There has been a worldwide interest in the search for alternatives to petroleum-based fuels due to their depletion as well as due to concern for the environment. Vegetable oils have the capacity to solve this problem because they are renewable and lead to the reduction of environmental pollution. However, high smoke emissions and lower thermal efficiency are the main problems associated with the use of pure vegetable oils in diesel engines. In the present work, the performance characteristics, combustion and emission of the IC motor fed with 5% vol. Diethyl ether (DEE) mixed with Thevetia Peruvina seed oil (TPSO). Various performance, combustion and emission characteristics are measured, such as thermal efficiency and specific fuel consumption, volumetric efficiency, and it is revealed that 5% DEE mixed with biodiesel offers better performance, combustion and emission characteristics.
Historically, any change in the main energy source of a society has led to a revolution in lifestyle. Thus the domestication of animals and the easy availability of animal traction force were key to the transition of the hunter-gatherer society, where human muscle energy was the sole source of energy for the agricultural society. Before the industrial revolution, which began some 200 years ago, people depended essentially on manual and animal labor. Energy requirements were met through food intake. Life was simple and unsophisticated, and the environment was relatively clean and free of pollution. Then in 1785, the invention of the steam engine by James Watt of Scotland brought the industrial revolution. It was the beginning of the mechanical age or the age of the machines. The advent of the internal combustion engine in the late nineteenth century gave more impetus to the tread. Little by little the industrial revolution spread to the whole world and the need for a huge amount of energy realized. The discovery of large stocks of coal and steam engine heralded the industrial revolution with its mechanized production in the eighteenth century. Slowly the boilers and steam engines replaced the animal pulling current, the windmills and the water wheels. Thus seeds of phenomenal increase in the carbon dioxide content of the air were sown, and in the economies of nations. The second industrial revolution of the nineteenth century is often associated with numerous discoveries that lead to technological advances, the two most important being the invention of electricity and the modern use of petroleum products in internal combustion engines.
