Experimental Investigation on single cylinder 4 stroke diesel engine operating with dual feul mode

Abstract

In the modern day world with the increase in industrialization and motorization the demand for the petroleum and its products has increased rapidly. The need of alternate fuels in internal combustion newlineengines throughout the globe is realized for the past few decades due to rapid exponential decrease in fossil fuel. With the undue exploitation and the consequent depletion of fossil fuel resources, the newlineusage of biodiesel fuels for IC engines has catapulted to higher levels. Concern over the human health, environmental effect, availability and cost of fossil fuels are motivating the researchers to newlineinvestigate alternative fuels for automobile industry. Bio-diesel made newlinefrom vegetable oils and animal fats are being used as a substitute to diesel fuel in order to have very low emissions. As a renewable, sustainable and alternative fuel for compression ignition IC engines, newline20% blend of cottonseed oil (CSO), hydrogen with diesel has been considered in this research work. The performance, combustion and emission characteristics have been thoroughly investigated with the newlineaforesaid fuel combination. The present work has been carried out deploying a single cylinder computer interfaced 4 stroke diesel engine, which has a provision for changing the injection opening pressure (IOP), a manifold newlinefor induction of hydrogen (H2) gas in suction stroke, varying compression ratio (CR) of the operation, it is fitted with a multigas MN-05 analyzer for testing the exhaust emissions. Trial runs on the engine were conducted at rated speed (1500 rpm) and power (3.5 kW) and identified the domain of the parameters.
