Abstract

Energy is an essential and vital input for economic activity. Energy demand is increasing due to ever increasing number of vehicles employing internal combustion engines. Building a strong base of energy resources is a pre-requisite for the sustainable economic and social development of a country. The world is presently confronted with the twin crises of fossil fuel depletion and environmental degradation. Indiscriminate extraction and lavish consumption of fossil fuels have led to reduction their underground resources. The Alternative fuels have become very important for both Spark Ignition (SI) and Compression Ignition (CI) engines owing to increased environmental protection concern, the need to reduce dependency on petroleum and even socioeconomic aspects. Fuels that are most used at present are Natural Gas, Liquefied Petroleum Gas (LPG) and biofuels, such as transesterified vegetable oils and alcohols. Liquefied Petroleum Gas is a mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles. LPG can be a major energy resource of the future due to its clean burning nature and eventual availability from renewable sources. LPG is widely regarded as a promising transportation fuel because it is clean and renewable. Biodiesel, as an alternative fuel, has many merits. It is derived from a renewable, domestic resource, thereby relieving reliance on petroleum fuel imports. It is biodegradable and non-toxic. Biodiesel has a relatively high flash point, which makes it less volatile and safer to transport. It provides lubricating properties that can reduce engine wear and extend engine life. These merits of biodiesel make it a good alternative to petroleum based fuel and have led to its use in many countries, especially in environmentally sensitive areas. The present work is an experimental investigation on 4 stroke CI engine in dual fuel mode with diesel as injected fuel, LPG as inducted fuel. The engine is also run with biodiesel (Waste Cooking Oil) separately. The engine is run under different operating conditions and in each case the optimum flow rates of LPG and biodiesel is determined for best efficiency. At each operating condition, the efficiency, exhaust gas temperature and other performance parameters are obtained and compared
