Combustion, Noise and Vibrational Analysis of Linseed Biodiesel Fuelled Engine

With the rising population day-to-day there is surge in number of automobiles in the world. The huge increase in quantity of vehicles on track more demand for fuel. The widespread use of petrol and diesel leads to unadorned environmental problems like global warming, emissions of greenhouse gases, and reduction in their levels. Due to more demand and usage of fuels, stringent emission norms there is a need for development of renewable fuel. Engine vibration is higher in diesel engines, resulting in a shorter engine life cycle. Using a single cylinder compression ignition engine, an experimental study was conducted to measure combustion, noise, and vibration properties, as well as their similarities. The tests were conducted without maximum charge, using Linseed biodiesel, 10% and 20% (v/v) Linseed mix and baseline-mineral diesel. Samples of engine combustion noise were used with a microphone. In 3 direction measurements of motor acceleration, a triaxial accelerometer is utilized: vertical, lateral, and longitudinal. NI LabVIEW is used to collect data and perform research. Within the range of 0–100 Hz and three ways, higher peak amplitudes are observed for both diesel and linseed biodiesel at the frequency of 25 Hz. The highest level of combustion noise was observed with a 20% biodiesel mix, related to a longer delay in ignition and an increased rate of heat release. These findings were supported by other observations concerning combustion noise, ignition delay, and heat release rates.
