Effect of Oxy-Hydrogen Addition in Diesel on Vibration Signals from Engine Crankshaft Bearing
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 2
Abstract
Oxy-hydrogen gas is known to improve engine performance and combustion characteristics. This paper presents study on effect of addition of oxy-hydrogen in diesel on vibration signals from crankshaft bearing of a twin cylinder diesel engine. Oxy-hydrogen is added in diesel at five different flow rates (100 (B1), 150 (B2), 200 (B3), 250 (B4) and 300 (B5) milliliters per minute). Changes in statistical parameters (Skewness, RMS value, Crest factor, Kurtosis and Peak amplitude) related to vibration signals are studied and compared with respect to non blended diesel (NB). 6.63% increase in skewness from crankshaft bearing is recorded with B3 and B2 flow rates. RMS of a vibration signal from crankshaft bearing increases by 3.53% with B1 flow rate. Crest factor of vibration signals from crankshaft bearing drops down by 20.59% with B3 flow rate. Kurtosis of vibration signal increases up to B3 blend and drops down with further addition. Peak amplitude of vibration signals from crankshaft bearing shows drop of 44.49% with B1 flow rate. Overall B3 flow rate of oxy hydrogen is observed to be most effective in reducing vibration signals.
