resource depletion and atmospheric emissions caused by petroleum-based vehicles are prompting researchers to find a viable and immediate alternative to fossil fuels. The physical and combustion properties of vegetable oils are similar to those of petro-diesel fuel, and vegetable oils can be an immediate replacement candidate for stored fuels in this context. From the processing of the seeds of different plants, vegetable oils are produced and, hence, are renewable in nature. A country's sustainable development depends on the degree to which it manages and produces its own wealth. This also helps to preserve non-renewable petro-products that are depleting. Vegetable oils, however, would pose problems, such as fuel flow and poor atomization, due to inherent high viscosity and low volatility, and limit their direct use in engines without any modifications. The impact of supercharging on the output of a direct injection diesel engine using untreated cotton seed oil under varying injection pressures has been examined in the present investigation (IPs). In terms of brake specific fuel consumption (BSFC), exhaust gas temperature and smoke density, the engine's output is assessed. It is noted that when cotton seed oil is used as a fuel, when the engine is operated at the recommended IP and overcharging pressure of 0.4 bar (g) compared to the engine operated under naturally operated conditions, there is a decrease in BSFC of about 15 percent. The suggested IP of the engine is employed. The study found that while supercharging, cotton seed oil, in general vegetable oils, would best be used.
